In this study, a DSS-induced mouse colitis model was utilized to investigate the ability of daucosterol (DAU) to alleviate colitis and its underlying mechanism of action. The experimental results showed that DAU could alleviate the clinical symptoms of colitis in mice, reduce the expression of proinflammatory cytokines (IL-1β, IL-6, and TNF-α) in mouse serum, and modulate the gut microbiota to alleviate DSS-induced colitis in mice. In conclusion, DAU has great potential in the prevention of colitis.  \nKeywords Daucosterol, Ulcerative colitis, DSS, Gut microbiota  \nIntroduction  \nThe incidence of inflammatory bowel disease (IBD), a chronic gastrointestinal disorder, is increasing annually [1]. Ulcerative colitis (UC) is a type of IBD. UC is a chronic inflammatory bowel disease characterized by colonic inflammation and ulceration [2], presenting with typical symptoms such as bloody diarrhea, abdominal pain, and tenesmus [3].  \nFlavonoids, a subgroup of polyphenolic compounds, possess anti-inflammatory and antioxidant activities, thereby alleviating colonic damage and contributing to the treatment of UC [4]. Daucosterol (DAU), a natural sterol compound, exhibits anti-inflammatory, antitumor, antioxidant, and immunomodulatory activities, as demonstrated by numerous studies [5–8]. Experimental evidence indicates that DAU attenuates cardiac dysfunction, improves ventricular remodeling, and reduces oxidative  \n†Jing Liang and Huihui Yang contributed equally to this work.  \n*Correspondence:  \nYanhong Yong  \n[yongyanhong-007@163.com](yongyanhong-007@163.com)  \n1College of Coastal Agricultural Sciences, Guangdong Ocean University, Zhanjiang 524088, China  \nstress in heart failure with preserved ejection fraction (HFpEF) mice by activating the PPARα pathway and suppressing NF-κB signaling, which is consistent with its established antioxidant function [9]. Furthermore, DAU has been shown to prevent alcohol-induced liver injury by exerting anti-inflammatory and antioxidant effects, which also mitigate oxidative stress and lipid accumulation in the liver in various chronic inflammatory diseases [10].  \nDAU is known to exhibit anti-inflammatory and antitumor activities. The evidence indicates that these compounds mediate cardioprotective effects through inactivation of the NOS-dependent NLRP3 inflammasome during preconditioning [11]. DAU also shows therapeutic potential for multiple myeloma (MM), where molecular docking was used to validate predicted regulatory associations with targets, and interaction patterns between DAU and key targets were analyzed [12]. In the protein‒protein interaction (PPI) network, DAU-targeted genes were significantly enriched in MM-related pathways, highlighting their therapeutic potential for MM. Moreover, DAU clearly plays a role in alleviating DSSinduced colitis; however, the impact of DAU on the intestinal microbiota remains unknown [13].  \n© The Author(s) 2025.
