Exemestane
Exemestane is a third generation aromatase inhibitor that prevents estrogen synthesis and is clinically used to treat ER+ breast cancer. Exemestane exhibits anticancer chemotherapeutic activity, inhibiting proliferation and inducing cell cycle arrest, apoptosis, and autophagy in breast cancer cells.
