Description

BY, KG, KZ, - • BG, cp, CY, 1E.1S, IT. LT, OAPI (BF, BJ MR, NE, SN, * tt &H? #S: NOVEDOUS DERIVATIVES OF FEN1LALAN1NA FIELD OF THE INVENTION The present invention relates to novel phenylalanine derivatives and the use of phenylalanine derivatives as medicines. The present invention also relates to compounds useful as therapeutic agents or preventive agents of inflammatory diseases in which the adhesion process dependent on integrin a 4 participates in the pathology. It was reported that integrins 4 participate in rheumatoid arthritis, inflammatory bowel disease (including Crohn's disease and ulcerative colitis), systemic lupus erythematosus, multiple sclerosis, Sjögren's syndrome, asthma, psoriasis, allergy, diabetes mellitus, cardiovascular diseases, sclerosis arterial pressure, restenosis, tumor proliferation, tumor metastasis and transplant rejection. The compounds of the present invention which have an antagonistic effect on integrins a 4 are useful as therapeutic agents or preventive agents for the diseases described above. In addition, it has been reported that integrins at 4 have the potential to participate in preeclampsia, cerebral ischemic disorders (including cerebral infarction), systemic sclerosis, ankylosing spondylitis, psoriatic arthritis, sarcoidosis, giant cell arteritis, uveitis, fibroid lung, lung disease chronic obstructive disease, osteoarthritis, Alzheimer's, spinal cord injury, traumatic brain injury, primary sclerosing cholangitis, liver cirrhosis caused by hepatitis C, chronic active hepatitis, sacroiliitis, ankylosing spondylitis, episcleritis, iritis, uveitis, erythema nodosum, pyoderma gangrenosum and autoimmune hepatitis. The compounds of the present invention are also useful as therapeutic agents or preventive agents for the diseases described above. In addition, the compounds of the present invention are useful as therapeutic agents or preventive agents not only for the aforementioned diseases but also for diseases in which intakes to 4 are impotent to participate in the pathology. The present invention also relates to the methods for the production of the novel phenylalanine derivatives mentioned above and the intermediates of the synthesis thereof.
BACKGROUND OF THE INVENTION In inflammatory reactions, it is generally understood that when a microorganism invades a tissue or when the tissue of the injured, the leukocytes play an important role for the exclusion of the microorganism or for the repair of the injured tissue. It is also widely understood that in such cases, usually leukocytes in Circulation in the blood must pass through the vascular wall and must again supply the injured tissue. It has been elucidated that the infiltration of leukocytes from the blood vessel into the tissue is carried out by integrin molecules which are a group of heterodimeric proteins that are expressed in leukocytes. The integrin molecules are classified in at least 8 subfamilies (subfamilies ß 1 to ßd) depending on the β chains of them. Typical known subfamilies are the β1 and β3 subfamilies involved in the adhesion of cellular ingredients to the extracellular matrix such as collagen and fibronectin; subfamily ß 2 involved in cell-cell adhesion in the immune system; and subfamily ß 7 which mainly participates in the infiltration of leukocytes into mucosal tissues (non-patent literature 1). As for the integrins a 4 described above, two types of molecules thereof are known. There is the molecule VLA-4 (very late antigen 4) that belongs to the subfamily ß 1 and that includes the chain 4 ß 1 and the molecule LPAM-1 (adhesion molecule HEV of the Peyer's plate of lymphocyte-1) that belongs to subfamily ß 7 and comprising the chain at 4 ß 7. Usually the majority of circulating leukocytes in the blood have only a few adhesion affinities for vascular endothelial cells and can not move out of blood vessels . However, the lymphocytes that mainly comprise the T cells and the B cells are able to move out of the blood vessels through a phenomenon called lymphocyte self-direction where these move from the blood to the lymphoid tissue through the wall of the blood vessels and subsequently these can return to the blood through the lymphatic vessels under physiological conditions. It is known that LPAM-1 molecules participate in lymphocyte autodirection towards the lymphoid tissue of an intestinal tract such as Peyer's plaque (non-patent literature 2). On the other hand, when inflammation occurs, vascular endothelial cells are activated by cytokines and chemokines released from inflamed tissue, the expression of a group of cell surface antigens (adhesion molecules) involved in the adhesion of the leukocytes to the vascular endothelial cells, and many leukocytes infiltrate out