Abstract
Helicobacter pylori (H. pylori) infection is characterized by the complex interplay between H. pylori and gastric disorders. It has been established that NOD1 can be activated by the peptidoglycan (PGN) present in the cell wall of H. pylori, serving as a key mediator of inflammation and initiating the RIP2/NF-κB and MAPK inflammatory signaling pathways. In this article, we reported on the development of a 2-chloroquinazolin-4-ol derivative 66 as a potent and selective antagonist of both human and mouse NOD1, which effectively inhibited the expression of inflammatory cytokines (IL-6, TNF-α) and chemokines (CXCL1, CXCL8) in immune and epithelial cells, as well as inflammatory cytokines (KC, IL-6) in a H. pylori-induced murine model of gastritis following oral administration. This study laid a foundation for treating gastritis induced by H. pylori infection.
