Tectorigenin (Tg) and tectoridin (Td) are the major compounds isolated from the rhizomes of iridaceous plant Belamcanda chinensis which is well known as a chinese traditional medicine for the treatment of inflammatory diseases. In this study we investigated whether tectorigenin and tectoridin can be applied to the suppression of interferon-$\gamma$ and lipopolysaccharide (IFN-$\gamma$/LPS)-induced inflammatory responses in macrophages. Anti-inflammatory activities of tectorigenin and tectoridin were compared with genistein (Ge), well known isoflavonoid as a phytoestrogen and regarded as an emerging anti-inflammatory agent. Both compounds showed low cytotoxic effect. In Raw 264.7 cells activated with $IFN-{\gamma}$/LPS, pre-treated tectorigenin was found to inhibit the expression of inducible nitric oxide synthase (iNOS), the production of nitric oxide (NO) and the secretion of interleukin (IL)-$1{\beta}$ dose-dependently. Tectorigenin also decreased the expression of cyclooxigenase (COX)-2 and the production of prostaglandin $E_2$ ($PGE_2$) in dose-dependent manner. These inhibitory effects of tectorigenin were found to be caused by the blocking of nuclear factor kappa-B (NF-${\kappa}B$) activation. Compared with genistein and tectoridin, tectorigenin showed significant inhibitory effect for almost anti-inflammatory tests in this study. All these results clearly demonstrated that tectorigenin appears to have the potential to prevent inflammation.
