To investigate the anti-inflammatory effects of the total flavonoids from Saussurea involucrata on lipopolysaccharides (LPS)-stimulated murine RAW264.7 macrophages and explore its underlying mechanism of action. Total flavonoids from Saussurea involucrata were extracted using chromatog. column method. Cell viability was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay. The production of nitric oxide was detected by Griess assay and the release of cytokines (IL-10 and TNF-α) and chemokines (MCP-1, MIP-1a, and CCL5/RANTES) was determined by ELISA to evaluate the anti-inflammatory activity of total flavonoids from Saussurea involucrata. Moreover, nuclear translocation of p65, c-Jun, and IRF3 was detected by immunofluorescence microscopy and Western blotting anal. was performed to determine the expression of related proteins. Total flavonoids extracted from Saussurea involucrata were 751.5 mg/g and the content of rutin was 506.5 mg/g. The production of inflammatory mediators including nitric oxide, cytokines, and chemokines was effectively inhibited by total flavonoids from Saussurea involucrata. Meanwhile, total flavonoids also suppressed the nuclear translocation of p65, c-Jun, and IRF3 in LPS-stimulated RAW264.7 cells. The LPS-induced expression of iNOS and COX-2 was remarkably reduced by treatment with total flavonoids from Saussurea involucrata. Moreover, total flavonoids decreased the expression levels of p-IKKα/β, p-TBK1, p-p38, p-ERK, p-JNK, p-p65, p-c-Jun, and p-IRF3 in LPS-exposed RAW264.7 macrophages. Total flavonoids from Saussurea involucrata potentially inhibit the secretion of pro-inflammatory mediators, which may be related to inhibition of p65, c-Jun, and IRF3 signaling pathways in LPS-stimulated RAW264.7 cells. This study involved multiple reactions and reactants, such as 1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9Computed Properties of C16H10O7).
1,8,9-Trihydroxy-3-methoxy-6H-benzofuro[3,2-c]chromen-6-one (cas: 524-12-9) belongs to benzofurans derivatives. Benzofuran is the “”parent”” of many related compounds with more complex structures. For example, psoralen is a benzofuran derivative that occurs in several plants. Benzofurans are stable towards alkali and readily polymerize on treatment with sulfuric acid, due to which they are useful for the preparation of low cost chemically relatively inert resins.Computed Properties of C16H10O7
