Teprenone

Teprenone (CAS No.: 6809-52-5) is a gastroprotective anti-ulcer agent widely utilized in biomedical research as an inducer of heat shock proteins (HSPs), enabling investigation of cellular stress responses and mucosal defense mechanisms. It promotes the upregulation of multiple HSP family members, including Hsp70, Hsp27, Hsp90, Hsp22, and Hsp105, thereby enhancing protein homeostasis, cytoprotection, and cellular recovery under conditions of physiological and pathological stress. Through activation of HSP-associated signaling pathways, Teprenone strengthens endogenous defense systems, facilitates epithelial barrier maintenance, and modulates inflammatory responses, making it particularly valuable for studies of gastric mucosal protection, ulcer formation, and gastrointestinal injury repair. Its biological effects are often more pronounced under stress conditions, reflecting its role as a pharmacological preconditioning agent. In vitro and in vivo studies suggest activity across low micromolar to higher concentration ranges depending on cell type and experimental context, and it has also demonstrated broader protective effects in hepatic and neural tissues. Teprenone is commonly applied in cell-based assays and animal models to elucidate mechanisms of cytoprotection, stress adaptation, and tissue regeneration, with dosing and exposure parameters tailored to specific experimental objectives.
