All possible diastereoisomers of the dicarboxylic acid (10a), the biologically active form of imidapril (1), were synthesized, and their inhibitory activity against angiotensin converting enzyme (ACE) was examined. The in vitro ACE inhibitory activity of these compounds greatly depended on the configurations of the three asymmetric carbons in each molecule. The (S,S,S) isomer (10a) showed much more
合成了所有可能的二羧酸(10a)的非对映异构体(吡虫啉的生物活性形式),并检查了它们对血管紧张素转化酶(ACE)的抑制活性。这些化合物的体外ACE抑制活性很大程度上取决于每个分子中三个不对称碳的构型。(S,S,S)异构体(10a)的活性比其他异构体强得多。
