Abstract: A method for directly inhibiting proliferation of Helicobacter pylori bacteria, that includes administering to a subject infected with Helicobacter pylori an N-acetylglucosaminyl beta-linked monosaccharide represented by: GlcNAcl-beta-O—Y where Y is an alkyl group, an alkoxyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, a heteroaryl group, a carboxyl group, or an alkoxycarbonyl group.

Abstract: A method for inhibiting proliferation of Helicobacter pylori including a compound that can simply be mass-produced, can specifically inhibit the proliferation of H. pylori, which has high safety and never generates any resistant bacteria, as well as a diet of a food or beverage, and a pharmaceutical preparation containing the proliferation inhibitor of Helicobacter pylori. The proliferation inhibitor of Helicobacter pylori comprises an alpha-N-acetyl-glucosaminyl bond-containing monosaccharide derivative represented by the following chemical formula (1) GlcNAc1-alpha-O—Y ??(1) (in the formula (1), Y is a straight-, branched- or cyclic-aliphatic hydrocarbon group having 1 to 27 carbon atoms or a straight-, branched- or cyclic-acyl group having 1 to 27 carbon atoms). The diet of the food, the beverage or the pharmaceutical preparation comprises the proliferation inhibitor of Helicobacter pylori.

Abstract: A proliferation inhibitor of H. pylori bacteria comprising a compound that can specifically inhibit the proliferation of H. pylori bacteria, which does not generate bacterium resistant, can be eaten, drunken or administrated safely for a long period of time, can be simply mass-manufactured and can be used for foods and beverages or pharmaceutical preparation. The proliferation inhibitor of H. pylori bacteria comprises an N-acetylglucosaminyl beta-linked monosaccharide derivative represented by the following chemical formula (1): GlcNAc1-beta-O—Y??(1) wherein Y is an alkyl group, an alkoxyl group, an alkenyl group, an alkynyl group, an aralkyl group, an aryl group, a heteroaryl group, a carboxyl group or an alkoxycarbonyl group.
