A series of 4-aza-5α-androstane compounds with one or two aromatic moieties in the carbamoyl group at the C-17 position were synthesized and their inhibitory activities for rat and human prostatic testosterone 5α-reductase were tested in vitro. Compounds with one aromatic moiety in the carbamoyl group showed high inhibitory activity for rat 5α-reductase, but little for human prostatic 5α-reductase. On the other hand, compounds with two aromatic moieties had potent inhibitory activities for both rat and human 5α-reductase. The structural requirements for potent inhibition for both enzymes are discussed in relation to the spatial arrangement of the C-17 carbamoyl group.
