Abstract:

Background: Panax ginseng has been used as a traditional medicine for various pathological conditions. Ginsenoyne C (GSC) is a polyacetylene, minor constituent. Objective: The objective of the present study was to determine the anti-inflammatory activities of GSC for the protection of inflammation. Materials and Methods: The effects of GSC on cell viability and nitric oxide (NO) production in lipopolysaccharide (LPS)–induced RAW 264.7 cells were investigated through MTT assay and the Griess reaction, respectively. The levels of inflammatory cytokines such as interleukin (IL-1β) and IL-6 and inducible NO synthase (iNOS), cyclooxygenase-2 (COX-2), and pERK were measured using enzyme-linked immunosorbent assay and Western blot analysis, respectively. Results: GSC suppressed NO production in LPS-induced RAW 264.7 cells. GSC suppressed the production of inflammatory mediators through downregulating phosphorylation of extracellular regulated kinases signaling in LPS-induced RAW 264.7. Conclusion: GSC has a potential therapeutic agent for protection of inflammation.
