Abstract

Objectives: Spatholobi Caulis is the stem of Spatholobus suberectus Dunn., which has been used for treating menstrual disorders, anemia, and rheumatic arthralgia in traditional Oriental medicine, This study was conducted to evaluate the inhibitory effects of Spatholobi Caulis extract (SCE) on the production of nitric oxide (NO) and pro-inflammatory cytokines in LPS-activated Raw264,7 cells. Methods : Cell viability was determined by MIT assay. Relative levels of NO were measured with Griess reagent and pro-inflammatory cytokines were detected by ELISA Expression of iNOS and COX-2 proteins were determined by western blotting. Results : NO production and iNOS expression were increased by incubation with LPS for 24 h. However, the augmented NO was reduced by SCE in a dose-dependent manner. Expressions of iNOS and COX-2 were inhibited by the treatment with SCE, SCE also suppressed the production of pro-inflammatory cytokines, such as IL-1beta and IL-6. Conclusions : These results indicate that the MeOH extract of Spatholobi Caulis warrant further development as an anti-inflammatory agent for the treatment of Gram-negative bacterial infections.
