Description
DecitABIneisadeoxycytidineanalogthatisincorporatedintoDNA,inhibitingDNAmethyltransferase(DNMT1/3A/3B)activity.Thisdemethylatingagentisclinicallyusedtotreatmyelodysplasticsyndromes.Decitabine’sinhibitionofDNAmethyltransferasemaybemodulatedbyPKC.Decitabineexhibitsanticancerchemotherapeutic,immunomodulatory,andneurotoxicactivities.Incellularmodelsofacutemyelogenousleukemia(ALL),decitabinedemethylationpreventscancercellinactivationofTRAILsignaling,increasingapoptosisandcelldeath.Invivo,decitabinestimulatesincreasesincancertestisantigen-specificcytotoxic(CD8+)Tcellactivity.Indopaminergicneurons,thiscompoundinducesapoptosisandupregulationoftyrosinehydroxylaseandα-synuclein,suggestingcomplicationsforuseinsubjectswithParkinson’sdisease.DecitabinealsoinhibitsreplicationofHIVincellularmodelswithoutdisplayingcytotoxicity.Additionally,thiscompoundshowsbenefitinthetreatmentofsickle-cellanemiathroughitsstimulationoffetalhemoglobinproduction.
