Vitamin E Acetate

**Semantic type:** Pharmacologic Substance|Vitamin

**Definition:** The acetate ester of a fat-soluble vitamin with potent antioxidant properties. Considered essential for the stabilization of biological membranes (especially those with high amounts of polyunsaturated fatty acid), vitamin E is a generic name for a group of compounds known as tocopherols and tocotrienols (tocols). This agent is a potent peroxyl radical scavenger and inhibits noncompetitively cyclooxygenase activity in many tissues, resulting in a decrease in prostaglandin production. Vitamin E also inhibits angiogenesis and tumor dormancy through suppressing vascular endothelial growth factor (VEGF) gene transcription. (NCI04)
