该发明涉及一般式(I)的生理活性化合物:
R1Z1—Het—L1—Ar1—L2—Y (I)
其中,Het是一个可选择取代的、饱和的、部分饱和的或完全不饱和的含有至少一个来自O、S或N的杂原子的8到10成员的双环环;R1是可选择取代的芳基、杂环芳基、烷基、烯基、炔基、环烷基或杂环烷基;Z1代表直链键、烷基链、NR4、O或S(O)n;L1是一个a—R5—R6—连接,其中R5是烷基、烯基或炔基,R6是直链、环烷基、杂环烷基、芳基、杂芳基二烷基、—C(═Z3)—NR4—、—NR4—C(═Z3)—、—Z3—、—C(═O)—、—C(═NOR4)—、—NR4—、—NR4—C(═Z3)—NR4—、—SO2—NR4—、—NR4—SO2—、—O—C(═O)—、—C(═O)—O—、—NR4—C(═O)—O—或—O—C(═O)—NR4—;L2是一个直链;一个可选择取代的烷基、烯基、炔基、环烯基、环烷基、杂芳基二烷基、杂环烷基或芳基连接;一个—[C(═O)—N(R9)—C(R4)(R10)]p—连接;一个—Z4—R11—连接;一个—C(═O)—CH2—C(═O)—连接;一个—R11—Z4—R11—连接;或一个—L3—L4—L5—连接;Y是羧基或酸生物同位素;以及相应的N-氧化物,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化合物(例如水合物)。
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)相互作用的能力。
