Full Text DESCRIPTION
Glycine Derivative and Use Thereof
Technical Field
[0001]
The present invention relates to a glycine derivative and its medical use,
particularly a therapeutic agent for inflammatory bowel disease.
Background Art
[0002]
Inflammatory bowel disease is a collective name of ulcerative colitis and
Crohn's disease. Ulcerative colitis is a non-specific chronic inflammatory disease in
which mucosal damage in large intestine diffusely and continuously ascends from
rectum. . On the other hand, in Crohn's disease, inflammation is observed at various
sites in gastrointestinal tract, and transmural conditions such as deep ulcer and
perforation are observed. Although the pathogenesis of these diseases is not known,
various causes such as infections, environmental factors, psychosomatic medical
problems, inheritance and immune abnormality are assumed, and the diseases are
generally thought to be multiple-cause diseases caused by being complexly
intertwined with the above-described factors.
[0003]
The major symptoms of ulcerative colitis are mucous and bloody stool,
abdominal pain and diarrhea, and anemia and tachycardia are observed depending on
the degree of bleeding. Inappetence, weight loss, general malaise and easy
fatigability are also observed in some cases. Complications in intestinal tract
include massive bleeding, perforation, toxic megacolon and occurrence of colon
cancer. Complications in organs other than intestinal tract include skin diseases
such as erythema nodosum and pyoderma, ophthalmic diseases such as conjunctivitis
and iridocyclitis, and stomatitis, and primary sclerosing cholangitis is rarely observed.

[0004]
The most frequent symptoms of Crohn's disease are diarrhea and abdominal
pain. Further, fever, melena, weight loss due to impaired absorption, general
malaise, anal pain and anemia are often observed. Complications in intestinal tract
include constriction, fistula and adhesion. Complications in organs other than
intestinal tract include skin diseases such as necrotic pyoderma and erythema
nodosum, joint disease, stomatitis, cholangitis and fatty liver. Crohn's disease is
classified into small intestinal type, small and large intestinal type and large intestinal
type.
Peak of onset of inflammatory bowel disease is in twenties, and recurrence
and remission are easy to be repeated, so that frequently, QOL is seriously disturbed.
Further, since the number of patients is increasing due to the recent changes of
environmental factors such as the change in dietary life, the importance of therapy of
inflammatory bowel disease is increasing year by year.
[0005]
Therapy for inflammatory bowel disease is performed by means of
pharmacotherapy, apheresis or surgical therapy. Pharmacotherapy includes the
remission-induction therapy in which the symptoms are alleviated and remission is
quickly induced, and the prophylactic remission-maintenance therapy in which the
remission period is prolonged. In the remission-induction, in cases where the
symptoms are slight or moderate, the therapy is based on oral administration of
salazosulfapyridine or 5-aminosalicylic acid. These drugs are also used for the
prophylactic remission-maintenance therapy. If the effects of the drugs are
insufficient or the symptoms are more serious, adrenocortical steroids or
immunosuppressive agents are used.
[0006]
Therapy for Crohn's disease is mainly performed by means of nutritional

therapy, pharmacotherapy or surgical treatment. The pharmacotherapy is based on
5-aminosalicylic acid preparation, and adrenocortical steroids or immunosuppressive
agents are used depending on the symptoms.
[0007]
Recently, it has been proved that local cytokines strongly participate in the
pathogenesis of inflammatory bowel disease, and studies on the drugs targeting the
cytokines are underway. Anti-TNF-α antibody therapy targeting TNF-a, which is
a key cytokine of Crohn's disease, is presently used for the amelioration of the lesion
or for decreasing the amount of steroids.
[0008]
However, known therapeutic agents for inflammatory bowel disease does not
sufficiently satisfy the needs of users with respect to the purpose such as amelioration
of symptoms or reduction of side effects.
[0009]
It is known that leukocytes strongly participate in the development of
inflammatory bowel disease. In recent years, a number of trials for inhibiting the
development of the disease are underway using monoclonal antibodies, antisenses or
low molecular compounds which inhibit the activation or hyperfunction of
leukocytes, or which inhibit the proinflammatory substance produced by leukocytes.
Examples of the target molecules include CD4 which is a surface molecule expressed
on leukocytes, adhesive molecules, regulatory molecules of T cell activation (CD40L,
CD28 and CTLA-4), phosphorylation signals of leukocytes, transcription factors,
various inflammatory chemical mediators such as inflammatory cytokines and LTB4,
active oxygen and various enzymes (PDEIV, lipoxygenase and the like). The
therapeutic effects by inhibiting these molecules on inflammatory bowel disease have
been proved by using monoclonal antibodies or low molecular inhibitors in human
clinical studies or in experimental animal models (see, for example, Non-patent

