The present study shows that this compound causes a significant inhibition of inflammatory mediators in selected in vitro models: Thus, 1 was identified as a:potent inhibitor of tumor necrosis factor a (TNF alpha) gene expression and secretion by blocking the translocation of nuclear factor kappa B (NF-kappa B) from the cytoplasm to the nucleus in macrophages derived from a THP-1 human monocyte cell line. The NF-kappa B activity reduction resulted in the inhibition of cyclooxygenase 2 (COX-2) gene expression. Compound Cads as a COX-2 and COX-1 inhibitor with higher selectivity toward COX-2 than indomethacin. Pretreament of cells by 1 shifted the peak in an regulatory gene zinc finger protein 36 (ZFP36) expression assay. This natural product has noticeable anti-inflammatory properties suggesting that 1 potentially could be Used for development as a nonsteroidal anti inflammatory drug leadArticleWOS:0002897423000117995539448910.1021/np100638h
