Abstract

Helicobacter pylori is the primary bacterium in the development of gastric cancer; thus, its eradication for the prevention and management of peptic ulcers is of utmost importance. Most primary or unexplained peptic ulcers are brought on by Helicobacter pylori infection, which also causes chronic inflammation. The lack of therapeutic compliance, antibiotic resistance, and the breakdown of antibiotics at gastric pH all contribute to the current eradication rates. Therefore, a recent area of focus is the hunt for novel therapeutics with great selectivity against H. pylori.

This review focuses on elucidating the landscape of anti-H. pylori compounds derived from both synthetic drug design programs and natural sources. Emphasis is placed on understanding the structure-activity relationships of these compounds and their mechanisms of action.

Furthermore, the potential of drug repurposing strategies to combat H. pylori infection is explored. By providing a comprehensive overview of major classes of anti-H. pylori compounds, this study aims to guide the development of new medications for the treatment of Helicobacter pylori infection. Ultimately, this review highlights promising avenues for future research and therapeutic interventions in the management of H. pylori -associated gastric cancer.
