(-)-Hydroxycitric acid (HCA) can inhibit fat synthesis and reduces food intake, the primary mechanism of action of HCA appears to be related to its ability to act as a competitive inhibitor of the enzyme ATP-citrate lyase, which catalyzes the conversion of citrate and coenzyme A to oxaloacetate and acetyl coenzyme A (acetyl-CoA), primary building blocks of fatty acid and cholesterol synthesis.
Beta-Tocotrienol to serve as a new anticancer agent for treating human lung and brain cancers. It inhibits the growth of both A549 (GI50=1.38±0.334μM) and U87MG (GI50=2.53±0.604μM) cells at rather low concentrations.
