Anilide derivative, production and use thereof

TECHNICAL FIELD
The present invention relates to an anilide derivative or a salt thereof having antagonistic activity on MCP-1 (monocyte chemoattractant protein-1) receptor, production method and use thereof.
BACKGROUND ART
MCP-1 is known to be a monocyte chemotactic factor relating to inflammatory diseases, and belongs to CC chemokine sub-family. MCP-1 is found to express not only from monocyte but also from cardiac muscle cell, blood vessel endothelial cell, fibroblast, chondrocyte, smooth muscle cell, mesangial cell, aveolar cell, T lymphocyte, macrophage, etc. in various pathosis (specifically, angiostenosis, arteriosclerosis, rheumatic arthritis, diabetic microangiopathy, granulomatous inflammation (tuberculosis, sarcoidosis, etc.), solid cancer, diastolic cardiomyopathy (chronic heart failure, etc.), glomerulonephritis, etc.), and MCP-1 deeply relate to crisis and progression these pathosis. Therefore, MCP-1 receptor antagonists are used as a medicament for the treatment and prophylaxis of these pathosis.
So far, there have been only a little reports on low molecule compounds having antagonistic activity on MCP-1 receptor. For example, it is disclosed that aryloxy-propanolamine derivatives being active as .beta.-blocker show weak inhibitory activity on MCP-1 binding to its receptor in JP-A-25756/1995 and that phenylethanolamine derivatives having sympathetic activity and sympatholytic activity show weak inhibitory activity on MCP-1 binding to its receptor in JP-A-25757/1995.
On the other hand, phosphonic acid derivatives having osteogenesis activity is disclosed in JP-A-73476/1996 but there is no description on MCP-1 receptor antagonistic activity.
The present invention is to provide a new anilide derivative or a salt thereof having antagonistic activity on MCP-1 receptor and therapeutic and prophylactic effect on cardiac infarction, myocarditis, cardiomyopathy, chronic heart failure, restenosis after angioplasty, disorder after reperfusion in lung and heart, inflammatory diseases (e.g. arteriosclerosis, arteriosclerosis after heart transplantation, (chronic) rheumatic arthritis, nephritis, etc.), rejection after organ transplantation, fibroid lung, renal insufficiency, diabetic diseases (e.g. diabetes, diabetic nephropathy, diabetic complication, diabetic retinopathy, diabetic retinitis, diabetic microangiopathy, etc.), tumor (e.g. bladder cancer, breast carcinoma, cervical carcinoma, chronic lymphocytic leukemia, chronic myelocytic leukemia, colon carcinoma, multiple myeloma, malignant myeloma, prostatic cancer, lung cancer, stomach cancer, Hodgkin's disease, etc.) infectious diseases (e.g. tuberculosis, invasive staphylococcia, etc.), etc.; production method and use thereof.

To a solution of 4-nitrobenzaldehyde (3.02 g) and 2-aminopyridine (1.88 g) in 1,2-dichloroethane (70 ml) were added triacetoxy sodium boro hydride (5.93 g) and acetic acid (1.14 ml), and the mixture was stirred under nitrogen atmosphere at room temperature for 2 hours and concentrated. To the residue was added sodium bicarbonate solution, and the mixture was extracted with ethyl acetate, washed with brine, dried (anhydrous magnesium sulfate) and concentrated. The residue was purified with silica gel column chromatography (ethyl acetate/hexane=1/1), and to the purified materials were added ethyl acetate/diethylether and 1N hydrochloric acid. The aqueous layer was extracted and washed with diethylether, and to the mixture was added sodium carbonate. The mixture was extracted with ethyl acetate, and the extract was dried (anhydrous magnesium sulfate), concentrated and recrystallized from ethyl acetate/hexane to give 2-[(4-nitrophenyl)methylamino]pyridine (1.63 g) as pale yellow crystals.

REFERENCE EXAMPLE 299
To a solution of nicke l bromide (44 mg) in methanol (4 ml)/THF (4 ml) was added sodium boro hydride (40 mg), and the mixture was stirred. To the mixture was added 2-[(4-nitrophenyl)methylamino]pyridine (0.92 g) and then sodium boro hydride (414 mg), and the mixture was stirred at room temperature for 1 hour. To the mixture was added nickel bromide (44 mg)and sodium boro hydride (454 mg), and the mixture was stirred at room temperature for 2 hours. Insoluble materials were filtered off with sellaite, and to the filtrate was added sodium bicarbonate solution. The mixture was extracted with ethyl acetate and washed with brine. The extract was dried (anhydrous magnesium sulfate) and concentrated, and the residue was purified twice with silica gel column chromatography (ethyl acetate/hexane=1/1) to give 2-[(4-aminophenyl)methylamino]pyridine (369 mg) as pale red solid.
