Full Text TRICYCLIC LACTAM DERIVATIVES AS 11-BETA HYDROXYSTEROID DEHYDROGENASE INHIBITORS
The metabolic syndrome is a disease with increasing prevalence not only in the
Western world but also in Asia and developing countries. It is characterised by obesity
in particular central or visceral obesity, type 2 diabetes, hyperlipidemia, hypertension,
arteriosclerosis, coronary heart diseases and eventually chronic renal failure (C.T.
Montague et al. (2000), Diabetes, 49, 883-888).
Glucocorticoids and 11J3-HSD1 are known to be important factors in differentiation of
adipose stromal cells into mature adipocytes. In the visceral stromal cells of obese
patients, 11|3-HSD1 mRNA level is increased compared with subcutaneous tissue.
Further, adipose tissue over-expression of 11P-HSD1 in transgenic mice is associated
with increased corticosterone levels in the adipose tissue, visceral obesity, insulin
sensitivity, Type 2 diabetes, hyperlipidemia and hyperphagia (H. Masuzaki et al (2001),
Science, 294, 2166-2170). Therefore, 11P-HSD1 is most likely be involved in the
development of visceral obesity and the metabolic syndrome.
Inhibition of 11P-HSD1 results in a decrease in differentiation and an increase
in proliferation of adipose stromal cells. Moreover, glucocorticoid deficiency
(adrenalectomy) enhances the ability of insulin and leptin to promote anorexia and
weight loss, and this effect is reversed by glucocorticoid administration (P.M. Stewart
et al (2002), Trends Endocrin. Metabpl, 13, 94-96). These data suggest that enhanced
reactivation of cortisone by 11P-HSD1 may exacerbate obesity and it may be beneficial
to inhibit this enzyme in adipose tissue of obese patients.
Obesity is also linked to cardiovascular risks. There is a significant relationship
between cortisol excretion rate and HDL cholesterol in both men and women,
suggesting that glucocorticoids regulate key components of cardiovascular risk. In
analogy, aortic stiffness is also associated with visceral adiposity in older adults.
The impact of the effect of decreased 11P-HSD1 activity is highlighted by the
P-HSD1 knockout mouse that has increased plasma levels of endogenous active
glucocorticoid, but inspite of this remains protected from insulin resistance induced by
stress and obesity. Additionally, these knockout mouse present an anti-atherogenic
plasmid lipid profile and benefits from decreased age-related cognitive impairement.
Glucocorticoids and glaucoma
Glucocorticoids increase the risk of glaucoma by raising the intraocular pressure when
administered exogenously and in certain conditions of increased production like in
Gushing's syndrome. Corticosteroid-induced elevation of intra ocular pressure is
caused by increased resistance to aqueous outflow due to glucocorticoid induced
changes in the trabecular meshwork and its intracellular matrix. Zhou et al. (Int J Mol
Med (1998) 1, 339-346) also reported that corticosteroids increase the amounts of
fibronectin as well as collagen type I and type IV in the trabecular meshwork of organcultured
bovine anterior segments.
11P-HSD1 is expressed in the basal cells of the corneal epithelium and the nonpigmented
epithelial cells. Glucocorticoid receptor mRNA was only detected in the
trabecular meshwork, whereas in the non-pigmented epithelial cells mRNA for the
glucocorticoid-, mineralocorticoid receptor and 11J3-HSD1 was present. Carbenoxolone
administration to patients resulted in a significant decrease in mtra-ocular pressure (S.
Rauz et al. (2001), Invest. Ophtalmol. Vis. Science, 42, 2037-2042), suggesting a role
for HSD1-inhibitors in treating glaucoma.
Accordingly, the underlying problem to be solved by the present invention was to
identify potent 11 (3-HSD inhibitors, with a high selectivity for 11 p-HSDl, and the use
thereof in treating pathologies associated with excess cortisol formation, i.e. disorders
where a decreased level of active glucocorticoid is desirable, such as metabolic
syndrome, type 2 diabetes, impaired glucose tolerance (IGT), impaired fasting glucose
(IFG), dyslipidemia, hypertension, obesity, diabetes, obesity related cardiovascular
diseases, arteriosclerosis, atherosclerosis, myopathy, osteoporosis, neurodegenerative
and psychiatric disorders, stress related disorders and glaucoma. As shown
hereinbelow, the 3-substituted 2-pyrrolidinone derivatives of formula (I) were found to
be useful as a medicine, in particular in the manufacture of a medicament for the
treatment of pathologies associated with excess cortisol formation.
