摘要
Ulcerative colitis (UC) is a chronic and recurrent inflammatory bowel disease (IBD). There is a growing prevalence of UC, but current conventional drugs lack efficacy. Carthamin yellow (CY) is a flavonoid compound extracted from safflower that is widely used and has various pharmacological effects. In the present study, we established colitis models in mice via DSS and in Caco-2 cells via lipopolysaccharide (LPS). Our results showed that CY treatment attenuated the symptoms of colitis by decreasing colonic pathological damage and improving disease activity index (DAI) scores. Notably, we observed that CY treatment decreased the levels of proinflammatory cytokines (TNF-α, IL-6, and IL-1β) by inhibiting the NLRP3/Caspase-1/IL-1β and MAPK/NF-κB signaling pathways. Moreover, we verified that treatment with CY obviously improved intestinal barrier function in both DSS-induced mice and LPS-stimulated Caco-2 cells. Ferroptosis-related markers were assessed. CY attenuated DSS-induced colitis by inhibiting ferroptosis, as assessed by Fe
