TECHNICAL FIELD

[0002] The present invention relates to a VLA-4 inhibitory drug that has a novel cyclohexanecarboxylic acid skeleton and is orally administrable.

BACKGROUND ART

[0003] Leukocyte is well known to play a critical role in inflammatory reactions that could be caused by microbial intrusion, the damaged tissue or the like. It is also known that leukocytes usually circulate in the blood vessel and, once the tissue is inflamed, leukocytes are infiltrated into the inflamed tissue by passing through the blood vessel wall adjacent to the such a tissue. This infiltration is found to be associated with the integrins expressed on the surface of a leukocyte cell.

[0004] An integrin is composed of a heterodimer of glycoprotein in which two noncovalently associated subunits (i.e., .alpha.-subunit and .beta.-subunit) coalesce with each other. So far, at least 16 species are known to be included in the family of .alpha.-subunit, while at least 9 species are known to be included in the family of .beta.-subunit, and thus these subunits form such a large family, respectively. An integrin ".alpha.4.beta.1", which is known also as VLA-4 (very late antigen-4), is expressed on the cell surface of leukocytes such as monocytes, lymphocytes, eosinophiles, basophiles, mast cells and macrophages (Non-Patent Document 1). VCAM-1 (vascular cell adhesion molecule-1), as well as extracellular proteins such as fibronectin (FN), are known as the ligands of .alpha.4.beta.3 (Non-Patent Document 2).

[0005] Among the effects obtain able by inhibiting the adhesion between VLA-4 and VCAM-1 are an anti-inflammatory action using an anti-.alpha.4 monoclonal antibody (Non-Patent Document 3), inhibitory action against bronchial hyperactivity at the time of antigen induction and inhibitory action against leukocyte infiltration into bronchioalveolar secretion in a guinea pig pulmonary inflammation model using an anti-.alpha.4 antibody (Non-Patent Document 4).

[0006] Also, there is a report focusing on a suppressive effect on inflammatory diseases by inhibiting the adhesion between VLA-4 and FN (Non-Patent Document 5). According to this report, an artificial CS-1 (connecting segment-1) tripeptide derivative [Phenylacetic acid-Leu(L)-Asp (D)-Phe(F)-d-Pro(d-P)-amide] in the amino acid sequence of CS-1, which is known as a region where binding of FN to VLA-4 occurs, suppressed a rejection reaction in rabbit heart transplantation.

[0007] The results of these researches suggest that if the cellular adhesion between VLA-4 and VCAM-1 and/or FN is effectively inhibited, it would be of great use as a means for the treatment of inflammatory diseases. However, any of the low molecular weight compounds, known as having a VLA-4 inhibitory action (Patent Document 1 to Patent Document 7, and Non-Patent Document 6), has yet to be used as a medicament.

[0008] Although an orally administrable agents is regarded as preferable in teaching inflammatory diseases, it is also known that most of such compounds have poor oral absorbability and tend to suffer a short retention time in blood. Hence, there are only a few, if any, reports showing that such a sufficient effect has been obtained by oral administration.

DISCLOSURE OF THE INVENTION

Problems to be Solved by the Invention

[0022] In order to develop an orally administrable VLA-4 inhibitory drug, it is necessary to improve its oral absorbability and its retention durability in blood alike.

[0023] Enhancement of oral absorbability of a compound requires an appropriate increase in the lipophilicity of the compound. However, if lipophilicity is too high, there is a risk so serious that non-specific binding of the compound to serum proteins (i.g., serum albumin) sharply increases, so that it becomes impossible for the compound to sufficiently bind to a target protein, thereby hampering the drug efficacy. Furthermore, when lipophilicity is increased, this leads to a decrease of the solubility in water, and provokes a decrease in oral absorbability adversely. Thus, many problems are likely to arise, such as that the dose dependency of the drug cannot be secured on demand, and that the efficacy could vary widely depending on individual differences.

[0024] Therefore, in order to develop an orally administrable VLA-4 inhibitory drug, it is important to address the following four factors, i.e., 1) adequate lipophilicity, 2) adequate retention in blood, 3) adequate binding affinity to serum proteins, and 4) good water solubility.

