The compounds of formula (I)
wherein R is selected from hydrogen, methyl or ethyl, and R¹ is C1-12 straight or branched chain alkyl wherein one of the hydrogens is substituted by hydroxy, carboxylic acid or C1-4 alkyl ester, and A is -CH₂-CH₂ or -CH=CH-, and pharmaceutical formulations of the above compounds are active as testosterone 5α-reductase inhibitors and thus are useful for treatment of acne, seborrhea, female hirsutism or benign prostatic hypertrophy.

In addition, 4-azasteroids with a D-homo ring or methyl substitution at C-7 (alpha and beta) or C-16 (alpha and beta) were prepared. The majority of the C-17 substituents were prepared from reactive intermediates derived from the 17 beta-COOH. Enhanced 5 alpha-reductase inhibition in both the human and rat enzyme assays is seen with 4-CN substitution on 3-oxo-delta 4 steroids and with a C-17 side
