Cucurbitacin IIb alleviates colitis via regulating gut microbial composition and metabolites.

ABSTRACT: Cucurbitacin IIb, a member of the triterpenoid family, exerts beneficial effects on intestinal diseases, including enteritis and bacillary dysentery. However, its effects and mechanisms of action on colitis have not yet been explored. In this study, we used a mouse model of dextran sulfate sodium (DSS)-induced colitis and explored the effects of cucurbitacin IIb on colitis symptoms, inflammatory responses, microbiota, and metabolite profiles. The results showed that cucurbitacin IIb alleviated colitis symptoms including body weight loss, an increase in the disease activity index, and elevated levels of myeloperoxidase and eosinophil peroxidase content. Additionally, it ameliorated intestinal morphology impairment, reduced the phosphorylation of NFκB protein, and mitigated accumulation of p
