Description
Sorafenibisaninhibitorofc-Raf,Ret,andVEGFR2thatiscurrentlyusedclinicallytotreatrenalcellcarcinomaandhepatocellularcarcinoma,aswellasotheradvancedcancers.Sorafenibexhibitsanticancerchemotherapeutic,anti-angiogenic,andimmunosuppressiveactivities.Inosteosarcomacells,sorafenibinhibitscellproliferationbydownregulatingexpressionofERKandVEGFR2andinhibitingphosphorylationofVEGFR2,RET,andMEK1.Incellularandanimalmodelsoflymphoma,sorafenibinhibitsphosphorylationofMAPKsandPI3K/Akt,decreasingvesseldensityandincreasingapoptoticcelldeath.Sorafenibalsoinhibitstheepithelial-to-mesenchymaltransition(EMT)inepithelialcellsandpotentiateshistoneacetylation.Inhepatomacells,thiscompounddecreaseslevelsofenhancerofzestehomolog2(EZH2)andinhibitshistonemethyltransferase(HMT)activity,inducingapoptosis.Inanimalmodels,sorafenibinhibitstumorgrowth,increasestumor-specificTcells,anddecreasesCD8+andTregTcellfunctionsbyinducingTcellapoptosis.Additionally,sorafenibinhibitsphosphorylationofSTAT3/5.
