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).
该发明涉及公式(I)的生理活性化合物:
其中:
R1是氢,卤素,羟基,较低烷基或较低烷氧基;
X1,X2和X6独立地表示N或CR10;
而X3、X4和X5中的一个表示CR11,其他的独立地表示N或CR10;
其中,R10是氢,氨基,卤素,羟基,较低烷基,较低烷氧基,较低烷基硫基,较低烷基亚砜基,较低烷基磺酰基,硝基或三氟甲基;
R11表示一个基团—L1—Ar1—L2—Y;
以及这些化合物的相应N-氧化物、它们的前药;和这些化合物及它们的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物特性,特别是调节VCAM-1和纤维连接蛋白与整合素VLA-4(α4β1)相互作用的能力。