Blommaert A. et al. (Heterocycles (2001), 55(12), 2273-2278) provides the preparation
of piperidine- and pyrrolidinone-like polymer supported (R)-phenylglycinol-derived
scaffolds and in particular discloses 2-Pyrrolidinone, l-[(lR)-2-hydroxy-lphenylethyl]-
3-methyl-3-(phenyhnethyl)- and 2-Pyrrolidinone, l-[(lR)-2-hydroxy-lphenylethyl]-
3-(phenylmethyl)-, (3R).
Bausanne I. et al. (Tetrahedron: Assymetry (1998), 9(5), 797-804) provides the
preparation of 3-substituted pyrrolidinones via oc-alkylation of a chiral non-racemic
y-lacton and in particular discloses 1 -(2-hydroxy-1 -phenylethyl)-3-benzylpyrrolidin-2-
one.
US 2001/034343; US 6,211,199; US 6,194,406; WO 97/22604 and WO 97/19074 are a
number of patent applications filed by Aventis Pharmaceuticals Inc. providing 4-(lHbenzimidazol-
2-yl)[l,4]diazepanes useful for the treatment of allergic diseases. In
these applications the 3-substituted pyrrolidinones of the present invention are
disclosed as intermediates in the synthesis of said 4-(lH-benzimidazol-2-yl)[l,4]-
diazepanes. These applications in particular disclose; 2-Pyrrolidinone, 3-[(4-fluorophenyl)
methyl]-l-[(lS)-l-phenylethyl]- and 2-Pyrrolidinone, 3-[(4-fluorophenyl)-
methy]]-l-[(lR)-l-phenylethyl]-.
Adamantyl like compounds are also disclosed in PCT publication WO 03065983
(Merck & Co., Inc.) and WO 2004056744 (Janssen Pharmaceutica N.V.). Taking WO
2004056744 as the closest prior art, the compounds of the present application differ in
that the adamantyl ring is linked to a ring amide nitrogen being part of a tricyclic
system. Notwithstanding the fact that WO 03065983 discloses that the adamantyl ring
may be directly linked to a tricyclic ring system, it should be noted that said tricyclic
ring systems are characterised in having 2-adamantyl-triazole as a core structural
element and that it was accordingly not to be expected that replacing the triazole with a
imidazolidinone or pyrrolidinone could be done without loss of the desired activity, i.e.
potent 11 p-HSD inhibitors, with a selectivity for 11 (3-HSD1.
Hence, in none of the cited documents the therapeutic application of the tricyclic
adamantylamide derivatives of the present invention has been disclosed nor suggested.

The "curved" tricyclic adamantylamide derivatives of the present invention, hereinafter
referred to as the compounds of formula (I1), are generally prepared by condensing in a
first step the commercially available benzocyclobutane carboxylic acid (II) with the
appropriate amine under art known conditions (Scheme 1). Subsequently, the thus
obtained amide (III) is reduced using for example, lithium aluminium hydride or borane
dimethyl sulphide complex, to give the amine of formula (IV). Finally, said amine is
acylated with acroyl chloride followed by a cyclisation reaction, under art known
procedures, such as for example by heating the amide (V) in toluene at 190°C, to yield
a mixture of the cis and trans isomers of the "curved" tricyclic adamantylamide
derivatives of the present invention.
wherein R2 is defined as for the compounds of formula (I) hereinbefore.
To obtain the stereoisomers of the "curved" tricyclic adamantylamide derivatives of
formula (I1) hereinbefore, the commercially available benzocyclobutane carboxylic acid
(II) is condensed with allyl-2-adamantyl-amine (VI) to yield the amide of general
formula (VII), which upon electrocyclic ring closure afforded the "curved" tricyclic
adamantylamide derivatives of formula (I") (Scheme 2).
wherein R1 and R2 are defined as for the compounds of formula (I) hereinbefore.
