γ-Tocotrienol is a form of vitamin E that has been found in rice bran and has diverse biological activities. It reduces cell death induced by hydrogen peroxide, paraquat, S-nitrocysteine, SIN-1 , or L-buthionine-(S,R)-sulfoximine (BSO; ) in rat striatal cultures when used at concentrations ranging from 0.1 to 10 μM. γ-Tocotrienol (20 μM) induces apoptosis in malignant sympathoadrenal (+SA) mouse mammary epithelial cells. In vivo, γ-tocotrienol (15, 30, and 150 mg/kg) reduces blood pressure and plasma lipid peroxide levels in spontaneously hypertensive rats. [Matreya, LLC. Catalog No. 2111]
γ-Tocotrienol exhibits antioxidant properties and belongs to the vitamin E family. It is naturally found in wheat germ oil and bran. In addition, α-tocopherol and γ-tocotrienol derivatives are potential lead compounds for developing?anticancer and?antiproliferative agents against?MCF-7 and MDA-MB-231 breast cancer cells and the A549 lung cancer cells.
