In the search for aldosterone antagonists with an optimal activity profile, twelve 9α, 11-epoxy-steroids were prepared and compared with their 9α, 11α -unsubstituted analogues in terms of steroid receptor binding in vitro and electrolyte excretion in vivo. Substitution of the parent structures by an epoxy group at positions 9α, 11 resulted in marginal effects on mineralocorticoid receptor binding and
在寻找具有最佳活性特征的醛固酮拮抗剂时,制备了十二种9α,11-环氧-类固醇,并与它们的9α,11α-未取代的类似物在体外类固醇受体结合和体内电解质排泄方面进行了比较。母体结构在位置9α,11处被环氧基取代,对盐皮质激素受体结合和电解质排泄产生了边际影响,但大大降低了雄激素和孕激素受体的结合。这一发现反映在三种最有趣的9α,11-环氧-螺内酯4(CGP 33033),18(CGP 29245)和25(CGP 30083)的动物模型中,在很大程度上缺乏不需要的抗雄激素和孕激素副作用。