Literature 1, Non-patent Literature 2 and Non-patent Literature 3).
[0010]
In the lesion tissues in inflammatory bowel disease, prominent infiltration of
leukocytes is observed. It is widely recognized that the infiltration is due to the
leukocytes normally circulating in the blood which penetrate the vascular wall,
resulting in gathering of the leukocytes at the lesion tissues. It has been proved that
infiltration of the leukocytes via vascular endothelium is caused by the interaction
between integrins on the leukocytes and adhesion molecules which belong to the
immunoglobulin family such as ICAM-1 and VCAM-1 on the vascular endothelial
cells.
[0011]
Intercellular adhesion molecule-1 (ICAM-1: CD54) is an adhesion molecule
belonging to the immunoglobulin super family, and mainly exists on vascular
endothelium. ICAM-1 binds to lymphocyte function associated antigen-1 (LFA-1:
integrin a Lβ2, CD 11 a/CD18) and Mac-1 (integrin aM(32, CD1 lb/CD 18) on
leukocytes, and is involved in extravasation of inflammatory cells (see, for example,
Non-patent Literature 4). Existence of vascular cell adhesion molecule-1 (VCAM-
1) also has been confirmed in intestinal mucosal tissues (see, for example, Non-
patent Literature 5), and the molecule is involved in extravasation of leukocytes by
binding to very late activating antigen-4 (VLA-4: integrin α4β1)(see, for example,
Non-patent Literature 6). Further, as an adhesion molecule specific to the
endothelial cells in gut-associated lymphoid tissues, mucosal addressing cell
adhesion molecule-1 (MAdCAM-1) is known. MAdCAM-1 binds to lymphocyte
Peyer's patch HEV adhesion molecule-1 (LPAM-1: integrin α4β7), and plays an
important role in gut immunity (see, for example, Non-patent Literature 7 and Non-
patent Literature 8). It is also known that integrin α4β7 binds to VCAM-1 similar
to integrin α4β1 (see, for example, Non-patent Literature 9). The therapeutic

effects on inflammatory bowel disease by inhibiting the binding between the
adhesion molecules and their integrin receptors have been proved by using antisenses
to ICAM-1 or monoclonal antibodies to integrin α4 in human clinical studies (see,
for example, Non-patent Literature 10) or in experimental animal models (see, for
example, Non-patent Literature 11, Non-patent Literature 12 and Non-patent
Literature 13).

the leukocytes, neutrophils, monocytes, lymphocytes, which are originated from
peripheral blood, or established cell lines thereof, are used. For the evaluations of
the leukocyte functions and the inflammatory mediators, the methods described in,
for example, Current Protocols in Immunology (John Wiley & Sons, Inc) are used,
but the evaluation methods are not restricted thereto.

thereof per se, or an additive(s) such as a vehicle, stabilizer, preservative, buffering
agent, solubilizer, emulsifier, diluent and/or isotonic agent, may be admixed
appropriately. The drug may be produced by a conventional method by
appropriately using these pharmaceutical carriers. Examples of the administration
mode include oral preparations such as tablets, capsules, granules, powders and
syrups; parenteral preparations such as inhalants, injection solutions, suppositories

above-described effective ingredient in an amount of 0.001 to 90% by weight, more
preferably 0.01 to 70% by weight. Although the dose may be selected depending on
the symptoms, age, body weight, sex, administration method and the like, in case of
an injection solution, a dose of 0.01 mg to 5 g, and in case of an oral preparation, a

together with other drug(s) for complementation or enhancement of the prophylactic
or therapeutic effect, or for decreasing the dose.

to male SD rats (7 to 9 weeks old). Blood was collected from the tail vein at time
points up to 8 hours after the administration, and blood plasma was collected by
centrifugation from each obtained blood. The blood plasma was pretreated by using
the solid-phase extraction methbd, and the concentration of the compound was
analyzed with LC/MS/MS (ESI negative mode).
[0460]
The obtained pharmacokinetic parameters are summarized in Table 17. As
the Comparative Compound, 2-[4-((3,5-
dichlorobenzensulfonylamino)methyl)benzoylamino]-5-(4-(methyl-pyrimidin-2-
ylamino)phenyl)pento-4-ene acid (XXI) described in WO 99/26923 was used.

