Alpha-tocopherol ((+)-alpha-tocopherol) functions as a scavenger of peroxyl radicals. This action is crucial because it keeps long-chain polyunsaturated fatty acids in cell membranes intact, which preserves the biological activity of the fatty acids [1]. It has been reported that alpha-vitamin E ((+)-alpha-tocopherol) inhibits PKC in a variety of cell types, which in turn inhibits the formation of superoxide, nitric oxide by endothelial cells, and platelet aggregation in neutrophils and macrophages. The activation of the MAP kinase and PI3 kinase (PI3K) pathways was enhanced by exposure to α-tocopherol ((+)-α-tocopherol), suggesting that oxidative stress upregulates both the kinase pathway and the antioxidant effect of α-. Fatty acids in cell membranes are shielded by tocopherol [1]. It has been shown that alpha-vitamin E, also known as (+)-alpha-tocopherol, is protective against influenza A virus infection and may also be effective against hepatitis B and C. Proviral effects of α-tocopherol are observed, particularly in HEK293T/17 cells [3].

Alpha-vitamin E ((+)-alpha-tocopherol) inhibits development of proinflammatory cytokines IL-1, IL-6, and IFN-γ mRNA and protein compared with ischemia-reperfused myocardium of untreated pigs Increase undamaged area[1]. Treatment with alpha-vitamin E (D-alpha-tocopherol; intraperitoneally or orally) improves diabetic nephropathy in mice by activating diacylglycerol kinase alpha (DGKα) and reducing podocyte loss [2].

Solubility in Formulation 1: ≥ 11.25 mg/mL (26.12 mM) (saturation unknown) in 10% EtOH + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 112.5 mg/mL clear EtOH stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: 11.25 mg/mL (26.12 mM) (saturation unknown) in 10% EtOH + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), suspension solution; with ultrasonication. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 112.5 mg/mL clear EtOH stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly.

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
