17β-N-monosubstituted carbamoyl or 17β-acyl-4-aza-5α--androst-1 -en-3-ones of the formula:
in which R is hydrogen, methyl or ethyl;
R2 is a C1-12 straight or branched alkyl radical or a monocyclic aryl optionally containing one or more methyl or ethyl substituents and/or one or more Cl, F or Br substituents; and in Formula IA R2 may also be benzyl, phenethyl, 2-pyridyl, 4-pyridyl, 2-pyrrolyl, 2-furyl or thiophenyl;
R' is hydrogen or methyl;
R" is hydrogen or β-methyl and in Formula IA may also be a-methyl; and
R"' is hydrogen, a-methyl or β-methyl and pharmaceutical formulations containing the above compounds are active as testosterone 5a-reductase inhibitors and thus are useful topically for treatment of acne, seborrhoea and female hirsutism, and systemically in the treatment of benign prostatic hypertrophy.
式中的 17β-N-单取代氨基甲酰基或 17β-酰基-4-氮杂-5α-雄甾烷-1-烯-3-酮:
其中 R 为氢、甲基或乙基;
R2 是 C1-12 直链或支链烷基或单环芳基,任选含有一个或多个甲基或乙基取代基和/或一个或多个 Cl、F 或 Br 取代基;在式 IA 中,R2 也可以是苄基、苯乙基、2-吡啶基、4-吡啶基、2-吡咯基、2-呋喃基或噻吩基;
R' 是氢或甲基;
R" 是氢或β-甲基,在式 IA 中也可以是 a-甲基;以及
