- Abstract
A study on the anti-inflammatory activity of brown alga Sargassum siliquastrum led to the isolation of sargachromanol G (SG). In this study, the anti-inflammatory effect and the action mechanism of SG have been investigated in murine macrophage cell line RAW 264.7. SG dosedependently inhibited the production of inflammatory markers [nitric oxide (NO), inducible nitric oxide synthase (iNOS), prostaglandin E (PGE), and cyclooxygenase-2 (COX-2)] and pro-inflammatory cytokines [tumor necrosis factor-α (TNF-α), interleukin (IL)-1β, and IL-6] induced by LPS treatment. To further elucidate the mechanism of this inhibitory effect of SG, we studied LPS-induced nuclear factor-κB (NF-κB) activation and mitogen-activated protein kinases (MAPKs) phosphorylation. SG inhibited the phosphorylation IκB-α and NF-κB (p65 and p50) and MAPK (ERK1/2, JNK, and p38) in a dose dependent manner. These results suggest that the anti-inflammatory activity of SG results from its modulation of pro-inflammatory cytokines and mediators via the suppression of NF-κB activation and MAPK phosphorylation.
