Objective: To investigate the effect of isoimperatorin on histopathological and biochemical changes in acetic acid-induced colitis rats. Methods: Colitis was induced by intracolonic administration of acetic acid solution (4% v/v) in rats. Rats were divided into six groups including the sham group, the negative control group, the dexamethasone-treated group, and the groups treated with isoimperatorin (0.1, 1, and 10 mg/kg/d by gavage). The treatments were administered for three days and then colonic status was assessed by macroscopic, histopathological, and biochemical analyses. Results: Isoimperatorin significantly alleviated colonic damage in a dose-dependent manner and improved histological changes in rats with acetic acid-induced colitis. It also significantly reduced myeloperoxidase, TNF-α, IL-1β, and malodialdehyde levels. Conclusions: Isoimperatorin alleviates acetic acid-induced colitis in rats and may be a potential therapeutic agent for the treatment of colitis.
