Full Text

The present invention relates to novel imidazolidine derivatives of the formula !,

in which B, E, W, Y, R, R2, R3, R3D, e and h have the meanings given beiow. The compounds of the formula ! are valuable pharmaceutical active compounds which are suitable, for example, for treating inflammatory diseases, for example rheumatoid arthritis, or allergic diseases. The compounds of the formula i are inhibitors of the adhesion and migration of leukocytes and/or antagonists of the adhesion receptor VLA-4 belonging to the integrin group. They are generally suitable for treating diseases which are caused by, or associated with, an undesirable degree of leukocyte adhesion and/or leukocyte migration or in which cell-cell or celf-matrix interactions which are based on interactions of VLA-4 receptors with their ligands play a role. The invention furthermore relates to processes for preparing the compounds of the formula I, to the use of the compounds and to pharmaceutical preparations which comprise the compounds of the formula I.
The integrins are a group of adhesion receptors which play an essentia! role in cell-cell-binding and cell-extracellular matrix-binding processes. They possess an ajS-heterodimeric structure, have a wide cellular distribution and display a high degree of evolutionary conservation. The integrins include, for example, the fibrinogen receptor on blood platelets, which receptor interacts, in particular, with the RGD sequence of fibrinogen, and the vitronectin receptor on osteoclasts, which receptor interacts, in particular, with the RGD sequence of vitronectin or osteopontin. The integrins are divided into three major groups, i.e. the p2 subfamily, containing the representatives LFA-1, Mac-1 and p150/95, which are responsible, in particular, for

cell-cell interactions in the immune system, and the subfamilies (31 and fS3, whose representatives principally mediate the adhesion of cells to components of the extracellular matrix (Ruosiahti, Annu. Rev. Bbchem. 1988, 57,375). The integrins belonging to the p1 subfamily, which are also called VLA (very late (activation) antigen) proteins, include at least six receptors which interact specifically with fibronectin, collagen and/or laminin as iigands. Within the VLA family, the integrin VLA-4 (a4pi) is atypical insofar as it is mainly restricted to lymphoid and myeloid cells and in these cells is responsible for cell-cell interactions with a large number of other cells. For example, VLA-4 mediates the interaction of T lymphocytes and B lymphocytes with the heparin )l-binding fragment of human plasma fibronectin (FN). The binding of VLA-4 to the heparin !!-binding fragment of plasma fibronectin is based, in particular, on an interaction with an LDVP sequence. In contrast to the fibrinogen receptor or the vitronectin receptor, VLA-4 is not a typical RGD-binding integrin (Kilgerand Holzmann, J. Mo!. Meth. 1995, 73, 347).
Normally, the leukocytes which are circulating in the blood only exhibit a low degree of affinity for the vascular endothelial ceils which line the blood vessels. Cytokines which are released from inflamed tissue activate endothelial cells and thus the expression of a large number of cell surface antigens. These antigens include, for example, the adhesion molecules ELAM-1 (endothelial cell adhesion molecule 1; also called E selectin), which binds neutrophils, inter alia, 1CAM-1 (intercellular adhesion molecule 1), which interacts with LFA-1 (leukocyte function-associated antigen 1) on leukocytes, and VCAM-1 (vascular cell adhesion molecule 1), which binds various leukocytes, inter alia lymphocytes (Osborn et al., C6ll 1989, 59,1203). Like 1CAM-1, VCAM-1 is a member of the immunoglobulin gene superfamily. VCAM-1 (first known as iNCAM-110) was identified as an adhesion molecule which is induced on endothelial cells by inflammatory cytokines such as TNF and 1L-1 and lipopolysaccharides (LPS). Slices et al. (C6ll 1990, 60, 577) demonstrated that VLA-4 and VCAM-1 form a receptor-ligand pair which mediates the adhesion of lymphocytes to activated endothelium. The binding of VCAM-1 to VLA-4 does not take place here by means of an interaction of the VLA-4 with an RGD sequence

since VCAM-1 does not contain such a sequence (Bergelson et al., Current Biology 1995, 5, 615). However, VLA-4 also appears on other leukocytes, and the adherence of leukocytes other than lymphocytes is also mediated byway of the VCAM-1 A/LA-4 adhesion mechanism. VLA-4 thus represents a solitary exampte of a pi integrin receptor which, by way of the ligands VCAM-1 and fibronectin, plays an essential role both in cell-cell interactions and in cell-extraceliular matrix interactions.
The cytokine-induced adhesion molecules piay an important role in recruiting leukocytes into extravascuiar tissue regions. Leukocytes are recruited into inflammatory tissue regions by cell adhesion molecules which are expressed on the surface of endothelial cells and serve as iigands for leukocyte-cell surface proteins or protein complexes (receptors) (the terms ligand and receptor can also be used vice versa). Leukocytes from the blood have first of all to adhere to endothelial cells before they are able to migrate into the synovium. Since VCAM-1 binds to cells which carry the integrin VLA-4 {a4fJ1), such as eosinophils, T lymphocytes, B lymphocytes, monocytes and neutrophils, it, and the VCAM-1 A/LA-4-mechanism, are responsible for the function of recruiting such cells from the blood stream into infected regions and inflammation foci (Elices et al., C6ll 1990, 60, 577; Osbom, C6ll 1990, 62, 3; Issekutz et al., J. Exp. Med. 1996,183, 2175).
The VCAM-WLA-4 adhesion mechanism has been connected to a number of physiological and pathological processes, in addition to cytokine-induced endothelium, VCAM-1 is also expressed, inter alia, by the following cells: myoblasts, lymphoid dendritic cells and tissue macrophages, Theurnatoid synovium, cytokine-stimulated neural cells, parietal epithelial cells of the Bowman's capsule, the renal tubular epithelium, inflamed tissue in connection with heart and kidney transplant rejection, and intestinal tissue in connection with graft-versus-host disease. VCAM-1 is also found to be expressed on those areas of the arterial endothelial tissue which correspond to early atherosclerotic plaques in a rabbit model, in addition, VCAM-1 Is expressed on the follicular dendritic cells in human lymph nodes and Is present on stroma cells of the bone marrow, for example in the mouse. The latter finding suggests that VCAM-1 has a function in B cell development. Apart from on cells of

hematopoietic origin, VLA-4 is also found, for example, on melanoma cell lines, and the VCAM-1 A/LA-4 adhesion mechanism has been connected to the metastasis of such tumors (Rice et al.. Science 1989, 246,1303).
The principle form in which VCAM-1 occurs in vivo on endothelial cells, and which is the dominant form in vivo, is designated as VCAM-7D and carries seven immunoglobulin domains. The amino acid sequences.of domains 4, 5 and 6 resemble those of domains 1, 2 and 3. The fourth domain is removed, by alternative splicing, in another form, which is composed of six domains and which is designated here as VCAM-6D. VCAM-6D is also able to bind VLA-4-expressing cells.
Further information with regard to VLA-4, VCAM-1, integrins and adhesion proteins can be found, for example, in the articles by Kiiger and Holzmann, J. Mol. Meth. 1995, 73, 347; Elices, C6ll Adhesion in Human Disease, Wiley, Chichester 1995, p. 79 and Kuijpers, Springer Semin. Immunopathol. 1995,16, 379.
On account of the rale of the VCAM-WLA-4 mechanism in cell adhesion processes, which are of importance, for example, in infections, inflammations and atherosclerosis, attempts have been made to control these diseases, in particular, for example, inflammations (Osbom et al., C6ll 1989, 59, 1203), by intervening in these adhesion processes. A method for doing this is the use of monoclonal antibodies which are directed against the VLA-4. Monoclonal antibodies (Mabs) of this type, which, as VLA-4 antagonists, block the interaction between VCAM-1 and VLA-4, are known. Thus, the anti-VLA-4 Mabs HP2/1 and HP1/3, for example, inhibit the adhesion of VLA-4-expressing Ramos cells (B cell-like cells) to human umbilical cord endothelial cells and to VCAM-1-transfecied COS cells. In the same way, the anti-VCAM-1 Mab 4B9 inhibits the adhesion of Ramos cells, Jurkat cells (T cell-like cells) and HL60 cells (granulocyte-like cells) to COS cells which have been transfected with genetic constructs which cause VCAM-6D and VCAM-7D to bs expressed. In vitro data, obtained using antibodies which are directed against the cc4 subunit of VLA-4, show that the adhesion of lymphocytes to synovia! endothelial

cells, which adhesion piays a roie in rheumatoid arthritis, is blocked {van Dinther-Janssen etal"., J. Immunol. 1991,147,4207).
In vivo experiments have demonstrated that antkx4 Mab can inhibit an experimental autoimmune encephalomyelitis. A monoclonal antibody directed against the a4chain of VLA-4 likewise blocks the migration of leukocytes into an inflammation focus. The ability of antibodies to exert an effect on the VLA-4-dependent adhesion mechanism has also been examined in an asthma mode!, in order to investigate the roie of VLA-4 in recruiting leukocytes into inflamed lung tissue (WO-A-93/13798). The administration of anti-VLA-4 antibodies inhibited the !ate phase reaction and the airway hyperreaction in allergic sheep. The significance of VLA-4 as a target for treating asthma is discussed in detail in Metzger, Springer Semln. Immunopathoi. 1995, 16,467.
The VLA-4 dependent cell adhesion mechanism has also been investigated in a primate model of inflammatory bowel disease (IBD). In this model, which corresponds to ulcerative colitis in humans, the administration of anti-ct4 antibodies resulted in a significant reduction in the acute inflammation.
In addition to this, it has been demonstrated that VLA-4-dependent cell adhesion plays a roie in the following clinical conditions, including the following chronic inflammatory processes: rheumatoid arthritis {C1-onstein and Weismann, Arthritis Rheum. 1993, 36,147; Elices et ai., J. Clin. Invest. 1994, 93, 405), diabetes meliitus (Yang etal., Proc. Natl. Acad. Sci. USA 1993, 90, 10494), systemic lupus erythematosus (Takeuchi et al., J. Clin. Invest. 1993, 92, 3008), delayeC1-type allergies (type IV allergy) (Eiices et al., Clin. Exp. Rheumatol. 1993,11, S77), multiple sclerosis (Yednock et al., Nature 1992, 356, 63), malaria (Ockenhouse et al., J. Exp. Med. 1992,176, 1183J,.atherosclerosis (O'Brien et al., J, Clin, invest. 1993, 92, 945; Shin et al., Circ. Res. 1999, 84, 345), transplantation (Isobe et a!., Transplantation Proceedings 1994, 26, 867), various malignancies, for example

