The invention relates to compounds of the formula :
wherein :
R1, R2, R3, R4 and R6 each independently represent hydrogen or a (C1-C6)alkyl,
R5 is hydrogen, a (C1-C6)alkyl or a group -COR7 where R7 is a (C1-C6)alkyl,
n is zero or one, and
X is oxygen or an hydroxyimino group,
provided that when n = 0, at least two of R1, R2, R3 and R4 are different from hydrogen and that when n = 1, R3 and R4 are not simultaneously hydrogen,
and to pharmaceutical compositions containing them.
These compounds are excellent progestogens and are devoid of residual androgenic activity.
本发明涉及式 :
其中:
R1、R2、R3、R4 和 R6 各自独立地代表氢或(C1-C6)烷基、
R5 是氢、(C1-C6)烷基或基团-COR7,其中 R7 是(C1-C6)烷基、
n 为 0 或 1,以及
X 是氧或羟基亚
氨基、
当 n = 0 时,R1、R2、R3 和 R4 中至少有两个不同于氢,当 n = 1 时,R3 和 R4 不能同时为氢、
以及含有它们的药物组合物。
这些化合物是优良的孕激素,没有残余雄激素活性。
