The simple, concise, protecting group free and first total synthesis of Metatacarboline alkaloids (abbreviated as Mc) Mc A, C, D, E and F are reported. The core structure of metatacarboline alkaloids has been constructed by the classical Wittig reaction as key step from easily accessible starting materials with 40–75% overall yields. These synthesized compounds have been subjected to evaluate for their
报道了Metatacarboline生物碱(简称为Mc)的简单,简洁,无保护基团的首次全部合成。Mc A,C,D,E和F。通过经典的维蒂希反应(Wittig reaction)已构建了metacarboline生物碱的核心结构,这是从容易获得的起始原料中获得的关键步骤,该原料的总收率为40-75%。使用C6神经胶质瘤细胞系对这些合成的化合物进行了抗癌活性评估。Mc D和Mc F显示出显着的抗增殖活性,这已通过MTT和Clonogenic分析得以证实。FACS分析表明,Mc D和Mc F分别将细胞周期停滞在亚细胞周期的G0 / G1和G2 / M期。此外,蛋白质印迹分析和Mc D处理的细胞的免疫组织化学显示,caspase依赖性下游信号传导被激活,从而导致细胞凋亡。
