studies of these potent antagonists revealed that the thienyl ring, the (E)-acrylic acid, and the imidazole ring in addition to the two acid groups were important for high potency. Also, overlay comparisons of the parent diacid with both angiotensin II and a representative biphenylyltetrazole nonpeptide angiotensin II receptor antagonist are presented. The parent diacid analog, SK&F 108566 or (E)-3-
详细描述了非肽血管紧张素II受体拮抗剂的咪唑5-丙烯酸系列的进一步发展(关于第1部分,请参阅:J。Med。Chem。1992,35,3858)。为了模拟血管紧张素II的Tyr4残基,进行了N-苄基环取代的修饰。在N-苄基环上引入对羧酸导致发现了对受体具有纳摩尔摩尔亲和力和良好口服活性的化合物。这些有效拮抗剂的SAR研究表明,除了两个酸性基团以外,噻吩基环,(E)-丙烯酸和咪唑环对于高效力也很重要。另外,提出了母体二酸与血管紧张素II和代表性的联苯基四唑非肽血管紧张素II受体拮抗剂的叠加比较。母体二酸类似物SK&