[0025] An object of the present invention is to solve such problems, and to obtain a VLA-4 inhibitory drug having good oral absorbability and exhibiting sufficient anti-inflammatory effects through oral administration.

Subsequently, this was dissolved in DMF (10 mL), and [2,5-dichloro-4-[(1-methyl-1H-indol-3-ylcarbonyl)amino]phen yl]acetic acid (167 mg, 0.442 mmol), EDC-HCl (127 mg, 0.663 mmol), HOBt (90 mg, 0.663 mmol) and triethylamine (0.61 mL, 4.42 mmol) were added thereto. The mixture was stirred for 12 hours. The reaction liquor was diluted with ethyl acetate (200 mL), washed with saturated brine (2.times.100 mL), and dried over anhydrous sodium sulfate, and then the solvent was concentrated under reduced pressure. Then, DMF was removed by boiling azeotropically with toluene. The obtained residue was purified by column chromatography using silica gel [chloroform-ethyl acetate (4:1) to chloroform-ethyl acetate-methanol (5:5:1)], to obtain the title compound (260 mg, 83%) as an oily matter.

[1743] Bis-(2-oxoethyl)carbamic acid benzyl ester (0.90 g, 3.81 mmol) and 1-methyl-cyclopropylamine (0.41 g, 3.81 mmol) were dissolved in dichloroethane (20 mL), and sodium triacetoxyborohydride (3.23 g, 15.24 mmol) was added thereto. The mixture was stirred for 4 days at room temperature. A saturated aqueous solution of sodium hydrogen carbonate (20 mL) was added to the reaction liquor, and the mixture was stirred for 20 minutes, and then extracted with methylene chloride. The extract was washed with saturated brine, and dried over anhydrous sodium sulfate, and then the solvent was concentrated under reduced pressure. The obtained residue was purified by flash chromatography (Flash Chromatography System from Biotage AB, column size: 25S, n-hexane/ethyl acetate=5/1 to ethyl acetate), to obtain the title compound (509 mg, 49%) as an oily matter.

##STR00336##

[2091] 1H-indole-3-carboxylic acid (3.00 g, 18.6 mmol) was suspended in 1,2-dichloroethane (15 mL), and oxalyl chloride (2.42 mL, 25.38 mmol) was added dropwise. To this reaction liquor, a catalytic amount of DMF (one drop) was added, and the reaction liquor was stirred for one hour at room temperature. The solvent of the reaction mixture was distilled off under reduced pressure, to obtain 1H-indole-3-carboxylic acid chloride as a solid. The obtained acid chloride was suspended in 1,2-dichloroethane (20 mL), and (4-amino-2,5-dichlorophenyl)acetic acid ethyl ester hydrochloride (4.82 g, 16.92 mmol) was added thereto. The mixture was heated to reflux for 18 hours with stirring. The reaction mixture was left to cool naturally to room temperature, and then the solvent was distilled off under reduced pressure. The obtained solids were dissolved in chloroform (100 mL), washed with a saturated aqueous solution of sodium hydrogen carbonate and water, and dried over anhydrous sodium sulfate, and then the solvent was distilled off under reduced pressure. The obtained solids were collected by filtration using hexane, to obtain [2,5-d]chloro-4-[(1H-indol-3-ylcarbonyl)amino]phenyl]acetic acid ethyl ester (5.95 g, 90%) as a solid. This compound was used in the subsequent reaction without performing further purification.

[2092] This [2,5-d]chloro-4-[(1H-indol-3-ylcarbonyl)amino]phenyl]acetic acid ethyl ester (5.7 g, 14.57 mmol) was added to THF (50 mL) and ethanol (30 mL), and a 0.25N-aqueous solution of sodium hydroxide (120 mL) was added thereto. The mixture was stirred for 15 hours at room temperature, and then for one hour at 60.degree. C. The reaction mixture was left to cool naturally to room temperature, and then 1N--HCl (32 mL) was added thereto while stirring the reaction mixture under ice cooling. Precipitated crystals were collected by filtration under reduced pressure, washed with water, and then dried, to obtain the title compound (4.25 g, 80%) as a solid.

