The invention relates to a novel multi step process of making compounds of Formula I:
wherein R
1
is an alkoxy group and R
2
is an optionally substituted, N-attached heteroaryl. The hydrogen at the 5-position can be α or β isomer, preferably α. Preferably the compound of Formula I is 17β isomer. The invention also relates to novel 3α-hydroxy-3β-substituted-17-substituted steroid compounds having GABA
A
receptor modulating activity, pharmaceutical compositions comprising these compounds, and the use of these compounds in a method of modulating brain excitability.
本发明涉及一种制备公式I化合物的新型多步骤过程:其中R1是烷氧基,R2是可选择性取代的、N-连接的杂环芳基。5位氢可以是α或β异构体,优选为α。优选的公式I化合物是17β异构体。本发明还涉及具有
GABAA受体调节活性的新型3α-羟基-3β-取代-17-取代类
固醇化合物、包含这些化合物的制药组合物以及使用这些化合物调节脑兴奋性的方法。
