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.
该发明涉及替代的2.beta.-
吗啡啶基-雄烷衍
生物,它们以其2.beta.-位置与式I的一个羰基的氮键合在一起,其中R代表一个到四个取代基,每个独立选择自(1-4C)烷基、苯基和苄基,或者两个在同一碳原子上结合成--(CH.sub.2).sub.n--,其中n为2-6;Y为O或S,或其药用盐。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起效时间和理想的“睡眠持续时间”与“恢复到完全协调”的特性。
