| Outline of Final Research Achievements |
Helicobacter pylori lives in the surface mucous membrane of stomach, and binds to Lewis b sugar chain. The sugar chains containing the αGlcNAc residues show the growth inhibitory activity against H. pylori. Based on these two facts, this study achieves the synthesis of two types of αGlcNAc assemblies, and their antibacterial activities for H. pylori were clarified. In addition, this study accomplished the synthesis of the hybrid type sugars-assemblies composed of two kinds of sugars. Therefore, this study successfully leads to the development of the antibacterial agent for H. plylori involving the novel concept of “dual carbohydrate cluster effect”.
