Description and Uses
(±)-β-Tocopherol is a lipid-soluble form of vitamin E with antioxidant activity. It scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; ) radicals with an EC50 value of 68.2 μM. (±)-β-Tocopherol (100 μM) inhibits LPS-induced COX-2 gene expression in mouse RAW 264.7 macrophage cells. Unlike (±)-α-tocopherol , (±)-β-tocopherol does not inhibit smooth muscle cell proliferation, decrease PKC activity, increase phosphoprotein phosphatase 2A (PP2A) activity, or modify expression of the α-tropomyosin gene. [Matreya, LLC. Catalog No. 1071]
One of the naturally occurring forms of Vitamin E. Is biologically less active than α-Tocopherol. This is the racemic mixture of all stereoisomers.
