One-pot synthesis of a pentasaccharide with antibiotic activity against Helicobacter pylori

Abstract

A pentasaccharide that contains the alpha-1,4-GlcNAc mucin core two-branched O-glycan has been synthesized by a one-pot, two-step glycosylation strategy; this particular carbohydrate motif may provide protection against H. pylonri induced pathologies since the synthetic pentasaccharide inhibits cholesterol alpha-glucosyltransferase (IC50 of 0.47 mM).
