2-PYRIDYL-SUBSTITUTED IMIDAZOLS AS ALK5 AND/OR ALK4 RECEPTOR INHIBITORS

FIELD: chemistry. ^ SUBSTANCE: invention concerns new compounds of formula I or its pharmaceutically acceptable salts: , where R1 is phenyl group optionally substituted by substitutes selected out of halogen atom, -O-C1-6-alkyl; or R1 is phenyl condensed with aromatic or non-aromatic 5-7-member ring where the ring can optionally include up to three heteroatoms selected independently out of N, O and S; R2 is hydrogen, -O-C1-6-alkyl, -C1-6-alkyl or halogen atom; R3 is C1-6-alkyl, -(CH2)P-NO2, -(CH2)p-NR4R5, -(CH2)P-CONHOH, -(CH2)p-CN, -(CH2)P-CO2H, -(CH2)p-CO2R4, -(CH2)P-CONR4R5, -(CH2)p-OR4, -(CH2)p-NHCOR4 or -(CH2)p-NHSO2R4; R4 and R5 are independently hydrogen or C1-6-alkyl; p is 0, 1, 2, 3 or 4; X is C1-10-alkylene group; one of A1 and A2 is nitrogen atom, while the other is NR7; and R7 is hydrogen atom or OH-group. Also invention concerns pharmaceutical composition, method of TGF-beta and/or activine signal transit route inhibition, method of reduction of excessive exocellular matrix accumulation for mammals, method of tumour cell metastasis inhibition for mammals, method of treatment of cancer neoplasm caused by TGF-beta superexpression by TGF-beta signal transit route inhibition for mammals, method of disease treatment, and method of thrombosis inhibition for mammals. ^ EFFECT: new compounds with useful biological properties. ^ 16 cl, 19 ex, 2 tbl, 8 dwg
