The invention is directed to physiologically active compounds of formula (I):
wherein:
R1 is hydrogen, halogen, hydroxy, lower alkyl or lower alkoxy;
X1, X2 and X6 independently represent N or CR10; and
one of X3, X4 and X5 represents CR11 and the others independently represents N or CR10;
where R10 is hydrogen, amino, halogen, hydroxy, lower alkyl, lower alkoxy, lower alkylthio, lower alkylsulphinyl, lower alkylsulphonyl, nitro or trifluoromethyl; and R11 represents a group —L1—Ar1—L2—Y; and the corresponding N-oxides, and their prodrugs; and pharmaceutically acceptable salts and solvates of such compounds and their N-oxides and prodrugs. Such compounds have valuable pharmaceutical properties, in particular the ability to regulate the interaction of VCAM-1 and fibronectin with the integrin VLA-4 (&agr;4&bgr;1).
本发明涉及具有下式(I)的生理活性化合物:其中:R1是氢,卤素,羟基,低碳基或低烷氧基;X1,X2和X6独立地表示N或CR10;并且X3、X4和X5中的一个表示CR11,其余的独立地表示N或CR10;其中R10是氢,氨基,卤素,羟基,低碳基,低烷氧基,低烷硫基,低烷基硫醇基,低烷基磺酰基,硝基或三氟甲基;R11表示一个基团-L1-Ar1-L2-Y;以及相应的N-氧化物和它们的前药;以及这些化合物及其N-氧化物和前药的药学上可接受的盐和溶剂。这些化合物具有有价值的药理特性,特别是调节VCAM-1和纤维连接蛋白与整合素VLA-4(α4β1)的相互作用的能力。
