(±)-β-Tocopherol is a lipid-soluble form of vitamin E with antioxidant activity. It scavenges 2,2-diphenyl-1-picrylhydrazyl (DPPH; ) radicals with an EC 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.

β - Tococopherol (50 μ M, 48 hours) mildly inhibited the proliferation of A7r5 cells (inhibition rate of 10%) and CHO cells (inhibition rate of 20%), but had no inhibitory effect on HeLa cells [2]. β - Tococopherol (50 μ M, 24 hours) inhibited PMA (HY-18739) - induced cell adhesion in human erythroleukemia (HEL) cells (inhibition rate 11%), and suppressed the expression of integrins α 4 and α 5 on the cell surface [3].