Those compounds of formula (I) wherein X represents N, hereinafter referred to as the
ureas of formula (I1U) are generally prepared according to reaction schemes 3 and 4
hereinafter. In a first alternative, the ureas are prepared starting from commercially
available Boc-protected tetrahydroquinoline-3-carboxylic acid (both enantiomers),
reaction with aminoadamantane and reduction of the amide gave the diamine of fomula
(VIII). Subsequent cyclization under art known procedures gave the cyclic ureas of
In a second alternative the urea derivatives are prepared by coupling the commercially
available quinoline-2-carboxylic acids or isoquinoline-1-carboxylic acids with the
appropriate amine under art known procedures to yield the corresponding amide of
formula (IX). Selective hydrogenation of the pyridine ring afforded the
tetrahydro(iso)quinolines acetamides (X), which were reduced using for example,
BH3.DMS in toluene to yield the diamines of general formula (XI). Subsequent
cyclization, using for example carbonyl diimidazole (GDI) gave the cyclic ureas of
wherein R2 is defined as for the compounds of formula (I) hereinbefore,
-A-A- represents -N-CHj- or -CHz-N- and -A=A- represents -N=CHor-
CH=N-.
In those cases where the substituted isoquinoline-1-carboxylic acids were not
commercially available, the substituted tricyclic derivatives were built up starting from
phenethylarnines (XII) and ethylchloroformate (Scheme 5). The created carbamate was
cyclized using art known procedures, such as for example the modified Bischler-
Napierelski reaction (Larsen, Robert D., et al., A modified Bischler-Napieralski
procedure for the synthesis of 3-aryl-3,4-dihydroisoquinolines., Journal of Organic
Chemistry (1991), 56(21), 6034-8.), to give the ammo protected
tetrahydroisoquinoline-1-carboxylic acid of formula (X'). The further synthesis of the
substituted tricyclic derivatives is as described in reaction Scheme 4 hereinbefore.
The "linear" tricyclic adamantylamide derivatives of formula (I1V) can be prepared
according to reaction schemes 6 and 7 herein after. According to a first alternative the
linear tricyclic adamantylamide derivatives are prepared starting from the aryl- or
heteroaryl-substituted acrylic acid or acid chloride (XIII). Reaction with the
appropriate amine gives the amide of formula (XFV), which upon electrocyclic ring
closure under art known conditions, for example in toluene at 220°C, provides the
tricyclic system of
wherein A and R are defined as for the compounds of formula (I) hereinbefore.
In a second alternative the "linear" tricyclic adamantylamide derivatives of formula
(I1V) wherein A represents phenyl and Y represents N, can be prepared by coupling the
amino protected D or L-phenylalanine with the appropriate amine to give the aaminoamide
of formula (XV), see for example the reaction conditions as described in
J.Org.Chem. 2002, 67, 8224. Deprotection followed by Mannich condensation with
benzotriazole and formaldehyde provides the intermediate of formula (XVI).
Electrocyclic ring closure provides the "linear" tricyclic adamantylamide derivatives of

above-mentioned synthesis methods, are provided in the experimental part hereinafter.
Where, necessary or desired, any one or more of the following further steps in any order
may be performed:
(i) removing any remaining protecting group(s);
(ii) converting a compound of formula (I) or a protected form thereof into a further
compound of formula (I) or a protected form thereof;
(iii) converting a compound of formula (I) or a protected form thereof into a JV-oxide, a
salt, a quaternary amine or a solvate of a compound of formula (I) or a protected
form thereof;
(iv) converting a Af-oxide, a salt, a quaternary amine or a solvate of a compound of
formula (I) or a protected form thereof into a compound of formula (I) or a protected
form thereof;
(v) converting a N-oxide, a salt, a quaternary amine or a solvate of a compound of
formula (I) or a protected form thereof into another A^-oxide, a pharmaceutically
acceptable addition salt a quaternary amine or a solvate of a compound of formula
(I) or a protected form thereof;
(vi) where the compound of formula (I) is obtained as a mixture of (R) and (S)
enantiomers resolving the mixture to obtain the desired enantiomer.
