Abiraterone metabolite 1 is a 5β-reduced metabolite of abiraterone. Abiraterone inhibits CYP17A1, blocks androgen synthesis, and prolongs survival in prostate cancer.
BMS-351 is a potent and selective, nonsteroidal CYP17A1 lyase inhibitor with robust selectivity over steroidogenic CYPs 21A2 and 11B1. BMS-351 emerges as an outstanding preclinical candidate to treat CRPC and is likely to minimize the side effects of current therapies due to its exceptional selectivity. BMS-351 is potentially useful for the Treatment of Prostate Cancer.
CFG920 is a CYP17 inhibitor, is also an orally available inhibitor of the steroid 17-alpha-hydroxylase C17,20 lyase (CYP17A1 or CYP17), with potential antiandrogen and antineoplastic activities. Upon oral administration, CYP17 inhibitor CFG920 inhibits the enzymatic activity of CYP17A1 in both the testes and adrenal glands, thereby inhibiting androgen production. This may decrease androgen-dependent growth signaling and may inhibit cell proliferation of androgen-dependent tumor cells.