of the blood vessel into the inflamed tissue through the adhesion molecules. Since cell surface antigens in vascular endothelial cells participate in the adhesion of leukocytes, it is known that E-selectin (adhesion molecule that participates mainly in the adhesion of neutrophils), ICAM-1 and VCAM-1 which mainly participate in the adhesion of lymphocytes, and MAdCAM-1 which mainly participates in the adhesion of lymphocytes in the lymphoid tissue of an intestinal tract such as Peyer's plaque (non-patent literature 1). It was reported that in those adhesion molecules, VCAM-1 acts as a ligand for both VLA-4 and LPAM-1 and that MAdCAM-1 acts as the ligand for LPAM-1. As a ligand of both VLA-4 and LPAM-1, fibronectin is also known, which is a type of extracellular matrix (non-patent literature 1). The subfamily of β 1 integrin to which VLA-4 belongs comprises at least 6 integrins (VLA-1 to VLA-6) using extracellular matrices such as fibronectin, collagen and laminin as the ligands. Many of the integrins use extracellular matrices as ligands, such as VLA.5, the subfamily β3 and the subfamily β5, recognize the sequence arginine-glycine-aspartic acid (RGD) in fibronectin, vitronectin, tenascin and osteopontin . On the other hand, in the interaction of VLA.4 and fibronectin, the RGD sequence participates only as a CS.1 peptide segment comprising leucine-aspartic acid-valine (LDV) as the participating core sequence (non-patent literature 3) . Clemens et al. found a sequence similar to the LDV in the amino acid sequence of VCAM-1 and MAdCAM-1. It has been elucidated that a variant obtained by partially modifying the CS.1-like sequence of the molecules VCAM.1 and MAdCAM.1 can not interact with VLA-4 or with LPAM-1 (non-patent literatures 4 to 7) . Therefore, it was found that the sequence similar to CD-1 is important for the interaction of VLA-4 / LPAM-1 and VCAM-1 / MAdCAM-1. It was also reported that the cyclic peptide having the structure similar to CS-1 is antagonistic to both the interaction of VLA-4 or LPAM-1 with VCAM-1, MAdCAM or the peptide CS-1 (non-patent literature 8). The aforementioned facts indicate that all interactions of integrin to 4 and VCAM-1. MAdCAM-1 or fibronectin can be blocked by the use of an integrin ce 4 antagonist (the term "antagonist" of integrin at 4"in the specification indicates an antagonistic substance to integrin a4ß1 and / or a4ß7.) It is also known that the expression of VCAM-1 in vascular endothelial cells is caused by inflammatory factors such as LPS, TNF -a or IL-1 and that when inflammation occurs, the infiltration of leukocytes from the blood vessel into the tissue is carried out by the adhesion mechanism of VLA-4A CAM-1 (non-patent literature 9 a 11) Because VLA-4 is expressed on the surface of activated lymphocytes, monocytes, eosinophils, mast cells and neutrophils, the adhesion mechanism of VLA-4V / CAM-1 plays an important role for the infiltration of those cells towards inflamed tissue It was reported that VLA-4 is expressed in various sarcoma cells such as melanoma cells, and it was also elucidated that the adhesion mechanism of VLA-4 / VCAM-1 participates in the metastasis of these tumors. By investigating the expression of VCAM-1 in various pathological tissues, it became evident that the adhesion mechanisms of this VLA-4A / CAM-1 participate in various pathological stages. That is, it was reported that in addition to the activated cells of the vascular endothelium, the expression of VCAM-1 is increased in inflamed tissues in patients with autoimmune diseases such as in the rheumatoid synovium (literature no 12 and 13), lungs and epithelium of the respiratory tract in asthma (non-patent literature 14) and allergic diseases (non-patent literature 15), systemic lupus erythematosus (non-patent literature 16), Sjogren's syndrome (non-patent literature) patent 17), multiple sclerosis (non-patent literature 18) and psoriasis (non-patent literature a 19); atherosclerotic plaques (non-patent literature 20), intestinal tissues of patients with inflammatory bowel diseases such as Crohn's disease and ulcerative colitis (non-patent literatures 21 and 22), inflamed tissue of the Langerhans islet of patients with diabetes ( non-patent literature 23) and implants during the rejection of heart or kidney transplantation (non-patent literatures 24 and 25). The adhesion mechanism of VLA-4A CAM-1 participates in these various diseases. There are many reports that show that in vivo administration of the VLA-4 or VCAM-1 antibody was effective in the improvement of the diseases of the animal models with those inflammatory diseases. Specifically, Yednock et al. and Barón et al. reported that in vivo administration of an antibody against integrins to 4 was effective in