A novel butadiene derivative of the formula:
wherein Ring A is heterocycle, or benzene being optionally substituted by lower alkyl, alkoxy, nitro, hydroxy, substituted or unsubstituted amino or halogen, Ring B is heterocycle, or benzene being optionally substituted by lower alkoxy, lower alkylenedioxy or di-lower alkylamino, R1 and R2 are each H or lower alkyl, one of —COR32 and —COR42 is carboxyl, and the other is carboxyl being optionally esterified, or the corresponding amide or pyrrolidine derivatives, or a pharmaceutically acceptable salt thereof. Said compounds show excellent PAI-1 inhibitory activity and are useful in the prophylaxis or treatment of various thromboses such as myocardial infarction, intra-atrial thrombus in atrial fibrillation, cerebral infarction, angina pectoris, stroke, pulmonary infarction, deep venous thrombus (DVT), disseminated intravascular coagulation syndrome (DIC), diabetic complications, restenosis after percutaneous transluminal coronary angioplasty (PTCA), etc.
一种新颖的丁二烯衍生物,其结构式为:其中,环A为杂环或苯环,可选择性地被低级烷基、烷氧基、硝基、羟基、取代或未取代的氨基或卤素取代;环B为杂环或苯环,可选择性地被低级烷氧基、低级亚烷基二氧基或二低级烷基氨基取代;R1和R2各自为氢或低级烷基;其中—COR32和—COR42之一为羧基,另一为可选择性酯化的羧基,或相应的酰胺或吡咯烷衍生物,或其药学上可接受的盐。这些化合物表现出优异的PAI-1抑制活性,可用于预防或治疗各种血栓性疾病,如心肌梗死、心房颤动中的心房内血栓、脑梗死、心绞痛、中风、肺栓塞、深静脉血栓(DVT)、弥散性血管内凝血综合征(DIC)、糖尿病并发症、经皮冠状动脉腔内成形术(PTCA)后的再狭窄等。
