The invention is directed to physiologically active compounds of formula (I):
wherein one of A1, A2 and A3 represents NR2 and the others represent C(R3)(R4); R1 represents R5Z1—Het— or R6N(R7)—C(═O)—NH—Ar2—; Ar1 represents aryldiyl or heteroaryldiyl; L1 represents a —R12-R13— linkage (where R12 is a direct bond or an alkylene chain, an alkenylene chain or an alkynylene chain and R13 is a direct bond, cycloalkylene, heterocycloalkylene, aryldiyl, heteroaryldiyl, —C(═Z3)—NR11—, —NR11—C(═Z3)—, —Z3—, —C(═O)—, —C(═NOR11)—, —NR11—, —NR11—C(═Z3)—NR11—, —SO2—NR11—, —NR —SO2—, —O—C(═O)—, —C(═O)—O—, —NR11—C(═O)—O— or —O—C(═O)—NR11—); and their prodrugs, and pharmaceutically acceptable salts and solvates of such compounds and their 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).
本发明涉及式(I)的生理活性化合物:其中A1,A2和A3中的一个代表NR2,其余代表C(R3)(R4); R1代表R5Z1-Het-或R6N(R7)-C(═O)-NH-Ar2-; Ar1代表芳基二基或杂芳基二基; L1代表-R12-R13-连接(其中R12是直接键或烷基链,烯基链或炔基链,R13是直接键,环烷基,杂环烷基,芳基二基,杂芳基二基,-C(═Z3)-NR11-,-NR11-C(═Z3)-,-Z3-,-C(═O)-,-C(═NOR11)-,-NR11-,-NR11-C(═Z3)-NR11-,-SO2-NR11-,-NR-SO2-,-O-C(═O)-,-C(═O)-O-,-NR11-C(═O)-O-或-O-C(═O)-NR11-);以及其前药和这些化合物及其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学特性,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。