[0464]
As is apparent from Table 17, the compounds in the present invention have
excellent bioavailabilities. Furthermore, they are excellent in in vivo stability, so
that the frequency of administration and dose may be reduced.
Example 86
[0465]
Measurement of Inhibitory Effect on Leukocyte Functions
Jurkat cells which are a cell line originated from human acute T cell
lymphoma were allowed to react with BCECF-AM at 37°C for 20 minutes to
fluorescently label the cells. The fluorescently labelled Jurkat cells were allowed to
react with ligand-expressing cells or with a ligand-immobilized plate at 37°C for 30
minutes. After removing non-adherent cells by washing, 1% NP40 was added to

lyse the adherent cells, and fluorescence intensity was measured with Cytoflow 2300
(Millipore). From the obtained fluorescence intensity, the number of adherent cells
was calculated. Each test compound was reacted with the Jurkat cells before the
beginning of the adhesion reaction. In Table 18, the IC50 of each compound is
shown.

As is apparent from Table 18, the compounds in the present invention clearly
inhibit functions of leukocytes involved in the development of inflammatory bowel

disease, so that they exhibit therapeutic and/or prophylactic actions against
inflammatory bowel disease.
Example 87
[0468]
Measurement of Inhibitory Effect on Inflammatory Mediator Production by
Leukocytes
A mixture of human peripheral blood and physiological saline containing 3%
dextran was left to stand for 30 minutes and then the upper layer was recovered.
The upper layer was overlaid on Histopaque 1077 (SIGMA), and the resultant was
centrifuged at 1400 rpm for 30 minutes. The supernatant was removed by
aspiration and a buffer was added to the precipitate to prepare a neutrophil
suspension (4 x 105 cells/mL). To the neutrophil suspension, ionomycin was added
and the mixture was incubated at 37°C for 30 minutes, followed by quantification of
leukotriene B4 by EIA (Amersham, Biotrak EIA system). Each test compound was
added to the neutrophil suspension before adding ionomycin. In Table 19, the IC50
of each compound is shown.
[0469]

[0470]
As is apparent from Table 19, the compounds in the present invention inhibit
production of inflammatory mediators by leukocytes involved in the development of
inflammatory bowel disease, so that they exhibit therapeutic and/or prophylactic
actions against inflammatory bowel disease.

Example 88
[0471]
Inhibitory Effect of Compounds in Dextran Sulfate Sodium (DSS)-induced Colitis
Model of mice (1)
Female BALB/c mice (Charles River, Japan) of 7 to 9 weeks old were
allowed to freely drink 3 w/v% dextran sulfate sodium (DSS) for 8 days to induce
colitis. The non-induced (background) group was allowed to freely drink sterilized
distilled water. The compound described in Example 28 was orally administered to
the mice at a dose of 5 mg/kg, and the compounds described in Example 4, Example
22 and Example 78 were orally administered to the mice at a dose of 15 mg/kg every
day. At day8 from the beginning of the drinking, stool consistency was scored (0:
normal stool, 2: loose stool, 4: diarrhea) by using the method described by Murthy et
al (see, for example, Dig Dis Sci., 38, 1722 (1993)).
[0472]
The score of the non-induced group was 0, while the score of the colitis-
induced group was 1.0 to 1.8. On the other hand, the scores of the groups which
received the compounds were lower than the score of the colitis-induced group,
showing the evident amelioration of symptom. The rate of amelioration by the
compound described in Example 28 was 71%, that of the compound described in
Example 4 was 44%, that of the compound described in Example 22 was 67% and
that of the compound described in Example 78 was 40%.
[0473]
As is apparent from the results, the compounds of the present invention have
an excellent therapeutic effect on inflammatory bowel disease.
Example 89
[0474]
Inhibitory Effect of Compounds in Dextran Sulfate Sodium (DSS)-induced Colitis

Model of mice (2)
Female BALB/c mice (Charles River, Japan) of 7 to 9 weeks old were
allowed to freely drink 3 w/v% dextran sulfate sodium (DSS) for 5 to 7 days, and
then to freely drink sterilized distilled water for 5 days. The procedure was repeated
3 times to induce colitis. The non-induced (background) group was allowed to
freely drink sterilized distilled water. The compounds described in Examples 81
and 84 were orally administered to the mice at a dose of 5 mg/kg, respectively, every
day from Day 27 to Day 31 after from the beginning of the drinking, and stool
consistency was scored (0: normal stool, 2: loose stool, 4: diarrhea) by using the
method described by Murthy et al (see, for example, Dig Dis Sci., 38, 1722 (1993).
[0475]
The score of the non-induced group was 0, while the score of the colitis-
induced group was 1.6 to 1.7. On the other hand, it was demonstrated that the
scores of the groups which received the compounds were lower than the score of the
colitis-induced group, showing the evident amelioration of symptom. The rates of
amelioration by the compounds described in Example 81 and Example 84 were
68.8% and 82.4%, respectively.
[0476]
As is apparent from the results, the compounds in the present invention have
an excellent therapeutic effect on inflammatory bowel disease.
