The invention is related to substituted 2.beta.-morpholino-androstane derivatives, bonded at their 2.beta.-position to the nitrogen of a group of formula I ##STR1## wherein R represents one to four substituents, each one independently selected from (1-4C) alkyl, phenyl and benzyl, or two at the same carbon atom being together --(CH.sub.2).sub.n -- wherein n is 2-6; and Y is O or S, or a pharmaceutically acceptable salt thereof. These steroids are very potent intravenous anaesthetics. The compounds have fast onset times and ideal `sleep duration` vs. `recovery to full coordination` profiles.
本发明涉及取代的2β-
吗啡啶基-雄烷衍
生物,它们与式I的基团上的氮原子结合在它们的2β-位置上。其中R代表1-4个取代基,每个基独立地选择自(1-4C)烷基,苯基和苄基,或者两个基在同一碳原子上结合成-(
CH2)n-,其中n为2-6; Y为O或S,或其药学上可接受的盐。这些类
固醇是非常有效的静脉
麻醉剂。这些化合物具有快速的起效时间和理想的“睡眠持续时间”与“恢复到完全协调”的特征。