melanoma (Renkonen et al„ Am. J. Pathol. 1992,140, 763), lymphoma (Freedman et al.r Blood 1992, 79, 206) and others (Albelda et a!., J. C6ll Biol. 1991,114,1059).
The interaction of VLA-4 with VCAM-1 and fibronectin has been connected to some pathophysiological processes in cardiovascular diseases, tn an in vitro eel! system, immigrated neutrophils inhibit the shortening (negative inotropy)of cardiomyocytes by 35%. It was possible to inhibit this negative inotropic effect of neutrophils by an anti-a4 antibody, but not an anti-CD18 antibody, (Pobn et al., Circ. Res. 1999, 84, 1245). The importance of VLA-4 in the pathogenesis of atherosclerosis has been demonstrated in a mouse model of atherosclerosis. Thus, the CS-1 peptide, which is directed against the VLA-4-binding site on fibronectin, inhibits the recruiting of leukocytes and the accumulation of fat in the aorta and consequently the formation of atherosclerotic plaques in atherogenicallyfed LDL receptor-knockout mice (Shih et al., Circ. Res. 1999, 84, 345). Using the same CS-1 peptide, it was furthermore possible to show in a heterotopic rabbit heart transplantation mode! that the formation of a transplant vascuiopatny can be significantly reduced by blockade of the interaction of VLA-4 and fibronectin (Moiossi et al., J. Clin. Invest. 1995, 95, 2601). WO-A-00/02903 describes CS-1 peptidomimetics which contain an aspartic acid unit, or a derivative thereof, in the molecule and which inhibit the binding of VLA-4 to the CS-1 sequence of the matrix protein fibronectin.
Accordingly, blockade of VLA-4 by suitable antagonists to offers possibilities of achieving an effective treatment, in particular, for example, of treating various inflammatory conditions, including asthma and IBD. The particular relevance of VLA-4 antagonists for treating rheumatoid arthritis follows, as has already been stated, from the fact that leukocytes from the blood have first of all to adhere to endothelial cells before they are able to migrate into the synovium, and from the fact that the VLA-4 receptor plays a role in this adhesion. It has already been mentioned above that inflammatory agents induce VCAM-1 on endothelial cells (Osbom, C6ll 1990,62, 3; Stoolman, C6ll 1989,56,907), and that various leukocytes are recruited into areas of infection and foci of inflammation. In this connection, T cells adhere to an activated endothelium mainly via the LFA-1/iCAM-1 and VLA-4/VCAM-1 adhesion

mechanisms (Springer, C6ll 1994,76, 301). In rheumatoid arthritis, the binding capacity of VLA-4 for VCA.M-1 is increased on most synovia! T celis (Postigo et al., J. Clin. Invest. 1992, 89,1445). In addition, an increased adhesion of synovial T cells to fibronectin has been observed (Laffon et al., J. Clin. Invest. 1991, 88, 546; Morales--Ducret et al., J. Immunol 1992,149,1424). VLA-4 is thus up-reguiated both with respect to its expression and with respect to its function on T lymphocytes of the rheumatoid synovial membrane. By blocking the binding of VLA-4 to its physioiogical ligands VCAM-1 and fibronectin, articular inflammatory processes can be effectively prevented or alleviated. This is aiso confirmed by experiments, using the antibody HP2/1, which were carried out on Lewis rats suffering from adjuvant arthritis and in which effective disease prevention was observed (Barbadillo et al., Springer Semin. Immunopathol. 1995,16,427). VLA-4 is thus an important therapeutic target molecule.
The abovementloned VLA-4 antibodies, and the use of antibodies as VLA-4 antagonists, are described in the patent applications WO-A-93/13798, WO-A-93/15764, WO-A-94/16094, WO-A-94/17828 and WO-A-95/19790. The patent applications WO-A-94/15958, WO-A-95/15973, WO-A-96/00581, WO-A-96/06108 and WO-A-96/20216 describe peptide compounds which are VLA-4 antagonists. However, the use of antibodies anC1-peptide compounds as pharmaceuticals suffers from disadvantages, for example lack of oral availability, easy degradabil'rty or an immunogenic action on longer-term administration, and thus there is a need for VLA-4 antagonists possessing a favorable property profile for use in the therapy and prophylaxis of various disease states.

Het is a residue of a monocyclic or polycyclic, 4-membered to 14-membered,
aromatic or non-aromatic ring which contains 1, 2, 3 or 4 identical or different ring
heteroatoms from the series nitrogen, oxygen and sulfur and can optionally be
substituted by one or more identical or different substituents;
e and h are, independently of each other, 0 or 1;
n is 1 or 2, where, when they occur more than once, the numbers n are independent
of each other and can be identical or different;
in all their stereoisomer^ forms and mixtures thereof in all ratios, and their
physiologically tolerated salts.
When residues or substituents can occur more than once in the compounds of the formula I, they all can, in a general manner, independently of each other have the given meanings and be identical or different. If residues are made up of two or more components such as, for example, arylalkyl, the free linkage via which the residue is

bonded is located on the component which is specified at the right-hand end of the name, that is, in the case of the arylalkyl residue, on the alky! group to which an aryl group is then bonded as a substituenl •
Alkyl residues can be straight-chain or branched. This also applies when they carry substituents or occur as substituents of other residues, for example in alkoxy residues, alkoxycarbonyl residues or arylalkyl residues. Examples of suitable alkyl residues are methyl, ethyl, n-propyl, n-butyl, n-pentyi, n-hexyl, n-heptyl, n-octyl, n-nonyl, n-decyi, n-undecyl, n-dodecyl, n-tridecyl, n-tetradecyi, n-pentadecyl, n-hexadecyl, n-heptadecyl, n-octadecyi, isopropyl, isobutyi, isopentyl, isohexyl, 3-methylpentyi, neopentyf, neohexyl, 2,3,5-trimethylhexyl, sec-butyl, tert-butyl and tert-pentyi. Preferred alkyl residues are methyl, ethyl, n-propyl, isopropyl (= 1-methyiethyl), n-butyl, isobutyi (= 2-methylpropyl), sec-butyl, tert-butyl (= 1,1-dimethylethyl), n-pentyl, isopentyl, n-hexyl and isohexyl. If alkyl residues are substituted by fluorine atoms, they can then, unless otherwise indicated, contain, for example, 1,2,3, 4, 5, 6 or 7 fluorine atoms. For example, a methyl group in a fluorine-substituted alkyl residue can be present as a trifiuoromethyl group. Examples of fluorine-substituted alky! residues are trifiuoromethyl, 2-fluoroethyl, 2,2,2-trifiuoroethyl and heptafluoroisopropyl.
Alkylene residues {= alkanediyl residues), that is divalent residues which are derived from an alkane, can likewise be straight-chain or branched. They can be bonded via any desired position. Examples of alkylene residues are the divalent residues which correspond to the abovementioned monovalent residues, for example methylene, ethylene (= 1,2-ethylene or 1,1-ethylene), trimethylene (= 1,3-propylene), tetramethylene (= 1,4-butylene), pentamethylene, hexamethylene, or methylene or ethylene which is substituted by alky] residues. Examples of substituted methylene are methylene groups which carry a methyl group, an ethyl group, an n-propyl group, an isopropyl group, an n-butyl group, an isobutyi group, a tert-butyi group, an ri¬pe ntyl group, an isopentyl group, an n-hexyl group or two methyl groups as substituents. Substituted ethylene can be substituted on the one or on the other carbon atom or on both carbon atoms.

Alkenyl residues and alkenylene residues {= alkenediyi residues) and alkyny! residues can also be straight-chain or branched. Examples of alkenyl residues are vinyl, 1-propenyl, allyl, butenyl, 2-methyl-1-propenyl, 2-methyl-2-propenyl and 3-methyl-2-butenyl. Examples of alkenylene residues are vinylene, propenylene and butenylene. Examples of alkynyl residues are ethynyl, 1-propynyl and propargyl.
Examples of cycloaikyl residues are cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyi,. cycioheptyl, cyclooctyl, cydononyl, cyclodecyl, cycloundecyl and cyclododecyi, which can also be substituted by, for example, one or more, for example one, two, three or four, identical or different {C1-C4)-alky! residues. Examples of substituted cycloaikyl residues are 4-methyicyclohexyi and 2,3-dim ethyl cyclopentyl. These explanations with regard to the monovalent cycloaikyl residues apply, in a corresponding manner, to cycioalkylene residues (= cycloalkanediyl residues), that is divalent residues which are derived from cycloalkanes. Cycioalkylene residues can be bonded via any desired positions.
Bicycloalkyl residues and tricycloalkyl residues and the 6-membered to 24-mernbered bicyclic and tricyclic residues which represent R16 are formally obtained by abstracting a hydrogen atom from bicycles and tricycles,-respectively. The underlying bicycles and tricycles can contain only carbon atoms as ring members, that is they can be bicycioalkanes or tricycioalkanes, or they can, in the case of the residues which represent R16, also contain one to four identical or different ring heteroatoms from the series nitrogen, oxygen and sulfur, that is they can be aza-, oxa- and thia-bicycloalkanes and -tricycioalkanes. When ring heteroatoms are present, preferably one or two ring heteroatoms, in particular nitrogen atoms or oxygen atoms, are present The ring heteroatoms can occupy any desired positions in the bicyclic or tricyclic system; they can be present in the bridges or, in the case of nitrogen atoms, at the bridgeheads as well. Both the bicycioalkanes and tricycioalkanes and also their heteroanalogs can be completely saturated or contain one or more double bonds. Preferably, they are completely saturated or contain one or two double bonds; particularly preferably, they are completely saturated. Both the

bicycloalkanes and tricycioalkanes and also the heteraanalogs, and both the saturated and the unsaturated representatives, can be unsubstituted or they can be substituted in any desired and suitable positions, by one or more oxo groups and/or one or more, for example one, two, three or four, identical or different (C1-CiJ-alkyl * ■ groups, for example methyl groups and/or isopropyl groups, preferably methyl groups. The free bond of the bicyciic or tricyclic residue can be located in any arbitrary position in the molecule; the residue can consequently be bonded via a bridgehead atom or an atom in a bridge. The free bond can be located in any stereochemical position, for example in an exo position or an endo position.
Examples of parent bicyciic ring systems from which a bicyciic residue can be derived, are norbomane (= bicycio[2.2.1]heptane), bicyclo[2.2.2]octane and bicyclo[3.2.1]octane; exampies of unsaturated systems or substituted systems or systems which contain heteroatoms are 7-azabicyio[2.2.1]heptane, bicyclo[2.2.2.]oct-5-ene and camphor (= 1,7,7-trimethyl-2-oxobicydop.2.1]heptane).
Examples of tricyclic ring systems from which a tricyclic residue can be derived are twistane (= tricycio[4.4.0.03,B]decane), adamantane {=tricyclo[3.3.1.13,7]decane)( noradamantane(=tricyclo[3.3.1.03,7]nonane}, tricyclop^.LO^heptane, tricyclo[5.3.2.04-9]dodecane, tricyclo[5.4.0.02,9]undecane and tricyclo[5.5.1.03'11]tridecane.
Bicyciic or tricyclic residues are preferably derived from bridged bicycles and tricycies, respectively, that is from systems in which rings'possess two or more than two atoms in common. Unless otherwise indicated, preference is furthermore given to bicyciic or tricyclic residues having from 6 to 18 ring members, with particular preference being given to those having from 6 to 14 ring members, and very particular preference being given to those having from 7 to 12 ring members. Specifically preferred bicyciic or tricyclic residues which can, for example, represent a bicycloalkyl group or a tricycloaikyl group, are the 2-norbornyl residue, both that having the free bond in the exo position and that having the free bond in the endo position, the 2-bicyclo[3.2.1]octyl residue, the adamantyi residue, both the

