Preparation of 20-(hydroxymethyl)-4-methyl-4-aza-2-oxa-5.alpha.-pregnan-3-one as an inhibitor of testosterone 5.alpha.-reductase
摘要:
20-(Hydroxymethyl)-4-methyl-4-aza-2-oxa-5 alpha-pregnan-3-one and the corresponding 3-thione were synthesized with use of 20-(hydroxymethyl)-4-methyl-4-aza-5 alpha-pregnan-3-one as the starting material. The compounds were tested in vitro for inhibition of testosterone 5 alpha-reductase and found to be weak inhibitors with Ki's in the 10(-7) range.
Compounds of Formula (I), ##STR1## wherein X is sulfur or oxygen are inhibitors of the 5.alpha.-reductase enzyme and isozymes thereof. The compounds are useful for the treatment of hyperandrogenic disease conditions and diseases of the skin and scalp.
