Sinensetin is one of the polymethoxyflavones (PMFs) having five methoxy groups on the basic benzo-γ-pyrone skeleton with a carbonyl group at the C4 position. We investigated in this study the anti-inflammatory activity of sinensetin in lipopolysaccharide (LPS)-stimulated RAW 264.7 cells. Sinensetin showed anti-inflammatory activity by regulating the protein level of inhibitor κB-α (IκB-α).
