ids as inhibitors of human type I 5 alpha-reductase (5 alpha-Re) were prepared from 17 beta-N-alkyl-4-methyl-4-aza-5 alpha-androstan-3-ones and various isocyanates. For the measurement of 5 alpha-Re activity, 293 cells transfected with human type I 5 alpha-Re, cDNA were used. Azasteroids with an N-cyclopropyl ring exhibited potent inhibitory activity against type I 5 alpha-Re. As the chain length increased
