  摘要：

  合成了几种具有δ11-孕烷骨架，具有17-γ-螺内酯功能的类固醇衍生物，以评估其抗醛固酮活性并阐明其与盐皮质激素受体（MR）的结合亲和力与盐皮质激素和/或抗盐皮质激素活性之间的关系。虽然许多合成的化合物显示出对MR和醛固酮激动剂活性的强结合亲和力，但3-（17β-羟基-3-氧代雄甾烯1,4,6,11-四烯-17α-基）丙酸γ-内酯在体内试验中显示出良好的醛固酮拮抗剂活性。还发现其体内抗雄激素活性相对较弱。

• Structure-activity relationship study of spirolactones. Contribution of the cyclopropane ring to antimineralocorticoid activity

  日期：1981.9

  A series of spirolactones containing a cyclopropane ring in the molecule was examined for its effects on the mineralocorticoid receptor. The results were compared with those of a similar series of spirolactones in which the cyclopropane ring was replaced by a double bond. Insertion of a double bond or an alpha-cyclopropane ring into the 1,2 or the 6,7 position leads to a reduction in the binding affinity. The pi-bonding system of the beta-cyclopropane ring at C-6 and C-7 does not promote binding to the receptor. The presence of the 6 beta, 7 beta-cyclopropane ring may deter metabolic activation to account for the enhanced in vivo activity.
