Fisetinisaflavonoidfoundinvariousplantsourcesthatexhibitsneuroprotective,cognitionenhancing,antioxidative,immunosuppressive,anti-angiogenic,andanticanceractivities.InanimalmodelsofAlzheimer’sdisease,fisetindecreaseslevelsofp25andincreasesphosphorylationofERK,resultinginfewerdeficitsinlearningandmemory.Incellularmodels,fisetindecreaseslevelsofH2O2-generatedsuperoxideanions,hydroxylrADIcals,andROS.Fisetinactivatessirtuins,displayinganti-agingpotential.Inanimalmodels,thiscompoundpreventsdelayed-typehypersensitivityreactions;inrelatedcellularmodels,fisetininhibitsTh1/Th4cytokineproduction,activationofNF-κB,andsignalingbynuclearfactorofactivatedTcells(NFAT).Invariouscelllines,fisetininhibitsmatrixmetalloproteinases1,3,7,9,and14,inhibitingtube/vesselformationandcellproliferation.Innasopharyngealcarcinomacells,fisetininhibitstheepithelial-to-mesenchymaltransition(EMT),preventingcellmigrationandinvasion.ThiscompoundalsoinhibitstopoisomerasesIandII.
