Abstract
Helicobacter pylori (H. pylori) is a microaerophilic gastric pathogen and a major contributor to chronic atrophic gastritis, peptic ulcer, and gastric malignancies. The increasing prevalence of H. pylori infection and its related diseases, such as gastric cancer (GC), motivates medicinal chemists to seek for more effective multi-targeting drugs to prevent and treat H. pylori-related clinical complications. Benzimidazole, a hetero-aromatic bicyclic ring compound, has claimed a prominent role in medicinal chemistry owing to its broad range of biological activities, including, anti-bacterial, anti-viral, anti-diabetic, and anti-cancer activities. Studies highlight the promising therapeutic potential of benzimidazole derivatives in the treatment of H. pylori-related clinical complications such as gastric infection, gastritis, peptic ulcer, and GC. Accordingly, we here aimed to scrutinize the role of active molecules of benzimidazole derivatives as po tential anti-bacterial, anti-urease, anti-inflammatory, anti-ulcerative, and anti-cancer agents, which are expected to find their ways to the clinical setting sooner or later. Due to the role of structural moieties in determining the biological behaviors of benzimidazole derivatives, we explored the structure-activity relationship (SAR) of these compounds to further expand the scope of design of and research on new drugs against H. pylori-related diseases.