It will be appreciated by those skilled in the art that in the processes described above
the functional groups of intermediate compounds may need to be blocked by protecting
groups.
Functional groups which it is desirable to protect include hydroxy, amino and
carboxylic acid. Suitable protecting groups for hydroxy include trialkylsilyl groups
(e.g. tert-butyldimethylsilyl, tert-butyldiphenylsilyl or trimethylsilyl), benzyl and
tetrahydropyranyl. Suitable protecting groups for amino include tert-butyloxycarbonyl
or benzyloxycarbonyl. Suitable protecting groups for carboxylic acid include C^alkyl
or benzyl esters.
The protection and deprotection of functional groups may take place before or after a
reaction step.
The use of protecting groups is fully described in 'Protective Groups in Organic
Synthesis' 2nd edition, T W Greene & P G M Wutz, Wiley Interscience (1991).
Additionally, the N-atoms in compounds of formula (I) can be methylated by artknown
methods using CHs-T in a suitable solvent such as, for example 2-propanone,
tetrahydroiiiran or dimethylformamide.
The compounds of formula (I), can also.be converted into each other following artknown
procedures of functional group transformation of which some examples are
mentioned hereinabove.
The compounds of formula (I), may also be converted to the corresponding AT-oxide
forms following art-known procedures for converting a trivalent nitrogen into its
N-oxide form. Said JV-oxidation reaction may generally be carried out by reacting the
starting material of formula (I) with 3-phenyl-2-(phenylsulfonyl)oxaziridine or with an
appropriate organic or inorganic peroxide. Appropriate inorganic peroxides comprise,
for example, hydrogen peroxide, alkali metal or earth alkaline metal peroxides, e.g.
sodium peroxide, potassium peroxide; appropriate organic peroxides may comprise
peroxy acids such as, for example, benzenecarboperoxoic acid or halo substituted
benzenecarboperoxoic acid, e.g. 3-chlorobenzenecarboperoxoic acid, peroxoalkanoic
acids, e.g. peroxoacetic acid, alkylhydroperoxides, e.g. t-butyl hydroperoxide. Suitable
solvents are, for example, water, lower alkanols, e.g. ethanol and the like, hydrocarbons,
e.g. toluene, ketones, e.g. 2-butanone, halogenated hydrocarbons, e.g.
dichloromethane, and mixtures of such solvents.
Pure stereochemically isomeric forms of the compounds of formula (I), may be
obtained by the application of art-known procedures. Diastereomers may be separated
by physical methods such as selective crystallization and chromatographic techniques,
e.g. counter-current distribution, liquid chromatography and the like.
Some of the compounds of formula (I), and some of the intermediates in the present
invention may contain an asymmetric carbon atom. Pure stereochemically isomeric
forms of said compounds and said intermediates can be obtained by the application of
art-known procedures. For example, diastereoisomers can be separated by physical
methods such as selective crystallization or chromatographic techniques, e.g. counter
current distribution, liquid chromatography and the like methods. Enantiomers can be
obtained from racemic mixtures by first converting said racemic mixtures with suitable
resolving agents such as, for example, chiral acids, to mixtures of diastereomeric salts
or compounds; then physically separating said mixtures of diastereomeric salts or
compounds by, for example, selective crystallization or chromatographic techniques,
e.g. liquid chromatography and the like methods; and finally converting said separated
diastereomeric salts or compounds into the corresponding enantiomers. Pure
stereochemically isomeric forms may also be obtained from the pure stereochemically
isomeric forms of the appropriate intermediates and starting materials, provided that the
intervening reactions occur stereospecifically.
An alternative manner of separating the enantiomeric forms of the compounds of
formula (I) and intermediates involves liquid chromatography, in particular liquid
chromatography using a chiral stationary phase.
Some of the intermediates and starting materials as used in the reaction procedures
mentioned hereinabove are known compounds and may be commercially available or
may be prepared according to art-known procedures.
