Sofalcone

Sofalcone (CAS No.: 64506-49-6) is a synthetic chalcone-derived gastric mucosal protective agent widely utilized in biomedical research focused on gastrointestinal inflammation, ulceration, and host–pathogen interactions. It exhibits multifaceted pharmacological activity, including inhibition of Helicobacter pylori growth and interference with key virulence-associated processes such as bacterial adherence, vacuolating toxin production, and induction of interleukin-8 secretion in gastric epithelial cells. Mechanistically, Sofalcone modulates inflammatory signaling pathways by suppressing the production of pro-inflammatory mediators including nitric oxide, tumor necrosis factor-α, and monocyte chemoattractant protein-1, while robustly inducing the cytoprotective enzyme heme oxygenase-1 in gastric epithelium, indicating involvement of oxidative stress–responsive pathways. Additionally, it promotes vascular endothelial growth factor expression, supporting angiogenesis and tissue repair processes relevant to ulcer healing. In vitro studies typically demonstrate activity in the low to mid micromolar range, consistent with its modulation of inflammatory and cytoprotective signaling networks. Sofalcone is commonly employed in cell-based assays of gastric epithelial function, inflammation, and bacterial infection, as well as in animal models of gastric ulceration and mucosal injury, where dosing regimens vary according to experimental design and therapeutic endpoints, making it a valuable tool for investigating mechanisms of mucosal defense and for anti-ulcer drug discovery.
