Pharmaceutical compositions and methods of their use are also provided for.
摘要:
New 17β-aminobenzoyl-4-aza-5α-androst-1-en-3-ones as benign prostatic hypertrophy agents of the formula:
wherein R is selected from hydrogen, methyl and ethyl and R² is phenyl substituted with -N(R₃)₂, which can be protected, where R₃ is independently H or C₁-C₄ alkyl, wherein the phenyl ring can also be further substituted by C₁-C₄ alkyl, wherein the dotted line can represent a double bond, and pharmaceutically acceptable salts thereof, and a pharmaceutical formulation thereof. The above compounds are active as benigh prostatic hypertrophy therapy agents and are useful topically for the treatment of acne, seborrhea, female hirsutism, and particularly effective systemically in the treatment of benign prostatic hypertrophy.
摘要:
Specific 17β-thiobenzoyl-4-aza-5α-androst-1-en-3-ones as antiandrogenic agents of the formula:
wherein
R is selected from hydrogen, methyl and ethyl and R ² is phenyl substituted with one or more of: -SH, -SC₁-C₄ alkyl, -SO-C₁-C₄alkyl, -SO₂-C₁-C₄ alkyl, -SO₂N-(C₁-C₄ alkyl)₂, C₁-C₄ alkyl, -(CH₂) m SH, -S(CH₂) n OCOCH₃, where m is 1-4, n is 1-3, and providing C₁-C₄ alkyl is only present when one of the above sulfur- containing radicals is present, wherein the dotted line can represent a double bond, and pharmaceutically acceptable esters and salts thereof. Also included is a pharmaceutical formulation thereof. The above compounds are active as antiandrogenic agents and thus are useful topically for treatment of acne, seborrhea, female hirsutism, and systemically in treatment of benign prostatic hypertrophy.
