Description | Exemestane was launched in US and other countries for the treatment of estrogendependent tumors and postmenopausal breast cancer. It is a novel steroidal compound structurally related to the natural substrate for the biosynthesis of estrogen, androstanedione, and can be synthesized by methylidenation of androsta-1, 4-dien- 17beta-ol-3-one in 6 position then oxidation of the alcohol function. Exemestane is an irreversible inactivator of the aromatase enzyme system, so inducing in vivo a dose-related sustained suppression of serum estrogen and minimal endocrine activity. It is the first steroidal representative of the third-generation of orally active aromatase inhibitors with a highly potent and selective mechanism of action, displaying good tolerability and safety profile. In rats with DMBA-induced mammary tumors, 10 to 100 mglkg of exemestan administered po twice-daily for 4 weeks resulted in 76 to 88% regression. In women failing anti-estrogen therapy with tamoxifen, this agent has demonstrated high activity in locally advanced or metastatic disease. In addition, it may also have potential for breast cancer prevention. |
Chemical Properties | white to light yellow crystal powder |
Originator | Farmitalia Carlo Erba (Italy) |
Uses | An antineoplastic (hormonal) |
Uses | antiinfective |
Uses | Labeled Exemestane, intended for use as an internal standard for the quantification of Exemestane by GC- or LC-mass spectrometry. |
