Novel 17β-hydroxybenzoyl-4-aza-5α-androst-1-en-3-ones as testosterone reductase inhibitors of the formula:
wherein
R isselected from hydrogen, methyl and ethyl and
R² isphenyl substituted with one or more of: -OH, -OC₁-C₄ alkyl, C₁-C₄ alkyl, -(CH₂)mH, -(CH₂)n COOR, including protected -OH, where m is 1-4, n is 1-3, and providing C₁-C₄ alkyl is only present when one of the above oxygen containing radicals is present, wherein the dotted line represents a double bond which can be present, pharmaceutically acceptable salts and esters thereof, and a pharmaceutical formulation thereof. The above compounds are active as testosterone reductase inhibitors and thus are useful topically for treatment of acne, seborrhea, female hirsutism, and systemically in treatment of benign prostatic hypertrophy.
