cfg 920.

EC18 is a bioactive chemical.

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.
