(±)-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.

Dehydro-δ-tocopherol shows antioxidant capacities.

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

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

alpha-Tocopherolquinone (Metarene) 会下调线粒体的呼吸活动。在还原为生育酚氢醌后，它还显示出抗氧化活性。在大鼠缺氧期间，已发现它的水平升高。

2,2,5,7,8-Pentamethyl-6-Chromanol (PMC) 是维生素 E (α-tocopherol) 的抗氧化部分，能够有效的调节雄激素受体 (androgen receptor) 信号，及抗前列腺癌细胞系的抗癌活性。

Tocofibrate是一种包含氯贝酸和α-生育酚的过氧化物诱导性酯类化合物。

(±)-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.

(±)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.
