Sell anti-estrogen steroid Exemestane Aromasin CAS 107868-30-4

Description

Exemestane is an aromatase inhibitor. This means it blocks the enzyme aromatase (found in the body's muscle, skin, breast and fat), which is used to convert androgens (hormones produced by the adrenal glands) into estrogen. In the absence of estrogen, tumors dependent on this hormone for growth will shrink.

Exemestanes Aromasin is an irreversible, steroidal aromatase inactivator, structurally related to the natural substrate androstenedione. It acts as a false substrate for the aromatase enzyme, and is processed to an intermediate that binds irreversibly to the active site of the enzyme causing its inactivation, an effect also known as "suicide inhibition." By being structurally similar to enzyme targets, Exemestanes Aromasin permanently binds to the enzymes, preventing them from converting androgen into estrogen.
