Magnolol inhibits lipopolysaccharide-induced inflammatory response by interfering with TLR4 mediated NF-[kappa]B and MAPKs signaling pathways

Ethnopharmacological relevance: Magnolia officinalis as a traditional Chinese herb has long been used for the treatment of anxiety, cough, headache and allergic diseases, and also have been used in traditional Chinese medicine to treat a variety of mental disorders including depression. Aim of the study: Magnolol, a hydroxylated biphenyl compound isolated from Magnolia officinalis, has been reported to have anti-inflammatory properties. However, the underlying molecular mechanisms are not well understood. The aim of this study was to investigate the molecular mechanism of magnolol in modifying lipopolysaccharide (LPS)-induced signal pathways in RAW264.7 cells.
