Sauchinone, a lignan from Saururus chinensis, reduces tumor necrosis factor-α production through the inhibition of c-raf/MEK1/2/ERK 1/2 pathway activation
چکیده انگلیسی

We investigated the anti-inflammatory effects of sauchinone, a lignan isolated from Saururus chinensis, and the underlying mechanism in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. To assess the effects of sauchinone on LPS-induced macrophages activation, we measured the production of tumor necrosis factor (TNF)-α and macrophage inflammatory protein (MIP)-2, and activation of mitogen-activated protein kinases (MAPKs) including extracellular signal-regulated kinase (ERK) 1/2, c-Jun amino terminal kinases and p38 mitogen-activated protein kinase, and NF-κB activation in RAW264.7 cells. Sauchinone decreased the production of TNF-α, but not MIP-2 production in RAW264.7 cells stimulated with LPS. Sauchinone also decreased c-Raf-MEK1/2-ERK1/2 phosphorylation and NF-κB activation in RAW264.7 cells stimulated with LPS. Our results show that sauchinone inhibits LPS-induced TNF-α expression in macrophages by suppression of NF-κB activation via ERK1/2 pathway, which may constitute anti-inflammatory effects of sauchinone.
