administration. Alkylation of the morpholinyl substituent or chlorination at C-21 afforded the novel amino steroids (2 beta,3 alpha,5 alpha)-3-hydroxy-2-(2,2-dimethyl-4-morpholinyl)-pregnane-11,20-dione (19) and (2 beta,3 alpha,5 alpha)-21-chloro-3-hydroxy-2-(4-morpholinyl)pregnan-20-one (37) that were more potent and advantageously produced shorter sleep times than related compounds which were previously
合成了带有3个β-吗啉基取代基的(3 alpha,5 alpha)-3-羟基孕三烯酮20-ones和(3 alpha,5 alpha)-3-hydroxypregnane-11,20-diones,这些类固醇作为通过确定静脉内给药后小鼠中催眠药的效力和催眠活性的持续时间来评价麻醉药。吗啉基取代基的烷基化或C-21的氯化反应得到了新型的氨基类固醇(2 beta,3 alpha,5 alpha)-3-羟基-2-(2,2-二甲基-4-吗啉基)-孕烷11,20 -二酮(19)和(2 beta,3 alpha,5 alpha)-21-氯-3-羟基-2-(4-吗啉基)pregnan-20-一(37)更有效且有利地缩短了睡眠时间比以前报道的相关化合物要多。此外,这些和其他氨基类固醇的盐通常保持良好的水溶性。在放射性配体结合试验中,这些化合物抑制了[35S]-叔丁基双环磷酸硫酸酯与大鼠全脑膜的特异性结合,