1-adarnantyi residue and the 2-adamantyl residue, the homoadarnantyl residue and the noradamantyi residue, for example the 3-noradarnantyI residue. Moreover preferred are the 1-adamantyi residue and the 2-adamanty| residue.
The above clarifications with regard to the monovalent bicycloalkyl residues and tricycloalkyl residues apply, in a corresponding manner, to the divalent bicycloalkylene residues and tricycloalkylene residues (= bicyckoalkanedtyl residues and tricydoalkanediyl residues).
Examples of (C6-C-i^-aryl groups are phenyl, naphthyl including 1-naphthyl and 2-naphthyl, biphenylyi including 2-biphenylyl, 3-biphenylyl and 4-biphenylyi, anthryl and fluorenyl; examples of (C6-Cio)-aryl groups are 1-naphthyl, 2-naphthyl and phenyl. Biphenylyi residues, naphthyl residues and, in particular, phenyl residues are preferred aryl residues. Aryl residues, in particular phenyl residues, can be unsubstituted or be substituted once or more than once, for example, once, twice, three times or four times, by identical or different residues. Substituted aryl residues, in particular phenyl residues, are preferably substituted by substituents from the series {C1-C3)-a!kyl, in particular (C1~C4)-alkyl such as methyl; (C1-Ca)-alkoxy, in particular (C-t-C1-alkoxy such as methoxy; (C1-CgJ-alkoxy, in particular (C1-C4)-alkoxy, which is substituted by one or more fluorine atoms, for example 1,2, 3,4 or 5 fluorine atoms, such as trifluoromethoxy; halogen; nitro; amino; trifluoromethyl; hydroxy!; hydroxy-(C-r£t}-alkyl, such as hydroxymethyt or 1-hydroxyethyl or 2-hydroxyethyl; methyienedioxy; dimetbylmethylenedioxy; ethylenedioxy; formyi; acetyl; cyano; hydroxy carbonyl; aminccarbonyl; (C1-C1-alkoxycarbonyl; phenyl; phenoxy, benzyl; benzyloxy; and tetrazoiyl.
In monosubstituted phenyl residues, the substituent can be located in the 2 position, the 3 position or the 4 position. Phenyl which is' substituted twice can contain the substituents in the 2,3 position, the 2,4 position, the 2,5 position, the 2,6 position, the 3,4 position or the 3,5 position. In phenyl residues which are substituted three times, the substituents can be located in the 2,3,4 position, the 2,3,5 position, the 2,4,5 position, the 2,4,6 position, the 2,3,6 position or the 3,4,5 position.

The above explanations apply in a corresponding manner to substituted aryl residues in groups such as, for example, arylalkyl, arylcarbonyl, etc. Examples of arylalkyl

residues are 1- and 2-naphthylmethyl, 2-, 3- and 4-biphenylylmethyi and 9-fluorenylmethyl and, in particular, benzyl, all of which can also be substituted. Examples of substituted arylalkyl residues are benzyl residues and naphthylmethyl residues which are substituted in the aryl moiety by one or more (C1-C8)-alkyl residues, in particular (CVC1--alkyl residues, for example 2-t 3- and 4-methylbenzyI, 4-isobuty!benzyl, 4-tert-butylbenzyl, 4-octylbenzyl, 3,5-dimethylbenzyl, penta methyl benzyl, 2-, 3-, 4-, 5-, 6-,7- and 8-methylnaphth-1-yimethyl, 1-, 3-, 4-, 5-, 6-, 7- and 8-methylnaphth-2-ylmetriyl; benzyl residues and naphthylmethyl residues which are substituted in the aryl moiety by one or more (C1-C8>alkoxy residues, in particular (C1-CO-alkoxy residues, for example 4-methoxybenzyI, 4-neopentyloxybenzyl, 3,5-dimethoxybenzyl, 2,3,4-trimethoxy benzyl; 3,4-methyfenedioxybenzyl; trifluoromethoxybenzyl residues; nitrobenzyl residues, for example 2-, 3- and 4-nitrobenzyl; halobenzyl residues, for example, 2-, 3- and 4-chloro- and 2-, 3- and 4-fluorobenzyl, 3,4-dichlorobenzyl and pentafiuorobenzyl; trifluoromethy!benzyl residues, for example 3- and 4-triftuoromethylbenzyi and 3,5-bistrifiuoromethy I benzyl. However, substituted arylalkyl residues can also contain substituents which are different from each other. In general; preference is given to compounds of the formula I which do not contain more than two nitro groups in the molecule.
The above explanations with regard to the monovalent aryl residues apply, in a corresponding manner, to divalent arylene residues, that is divalent residues which are derived from aromatic compounds. Arylene residues can be linked via any desired positions. An example of arylene residues are phenylene residues which include 1,4-phenylsne, 1,3-phenyiene and 1,2-p'henylene.
Phenylenealkyi is, for example, phenyl en emethyl (-C6HrCH2-) or phenyieneethyl (for example -C6H4-CH2-CH2-). Alkylenephenyl is, for example, methylenephenyl (-CH2-C6H4-). Phenylenealkenyl is, for example, phenyleneethenyi or phenyienepropenyl.
Heteroaryl represents a residue of a monocyclic or polycyciic aromatic system which

iias from 5 to 14 ring members and which contains 1,2,3,4 or 5 heteroatoms as ring members. Examples of ring heteroatoms are nitrogen, oxygen and sulfur. When several heteroatoms are present, they can be identical or different Heteroaryl residues can be unsubstituted or monosubstituted or polysubstituted, for example--substituted once, twice or three times by identical or different substituenis from the series {C1-Ca)-alkyl, in particular (C1-C4>alkyl; (C1-CaJ-afkoxy, in particular (C1-C4>-atkoxy; {C1-Cs)-alkoxy, in particular (C1-Ca)-alkoxy which is substituted by one or more, for example 1, 2, 3, 4 or 5, fluorine atoms; halogen; nitro; amino; trifluoromethyl; hydroxy!; hydroxy-(C1-C4>-a!kyl such as hydroxymethyi or 1 -hydroxyethyl or 2-hydroxyethyl; methyienedioxy; dimethyl methylenedioxy; ethyienedioxy; formyi; acetyl; cyano; hydroxycarbonyi; aminocarbonyl; (C1-C4)-aikoxycarbonyl; phenyl; phenoxy; benzyl; benzyloxy; and tetrazolyl. Heteroaryi preferably represents a monocyclic or bicydic aromatic residue which contains 1,2,3 or4, in particular 1, 2 or 3, identical or different ring heteroatoms from the series nitrogen, oxygen and sulfur and which can be substituted by 1, 2, 3 or 4, in particular 1, 2 or 3, identical or different substituents from the series (C1-C6)-aIkyi, (C1-C6)-alkoxy, fluorine, chlorine, nitro, amino, trifluoromethyl, hydroxy!, hydroxy-(C1-C4)-alkyl, {C1-C4)-alkoxycarbony!t phenyl, phenoxy, benzyloxy, and benzyl. Particularly preferably, heteroaryl represents a monocyclic or bicydic aromatic residue having from 5 to 10 ring merhbers, and in particular represents a 5-membered to 6-membered monocyclic aromatic residue which contains 1,2 or 3, in particular 1 or 2, identical or different ring heteroatoms from the series nitrogen, oxygen and sulfur and which can be substituted by 1 or 2 identical or different substituents from the series {C1-CO-alkyl, (C1-Ci)-alkoxy, phenyl, phenoxy, benzyloxy, and benzyl.
Heterocycles which represent monocyclic or bicydic 5-membered to 12-membered heterocyclic rings can be aromatic or partially saturated or completely saturated. They can be unsubstituted or substituted, at one or more carbon atoms or at one or more nitrogen atoms, by identical or different substituents as specified forthe residue heteroaryl. In particular, the heterocyclic ring can be monosubstituted or polysubstituted, for example substituted once, twice, three times or four times, on carbon atoms by identical or different residues from the series (C1-C3>alkyi, for

example (C1-d)-alkyl, (C1-CaJ-alkoxy, for example (C1-d}-alkoxy such as methoxy, phenyI-(C1-d}-alkoxy, for example benzyloxy, hydroxy!, oxo, halogen, artro, amino and trifluoromethyf, and/or ring nitrogen atoms in heterocyclic rings as well as in heteroaryl residues can be substituted by (C1-Ca)-alkyl, for example (C1-C4)-aIkyl such as methyl or ethyl, or by optionally substituted phenyl or phenyl-fCH^O-aikyi such as, for example benzyl.
On the one hand, the group Het encompasses aromatic heterocycles and consequently also the groups representing heteroaryl insofar as these groups come within the definition of Het with regard to the number of the ring members and heteroatoms. On the other hand, Het additionally also encompasses non-aromatic heterocycles which are completely saturated or which contain one or more double bonds in the ring system. Het can be substituted on nitrogen atoms and/or carbon atoms by one or more, for example 1, 2, 3 or 4, identical or different substituents, for example by (C1-d)-aJkyI, in particular (C1-C1--alky!, (C3-d2)-cycloalkyl, (Qrdz}-cycioalkyl-{C1-C8)-alkyl, optionally substituted (C6-d^aryl, (Cs-d4)-aryl-{C1-Cg)-alkyI which is optionally substituted in the aryl residue, heteroaryl, heteroaryl-(C1-CB)~alkyl, (C1-Csj-alkoxy, in particular (C1-C4)-alkoxy, optionally substituted phenoxy, benzyloxy, halogen, nitro, amino, (C1-Cs)-a!kylamino, di-((C1-Ca)-alkyl)amino, trifluoromethyl, hydroxy!, methylenedioxy, dimethylmethylenedioxy, ethylenedioxy, cyano, hydroxycarbonyl, aminocarbonyl, (C1-d)-alkoxycarbonyl and ester groups in general, acyl groups, oxo (= doubly bonded oxygen atom) and thioxo (= doubly bonded suifur atom), where alky! residues can be monositbstituted or polysubstituted by fluorine.
Examples of parent compounds of neterocycfes, from which a heteroaryl residue, a residue Het, a residue of a monocyclic orbicyclic 5-membered to 12-membered heterocyclic ring, a divalent residue of a 5-membered or 6-membered heterocycle, a heterocyclic residue representing R7, or a heterocyclic residue representing R16, can be derived are, insofar as they come within the respective definition in the particular case, pyrrole, furan, thiophene, imidazole, pyrazole, oxazoie, isoxazole, thiazoie, isothiazole, tetrazole, pyridine, pyrazine, pyrimidine, pyridazine, indole, isoindole.

The explanations with regard to the monovalent heterocyclic residues including heteroaryl residues apply in a corresponding manner to divalent heterocyclic residues, for example heteroarylene residues (= divalent residues which are derived from heteroaromatic compounds).
Heterocyclic residues which represent the residue R7 can be unsubstituted or monosubstituted or polysubstituted, for example substituted once, twice, three times, four times or five times, on the. carbon atoms and/or on additional ring nitroge.n atorns. by identical or different subst'rtuents.

The acyclic substituents can contain 2, 3,4, 5, 6, 7 or 8 carbon atoms, and, in the case of a saturated alky! substituent, 1 carbon atom as well. In the case of the alkenyl substituents and alkynyl substituents, the double bond or triple bond can be located in any desired position and, in the case of the double bond, have the cis configuration or the trans configuration. As explained above, these alky! residues, aikeny! residues and alkynyl residues can be straight-chain or branched.

