  • H. Pylori Lipopolysaccharide Outer Core Epitope
    Publication number: 20170129941
    Abstract: 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 ?1,6-glucan-containing Helicobacter pylori compound comprising the structure of Formula I: wherein R is a ?-DDHep-3-?-L-Fuc-3-?-GlcNAc trisaccharide substituted with an ?1,6-glucan linked to an ?1,3-DD-heptan, and wherein the last DD-Hep residue of ?1,3-DD-heptan is capped with ?-GlcNAc residue. Compositions comprising the compound, uses of the compound, and antibodies raised against the compound are also described.
