摘要
Thepresentstudywasdesignedtoinvestigatetheanti-sepsiseffectsofphyscion8-O-β-glucopyranoside(POG)isolatedfromRumexjaponicasandexploreitspossiblepharmacologicalmechanisms.POGwasextractedfromR.japonicasbybioactivity-guidedisolationwiththeanti-sepsisagents.SurvivalanalysisinsepticmouseinducedbyLPSandheat-killedEscherichiacoliwereusedtoevaluatetheprotectiveeffectofPOG(40mg·kg~(-1),i.p.)onsepsis.CytokinesincludingTNF-α,IL-1βandIL-6inRAW264.7cellsinducedbyLPS(100ng·mL~(-1))weredeterminedbyELISA.Inaddition,theproteinsexpressionsofTLR2andTLR4weredeterminedbyWesternblottingassay.OurresultsdemonstratedthatPOG(40mg·kg~(-1),i.p.)possessedsignificantprotectiveactivityontheendotoxemicmice.ThePOGtreatment(20,40,and80μg·mL~(-1))significantlydecreasedtheTNF-α,IL-1βandIL-6inducedbyLPS(P<0.01)inaconcentration-dependentmanner.Furthermore,theTLR4andTLR2proteinswerealsodown-regulatedbyPOGat20(P<0.01),40(P<0.01),and80μg·mL~(-1)(P<0.01).ThepresentstudydemonstratedthatthePOGextractedfromR.japonicaspossessedsignificantanti-sepsiseffectonendotoxemicmice,andcanbedevelopedasanoveldrugfortreatingsepsisinthefuture.
