Total synthesis of viscolin, an anti-inflammatory 1,3-diphenylpropane isolated from Viscum coloratum, employing the Wittig reaction is reported. Key steps in the synthesis of viscolin depend on the selection of protecting groups to maintain the para hydroxyl group that is the most critical chemical structure influencing the biological activity of viscolin and the utilization of microwave-assisted Wittig
报道了使用Wittig反应的粘胶的全合成,粘胶是一种从发色豌豆(Viscum coloratum)分离的消炎的1,3-二苯基丙烷。粘胶蛋白合成的关键步骤取决于保护对羟基的保护基团的选择,该对羟基是影响粘胶蛋白生物学活性的最关键化学结构,并利用微波辅助的维蒂希(Wittig)烯化反应。评估了合成粘胶蛋白,其前体产物16及其类似物17的抗炎作用,这些作用是通过它们对白细胞和小胶质细胞中活性氧(ROS),一氧化氮(NO)以及促炎性细胞因子产生的影响来进行的。
