Exemestane Powder CAS 107868-30-4 is an irreversible steroid aromatase inhibitor. Its structure is similar to that of aromatase’s natural substrate, androstenedione, and acts as a pseudosubstrate. Postmenopausal women’s estrogen is mainly converted from androgen (produced by the adrenal cortex) by aromatase in the surrounding tissue.
Exemestane irreversibly binds with the active site on aromatase to deactivate it, thus dramatically lower estrogen levels in the blood circulation of postmenopausal women.
