| 英文摘要 | Swertia Mussotti is used as febrifuge, analgesic and to treat calculous cholecystitis, however, the underling mechanism remains unclear. This study investigates the therapeutic effect of the active fraction named iridoid and xanthone glycoside (IXG) extracted from S. mussotii on six animal models related to calculous cholecystitis and its complications, and to explore its potential target proteins. Four main compounds including swertiamarin (STR), sweroside (SRS), gentiopicroside (GPS) and mangiferin (MGR) were identified from the IXG by UHPLCTOF-MS. The in vivo experiments results confirmed that IXG significantly decreased the level of total bilirubin (TBIL), direct bilirubin (DBIL) and cyclooxygenase-2 (COX2) in calculous cholecystitis. IXG treatment dramatically reduced the number of twists and the time of clicking foot in 2nd phase induced by glacial acetic acid and formalin, however, no effect was showed on central pain established by hot plate test. IXG also significantly decreased the anal temperature induced by yeast and 2,4-dinitrophenol. These results indicated that IXG alleviate calculous cholecystitis and its clinical symptom. In addition, IXG suppressed the expression of Prostaglandin E2 (PGE2) in vitro. Mechanistically, COX2 was identified as the direct target of IXG in RAW264.7 cells, and downregulated the protein levels of COX2. The results confirmed that IXG ameliorates calculous cholecystitis and its clinical symptom (pain and fever) by suppressing the production of PGE2 through targeting COX2. |