The residue of an amino acid, imino acid, azaamino acid, dipeptide, tripeptide or tetrapeptide representing R6 is obtained, as is customary in peptide chemistry, from the corresponding amino acid, imino acid, azaamino acid, dipeptide, tripeptide or tetrapeptide by formally removing a hydrogen atom from an amino group, for example the N-terminai amino group, or from the imino group. This group is then linked via the resulting free bond on the amino group or the imino group, by means of an amide bond, in the manner of a peptide, to the CO group in the R6-CO group.
The natural and unnatural amino acids can be present in all the stereochemical forms, for example in the D form or the L form or in the form of a mixture of stereoisomers, for example in the form of a racemate. Preferred amino acids are a-amino acids and J3-amino acids, with a-amino acids being particularly preferred. Suitable amino acids which may be mentioned, by way of example, are (cf. Houben-Weyi, Methoden der organischen Chemie [Methods of organic chemistry]. Volumes 15/1 and 15/2, Georg Thieme Verlag, Stuttgart, 1974):

When R6 represents the residue of a natural or unnatural a-amino acid, this residue can then, for example, correspond to the formula -N(R)-CH(SC}-CO-AG, in which CO-AG represents the acid group of the amino acid or a derivative thereof, for example an ester group, an amide group or a group containing a peptide residue, and SC represents the side chain of the a-amino acid, that is, for example, represents a substituent which is present in the a-position in one of the above-listed a-amino acids. Examples 6f side chains are alkyl residues, for example the methyl group in alanine or the isopropyl group in valine, the benzyl residue in phenylalanine, the phenyl residue in phenyiglycine, the 4-aminobutyi residue in lysine or the hydroxycarbonylmethyl group in aspartic acid. As well as on the basis of structural features, the side chains, and thus the underling amino acids, can also be grouped on the basis, far example, of their physicochemicai properties. For example, lipophilic side chains can be distinguished from hydrophilic side chains which latter contain polar groups, and the side chains and the amino acids be grouped accordingly. Examples of lipophilic side chains which can be present in amino acids representing R5 are alkyl residues, aryiaikyl residues and aryl residues. The same applies, in a corresponding manner, to amino acids which are part of a dipeptide, tripeptide or tetrapeptide residue representing R6.
Azaamino acids are natural or unnatural amino acids in which a CH unit has been replaced with a nitrogen atom such as is, for example, in a-amino acids the replacement of the central building block

Functional groups in the residues of amino acids, imino acids, azaamino acids, dipeptides, tripeptides and tetrapeptides, and aiso in other parts of the compounds of formula I, can be present in protected form. Suitable protecting groups, such as urethane protecting groups, carboxyl protecting groups and side chain protecting-groups, are described in Hubbuch, Kontakte (Merck) 1979, No. 3, pages 14 to 23, and in Bullesbach, Kontakte (Merck) 1960, No. 1, pages 23 to 35. The following may be mentioned, in particular: Aloe, Pyoc, Fmoc, Tcboc, Z, Boc, Ddz, Bpoc, Adoc, Msc, Mac, 2(N02), Z(Halr,), Bobz, Iboc, Adpoc, Mboc, Acm, tert-Butyl, OBzI, ONbzl, OMbzl.Bzl, Mob, Pic.Trt.
Physiologically tolerated salts of the compounds of the formula I are, in particular, pharmaceutical^ utilizable salts or nontoxic salts. Compounds of the formula I which contain acid groups such as carboxylic acid groups can, for example, be present as alkali metal salts or alkaline earth metal salts, such as sodium salts, potassium salts, magnesium salts and calcium salts, or as ammonium salts, such.as salts with physiologically tolerated quaternary ammonium ions and acid addition salts with ammonia and physiologically tolerated organic amines, such as methylamine, ethylamine, tri ethyl a mine, 2-hydroxyetbylamine, tris(2-hydroxyethy!)amine, a,a,a-tris(hydroxymethyl)methylamine (tromethamine) or amino acids, in particular basic amino acids, Salts composed of an acid compound of the formula I and an organic amine can contain the two components in the ratio 1:1 orapprox. 1:1 or else in another ratio, for example in a ratio of from approx. 1:0.5 to approx. 1:4 (1 molecule of the formula I per 0.5 to 4 molecules of the amine), in particular in a ratio of from approx. 1:0.5 to approx. 1:2(1 molecuie of the formula ! per 0.5 to 2 molecules of the amine).
Compounds of formula I, which contain basic groups, for example an amino group, amidino group, guanidino group or pyridyl group, can, for example, be present as

salts with inorganic acids, such as hydrochloric acid, sulfuric acid or phosphoric acid, or with organic carboxylic acids or sulfonic acids, such as acetic acid, citric acid, benzoic acid, maleic acid, fumaric acid, tartaric acid, methanesulfonic acid or p-toluenesulfonic acid. Compounds which contain both acid groups and basic groups can also be present in the form of inner sails, zwitterions or betaines, which are likewise encompassed by the present invention.
Salts can be obtained from compounds of the formula i using customary methods which are known to skilled persons, for example by combining a compound of the formula I with an organic or inorganic acid or base in a solvent or diluent, or just so from other salts by means of anion exchange or cation exchange. The present invention also encompasses salts of compounds of the formula I which are not directly suitable for use as pharmaceuticals on account of lower physiological tolerability but which can be used, for example, as intermediates for chemical reactions or for preparing physiologically tolerated salts.
Compounds of the formula I can be present in stereoisomers forms. When the compounds of the formula I contain one or more centers of asymmetry, the S configuration or the R configuration, or an RS mixture, can be present, independent of each other, at each of the asymmetric centers. The invention includes all the possible stereoisomers of the compounds of the formula I, for example enantiomers and diastereomers, and mixtures of two or more stereoisomeric forms, for example mixtures of enantiomers and/or diastereomers, in all ratios. The invention thus relates to enantiomers in enantiomericalfy pure form or substantially enantiomericaliy pure form, the ievorotatory antipode as well as the dextrorotatory antipode, and to enantiomers in the form of racemates and in the form of mixtures of the two enantiomers in any ratio. The invention likewise relates to diastereomers in diastereomerically pure form or substantially diastereomerically pure form and in the form of mixtures in any ratio. When a cis/trans isomerism is present, the invention relates both to the cis form and to the trans form and to mixtures of these forms in all ratios. If desired, individual stereoisomers can be prepared by using stereochemicaiiy homogeneous starting substances in the synthesis, by means of stereoselective

synthesis, or by separation of a mixture using customary methods, for example by means of chromatography or crystallization including chromatography on chiral phases in the case of a separation of enantiomers. Where appropriate, a derivatization can take place before stereoisomers are separated. A stereoisomer^ mixture can be separated at the level of the compounds of the formula I or at the level of a starting substance or of an intermediate during the course of the synthesis.
The compounds of the formula 1 according to the invention can contain mobile hydrogen atoms, that is be present in various tautomeric forms. The present invention relates to all the tautomers of the compounds of the formula I. The present invention furthermore encompasses derivatives of compounds of the formula I, for example solvates, such as hydrates and adducts with alcohols, esters, prodrugs and other physiologically tolerated derivatives of compounds of the formula I, and also active metabolites of compounds of the formula i. The invention relates, in particular, to prodrugs of the compounds of the formula I which are not necessarily pharmacologically active in vitro but which are converted in vivo, under physiological conditions, into active compounds of the formula \. The skilled person is familiar with suitable prodrugs for the compounds of the formula !, that is chemically modified derivatives of the compounds of the formula I possessing properties which have been improved in a desired manner. Further details with regard to prodrugs can be found, for example, in Fleisher et al„ Advanced Drug Delivery Reviews 19 (1996) 115-130; Design of Prodrugs, H. Bundgaard, Ed., Elsevier, 1985; or H. Bundgaard, Drugs of the Future 16 (1991) 443. Prodrugs which are especially suitable for the compounds of the formula l are ester prodrugs of carboxylic acid groups, amide prodrugs of carboxylic acid groups and alcohol prodrugs of carboxylic acid groups as well as acyl prodrugs and carbamate prodrugs of acyiatable nitrogen-containing groups such as amino groups, amidino groups and guanidino groups, in the acyl prodrugs or carbamate prodrugs, a hydrogen atom which is located on a nitrogen atom is replaced with an acyl group or carbamate group. Suitable acyl groups and carbamate groups for the acyl prodrugs and carbamate prodrugs are, for example, the groups Rp-CO and RpaO-CO, in which Rp is hydrogen, (C1-Cia)-alkyl, (C1-d2)-cycloalkyl. (c3~ Ci2)-cycioalkyl-(C1-C6)-alkyi, (C6-C1--aryl, (C6-C1-y-aryl-fC1-CaJ-alkyl, heteroaryl or

heteroaryl-(C1-Cs)-alkyl, and Rp3 has the meanings given for Rp with the exception of hydrogen. Thus, for example, the compounds of the formula I in which the group E ia hydroxymethyl, alkoxymethyi or formyi, and which exhibit a VLA-4 antagonism in vivo, are prodrugs of the compounds of the formula i in which the group E is hydroxycarbonyl. Examples of ester prodrugs and amide prodrugs which may be mentioned are (C-i-C1--alkyl esters such as methyl esters, ethyl esters, n-propyl esters, isopropyl esters, n-butyl esters and isobutyl esters, substituted alky) esters such as hydroxyalkyl esters, acyloxyalkyi esters, aminoalkyl esters, acyiaminoalkyl esters and dialkylaminoalkyl esters, unsubstituted amides and N-(C1-C4)-alkyfamides, such as methylamides or ethylamides.

Residues which occur more than once can possess the meanings independently of each other and can be identical or different.

In general, preference is given to compounds of the formula I which are present in uniform configuration, or in essentially uniform configuration, at one or more chiral centers, for example at the carbon atom carrying the residues R^ and R^ and/or at the center W in the imidazolidine ring in the formula I provided that they are appropriately substituted for being chiral. That Is, preference is gjven to compounds which are present uniformly, or essentially uniformly, in the R configuration or the S configuration at one or more chlrai centers, but are not present as an RS mixture. However, the individual chiral centers in these compounds of the formula I can exhibit the R configuration or the S configuration independently of each other and can have the same or different configurations.
The compounds of formula I can, for example, be prepared by reductive amination of a compound of the formula 11


where in the formulae H and ti! the groups B, E, W, Y, R, R^, R^ and R^'^ and e and h are defined as specified above, or else functionai groups can be present in these groups in protected form or in the form of precursors, and where G is the aldehyde group CHO. When compounds of the formula i are to be prepared in which a group, for example the group R^, is a carboxylic acid derivative group or contains such a group, the respective group, for example R^, in the compounds of formula 111 can. initially be a hydroxycarbonyl group which is present in protected'form or contain such a group, with the desired final group R^ only subsequently being synthesized in one or more additional steps. Precursors of functionai groups are groups which can be converted into the desired functional group using the customary synthesis methods which are known to the skilled person. For example, a nitro group can be converted into an amino group by reduction, for example by catalytic hydrogenation, and can be regarded as being a precursor of an amino group or of a group which can be obtained from the amino group by means of further reactions. A cyano group, which can be converted by reduction into an an^inomethi^ group, or by hydrolysis into a carboxamide group or a carboxylic acid group, can be regarded as being a precursor of these groups. An alcohol group which can be oxidized to give an sfdehyde group or a ketone group can be regarded as being a precursor of these groups. However, a precursor of a group can also be a group from which a rF^ifltmoU,

