生育酚衍生物
生育酚主要有四种衍生物,按甲基位置分为α、β、γ和δ四种。与生育酚相关的化合物生育三烯酚在取代基不同时活性是一定的,但生育酚的活性会明显降低。
下为二者结构简式:
下表列出用以下官能团取代后生育三烯酚与生育酚的活性比:
生物活性
γ-Tocopherol (D-γ-Tocopherol) 是有效的环氧合酶 (cyclooxygenase) 抑制剂。γ-Tocopherol 是维生素 E 的天然形式,存在于许多植物种子中,例如玉米油和大豆。γ-Tocopherol 具有抗炎特性和抗癌活性。靶点
Cyclooxygenase

体外研究
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.
