Total synthesis of caminoside B, a novel antimicrobial glycolipid isolated from the marine sponge Caminus sphaeroconia

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 (IC50 = 20 μM) 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.