•o-ge part of the target molecule can be synthesized in several reaction steps which are can'ted out subsequently. Examples of protecting groups which are attached to the nnoiecule before canying out a reaction or a reaction sequence, and which are subsequently cleaved off again, are mentioned above.
The amino compounds of the fomiuia \\\ are commercially available or can be synthesized by well-l The reductive aminations of compounds of the formula II with compounds of the formula IN can be carried out under standard conditions which are well itnown to the skilled person (see, for example, J. Martinez et a!., J. Med. Chem. 1985, 28,1874; L,

the corresponding N-methoxy-N-methylamides (Weinreb amides) which are subsequently reduced to the aldehydes, for example using lithium aluminum hydride {see, for example, J.-A. Fehrentz, B. Castro, Synthesis 1983, 676). A has already been stated in a general manner, in these reactions, too. It can be advantageous or necessary for functional groups to be protected with protecting groups which are then eliminated in a suitable manner after the reaction, or for functional groups to be present in the form of precursors.
Compounds of the formula IV, in which W represents R^-A-C(R^^) and Y represents a carbonyl group, can be prepared, for example, by initially reacting compounds of the fonnula V



in which R', R""^, A and B are defined as specified above, and G' represents {C1-C1-ValkoxycarbonyJ or hydroxycarbony!, can then be obtained by, for example, initially reacting the compounds of the formula VI with an ali^ylating reagent which introduces the residue -B-G' into the molecule. The subsequent reaction of compounds of the fonnula VII with a reagent of the fomnula R^°-LG, in which R^° has the abovementioned meanings and LG represents a nucleophilicaliy substitutabie leaving group, for example halogen, such as chlorine or bromine, sulfonyloxy, such as tosytoxy, methylsulfonyloxy or trifluoromethyisulfonyloxy, (CrCft)-alKoxy, optionally substituted phenoxy or a heterocyclic leaving group such as imidazolyl, then leads to the corresponding compounds of the formula IV in which G' represents (CrC6)-afkoxycarbonyl or hydroxycarbonyl and W represents R'-A-C(R'^).
In a general manner, it may also be advantageous, depending on the meanings of the residue R^" and of other residues, not to use the reagent R^-LG to introduce the final residue R^" directly into the molecule but, instead, to synthesize the residue R^° on the imidazolidine ring after a precursor of the group R^ has been connected to the imidazolidine ring. This can be done, for example, at the stage of a compound of the formula VII or ai the stage of another intermediate in the synthesis. By way of example, this approach is described below using compounds In which R^° represents the urea group R^^{R)N-CO-N(R>R^\ Compounds of the formula iV in which R^ represents R^^(R)N-CO-N(R)-R^^ can be prepared in accordance with mis approach by, for example, initially reacting a compound hf the formula Vl! with a reagent of the formula PG-N(R)-R^'-LG, in which LG represents a nucleophilicaliy substitutabie leaving group as explained above, to give a compound of the formula Vlil


in which PG represents an amino protecting group, for example tert-butoxycarbonyl or benzyloxycarbonyt, and in which otherwise the meanings given above for ttie compounds of the formula Vl) and 1 apply. After the protecting group PG has been removed, compounds of the fonnula IV, in which R^° represents R^^NH-CO-N(R)-R^^, are then obtained by reacting the resulting amino group -NHR with an isocyanate of the formula R^^-N=C=0. Compounds of the fonnula IV in which R^° represents R^^(R)N-CO-N(R)-R^' are obtained by employing in the reaction, for example, a cartiamoyl chloride of the formula R^(R)N-C0-C1. in a corresponding manner the ' analogous thiourea derivatives can be obtained using isothiocyanates and thiocarbamoyl chlorides, {Thio)Acylamines, suifonylamines, sulfinylamines and sulfamides can be obtained by reacting the amino group with reactive carboxylic acid derivatives, thiocarboxylic acid derivatives, sulfonic acad derivatives, sulfinic acid derivatives and sulfamoyl chlorides. Just like compounds of the formula VIII, it is also possible to prepare, and employ In subsequent reaction steps, compounds in which in the formula VIII the group PG-N(R)- has been replaced with a group which constitutes a precursor of an amino group and which is then converted into an amino group in a subsequent reaction step. For example, a compound of the formula VII can initially be reacted with a nitro compound of the fomiula 02N-R^'-LG or a cyano compound of the formula NC'R^'-LG to give a compound corresponding to the compound of the formula VIII, in which the nitro,group or the cyano group can be converted,,for. example by catalytic,.hydrQgenation,.iniQ.an.am!nQ group which amino group can then be converted into the desired target group, for example using an isocyanate of the formula R^^-N=C=0 to give a urea derivative in which R^° represents R^^NH-CO-NH-R^\ or else using other compounds. This approach can be

used to synthesize a large number of other compounds of the formula [, with the reactions to be performed always being standard methods which are familiar to the skilled person.
In general, the individual steps performed in preparing the compounds of the formula I can be carried out using methods known per se which are familiar to the sidlied person, or in analogy to such methods. As has already been explained, depending on the particular case, in can be appropriate in all steps involved in Uie synthesis of the compounds of the formula I to temporarily block functional groups which might be able to lead to side reactions or undesirable reactions, using a protecting group strategy which is adapted to the synthetic route, as is known to the skilled person. The above-explained approach of not introducing functional groups directly into the molecule in their final form but, instead, initially introducing precursors into the molecule and then synthesizing the final functional group at the stage of an intermediate can, as has already been mentioned, also be applied correspondingly for other parts of the molecule of the formula I, for example for the group R' or the group R^.


„, ^/h\ch R\ A, L, m1 and m2 are defined as specified above, in a Bucherer reaction, as described above for the preparation of the compounds of the formula VI, to give compounds of the formula X


this structural element can, for e>cample, be introduced by condensing the corresponding aldehyde or the corresponding ketone, in analogy with l


in which W is R^-A-C{R^^) and Z, B. Q and R^° are defined as specified above. With catalysis by a base, the cycilzation can be achieved, for example, by treatment with sodium hydride in an inert aprotic solvent such as dimethylformamide. A compound of the formula I in which W is R'-A-C(R'^) can then be obtained from the compound of the formula XV by, for example, hydrolyzing the group CO-Q to give the carboxylic acfd COOH, converting this into the Weinreb amide, reducing the Weinreb amide to the corresponding aidehyde and subsequently perfomiing a reductive amination using a compound of the formula ill, as described above for the reductive amination of the compounds of the formula (I, In this synthesis method, as well, it can be expedient for functional groups to be present in protected fomn or in the form of precursors.
Compounds of the formula I in which Y is a carbonyl group can also be prepared by first coupling a compound of the formula XVI,


in which R\ R""^, A, B, PG and COQ' have the abovementioned meanings. The protecting group PG in the compound of the formula XVlll can then be selectively eliminated from the amino group, for example by means of hydrogenating in the case of a benzyloxycarbonyl group, and a ring closure can be performed, by Introducing a carbonyl group, to give a compound of the formula XIX,


in which R\ R^^, A, B and COQ' have the above-mentioned meanings. Phosgene or a phosgene equivalent, such as diphosgene ortriphosgene. can be used, for eismple, for introducing the carbony! group. As an intermediate step in the conversion of the compound ofthe formula XVIII into the compound of the formula XIX, for example, an isocyanate can appear or can be prepared detrberately. The conversion of the compound of the formula XVlll into the compound of the formula XIX can take place in one or more steps. For example, the cydization which is effected after the carbonyl group has been introduced can be carried out, like the above-described cyciizations, separately in the presence of a base such as sodium hydride. Compounds of the formula XVlll in which PG is an alkoxycarbonyl group, an aryialkoxycarbonyl group or an aryloxycarbonyi group can also be converted directly into compounds of the formula XIX without a synthetic building block, such as phosgene, being used for introducing the carbonyl group. If, for example, compounds of the fomiula XVlll in which PG is benzyloxycarbonyl are treated with a base, such as sodium hydride or sodium carbonate, it is possible to obtain the compounds of the fonnula VII directly.
Compounds of formula IV in which G' is a hydroxycarbonyl group COOH can advantageously be prepared from compounds of the formula XX,


m which G"" is a hydroxycarbonyl group and W and Y are defined as specified above, by reacting the compounds of the formula XX in the presence of excess base, for example in the presence of an excess of n-butyilrthium, with an alitylating reagent, for example with an aii Compounds of the fonnula) can furthemiore be prepared by reducing the amide group C(=0)-NR in compounds of the formula XXI,

in which B, E, W, Y, R, R^, R^ R^°, e and h have the meanings given for the compounds of the formulae II and Hi, to the amino group CH2-NR under conditions known to the skilled person, for example using the borane-dimethyl sulfide complex. The compounds of formula XXI can be prepared, using standard methods for forming amide bonds, from compounds of the formula lil,ori:he analogous compounds which contain an RNH group in place of the terminal H2N group in the formula III, and compounds of the formula fV.
The following reagents, for example, can be usfed to obtain a guanidino group containedih the residue R^ from afi amino group, which amino group can in Ujm be obtained, for example, from a nitro group or a cyano gnDup by reduction:

Arfiitiines can be prepared from the corresponding cyano compounds by tlis addition of alcohols, for example methanol or ethanol, in acidic anhydrous,medium, for example dioxane, methanol or ethanol, and subsequent aminolysis, for example treatment with ammonia in alcohols such as Isopropanol, mettianol or ethanol (G. Wagner, P. Richter and Oh. Garbe, Pharmazie 2S (1974), 12-55), Another method of preparing amidines is the addition of hydrogen sulfide to the cyano group, followed by a methylation of the resulting thioarriide and subsequent reaction with ammonia (DDR patent No. 235 866). Furthermore, hydroxylamine can be added to the cyano group, to give N-hydroxyamidines which, if desired, can likewise be converted Into the amidines, for example by means of hydrogenation.
Compounds of the formula i in which vv is i'Ji-3)2C can be. prepared, for example, by converting a compound of the fonnula Vll, in which R"* is trifiuoromethyl, A is a direct linkage and R^^ is trifiuoromethyl, as explained above for the compounds of the formula Vll. into a compound of the fonnula IV in which G' is (CrC1-j-alkoxycarbonyl

or hydroxycarbonyl, from which the corresponding compound of the formula tl, in which G is CHO, can be obtained as described above. Compounds of the formula VI!, in which the residues R'-A~ and R'^ are trifiuoramethyl and G' is an ester group such as (C1-C6)-al!^oxycarbonyi, that is has the meaning of G", can advantageously be prepared by reacting an isonitrile of the formuia XXII with the 2-tert-butoxy-4,4-bis(trifiuoromethyl)-1,3-oxazabuta-1,3-d)ene of the formula XXlll to give a compound ofthefomnulaXXIV

subsequently treating the 2-tert-butaxycarbonyiamino-2-hydroxy-1,1,1,3,3,3-hexafluoropropane, which is initially obtained, with trifiuoroacetic anhydride in the presence of a base, such as quinoline.
Standard methods can be used to convert compounds of the fomiula I, in which E is, for example, hydroxycarbonyf or hydroxymethyl, into compounds of Ihe formula 1 in which E has other meanings, or into other prodrugs or derivatives of the compounds of the formula 1. Thus, in order to prepare esters, for example, the compounds of the formula i in which E is hydroxycarfaonyl can be esterified with alcohols, for example in the presence of a condensing reagent such as carbonytdiimidazole or a carbodiimide such as DCC {dicyciohexyicarbodiimide), or the compounds of the formula I in which E is hydroxycarbonyl can be alkylated with alkyl halides such as aikyi chlorides or alkyi brcimides, for example using chloroalkanoic acid amides to give compounds of the formula I in which E is R^R^N-CO-ali Furthermore, with regard to the preparation of the compounds of the formula I, the entire contents of WO-A-95/14008, of EP-A-796855 and of the applications corresponding to it, of EP-A-918059 and of ths applicatons corresponding to it, and

of WO-A-96/33976 are hereby incorporated by reference, in particular, reference is made to the disclosure in WO-A-96/33976 with regard to the preparation of the compounds of the fomnuiae VI and V(l which is an integral part of the present disclosure.
The compounds of formula I are valuable pharmaceutical active compounds which are suitable, for example, for treating inflammatory diseases, allergic diseases or asthma. According to the invention, the compounds of formula I and their physiologically tolerated salts and derivatives can be administered as pharmaceuticals to animals, preferably to mammals, and in particular to humans, for the treatment of disease states. Treatment is understood as meaning, in a general manner, both therapy including aliaeviation and cure of disease symptoms, and prophylaxis or prevention of disease symptoms, such as, for example, the prevention of the appearance of allergic or asthmatic disease symptoms or the prevention of myocardial infarction or of myocardial reinfarction In relevant patients. The disease symptoms can be acute or chronic. The compounds of formula i, and their salts and derivatives, can be administered on their own, in mixtures with each other or in the ■form of pharmaceutical preparations which permit enteral or parenteral use and which comprise, as the active constituent, an effective dose of,at least one compound of the formula I and/or its physiologically tolerated salts and/or derivatives and a pharmaoeutically acceptable carrier.

