An efficient asymmetric synthesis of a cyclic depsipeptide arenastatis A (1) is described. 1, isolated from the marine sponge Dysidea arenaria, exhibited extremely potent cytotoxicity with IC50 of pg/ml for KB cells, and in this context the structure-activity relationship among several stereoisomers of 1 and allied compounds has also been examined.
本文描述了环缩肽沙海蛰素A(1)的高效不对称合成。沙海蛰素A(1)是从海洋海绵沙海蛰中分离得到的,对KB细胞表现出极强的细胞毒性,其IC50为pg/ml,在此背景下,还研究了1及其相关化合物的几种立体异构体之间的构效关系。
