Cirsium japonicum var. ussuriense is known to have a variety of biological activities, including anti-infl ammatory, analgesic activity and antipyretic activity. In this study we investigated the role of polyacetylene compound, 1-Heptadecene-11, 13-diyne-8, 9, 10-triol (PA) from the root of Cirsium japonicum var. ussuriense as an immune-modulator. PA was evaluated as inhibitors of some macrophage functions involved in the infl ammatory process. We tested the effect of PA on the production of pro-infl ammatory cyokines, interleukin-1beta (IL-1β) and tumor necrosis factor-alpha (TNF-α), and nitric oxide (NO) in murine macrophage cell line, RAW264.7. There was no effect on cytokine production of macrophages by PA itself. However, PA inhibited lipopolysaccharide (LPS)-induced IL-1β and TNF-α production by macrophages at a dose dependent manner. PA also suppressed the NO production of macrophages by LPS. LPS-induced NF-κB activity was decreased by treatment of PA. Therefore, these results suggest that PA has anti-infl ammatory effect by inhibiting the NF-κB activation.
