Description
Summary:Rheumatoid arthritis (RA) is a chronic autoimmune disease, characterized by activated M1-like macrophage in the joint. Kitag ( ) is a traditional medicinal plant that has long been used to treat RA and other immune diseases in China. Fractions of were separated based on polarity. Anti-RA activity of the fractions were screened by LPS-stimulated RAW264.7 macrophage . The major active compounds were identified by UPLC-MS and quantified by HPLC. The anti-RA effects of the active fraction was evaluated in complete freund's adjuvant (CFA)-induced arthritis and collagen-induced arthritis (CIA) mouse models and LPS-stimulated macrophage . Sesquiterpene lactones-enriched fraction from (SL-XM) exhibited the strongest anti-RA activity among all components . Five major constituents i.e., Xanthinosin (1), Xanthatin (2), Mogolide D (3), Mogolide E (4), and Mogolide A (5) were identified as major compounds of SL-XM. SL-XM ameliorated symptoms of CFA and CIA induced arthritis mice model. Furthermore, SL-XM treatment inhibited LPS-induced M1 macrophages polarization. In addition, SL-XM inhibited the phosphorylation of NF-κB and MAPK signaling pathways in LPS-induced macrophage and CIA-challenged mice. The main anti-RA active fraction of may be the Sesquiterpene lactones, which includes five key compounds. SL-XM may exert its anti-RA effect by suppressing M1 macrophage polarization the NF-κB and MAPK signaling pathway.
