(dichloromethane extract) and certain derivatives of Lithrea caustica (Molina) Hook and Arn. (Anacardiaceae) as inhibitors of 15 soybean and 5 human lipoxygenases (15-sLOX and 5-hLOX). From the epicuticular extract of leaves, the compound (Z)-3-(pentadec-10'-enyl)-catechol (Litreol) was isolated, and three hemisynthetic derivatives were prepared, as they are 3-pentadecylcatechol, (Z)-1,2-diacetyl-3-(pentadec-10'-enyl)-benzene
我们的调查侧重于表皮叶提取物(二氯甲烷提取物)和 Lithrea caustica (Molina) Hook 和 Arn 的某些衍生物的表征和研究。(漆树科)作为 15 种大豆和 5 种人脂肪氧化酶(15-sLOX 和 5-hLOX)的抑制剂。从叶表皮提取物中分离出化合物(Z)-3-(pentadec-10'-enyl)-catechol (Litreol),制备了三种半合成衍生物,即3-pentadecylcatechol, (Z)-1 ,2-二乙酰-3-(十五-10'-烯基)-苯和1,2-二乙酰-3-十五烷基苯。测定了四种化合物对 15-sLOX 和 5-hLOX 的抑制活性,分别是 (Z)-3-(pentadec-10'-enyl)-catechol(IC50 分别为 54.77 μM 和 2.09 μM)和 3-pentadecylcatechol( IC50 分别为 55.28
