containing inhibitors of angiotensin converting enzyme have been designed and synthesized. The compounds are highly potent enzyme inhibitors and, as a consequence of conformational restriction, chemically stable with respect to undesirable cyclization reactions. The most interesting compound from this series, 5a (FPL 63547), is the monoethyl ester prodrug of the highly potent "aminocarboxy" inhibitor 5b (FPL
设计并合成了两个新系列的含二氢噻二唑环的血管紧张素转化酶抑制剂。该化合物是高效的酶抑制剂,并且由于构象限制,对于不希望的环化反应而言是化学稳定的。该系列中最有趣的化合物5a(FPL 63547)是高效的“氨基羧基”抑制剂5b(FPL 63674)的单乙酯前药。口服给药后,可在动物模型中长期产生降压作用。与其他ACE抑制剂不同,大鼠体内的胆汁清除几乎消除了5b。根据5a和5b的独特理化特性,合理化了其药理特性。用5b观察到的对胆道清除的明显偏爱与其亲脂性和在生理pH下的高净离子化程度相一致,这是由于C端羧酸功能的pKa值非常低所致。FPL 63547目前正在人体中进行临床研究。
