生育酚衍生物
生育酚主要有四種衍生物，按甲基位置分為α、β、γ和δ四種。與生育酚相關(guān)的化合物生育三烯酚在取代基不同時(shí)活性是一定的，但生育酚的活性會(huì)明顯降低。
下為二者結(jié)構(gòu)簡(jiǎn)式：
下表列出用以下官能團(tuán)取代后生育三烯酚與生育酚的活性比：
生物活性
γ-Tocopherol (D-γ-Tocopherol) 是有效的環(huán)氧合酶 (cyclooxygenase) 抑制劑。γ-Tocopherol 是維生素 E 的天然形式，存在于許多植物種子中，例如玉米油和大豆。γ-Tocopherol 具有抗炎特性和抗癌活性。靶點(diǎn)

體外研究
γ-Tocopherol (D-γ-Tocopherol) is well absorbed and accumulates to a significant degree in some human tissues; it is metabolized, however, largely to 2,7,8-trimethyl-2-(beta-carboxyethyl)-6-hydroxychroman (gamma-CEHC), which is mainly excreted in the urine.
Plasma concentrations of γ-Tocopherol (D-γ-Tocopherol) are inversely associated with the incidence of cardiovascular disease and prostate cancer.
