The first Z-stereoselective method for the synthesis of the natural marine alkynol lembehyne C, containing a 1Z,5Z,9Z-triene moiety, in 41% yield was developed using the new Ti-catalyzed cross-coupling of oxygenated and aliphatic 1,2-dienes as the key step. It was found for the first time that lembehyne C exhibits moderate cytotoxicity against Jurkat, K562, U937, and HL60 cancer cells and also efficiently
第一种合成天然海洋炔醇 lembehyne C 的Z立体选择性方法,含有 1 Z ,5 Z ,9 Z三烯部分,产率 41% 1,2-二烯作为关键步骤。首次发现 lembehyne C 对 Jurkat、K562、U937 和 HL60 癌细胞表现出中等细胞毒性,并有效诱导 Jurkat 细胞凋亡,细胞死亡机制被线粒体途径激活。细胞周期的 lembehyne C 抑制遵循有丝分裂灾难机制。