controlling the incidence ratio or in the control of encephalomyelitis in experimental autoimmune encephalomyelitis models, for example multiple sclerosis models (non-literature Patent 26 and 27). Zeidler et al. reported that in vivo administration of an antibody against integrin a 4 was effective in controlling the incidence ratio of arthritis by mouse collagen (rheumatoid models) (non-patent literature 28). The therapeutic effect of an antibody against integrin a 4 in asthma models was reported by Abraham et al. and SAgara et al. (Literatures not of patent 21 and 30). The effect of an antibody against the Integrin at 4 in inflammatory bowel disease models was reported by Podolsky et al. (non-patent literature 31). The effect of an antibody against integrin was reported to 4 and that against. VCAM antibody in models of insulin-dependent diabetes by Barón et al. (non-patent literature to 32). It was evident with baboon models that restenosis of a blood vessel after angioplasty is carried out because arteriosclerosis can be inhibited by administration of the integrin antibody to 4 (non-patent literature 33). It was also reported that the integrin a 4 or the VCAM antibody is effective in inhibiting the rejection of an implant or in the inhibition of cancer metastasis (non-patent literatures 34 and 35). The therapeutic effect of an antibody against V.CAM-1 in inflammatory bowel disease models was reported by Sans et al. (non-patent literature 44). As described above, unlike VCAM-1, MAdCAM-1 which is a ligand of LPAM-1 is constitutively expressed in elevated endothelial venules (HEV) in the intestinal mucosa, mesenteric lymph nodes, Peyer's plaque and spleen and participates in the self-direction of mucosal lymphocytes. It is also known that the mechanism of adhesion by LPAM-1 / MAdCAM-1 not only has physiological roles in the self-direction of lymphocytes but also participates in some pathological processes. Briskin et al reported an increase in the expression of MAdCAM-1 in inflamed regions in intestinal tracts of patients with inflammatory bowel diseases such as Crohn's disease and Ulcerative colitis (non-patent literature 36). Hanninen et al. reported that induction of expression is observed in inflamed tissue of the Langerhans islet of the NOD mouse which is a model of insulin-dependent diabetes (non-patent literature 37). The fact that the adhesion mechanism by LPAM-1 / MAdCAM participates in the progression of diseases is evident from the fact that the conditions of the mouse models with inflammatory bowel disease (non-patent literature 38) and the NOD mouse models described above are improved by the live administration of the antibody to MAdCAM or to the antibody to β-7 integrin (non-patent literatures 39 and 40). The aforementioned facts indicate that the possibility of using the blocking of the adhesion mechanism by VLA-4? / CAM-1, LPAM-1? / CAM-1 or LPAM-1 / MAdCAM-1 by a suitable antagonist is effective in the treatment of the chronic inflammatory diseases described above. With respect to the therapeutic effects of the appropriate antagonist (s), these can be ensured by the animal models described in the aforementioned literatures or the other literatures such as non-patent literature 45 and 46. The use of the antibody in against VLA-1 as the VLA-4 antagonist is described in patent literatures 1 to 4. Peptide compounds such as VLA-4 antagonists are described in patent literature 5 to 8. Useful amino acid derivatives such as VLA-4 antagonists are described in patent literature 9 to 13. The integrin inhibitor a 4 of low molecular weight which can be administered orally is described in patent literatures 14 and 15.

First, an amide (S-8) can be obtained by reacting the amine (S-6) with a carboxylic acid from which an amino group in the ortho position activated by the use of a condensing agent such as DIC and, if it is necessary, a suitable additive such as HOAt or HOBt in an organic solvent such as DMF, NMP or dichloromethane. Subsequently, an amide (S-8) is formed in cycle by the same process mentioned above to obtain the quinazolinedione (S-9). The substituents R 'and R "' in the formulas (S-7) to (S-9) are groups which are derived from benzoic acid derivatives used in the aforementioned reaction, these are R1 'or -XrN (R12 ) R13 described in formula (1), or groups which can be converted to R11 or X N (R12) R13 at any stage of the synthesis. < S- «(S-105) In the formula (S-10), compounds can be obtained wherein R" is represented by a methyl group by the reaction of Mitsunobu with the quinazolinedione (S-9) using methanol, diisopropylazodicarboxylic acid and The similar ones can be obtained by the reaction of methyl iodide under the existence of a base such as potassium carbonate.
