research Activity of 17β-(N-Alkyl/arylformamido) and 17β-[(N-Alkyl/aryl) alkyl/arylamido]-4-methyl-4-aza-5α-androstan-3-ones as 5α-Reductase Inhibitors in the Hamster Flank Organ and Ear11The research has been supported by Endorecherche that is seeking patent protection for the new compounds. F. Labrie is President of Endorecherche.
This study observed that the compound EM-402 reduced 5α-reductase activity and sebaceous gland size in the flank organs and ears of hamsters, indicating potent localized anti-androgenic effects without systemic action.
