A compound having the formula (I)
wherein
Ais a phenyl ring unsubstituted or substituted by one to three substituents independently chosen from halogen, CF₃, C₁-C₄ alkyl and C₁-C₄ alkoxy;
R₁is phenyl unsubstituted or substituted by halogen, C₁-C₄ alkyl, C₁-C₄ alkoxy or CF₃; C₅-C₆ cycloalkyl; or a straight or branched C₁-C₆ alkyl group;
Tis a branched or straight C₃-C₅ alkylene chain;
Wis a group -OR or
in which R is hydrogen or C₁-C₄ alkyl; or a pharmaceutically acceptable salt thereof; and wherein when, at the same time A is a phenyl ring unsubstituted or substituted either by C₁-C₄ alkoxy or by one or two substituents chosen from halogen and CF₃ and R₁ is a phenyl ring unsubstituted or substituted by halogen, CF₃ or C₁-C₄ alkoxy; C₅-C₆ cycloalkyl; or C₁-C₆ alkyl, then W is other than a group -OR as defined above,
which is useful as inhibitor of thromboxane A₂ (TxA₂) synthesis.
化合物的化学式为(I),其中A是苯环,未取代或被一个到三个取代基取代,这些取代基独立地选择自卤素、CF₃、C₁-C₄烷基和C₁-C₄烷氧基;R₁是苯环,未取代或被卤素、C₁-C₄烷基、C₁-C₄烷氧基或CF₃取代;C₅-C₆环烷基;或是直链或支链的C₁-C₆烷基;T是支链或直链的C₃-C₅烷基链;W是-OR基团,其中R是氢或C₁-C₄烷基;或其药学上可接受的盐;当A同时是未取代或被C₁-C₄烷氧基或由卤素和CF₃中选择的一个或两个取代基取代的苯环,且R₁是未取代或被卤素、CF₃或C₁-C₄烷氧基取代的苯环、C₅-C₆环烷基或C₁-C₆烷基时,则W不是上述定义的-OR基团,该化合物可用作凝血素A₂(TxA₂)合成的抑制剂。