The ester (S-10) thus obtained is cleaved from a resin under suitable conditions to obtain a carboxylic acid (S-11). For example, when the Wang resin is used, in the ester (S-10), each of Q, R1, R "and R '" are converted, if necessary, to 2-Yn-6- Y? 2 -Ph-CO, -XrN (R12) R13, a methyl group or R ^, or groups which can be converted to 2-Yp-6-Y12-Ph-CO, -XrN (R? 2) Ri3, a group methyl or R-i 'under the conditions of removal of the resin. Subsequently, the ester (S- ) is treated with an acid solution that includes TFA (trifluoroacetic acid) to obtain a solution of the carboxylic acid (1: R1 = OH) wherein, in the formula (1), R1 is represented by a hydroxyl group. In addition, the pure carboxylic acid (1: R1 = OH) can be obtained by applying well known isolation and purification methods such as concentration, extraction, crystallization, column chromatography, HPLC and recrystallization to the carboxylic acid thus obtained (1: R1 = OH). In addition, the carboxylic acid (1: R1 = OH) can also be obtained by applying the methods for solid phase synthesis to the liquid phase method where the appropriate protective group is selected and well-known methods of isolation and purification are used. . In the carboxylic acid (S-11), each of Q, R ', R "and R'" represent 2-Yn-6-Y-? 2-Ph-CO, -XrN (R12) R? 3, a methyl group or R ^, or groups which can be converted to 2-Yn-6 ?? 2-Ph-CO, -XrN (R- | 2) R? 3, a methyl group or R? ' in subsequent processes. The carboxyl group in the formula (S-11) can be converted to the group -CO-R11 (wherein R11 represents an alkoxy group) by a well-known esterification. More specifically, the methods are as follows. The carboxyl group is treated with a suitable alcohol under the conditions of dehydration under an acid catalyst; if necessary, it is treated with O-alkylating agents such as an alkyl halide under the existence of a base or an acid; if necessary, it is treated with an adequate alcohol under the existence of a base, after the conversion to the acid halide with thionyl chloride and the like; more specifically, it is treated with, for example, ethyl chloroformate under the existence of a base to convert it to acid anhydride. Subsequently, if necessary, the substance of the reaction was treated with a suitable alcohol under the existence of a base. Further, if necessary, it was also treated with a suitable alcohol under the existence of a condensing agent such as dicyclohexylcarbodiimide and a catalyst such as dimethylaminopyridine. After these processes, the compounds of the present invention (1: R1 is an alkoxy group) can be obtained by the conversion of Q, R ', R "and R'", if necessary. In formula (1), for example, a compound of (S-15) wherein Xi represents CH 2 can be synthesized as follows. In the formula, R11a represents R11 or functional groups which can be converted to R11 at any stage of the synthesis.
A nitro compound (S-12), which is a raw material, can be obtained, for example, by the synthesis process such as that of (S) -2- (2,6-dichlorobenzoylamino) -3-hydropropyl ester. - (4-nitrophenyl) propionate in process 1 of reference example 4. The nitro compound (S-12) is reduced to an aniline compound by reaction with SnCl 2, the hydrogenation reaction in the presence of catalysts metals, and Similar. More specifically, the corresponding aniline compounds can be obtained, for example, by the synthesis process such as that of the (S) -2- (2,6-dichlorobenzoylamino) -3- (4-aminophenyl) propionic acid isopropylester in process 2 of reference example 4. After the condensation thus obtained, the compounds of aniline and an anthranilic acid substituted with Xa (Xa represents a halogen atom, a triflate group and the like) by the use of an agent (s) ) suitable condenser, cycle formation is carried out by reagents such as CDl (carbonyldiimidazole), ethyl chloroformate and triphosgene to obtain (S-13). Other methods for obtaining (S-13) is as follows: the aforementioned aniline compounds are reacted with 2-nitrobenzoic acid chloride substituted with Xa under the existence of a suitable base; and subsequently, a nitro group is reduced by SnCl 2, the hydrogenation reaction in metal catalysts, and the like and formed in cycle by the reagents such as CD 1, ethyl chloroformate and triphosgene. The other additional method for obtaining (S-13) is as follows: The urea linkage is formed between the above-mentioned aniline compounds and the ester of an anthranilic acid substituted with Xa by the use of CDl, ethyl chloroformate, triphosgene and the like; and subsequently, if necessary, the reaction mixture is cycled by reaction with a suitable base. Next, R14 is introduced by methods such as reaction of the compound (S-13) with alkyl halide under the existence of a suitable base, and the reaction of Mitsunobu using alcohol. Subsequently, Xa is converted to a carboxylic acid by, for example, a conversion reaction using a palladium and carbon monoxide catalyst. The carboxylic acid is converted to an alcohol compound (S-14, Xb = OH) by the method such as the reactive reaction via mixed acid anhydride. In addition, Xb is converted to a residual group (Xb = a halogen group, a triflate group, a mesylate group, a tosylate group, etc.) using a suitable acid halide, sulfonium halide, thionyl halide, phosphoryl halide and the Similar. Subsequently, the substitution reaction is carried out using a suitable substituted amine to obtain the objective compound (S-15).
