Azasteroid

An azasteroid is a type of steroid derivative which has one of the carbon atoms in the steroid ring system replaced by a nitrogen atom.

Two azasteroids, finasteride and dutasteride, are used clinically as 5α-reductase inhibitors.

[1][2][3] Some of the 6-azasteroids may prove to be useful drugs, but have yet to reach the pharmaceutical market.