Ttie present invention furthermore relates to pharmaceutical preparations (or pharmaceutica! compositions) which comprise an effective dose of at least one compound of the formula I and/or its physiologically tolerated salts and/or derivatives and a pharmaceuticaliy acceptable

carrier, that is one or more pharmaceutically acceptable vehicles and/or additives or auxiliaries.
The pharmaceuticals may be administered systemically or locally. They can be administered orally, for example, in the form of pills, tablets, film tablets, sugar-coated tablets, granules, hard and soft geiatin capsules, powders, solutions, syrups, emulsions or suspensions or in other galenical forms. However, the administration can also be effected vaginally or rectally, for example in the form of suppositories, or parenteraliy or by means of an implant, for example in the form of injection solutions or infusion solutions, microcapsules or rods, or topically or percutaneousiy, for example in the form of creams, ointments, powders, solutions, emulsions or tinctures, or in another way, for example in the form of nasal sprays or aerosol mixtures. Parenteral administration of solutions can occur, for example intravenously, intramusculariy, subcutaneously, intraarticularlyorintrasynoviaiiy, or in another manner.
The pharmaceutical preparations according to the invention are produced in a manner Icnown per se, witii ftie compound or the compounds of the fonriLila 1 and/or their physiologicaliy tolerated salts and/or derivatives being mixed with pharmaceutically inert inorganic atid/or organic vehicles and/or additives and brought into a suitable dosage form and administration form. For example, lactose, corn starch or derivatives thereof, talc, stearic acid or its salts, polyethylene glycols, etc. can be used for producing pills, tablets, sugar-coated tablets and hard gelatin capsules, while fats, waxes, semisolid and liquid polyols, polyetiiylene glycols, natural or hardened oils, etc. can, for example, be used for producing soft gelatin capsules and suppositories.

The pharmaceutical preparations normally comprise from about 0.5 to about 90% by weight of the compounds of the fonnula 1 and/or their physiologically tolerated salts and derivatives. The quantity of active compound of the

formula I and/or its physiologicaiiy tolerated salts and derivatives in the pharmaceutical preparations is nomnally from about 0,2 to about 1 ODD mg, preferably from about 1 to about 500 mg. However, depending on tiie nature of the pharmaceutical preparation, the quantity of the active compound can also be greater.
Aside from the active compounds and vehicles, the pharmaceutical preparations can also contain auxiliary substances or additives, for example fillers, disintegrants, binders, glidants, wetting agents, stabilizers, emulsifiers, preservatives, sweeteriere, dyes, flavorings, aromatizing agents, thickeners, diluents, buffering substances, solvents, solubiiizers, agents for achieving a depot effect, salts for altering the osmotic pressure, coating agents or antioxidants. They can also comprise'two or more compounds of the formula I and/or their physiologically tolerated salts and/or derivatives. Furthermore, apart from at least one compound of the formula 1 and/or its physiologically tolerated salts and derivatives, the pharmaceutical preparations can also comprise one or more additional pharmaceutical active compounds, for example compounds vitiich possess an antiinflammatory effect.
When the compounds of the formula 1 or pharmaceutical preparations comprising them are administered as aerosols, for example as nasa! aerosols or by inhalation, this can be carried out, for example, using a spray, an atomizer, a pump atomizer, an inhalation appliance, a metered inhaler or a dry powder inhaler. Pharmaceutical forms for administering the compounds of fonnuia ( as aerosols can be produced using methods which are well known to the skilled person. For their production, for example, solutions or dispersions of the compounds of the formula 1 in water, water-alcohol mixtures or suitable sodium chloride solutions can be employed, using customary additives, for example benzyl alcohol or other suitable preser/atives,
absorption improvers for increasing bioavaiiability, solubiiizers, dispersing agents,
s and others, and, where appropriate, customary propellants, for example
fluorochlorohydrcicarbons and/or fluorohydrocarbDns.
Other phamiaceutical active compounds, wiiich can be present, together with compounds of the formula I, in the pharmaceutical preparations accordina to fho

invention, but with which the compounds of the fomiuja I can also be combined In other ways within the context of a combination treatment, are in particular those active compounds which are suitable for the treatment, that is the therapy or prophylaxis, of the diseases mentioned above or below and for whose treatment the" compounds of the fomiula 1 are suitable.

When compounds of the formula I and/or their physiologically tolerated salts and/or derivatives are to be used together with one or more other active compounds in a combination treatment, this can be carried out, as has been mentioned, by all the active compounds being administered together in a single pharmaceutical preparation, for example a tablet or capsule. The present invention likevi/ise relates expressly to such pharmaceutical preparations to which all the above explanations apply correspondingly. In general, the amount of the active compounds in these pharmaceutical preparations is chosen such that an effective amount of each of the active compounds is present. However, a combination treatment can also be carried out by the active compounds being contained in two or more separate pharmaceutical preparations, which can be present in a single pack or in two or more separate packs. The compounds of the formula i and/or their physiologically tolerated salts or derivatives and the other active compounds can be administered either jointly or separately and be administered simultaneously or sequentially. The administration can also be effected in different ways; for exampie, one active compound can be administered orally and the other administered by injection, inhalation or topical application.
The compounds of the formula I have, for example, the abiSity to int^ibit celi-cell interaction processes and cell-matrix interaction processes in which interactions between VLA-4 and Jls Sigands play a role. The activity of the compounds of the formula i can be demonstrated, for example, in an assay which measures the binding of cet)s which possess the VLA-4 receptor, for example leukocytes, to ligands of this receptor, for example to VCAM-1 which can advanfageousiy also be prepared recombinantly for this purpose. Details of such an assay are described below. In

particular, the compounds of the formula 1 are abie to inhibit the adhesion and migration of leui^ocytes. for example the adhesion of leui^ocytes to endothelial oells, which adhesion, as expiained aixwe, is controlled byway of the VCAM-1/V1-A-4 adhesion mechanism. Aside from their use as antiir^ammatory agents, the compounds of the formula 1 and their physiologically tolerated salts and derivatives are therefore suitable, in a general manner, for the treatment, that is for the therapy and prophylaxis, of diseases which are based on the interaction between the VLA-4 receptor and its (igands or which can be influenced by an inhibition of this interaction, and are in particular suitable for treating diseases which, at least in part, are caused by, or associated with, an undesirable extent of ieuKocyte adhesion and/or leukocyte migration and for whose prevention, alleviation or cure the adhesion and/or migration of leukocytes is to be reduced.
The present invention therefore also relates to the compounds of the formula I and their physiologically tolerated salts and derivatives for inhibiting the adhesion and/or migration of leukocytes or for inhibiting the VLA-4 receptor, and to the use of the compounds of the formula 1 and/or their physiologically tolerated salts and deriva^ves for produdng pharmaceu^cals for this purpose, that is pharmaceuticals for treating diseases in which the ei^ent of leukocyte adhesion and/or leukocyte migration is undesirable, or for treating diseases in which Vl_A-4-depeadent adhesion processes play a role, and to the use of the compounds of the formula I and/or their physiologically tolerated salte and derivatives in treating such diseases.
The compounds of the formula I can be used as antiinflammatory agents in the case of inflammatory symptoms arising from a very wide variety of causes in order to prevent, reduce or suppress the undesirable or damaging sequelae of the inflammation. The compounds of the formula I are used, for example, for the treatment, that is the therapy or, prophylaxis, of arthritiSi.Df rheumatoid arthntis, of polyarthritis, of inflammatory bowel disease {ulcerative colitis, Crohn's disease), of systemic lupus erythematosus, of inflammatory diseases of the central nervous system, such as multiple sclerosis, or of asthma or of allergies, such as delayed-type allergies (t^^e IV allergy). The compounds are furthermore suitable for

oardioprotection, for protection against stroke and for the secondary prophylaxis of sfroke and for the treatment, that is the therapy and prophylaxis, of cardiovascular diseases, of atherosclerosis, of myocardial infarction, of myocardial reinfarction, of acute coronary syndrome, of stroke, of restenoses, of sepsis, of sepic shock, of diabetes, of damage to organ transplants, of immune diseases, of autoimmune diseases, of tumor growth or tumor metastasis in the case of various malignancies, of malaria and of other diseases in which blocking the integrin VLA-4 and/or influencing leukocyte activity appears appropriate for achieving prevention, ailevtation or cure. Preference is given to the use for the prevention of myocardial infarction or myocardial reinfarction orfor the treatment, that is forthe therapy and prevention, of atheroBcierosis, asthma or multiple sclerosis.
The dose when using the compounds of the formula I can vary within wide limits and is in each individual case to be adjusted to the individual circumstances, as is customary and tcnown to the physician. The dose depends, for example, on the nature and severity of the disease to be treated, on the condition of the patient and on the compound employed, on whether an acute or chronic disease state is being treated or whether prophylaxis is being pursued, or on whether other active compounds are being administered in addition to the compounds of the formula 1. In general, when the dose is being administered orally, a daily dose of from about 0.01 to about 100 mg/kg, preferably of about 0.1 to about 10 mg/kg (in each case mgper kg of body weight) is appropriate for achieving effective results when the dose is being administered to an adult of about 75 kg in weight. When administered intravenously, the daily dose is in general from about 0.01 to 50 mg/kg, preferably from 0.01 to 10 mg/kg of body weight. Particularly when relatively large quantities are being administered, the daily dose can be divided up into several, for example 2,3, or 4, partial administrations. Where appropriate, depending on the individual response, it may be necessary to deviate in an upward or downward direction from the specified daily dose.
Aside from being used as pharmaceutical active compounds in human medicine and veterinary medicine, the compounds of the formula i and their salts and derivatives

which are suitable for the desired us can additionally be used for diagnostic purposes, for example in in vitro diagnoses of cell samples or tissue samples and as auxiliaries or scientific tools in biochemical investigations in which the blocking of VLA-4 or influencing of celi-cell interactions or cell-matrix interactions is desired. The compounds of the fomiula I and their salts can also be used as intermediates for preparing other compounds, in particular other pharmaceutical active compounds, which can be obtained from compounds of the formula I for example by modilyifig or introducing residues or functional groups, for example by esterification, reduction, oxidation or other transformations of functional groups.

1a) 4-(3-{2-Methylphenyl)ure)do)-3'methoxyben2yl alcohol
15 g (81.6 mmol) of 3-methoxy-4-n(trobenzyl alcohol were hydrogenated in 500 m! of methyl tert-butyl ether over 1.3 g of pafladium/charcoal (10%; 50% water) while cooling with ice. After the uptake of hydrogen had ceased, the catalyst was filtered off and 10.14mr (8r,8 mmol}' ofZ-meth'ylphenyl isocyanate were added to the filtrate within 30 min while stirring. The reaction mixture was left to stand overnight and the precipitated solid was filtered off with suction and washed with methyl tert-butyl ether. Yield: 20.5 g (88%).

