Anastrozole

Anastrozole (aromatase inhibitor) has been used:

• as a positive control in DNA fragmentation (ladder) assay
• to investigate its effects along with extra virgin olive oil and its major fatty acid component (omega-9 OA) in estrogen receptor positive mammary adenocarcinoma cells
• to study its effects on viability, cell proliferation and apoptosis in Glioblastoma multiforme model in vivo

Anastrozole is a nonsteroidal aromatase inhibitor.

Anastrozole, which contains a triazole functional group, reversibly binds to the cytochrome P-450 component of aromatase. Binding interferes with the catalytic properties of aromatase, which results in inhibition of estrogen synthesis.

The aromatase enzyme converts adrenal androgens to estrogen; this enzymatic activity is the primary source of estrogen production in postmenopausal women. One treatment for estrogen receptor-positive breast cancer in postmenopausal women is through inhibition of aromatase. Anastrozole is a nonsteroidal, benzyl-triazole derivative that inhibits aromatase through competitive inhibition and is used to treat estrogen receptor-positive breast cancer. This compound is considered a third-generation, Type II aromatase inhibitor because it is more selective and less effective (if at all) on other steroidal hormones than first and second generation inhibitors.