The compounds of the present invention are useful because they possess
pharmacological properties. They can therefore be used as medicines, in particular to
treat pathologies associated with excess cortisol formation, i.e. disorders where a
decreased level of active glucocorticoid is desirable, such as metabolic syndrome, type
2 diabetes, impaired glucose tolerance (IGT), impaired fasting glucose (IFG),
dyslipidemia, hypertension, obesity, diabetes, obesity related cardiovascular diseases,
arteriosclerosis, atherosclerosis, myopathy, osteoporosis, neurodegenerative and
psychiatric disorders, stress related disorders and glaucoma. In particular to treat
pathologies such as for example, obesity, diabetes, type 2 diabetes, obesity related
cardiovascular diseases, stress and glaucoma.
As described in the experimental part hereinafter, the inhibitory effect of the present
compounds on the 11 p-HSD 1 -reductase activity (conversion of cortisone into cortisol)
has been demonstrated in vitro, in an enzymatic assay using the recombinant 1 Ib-
HSD1 enzyme, by measuring the conversion of cortisone into cortisol using HPLC
purification and quantification methods. 11 (3-HSD1 -reductase inhibition was also
demonstrated in vitro, in a cell based assay comprising contacting the cells, expressing
11(3-HSD1 with the compounds to be tested and assessing the effect of said compounds
on the formation of cortisol in the cellular medium of these cells. The cells preferably
used in an assay of the present invention are selected from the group consisting of
mouse fibroblast 3T3-L1 cells, HepG2 cells, pig kidney cell, in particular LCC-PK1
cells and rat hepatocytes.
Accordingly, the present invention provides the compounds of formula (I) and their
pharmaceutically acceptable JV-oxides, addition salts, quaternary amines and
stereochemically isomeric forms for use in therapy. In particular to treat pathologies
associated with excess cortisol formation, i.e. disorders where a decreased level of
active glucocorticoid is desirable, such as metabolic syndrome, type 2 diabetes,
impaired glucose tolerance (IGT), impaired fasting glucose (DFG), dyslipidemia,
hypertension, obesity, diabetes, obesity related cardiovascular diseases, arteriosclerosis,
atherosclerosis, myopathy, osteoporosis, neurodegenerative and psychiatric disorders,
stress related disorders and glaucoma. More particular to treat pathologies such as for
example, obesity, diabetes, type 2 diabetes, obesity related cardiovascular diseases,
stress and glaucoma. Even more particular in the treatment or prevention of
pathologies associated with excess cortisol formation such as obesity, diabetes, obesity
related cardiovascular diseases and glaucoma.
In view of the utility of the compounds according to the invention, there is provided a
method for the treatment of an animal, for example, a mammal including humans,
suffering from a pathology associated with excess cortisol formation, which comprises
administering an effective amount of a compound according to the present invention.
Said method comprising the systemic or topical administration of an effective amount
of a compound according to the invention, to warm-blooded animals, including
humans.
It is thus an object of the present invention to provide a compound according to the
present invention for use as a medicine. In particular to use the compound according to
the present invention in the manufacture of a medicament for treating pathologies
associated with excess cortisol formation such as for example, metabolic syndrome,
type 2 diabetes, impaired glucose tolerance (IGT), impaired fasting glucose (IFG),
dyslipidemia, hypertension, obesity, diabetes, obesity related cardiovascular diseases,
arteriosclerosis, atherosclerosis, myopathy, osteoporosis, neurodegenerative and
psychiatric disorders, stress related disorders and glaucoma, in particular obesity,
diabetes, obesity related cardiovascular diseases, stress and glaucoma.
The amount of a compound according to the present invention, also referred to here as
the active ingredient, which is required to achieve a therapeutical effect will be, of
course, vary with the particular compound, the route of administration, the age and
condition of the recipient, and the particular disorder or disease being treated. A
suitable daily dose would be from 0.001 mg/kg to 500 mg/kg body weight, in particular
from 0.005 mg/kg to 100 mg/kg body weight. A method of treatment may also include
administering the active ingredient on a regimen of between one and four intakes per
day.
