The first total synthesis of caminoside B, a novel marine antimicrobial glycolipid isolated from the marine sponge Caminus sphaeroconia, was developed. This marine small molecule inhibitor (IC(50)=20 microM) targeting type III secretory pathway of bacterial pathogenesis was assembled in good yield via a '2+2+1' strategy based on stereocontrolled construction of the four glycosidic linkages.
开发了首个全合成的caminoside B,一种从海洋海绵体Caminus sphaeroconia分离出的新型海洋抗菌糖脂。这种海洋小分子抑制剂(IC(50)= 20 microM)靶向细菌发病机理的III型分泌途径是通过基于两个糖苷键立体控制结构的'2 + 2 + 1'策略以高产量组装的。
