IZONSTERIDE, a benzoquinolinone, is a selective inhibitor of the 5-alpha reductase, with antagonistic effect on both the type I (liver, skin, hair follicles) and type II (prostate) isoforms of the enzyme. It is a competitive inhibitor of type I 5-alpha reductase and a non-competitive inhibitor of type II 5-alpha reductase. It was under development for the treatment of prostatic cancer.
