Description:
Fadrozole HCl hydrate (CGS 16949A) is a highly potent and selective nonsteroidal
aromatase inhibitor (IC50 of 6.4 nM) with potential antineoplastic
activity. Aromatase, a member of the cytochrome P-450 superfamily, is
found in many tissues; overexpression has been linked to the development
of preneoplastic and neoplastic changes in breast tissue. Check for
active clinical trials or closed clinical trials using this agent.
Fadrozole specifically inhibits aromatase, blocking the aromatization of
androstenedione and testosterone into estrone and estradiol,
respectively, the final step in estrogen biosynthesis; the reduction in
estrogen levels may inhibit growth in estrogen-dependent cancers.
