Basic Info
Model No.: X-CAS 112809-51-5
Product Description
Antineoplastic 112809-51-5 API Letrozole powder
Letrozole is a new generation of highly selective aromatase inhibitors, for the synthesis of benzotriazole derivatives, by inhibiting aromatase, so that estrogen levels, thereby eliminating the estrogen stimulation of tumor growth. In vivo activity than the first generation of aromatase inhibitors Ammonium strong 150-250 times. Because of its high selectivity, does not affect the glucocorticoid, mineralocorticoid and thyroid function, high-dose use of adrenal corticosteroid secretion without inhibition, and therefore have a high therapeutic index.
Preclinical studies have shown that letrozole is not potentially toxic, mutagenic and carcinogenic to systemic and target organs, with less toxic side effects and good tolerability, with Other aromatase inhibitors and Compared with estrogen drugs, anti-tumor effect is stronger. Suitable for the treatment of Anti-Estrogen therapy ineffective late breast cancer postmenopausal patients and early treatment of breast cancer.
Usage of Letrozole :
Antineoplastic cas 112809-51-5 used in the treatment of breast cancer, letrozole is a new generation of aromatase inhibitors, for the artificial synthesis of benzyl three azole derivatives, letrozole by inhibition of aromatase, which decreases the level of estrogen, thereby eliminating the stimulating effect of estrogen on the growth of tumor.