While it is possible for the active ingredient to be administered alone, it is preferable to
present it as a pharmaceutical composition. Accordingly, the present invention further
provides a pharmaceutical composition comprising a compound according to the
present invention, together with a pharmaceutically acceptable carrier or diluent. The
carrier or diluent must be "acceptable" in the sense of being compatible with the other
ingredients of the composition and not deleterious to the recipients thereof.
The pharmaceutical compositions of this invention may be prepared by any methods
well known in the art of pharmacy, for example, using methods such as those described
in Gennaro et al. Remington's Pharmaceutical Sciences (18th ed., Mack Publishing
Company, 1990, see especially Part 8 : Pharmaceutical preparations and their
Manufacture). A therapeutically effective amount of the particular compound, in base
form or addition salt form, as the active ingredient is combined in intimate admixture
with a pharmaceutically acceptable carrier, which may take a wide variety of forms
depending on the form of preparation desired for administration. These pharmaceutical
compositions are desirably in unitary dosage form suitable, preferably, for systemic
administration such as oral, percutaneous, or parenteral administration; or topical
administration such as via inhalation, a nose spray, eye drops or via a cream, gel,
shampoo or the like. For example, in preparing the compositions in oral dosage form,
any of the usual pharmaceutical media may be employed, such as, for example, water,
glycols, oils, alcohols and the like in the case of oral liquid preparations such as
suspensions, syrups, elixirs and solutions: or solid carriers such as starches, sugars,
kaolin, lubricants, binders, disintegrating agents and the like in the case of powders,
pills, capsules and tablets. Because of their ease in administration, tablets and capsules
represent the most advantageous oral dosage unit form, in which case solid pharmaceutical
carriers are obviously employed. For parenteral compositions, the carrier will
usually comprise sterile water, at least in large part, though other ingredients, for
example, to aid solubility, may be included. Injectable solutions, for example, may be
prepared in which the carrier comprises saline solution, glucose solution or a mixture of
saline and glucose solution. Injectable suspensions may also be prepared in which case
appropriate liquid carriers, suspending agents and the like may be employed. In the
compositions suitable for percutaneous administration, the carrier optionally comprises
a penetration enhancing agent and/or a suitable wettable agent, optionally combined
with suitable additives of any nature in minor proportions, which additives do not cause
any significant deleterious effects on the skin. Said additives may facilitate the
administration to the skin and/or may be helpful for preparing the desired compositions.
These compositions may be administered in various ways, e.g., as a transdermal patch,
as a spot-on or as an ointment. As appropriate compositions for topical application
there may be cited all compositions usually employed for topically administering drugs
e.g. creams, gellies, dressings, shampoos, tinctures, pastes, ointments, salves, powders
and the like. Application of said compositions may be by aerosol, e.g. with a propellant
such as nitrogen, carbon dioxide, a freon, or without a propellant such as a pump spray,
drops, lotions, or a semisolid such as a thickened composition which can be applied by
a swab. In particular, semisolid compositions such as salves, creams, gellies, ointments
and the like will conveniently be used.
It is especially advantageous to formulate the aforementioned pharmaceutical
compositions in dosage unit form for ease of administration and uniformity of dosage.
Dosage unit form as used in the specification and claims herein refers to physically
discrete units suitable as unitary dosages, each unit containing a predetermined quantity
of active ingredient calculated to produce the desired therapeutic effect in association
with the required pharmaceutical carrier. Examples of such dosage unit forms are
tablets (including scored or coated tablets), capsules, pills, powder packets, wafers,
injectable solutions or suspensions, teaspoonfuls, tablespoonfuls and the like, and
segregated multiples thereof.
In order to enhance the solubility and/or the stability of the compounds of formula (I) in
pharmaceutical compositions, it can be advantageous to employ a-, |3- or y-cyclodextrins
or their derivatives. Also co-solvents such as alcohols may improve the
solubility and/or the stability of the compounds of formula (I) in pharmaceutical
compositions. In the preparation of aqueous compositions, addition salts of the subject
compounds are obviously more suitable due to their increased water solubility.