1b} 4-{3-(2-M ethyl phenyI)ureido)-3-methoxybenzyl chloride
7.65 ml (104.8 mmol) of thionyl chloride were added dropwise, while cooling with ice, to a suspension of 15 g (52.4 mmol) of the compound of example la) in 300 ml of ■ dichloromethane. The reaction mixture was stirred at room temperature for 3 h, ieft to stand overnight and then poured onto 1 000 ml of heptane. The heptane was decanted off from the oil which had separated; the residue was then slurried once again with heptane and the heptane was decanted off. This procedure was repeated a further two times. The residue was then dissolved in dichloromethane and this solution was poured into 800 ml of ice-coid dilsopropyl ether. This mixture was stin-ed for 2 h while cooiing with ice, the product was filtered off with suction and washed with diisopropyl ether. 12 g (75%) of the title compound were obtained after drying over phosphorus pentoxide.
1c) Benzyl (S)-2-amino-3-cyclopropylpropionate
1N Sodium hydroxide solution was added, at CC, to a suspension of 10 g (77.5 mmo!) of (S}-2-amino-3-cyclopropylpropiQnic acid in 160 mi of dioxane until a pH of 8 to 9 was reached. 16.9 g (77.5 mmol) of di-terf-bufyl dicarbonate were then added, the ice bath was removed, and the pH was kept at 8 to 9 by the further addition of 1N sodium hydroxide solution.

The assay described below which is specific for the interaction between VCAM-1 and VLA-4, is used as the method for testing the activity of the connpounds of the formula I on this Interaction. The cellular binding partners, that is the VLA-4 Integrins, are supplied in their natural fonn as surface molecules on human U937 cells {ATCC CRL 1593) which belong to the leui^ocyte group. The specific binding partners employed are recombinantly prepared soluble fusion proteins which consist of the extracytoplasmic domain of human VCAM-1 and the constant region of a iiuman immunoglobulin of the lgG1 subclass.
Assay for measuring the adhesion of U937 cells {ATCC CRL 1593) to hVCAl\fl-1(1-3)-lgG
1. Preparation of human VCAM-1 (1 -3)-lgG and human CD4-!gG
A gene construct for expressing the extracellular domain of human VCAM-1 linked to the gene sequence forthe heavy chain of human immunoglobulin IgGI (hinge, CH2 and CHS regions) (from Dr. Brian Seed, Massachusetts General Hospital, Boston, USA; cf. Damle and Aruffo, Proc. Natl. Acad. Sci. USA 1991, 88, 6403) was employed. The soluble fusion protein hVCAM-1(1-3)-lgG contained the three aminoterminal extracellular immunoglobulin-Iike domains of human VCAM-1 (Damle and Aojffo, Proc. Natl. Acad. Sci. USA 1991, 88, 6403), CD4-lgG (ZettlmeissI et at., DNA and C1-ll Biology 1990, 9, 247) was used as the fusion protein for negative controls. The recombinant proteins were expressed as soluble proteins following the DEABdextran-medialed transfection of DNA into COS cells (ATCC CRL1651) using standard procedures (Ausubel et al., Current protocols in molecular biology, John Wiley S Sons, inc., 1994).
2. Assay for measuring the adhesion of U937 cells to hVCAM-1(1-3)-lgG
2.1 96-welI microtiter test plates (Nunc Maxisorb) containing 100 pl/well of a goat anti-human igG antibody soiution (10 pg/mi in 50 mM Tris, pH 9.5) were incubated at

room temperature for 1 hour. Alter the antibody solution had been removed, the piafes were washed once with PBS.
2.2 150 pl/weli of a blocking buffer {1% BSA in PBS) were incubated on the plates at room temperature for 0.5 hour. After the blocking buffer had been removed, the plates were washed once with PBS.
2.3 100 pi/well of a cell culture supernatant from transfected COS cells were incubated on the plates at room temperature for 1.5 hours. The COS cells were transfected with a plasmid which encodes the three N-terminal Immunoglobulln-like domains of VCAM-1 coupled to the Fc moiety of human igGi (hVCAM-1(1-3)-lgG), The content of hVCAM-1(1-3)-lgG was approx. 0.5-1 yg/mi. After the culture supernatant had been removed, the plates were washed once with PBS.
2.4 The plates were incubated with 100 pl/well of Fc receptor blocking buffer (1 mg/mly-gtobulin, lOOmMNaC!, 100 pM MgCt2, lOOpMMnCb, lOOpMCaCb, 1 mg/m! BSA in 50 mM HEPES, pH 7.5) at room temperature for 20 minutes. After the Fc receptor blocking buffer bad been removed, the plates were washed once with PBS.
2.5 20 Vil of binding buffer (100 mM NaCl, 100 ^iM MgCla, 100 \xM MnCla, 100 \iU CaCb, 1 mg/mi BSA in 50 mM HEPES, pH 7.5) were introduced, the substances to be tested were added in 10 [jl of binding buffer, and the plates were incubated for 20 minutes. Antibodies directed against VCAM-1 (BBT, No. BBA6) and against VLA-4 (immunotech, No. 0764) were used as controis.
2.6 U937 ceils were incubated in Fc receptor blocking buffer for 20 minutes and then pipetted in at a concentration of 1 x 10^/ml and in a quantity of .100 pi per well (final volume: 125 pl/well).

2.7 The plates were slowly immersed, at an angle of 45°, into stop buffer (100 mM NaCI, 100 pM MgCh. 100 [iM MnCb, 100 ^JM CaC1- in 25 mM Tris, pH 7.5) and excess liquid then removed by tapping. The procedure was repeated.
2.8 50 pl/well of a dye solution (16.7 [jg/ml of Hoechst dye 33258, 4% formaldehyde, 0.5% Triton-X-100 in PBS)/well were then incubated on the piates for 15 minutes.
2.9 Excess liquid was removed from the piates by tapping and the plates were then slowly immersed, at an angle of 45°, into stop buffer (100 mM NaCI, 100 pM M9CI2,100 pM MnCb, 100 pM CaCb in 25 nM Tris, pH 7.5). The procedure was repeated. The plates were then measured, with the liquid (stop buffer) present, in a cytofluorimeter (Millipore) (sensitivity; 5, filter excitation wavelength: 360 nm, emission wavelength: 460 nm).
The intensity of the light emitted by the stained U937 cells is a measure of the number of the U937 cells which have adhered to the hVCAM-1(1-3)-lgG and thus remained on the plate, and thus is a measure of the ability of the added test substance to inhibit this adhesion. The IC50 concentration, which results in the adhesion being inhibited by 50%, was calculated from the inhibition of the adhesion observed at various concentrations of the test substance.

The pharmacological properties of the compounds of the fonnuia 1 can also be investigated in the following models.
B) Leukocyte adhesion in the rat
In the rat leukocyte adhesion model, the ability of the compounds of the formula I to influence the adhesion of leukocytes Is investigated in rat venules. The adhesion of leukocytes to the endotheiium of post-capi(fary venules is regarded as being an important step in inflammation reactions (J. M. Harlan, Blood 1985, 65, 513). A well-coordinated dynamic sequence of events, in which chemotactic cytokines and cellular adhesion molecules play an active role, takes place when leukocytes are recruited from the blood into inflan:ied regions. !t has been found that VCAM-1A/lj\-4 interactions play a crucial role in the adhesion and emigration of ieutcocytes and in the increased permeability of blood vessels to macromolecules, which are induced by various mediator substances and cytokines (D. Seiffge, Int. J. Microcirc. 1995,15, 301). In the present model, local or systemic injections of endotoxins, for example zymosan, bactenal toxins such as lipopolysaccharides (LPS), or Freund's adjuvant, are used fo elicit a generalized inflammation or rheumatoid arthritis, which leads to the leukocytes adhering and emigrating into affected organ regions, Tlie increased adhesion, vi'hich is elicited by the endotoxin, to the endothelium of the venules is dertemined.
A camera Inverted microscope {from Zeiss) which is fitted with a video system is used for determining the leukocyte adhesion. Zymosan or bacterial endotoxin is injected into male Sprague-Dawley rats (body weight: approx. 250 g) which have

been given a light halothane premedication. The control animals are given the same volume of 0.9% sodium chloride solution. The animals are then administered the test substance subcutaneously or orally as a single dose or in the form of multiple doses. For carrying out the measurement, the rats are anesthetized viflth an intramuscular injection of 1.25 g of urethane/kg. They are allowed to breathe spontaneously through an tracheal tube. A regulatable heating blanket is used to keep the body temperature at 37°C. The mesentery is carefully exposed through an abdominal opening, on a thermostated (37'C) window in the microscope table, and covered with liquid paraffin at Zl'C. The ileocecal region of the mesentery is held in position with the aid of three blunt needles and plasticine. After a 30-minute equilibration time, during which the tissue is allowed to stabilize, leukocyte adhesion is determined, in post-capillary venules of 20-30 pm in diameter and approx. 100 pm in length, by counting, in 2-3 segments of the venules, at intervals of 10 minutes over a period of 1 hour. A leukocyte is regarded as adhering to the endothelium when it is stationary for more than 30 seconds. After tie experiment, the systemic leukocyte count, and the fibrinogen content of the blood, are determined. The inhibition of leukocyte adhesion brought about by the test substance is given by the decrease (in %) in the number of adherent leukocytes in the treated animals as compared with the number in the control animals.
C} Delayed-type hypersensitivity in the mouse
The delayed-type hypersensitivity (DTH) model is used to investigate the antiallergic or antiinflammatory effect of the compounds of the formula 1, DTH is an inflammatory reaction of the skin which is induced by sensitizing with antigenic substances. In order to determine in vivo the corresponding inflammatory reaction, and the recruitment of leukocytes into the inflamed regions, the substances are tested in the following mouse DTH model (see also T...B. Issekutz, J. Immunol. 19.91,-1.47,4178).,.
Groups of female BALB/c mice (body weight: approx. 20 g) are sensitized epicutaneousiy, on a shaved part of the si^in, with 150 [i\ of a 3% solution of oxazoione, which induces a strong inflammatory DTH reaction. 6 days later, the

reaction is challenged by administering 20 pi of a 1 % oxazolone solution to the right ears of the animals. The test substances are in each case administered, subcutaneously or orally, 44 hours before the challenge of the reaction, 20 hours before the challenge of the reaction and 4 hours after the challenge of the reaction-.' Immediately before the challenge the reaction, and 24 after the challenge, a Mitutoyo Engineering micrometer is used to measure the change in the thickness in the right ear due to the inflammatory swelling of the ear. The difference between these two measurements is determined for each animal in the group. The mean values of the differences of an animal group treated with the test substance, on the one hand, and of an untreated control group, on the other hand, are compared. The percentage inhibition of the ear swelling is taken as a measure of the effect of the substance.
D) Antiasthmatic effect in the guinea pig
The ability of the compounds of the formula 1 to influence lung function and their antiasthmatic effect can be determined in a guinea pig model which is based on the method described by G. Moacevic, Arch. Toxicol. 1975, 34,1. The technical preparations for this investigation are carried out according to the details described by Moacevic. Male albino guinea pigs having a body weight of 300-500 g are used. The animals are placed in a plethysmograph (from FMi) and three initial values for the parameters respiratory frequency and respiratory amplitude are recorded. In this model, asthmatic respiration is characterized by a decrease in respiratory amplitude (- decrease in respiratory volume due to bronchoconstriction) and an increase in respiratory frequency (= reflex reaction). In asthmatic patients, this condition is known as dyspnea.
22 days before beginning the study, the albino guinea pigs are sensitized with an 0,1% solution of ovalbumin, 1 mf of which is administered per animal on two consecutive days. The experimental asthma attack is induced by the inhalation of an 0.3% ovalbumin solution for 1 minute. After s recovery phase of 40-60 minutes, the animals then inhale the test substance as an aqueous solution. Immediately after that, 0.3% ovalbumin solution is administered for 1 minute. In the following recovery

