Fadrozole free base

    WARNING: This product is for research use only, not for human or veterinary use.

MedKoo CAT#: 205962

CAS#: 102676-47-1 (free base)

Description: Fadrozole is a nonsteroidal aromatase inhibitor with potential antineoplastic activity. 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. 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. (NCI Thesaurus).