In Vitro Evaluation of Substance Under Test

[2097] CHO cells which forcibly expressed h.alpha..sub.4 and .beta..sub.1 integrins through transfection thereof, were inoculated into a Costar 3599 plate (3.times.10.sup.4 cells/100 .mu.l/well), and cultured for two days. The cells in the wells were washed two times with buffer A*, and then Eu.sup.3+-hVCAM-1 D1D7-IgG diluted with assay buffer** to 2 nM was added in an amount of 50 .mu.l/well. The substance under test diluted with 2% DMSO-assay buffer (in the co-presence or absence of 6% human serum albumin) was added in an amount of 50 .mu.l/well (adding separately diluted solution to the wells for performing Scatchard analysis), the contents were stirred for 5 minutes with a plate mixer, and then the plate was left to stand still for one hour at room temperature. The binding inhibitory activity in the presence of human serum albumin (HSA) was examined by diluting the specimen with 2% DMSO-assay buffer containing 6% HSA (SIGMA Corp., c/n A-1653), and adding the resultant (HSA final concentration 3%). After 30 to 60 minutes of the addition of specimen, the plate contents were washed 4 times with buffer A at 4.degree. C., an enhancing reagent (DELFIA SA) was added in an amount of 100 .mu.l/well, and the plate was shaken for 5 minutes using a plate mixer. Subsequently, the fluorescence intensity was measured with a time-resolved fluorometer (DELFIA Wallac). The IC.sub.50 of the substance under test (the concentration for 50% inhibition of the binding between CHO cells and Eu.sup.3+-hVCAM-1 D1D7-IgG) was determined from the binding rate obtained from the calculating expression of [(F.sub.T-F.sub.NS)-(F.sub.I-F.sub.NS)]/[(F.sub.T-F.sub.NS)].times.100. Here, F.sub.T represents the fluorescence intensity of a well not containing the substance under test; F.sub.NS represents the fluorescence intensity of a well not containing the substance under test and hVCAM-1 D1D7-IgG; and F.sub.I represents the fluorescence intensity of a well containing the substance under test. The Kd value which represents the strength of binding, and B.sub.max (maximum binding amount) were estimated to be in the range of 0.06 to 20 nM according to the Scatchard analysis method. The evaluation results of the Ki value of the substance under test, and of the IC.sub.50 value in the presence of 3% HSA are presented in Tables 2 to 7.

In Vivo Evaluation of Substance Under Test

[2103] Test for eosinophile infiltration in mice actively sensitized with ascaris (antigen to pig roundworm):

[2104] It has been reported that infiltration of eosinophilic cells is induced by active sensitization with ascaris {Int. Arch. Immuno., 108, 11-18 (1995)}. An evaluation of the compounds under test was performed according to the evaluation method described herein. The substance under test was orally administered in an amount of 5 mg/kg, two times a day. The total cell count and the eosinophile count in BALF of 48 hours after sensitization were calculated, and the effects were determined by comparing with the group not administered with the substance under test. The results are presented in Table 8.

[2105] The results of Table 8 will be discussed. In the pathological control group in which mice were sensitized with ascaris, the infiltrated eosinophile count in BALF after 48 hours increased by 2.55.times.10.sup.5 cells on the average, compared to the normal control group in which mice were sensitized with saline (physiological saline). On the other hand, in the ascaris-sensitized group administered with mouse anti-VLA-4 antibody (s.c. administration of two times a day), the infiltrated eosinophile count in BALF was 1.13.times.10.sup.5 cells on the average, and a significant effect of decreasing the infiltrated eosinophile count by 56% was shown, compared to the pathological control group.

[2106] Likewise, in the group of oral administration (5 mg/kg, two times a day) of compound A (representative compound of WO 02/053534), a significant effect of decreasing the infiltrated eosinophile count by 57% was shown, compared to the pathological control group, and the suppressive effects were about the same as those of the mouse anti-VLA-4 antibody.

[2107] In the group orally administered with the Example compounds of the present invention, significant effects of decreasing the infiltrated eosinophile count by 44% to 70% were shown, compared to the pathological control group. Thus, the suppressive effects of the Example compounds of the present invention were equal to the suppressive effects of the group administered with the mouse anti-VLA-4 antibody and the compound A.
