Anastrozole, identified by CAS 120511-73-1, is a powerful tool in modern medicine, primarily recognized for its significant role in hormone therapy, particularly for managing estrogen-sensitive conditions like breast cancer. As a leading supplier of high-quality pharmaceutical intermediates, we provide Anastrozole that is central to these critical therapeutic applications.

The core function of Anastrozole is its action as a third-generation non-steroidal aromatase inhibitor. The aromatase enzyme is responsible for the final step in estrogen biosynthesis, converting androgens (like testosterone and androstenedione) into estrogens (estrone and estradiol). In postmenopausal women, the primary source of estrogen is the peripheral conversion of androgens, catalyzed by aromatase. By inhibiting this enzyme, Anastrozole effectively reduces the production of estrogen, which is crucial for cancers that are hormone receptor-positive (HR+).

Many breast cancers are fueled by estrogen. These HR+ breast cancers exhibit estrogen receptors on their cells, and estrogen binding stimulates their growth. By lowering estrogen levels, Anastrozole deprives these cancer cells of the growth signal, thereby slowing tumor growth or causing it to regress. This makes Anastrozole a vital component in the adjuvant treatment of early breast cancer to reduce the risk of recurrence and in the treatment of advanced or metastatic breast cancer.

The development and availability of Anastrozole have revolutionized treatment protocols for many patients. Its effectiveness, combined with a generally manageable side effect profile, has made it a preferred choice for many oncologists. For pharmaceutical manufacturers and researchers looking to buy Anastrozole, understanding its biochemical action is key to appreciating its therapeutic value.
