Anastrozole Chemical Properties,Usage,Production

letrozole and anastrozole
Anastrozole is an inhibitor for the triazole aromatase with a strong selectivity. It can inhibits aromatase which is prerequisite for the synthesis of pigment cells P-450 thereby blocking the biosynthesis of estrogens, and the estrogen is the essential part of the growth of breast cancer cells. The 50% inhibitory concentration (IC50) value of anastrozole to placental aromatase is 15nmol/L.
Letrozole is used for the treatment of advanced breast cancer of postmenopausal women.It mainly applied to the second-line treatment after the failure of the anti-estrogen treatment.
Chemical properties
It can be crystallized from ethyl acetate – cyclohexane, the melting point is 81~82℃.
Anastrozole would become the standard of adjuvant therapy for breast cancer
One the world's largest and longest research of clinical trials about using the aromatase inhibitors in adjuvant therapy for breast cancer shows the latest results that: Compared with conventional drugs like tamoxifen, anastrozole can reduce the risk of the recurrence and metastasis of breast cancer effectively and comprehensively,prolong disease-free survival; even the patient has completed the treatment for 4 years, the protective effect of anastrozole remains sustainable. Professor Xu B,H, who is the deputy director of Medical Oncology of Chinese Academy of Medical Sciences Cancer Hospital, recently proposed that, this indicate the anastrozole will become the standard scheme of adjuvant endocrine therapy for breast cancer.
According to Xu B,H, the commonly used traditional endocrine drugs after breast cancer surgery is tamoxifen. Tamoxifen has many side effects, such as the endometrial cancer and thromboembolic etc. This clinical trial compared the effect of the tamoxifen with third-generation aromatase inhibitors- anastrozole. There are 21 countries and 381 test centers participate in this  global multi-center clinical trial. They test 9366 patients for 100 months since 1996. The result shows that 25.8% of patients at anastrozole group recurred, and the recurrence rate for the patients at tamoxifen group was 29.9%, so anastrozole reduces the recurrence rate of 4.1% compare with the tamoxifen and also decrease the risk of distant metastasis at the same time. For security ,anastrozole is also superior to tamoxifen.
Uses
(1) It is the third-generation’s aromatase inhibitors, used for the treatment of advanced breast cancer of postmenopausal patients.
(2) Its used to cure the breast cancer.
(3) Anastrozole is the third-generation’s aromatase inhibitors, used for the treatment of advanced breast cancer of postmenopausal patients. It is an inhibitor for the triazole aromatase with a strong selectivity. It can inhibits aromatase which is prerequisite for the synthesis of pigment cells P-450 thereby blocking the biosynthesis of estrogens, and the estrogen is the essential part of the growth of breast cancer cells. Its used to cure the breast cancer, particularly suitable for postmenopausal women with advanced breast cancer who recrudescent after hormone adjuvant therapy.
Production methods
