<i>H. pylori </i>lipopolysaccharide outer core epitope

摘要

Helicobacter pylori, one of the most common human pathogens, is associated with the development of human chronic gastritis, peptic ulcers and gastric cancer. The invention relates to a α1,6-glucan-containing Helicobacter pylori compound comprising the structure of Formula (I): wherein R is a α-DDHep-3-α-L-Fuc-3-β-GlcNAc trisaccharide substituted with an α1,6-glucan linked to an α1,3-DD-heptan, and wherein the last DD-Hep residue of α1,3-DD-heptan is capped with β-GlcNAc residue. Compositions comprising the compound, uses of the compound, and antibodies raised against the compound are also described.;
