some readily accessible, simpler 5asteroids, namely the 17-amino-5-a-androstan-3-ols (I-IV) which are epimeric at C(3) and C(7), and examined their antiarrhythmic activity~ The greatest activity was shown by the 38, 178epimer (I), which was used to obtain a series of N-alkyl and N-aminoacyl derivatives.
一些不具有激素特性的甾体胺具有抗心律失常、降血压或强心作用 [3, 6, 9]。Campbell 和 Williams [5] 推荐使用 3=-amino-5=-androstan-28-ol-17-one 治疗心律失常。我们现在已经从自制的植物材料中合成了一些容易获得的、更简单的 5asteroid,即 17-amino-5-a-androstan-3-ols (I-IV),它们在 C(3) 和 C(7) 处是差向异构的, 并检查了它们的抗心律失常活性~ 38, 178 差向异构体 (I) 显示出最大的活性,它被用来获得一系列 N-烷基和 N-
