Abstract
We present the SAR study that led us to identification of the first inhibitors of type 7 17β- hydroxysteroid dehydrogenase (17β-HSD). The conversion of E1 into E2 is reduced by nearly 90 % by 17β-(Nalkylformamido)- 4-methyl-4-aza-5α-androstan-3-one compounds bearing a side chain containing 7 to 10 carbon atoms when tested at 0.3 μM.
