It has been reported that Scolopendra morsitans L.(SML) has beneficial effects on human health and diverse diseases. The purpose of this study was to investigate the anti-inflammatory effects of ether extract from Scolopendra morsitans L. on lipopolysaccharide(LPS)-induced inflammatory response. Thus, we examined the inhibitory effect of SML ether fraction on LPS-induced increase of inflammatory mediators(NO, iNOS, COX-2, and IκBα) and pro-inflammatory cytokines(TNF-α) in RAW 264.7 cells. In the present study, SML ether extract itself decreased cell viability in a dose dependent manner(> 100 μg/ml). In addition, LPS increased NO production, iNOS expression and phosphorylation of Iκ-Bα, which were blocked by the treatment of SML ether fraction in a dose dependent manner. Furthermore, the treatment of LPS increased TNF-α production. However, the pretreatment of SML ether fraction prevented the LPS-induced TNF-α production in dose dependant manner. Taken together, our results suggest that SML may be a beneficial drug against inflammatory diseases such as sepsis.
