Compound <strong>1</strong> was isolated from EK for the first time, while compounds <strong>2</strong>–<strong>6</strong> were reported for the first time.; The toxicity test results showed that compounds <strong>1</strong>–<strong>8</strong> did not produce zebrafish embryonic developmental toxicity at 12.5, 25, 50, and 100 μ M; The molecular docking results showed that the new compound had a good binding effect with inflammatory factors; The anti-inflammatory experiment results of RAW264.7 cells showed that compounds <strong>1</strong>–<strong>8</strong> did not produce cytotoxicity at 3, 10, 30, and 100 nM, but significantly increased cell viability and inhibited NO in cells, The levels of ROS, IL-6, IL-1β, TNF-α, and PGE2.</div></div><div><h3>Conclusion</h3><div>The research results indicate that compounds derived from EK can significantly reduce the expression levels of inflammatory cytokines and are safe, suggesting that EK has certain application prospects and can be further developed and utilized.</div></div>","PeriodicalId":15761,"journal":{"name":"Journal of ethnopharmacology","volume":"352 ","pages":"Article 120171"},"PeriodicalIF":4.8,"publicationDate":"2025-06-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144469997","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
