D-alpha-Tocopherol acetate (Vitamin E Acetate) is hydrolyzed to d-alpha-tocopherol (VE) and absorbed in the small intestine.

DL-α-tocopherol methoxypolyethylene glycol succinate solution (TPGS-750-M) is a hydrophilic lipid molecule that acts as a surfactant.

Jacaric acid is a conjugated polyunsaturated fatty acid first isolated from seeds of Jacaranda plants. Structurally, it is an 18-carbon ω-6 triene isomer of γ-linolenic acid . Jacaric acid induces cell cycle arrest and apoptosis in a variety of cancer cell lines (GI50 = 1-5 μM). It increases the production of reactive oxygen species, and cytotoxicity is abolished by the antioxidant α-tocopherol, suggesting that apoptosis results from oxidative stress. Jacaric acid is metabolized in vivo to conjugated linoleic acid , which is also cytotoxic to cancer cells. Jacaric acid inhibits cyclooxygenase-1 in vitro (Ki = 1.7 μM) and, with long term feeding, decreases stearoyl-CoA desaturase expression and activity in mice.

2-Oxopomolic acid shows cytotoxic activity, it shows a significant decrease in intracellular melanin content in B16-F10 cells, and in culture media melanin. 2-Oxopomolic acid shows radical-scavenging activities similar to that of the reference antioxidant

(±)10-HDHA is an autoxidation product of docosahexaenoic acid (DHA) in vitro.[1][2] It is also produced from incubations of DHA in rat liver, brain, and intestinal microsomes.[3][4][5] (±)10-HDHA is a potential marker of oxidative stress in brain and retina where DHA is an abundant polyunsaturated fatty acid.

(±)-5,7-Dimethyltocol is a form of tocopherol. It has similar antioxidant activity to α-tocol, but lower activity than γ-tocol, in antioxidant assays using menhaden oil or squalene as substrates. It also increases microviscosity of rat liver liposomes containing phosphatidylcholine (PC) by 70.6% when used at a molar ratio of 0.2 to PC. (±)-Dimethyltocol has been used as an internal standard for the quantification of 5,7-tocol, α- and γ-tocopherol, and α- and γ-tocopheryl quinone by HPLC.

Vitedoin A shows stronger antioxidative activity than alpha-tocopherol using the ferric thiocyanate method, it also shows higher radical-scavenging effect on the stable free radical, 1,1-diphenyl-2-picrylhydrazyl, than L-cysteine.

Vitamin E succinate (D-alpha-Tocopherol Succinate) is an antioxidant tocopherol that belongs to the vitamin E class of compounds Vitamin E succinate has antitumor activity, induces apoptosis, and is used as an adjuvant in the treatment of cancer and in the synthesis of INVITE, a biocoupling compound.

Tocofersolan (TPGS) is a polyethylene glycol derivative of α-tocopherol and synthetic water-soluble version of Tocopherol. Tocofersolan is an oral treatment of vitamin E deficiency due to digestive malabsorption in pediatric patients with congenital chronic cholestasis or hereditary chronic cholestasis.

DL-alpha-Tocopherol (Ephanyl) is a synthetic vitamin E that protects skin fibroblasts from the cytotoxic effects of UV light and has antioxidant properties.

Tubuloside A ( 8.6 microM) can inhibit D-galactosamine-induced death of hepatocytes. Tubuloside A has NO radical-scavenging activity, which possibly contributes to its anti-inflammatory effects.Tubuloside A shows stronger free radical scavenging activitie

(±)-α-Tocopherol nicotinate is a useful organic compound for research related to life sciences. The catalog number is T64563 and the CAS number is 51898-34-1.

γ-CEHC, a metabolite of γ-tocopherol, is predominantly excreted through urine, primarily in its conjugated form as glucuronide [1], rather than through bile.

α-Tocopherol phosphate (alpha-Tocopherol phosphate) is an antioxidant that scavenges UVA1-induced reactive oxygen species (ROS) and protects against long-wave UVA1-induced cell death. alpha-Tocopherol phosphate disodium impedes endothelial progenitor cell apoptosis, enhances endothelial progenitor cell migration under high glucose/low oxygen conditions and promotes angiogenesis. α-Tocopherol phosphate disodium (Vitamin E phosphate disodium) prevents apoptosis, enhances migration of endothelial progenitor cells under high glucose/low oxygen conditions and promotes angiogenesis.

(±)-γ-Tocopherol is a form of vitamin E with antioxidant and anti-inflammatory properties. It traps and detoxifies reactive nitrogen oxide species, including nitrogen dioxide, in cell-free assays. It also reduces the synthesis of prostaglandin E2 (PGE2) induced by LPS in RAW 264.7 macrophages and by IL-1β in A549 cells. (±)-γ-Tocopherol inhibits LPS-induced nitrite release and inducible nitric oxide synthase (iNOS) expression in RAW 264.7 cells and reduces COX-2 activity in A549 cells pretreated with IL-1β. Serum levels of (±)-γ-tocopherol are decreased in patients with cardiovascular disease.

α-Tocopherol phosphate is the compound demonstrating the highest vitamin E activity.