pliase of 30 minutes, the animals breathe normal air. This procedure is repeated twice. If the asthma attacks become life-threatening, the animals are administered oxygen.
The antiasthmatic effect in the sheep can be determined as described, for example, byAbrahametal., J.Clin. Invest. 1994, 93,776.
E) The antiatherosclerotic effect can be investigated in the following animal models
E1) Cuff model of neointima formation
The wild-type mice of the strain C57BL/6J are supplied by the breeding company Charles River Wiga GmbH (Sulzfeld), while the homozygous KO mice of the strain C57B[_/6J-ApoE tm1Unc(ApoE KO) are supplied by The Jackson Laboratory (Maine, USA). All the mice are between ID and 12 weeks of age at the beginning of the experiment and are kept in fully air-conditioned rooms at a temperature of 22°C. The day/night phases of the controlled light program are adjusted to periods of 12 hours in each case. The mice are first anesthetized with 60 mg of pentobarbital sodium/kg of body weight, which is given i.p. Each animal was then additionally given 0.01 mg of xylazine/10 g of body weight, administered i.m.
The mice are fixed in the supine position and the inner surfaces of each of the two hind legs are shaved and disinfected. The skin on the inner side of the left thigh is now opened by means of a longitudinai incision of about 1 cm in length and the femoral artery is isolated from the surrounding tissue and from the femoral vein and the sciatic nerve, A piece of polyethylene tubing of about 2 mm in length (internal diameter 0.58 mm, external diameter 0.965 mm, Becton Dickinson, Sparks, MD, USA) is then cut open along its length and lald'around the femoral artery and fixed using Prolene threads (7/0, 0.5 metric from Ethicon, Norderstedt). The skin is then dosed once again using a continuous suture. The right hind leg is operated on in an analogous manner but without a cuff being placed around the femoral artery. The

animal is subsequently returned to its cage. From the time of the operation onward, the animais are treated daily with the test substance.
At the end of the experiment, the mice are once again anesthetized with 60 mg of" pentobarbital sodium/kg of body weight, given i.p., and 0.01 mg of xylazine/10 g of body weight, given i.m. in order to fix the vessels in situ, each mouse is then given an injection of 4% formalin solution into the abdominal aorta. The right and left femoral arteries are then removed. The section of the artery which encompasses the region about 1 mm proximal to the cuff, the section enclosed by the cuff itself, and the vascular region 1 mm distal to the cuff, is removed on the left side. On the right side, this section corresponds to the region which is only isolated, but not enclosed by a cuff, during the operation.
The sections of the left and right femorai artery, which had been fixed in 4% fonnalin solution, are now embedded in paraffin. Several sections, which are subsequently stained with hematoxylin and eosin for software-assisted (LeicaQWin from Leica Imaging Systems, Cambridge, GB) morphometric analysis, are prepared from the region of the left artery surrounded by the cuff and from the corresponding region of the right coatrol artery.
Three tissue sections from the cuff-surrounded region of the left femoral artery, and three sections from the corresponding region of the right control artery, are evaluated per mouse. After marking of the external elastic lamina, the internal elastic lamina and the boundary between the lumen and the endotheiium, the analytical program calculates Uie following areas: lumen, neointima and media. The sizes of these areas are given in the unit pm^. The effect of a compound is indicated by the reduction in the neointima/media ratio as compared with the control group.
E2) Heart transplantation
In the allogenic heart transplantation model, transplantations are carried out between two genetically incompatible rat strains. For this, Wistar-Furth rats are used as donor

animals and Lev/is rats are used as recipient animals. The animals are obtained from the breeding company Charles River Wiga GmbH (Sulzfeld, Germany). Male Lewis rats weighing 270-330 g and aged from 2.5 to 3 months, and male Wistar-Furth rats weighing 200-250 g and aged from 1.5 to 2 months, are l^ept under constant, controlled conditions (temperature 19-22°C; relative atmospheric humidity 50-55%; the day/night phases of the controlled light program are adjusted to periods of 12 hours each).
For the operation, the rats are given a combination of 3.3 mg of xylazine/kg of body weight and 115 mg of ketamine/l(g of body weight. After the anesthetic has taken effect, the abdomen of the recipient is opened by median incision. The abdominal aorta and the inferior vena cava are separated from each other between the renal artery and vein and the ileolumbar vessels. The aorta is subsequently closed craniaily using a vessel clip. At the caudal end, a silk tf\read is laid around the two vessels and drawn tight. A second silk thread is laid loosely around the cranial end of the inferior vena cava. The donor animai is sacrificed, after the abdominal cavity has been opened, by cutting through the large abdominal blood vessels. This point in time signaled the beginning of the period during which the donor organ was ischemic. The diaphragm is then opened and the heart exposed. The superior and inferior vena cava are ligated and cut through on the side distal to the heart. A silk thread was then used to periderm a mass ligature on the pulmonary veins. The pulmonary aorta and artery are then lifted with forceps and cut through. The transplant is now freed from blood residues in the vascular system. The heart is then lifted, separated, together with the mass ligature, from the lung and stored for from one to two minutes in cold physiological NaCI solution. An end-to-side anastomosis of the aorta and the pulmonary artery of the donor organ to the abdominal artery and the inferior vena cava, respectively, of the recipient animal is then performed. After the vessel anastomoses have been completed, the venous circulation, followed by the arterial circulation, are then opened consecutively. Finally, the abdominal cavity is sealed once again using a peritoneum/muscle suUjre and a skin suture. Following the opening-up of the blood circulation and a brief recovery phase, the transplanted heart beats with a sinus frequency of from approx. 100 to 120 beats/minute. For

immunosuppression, cyclosporin A (CSA) is administered either subcutaneously (s.c.) or orally via the drinking water. After the acute rejection period has been surmounted, the dose of 25 mg/kg of body weight can be reduced, from the 15th day p.op. onvi'ard, down to 5 mg/Kg of body weight The injections are perfonned once a day in the moming in the region of the nape of the neck in the animals.
The change-over from subcutaneous CSA administration to oral CSA administration takes place on the 22nd day p.op., in order to be certain of having surmounted the acute rejection period. The substance to be investigated is administered over a period of 100 days, from the time of the operation onward. After the period of observation {100 days) has come to an end, the animals are anesthetized and the abdominal cavity is opened. The heart is then removed from the abdominal vessels, while preserving the vessel stumps, then cut into slices and stored in 4% fomialin solution. After the heart slices have been fixed, they are embedded in paraffin and stained for elastica using van Gieson's standardized histological technique. The neointimal proliferation, and the narrowing of the vascular lumen which is associated therewith, is classified in accordance with Adams et al. (Transplantation 1993, 56, 794). increased tissue formations between the internal elastic lamina and the endothelium are classified. Van Gieson's special stain, which selectively emphasizes the elastic fibers, facilitates the assessment. The effect of a compound is indicated by the reduction in neointimal proliferation, and thus in transplant atherosclerosis, as compared with the control group.
E3) Atherosclerosis model in ApoE knock-out(KO) mice
The homozygous KO mice of the strain C57BL/6J-ApoE tml Unc (ApoE KO) are supplied by The Jackson Laboratory (Maine, USA). At the beginning of the experiment, all the'mice are between 10 and 12 weeks of age and are kept on standard litter for laboratory animals (Altromin, Lage) in fuliy air-conditioned rooms at a temperature of 22'C. The day/night phases of the controlled light program are adjusted to a period of 12 hours each. The animals are treated with the test substance for 4 months.

At the end of ttie experiment, the mice are anesthe^zed with 60 mg of pentobarbital sodium/kg of body weight, given i.p., and 0.01 mgofxylazine/lOg of body weight, given i.m. The heart and aortic arch, and also the descending thoracic aorta, are then removed and fixed in 4% formalin solution. The descending aorta is treated with Oil Red O, for staining fat lesions. The morphometric analysis of the fat lesions is performed using a microscope (Leitz DM RBE type, from Leica, Bensheim), a camera which is connected to it and which possesses a control unit (CF 15 MCG type, Kappa IVlesstechnik, Gleichen) and a computer (Leica, Bensheim). The measurements are perfomied using a computer program for the image analysis (LeicaQWin from Leica imaging Systems, Cambridge, GB). The heart and the aortic arch are cut iongitudinaliy and stained with hematoxylin and eosin for the morphometric analysis. 15-20 sections are evaluated in each case. Further sections are examined immunohistochemically for macrophages and T lymphocytes. The effect of a compound is indicated by the reduction in plaque formation in the aorta as compared with the control group.
F) The cardioprotective effect can be investigated, for example, in the following animal mode!.
Cardiac infarct size in the rat
Mafe Wistar rats aged from 2.5 to 3 months and having a body weight of 270-330 g are obtained from the breeding company Charles River Wiga GmbiH (Sulsfeld, Germany). The animals are kept under constant, controlled condfUons (temperature 19-22'C; relative atmospheric humidity 50-55%; the day/night phases of the controlled light program are adjusted to periods of 12 hours each). For the operation, the rats are given a combination of 3.3 mg of xyiazine/kg of body weight and 115 mg of ketamine/kg of body weight The animals are subsequently intubated and ventilated using 30% oxygen. The thorax is shaved, disinfected and opened by means of a left-lateral thoracotomy. The left coronary artery is either ligated

pennanently, for 48 hours or for 4 weeks, 2-3 mm below the [eft auricular appendix, or else it is ligatsd for 30 minutes and reperfused for 47,5 hours or for 4 weeks.
After the operation, the thorax is dosed again and the animals are e>lubated once spontaneous respiration has begun. The test substance is administered 30 minutes after the ligation or immediately before the reperfusion. The animals are then treated daily with the test substance. At the end of the experiment, the animals are once again anesthetized with a combination of 3.3 mg of xylazine/kg of body weight and 115 mg of i^etamine/kg of body weight. For the wall movement analysis, the animals whose hearts were reperftised are examined by means of nuclear magnetic resonance imaging. In the case of animals wfiose hearts were not reperfused, a tip catheter, for measuring the ventricular pressure and contractiiity, is introduced, via carotid artery, into the left ventricle. After that, the hearts of ail the animals are removed and perfused in a Langendorff apparatus, in a retrograde manner, via the aorta, with 1 % Evans Blue solution at 37°C, In order to detennine the anatomic area at risk and the nonischemic area. Subsequently, the hearts are cut into 5-6 thin slices and incubated for 15 minutes in 2,3,5-triphenyltetrazoiium chloride solution for the purpose of determining the vitai heart tissue and the dead heart tissue. The pianimetric analysis of the area at risk and of the infarction region is performed using a camera (Leica, Bensheim) and an attached computer unit with analytical software (Leitz, Bensheim). The area at risk is expressed in percent based on the left ventricle plus septum and the infarction region in percent based on the area at risk. The effect of a compound is indicated by the reduction in the infarction region based on the area at risk as compared with the control group.
