Description
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.

Application
1)
By inhibiting aromatase to lower estrogen levels, it can be used to
treat hormone-dependent breast cancer in postmenopausal women.
2) Exemestane is suitable for treating advanced breast cancer in naturally or artificially postmenopausal women that has not responded well to tamoxifen treatment. It is also suitable for treating estrogen and progesterone receptor positive postmenopausal advanced breast cancer, and it can also be used to treat metastasized breast cancer and as adjuvant therapy for early breast cancer.
