Orlistat is an inhibitor of fatty acid synthase that is clinically administered for its anti-obesity benefits. Orlistat is often used as a weight loss aid, although it also exhibits anticancer chemotherapeutic activity. In animal models of T cell lymphoma, orlistat increases levels of ROS, NO, caspase 3, Bcl-2, and p53, increasing life span and inhibiting tumor growth; similar results are found in animal models of colorectal carcinoma.
