Werkingsmechanisme (Mechanism of Action)

Targets/IC₅₀/Ki	Ribonucleotide reductase (Cell-free assay) 65 nM
In vitro	Clofarabine wordt efficiënt in cellen getransporteerd via twee faciliterende of equilibratieve nucleosidetransporters, hENT1 en hENT2, en een concentratieve nucleosidetransporter, hCNT253. Deze verbinding wordt op stapsgewijze wijze gefosforyleerd door cytosolische kinasen tot de nucleotide-analogen Clofarabine 5′-mono-, di- en trifosfaat na binnenkomst in cellen, waarbij Clofarabine trifosfaat de actieve vorm is. Clofarabine 5′-mono-, di- en trifosfaat zijn geen substraten voor nucleosidetransporters en moeten enzymatisch worden omgezet door 5′-nucleotidase terug naar hun gedefosforyleerde nucleosidevorm voor transport uit de cel. Dit verbindingstrifosfaat is een krachtige remmer van ribonucleotide reductase (IC50 = 65 nM), vermoedelijk door binding aan de allosterische plaats op de regulerende subeenheid. Er is ook aangetoond dat het direct op mitochondriën werkt door het transmembraanpotentiaal te veranderen met vrijlating van cytochroom c, apoptose-inducerende factor (AIF), apoptose protease-activerende factor 1 (APAF1) en caspase 9 in het cytosol. Deze chemische stof vertoont een sterke in vitro groeiremming en cytotoxische activiteit (IC50-waarden = 0,028–0,29 μM) in een breed scala aan leukemie- en solide tumorcellijnen. Het is aangetoond dat het de activiteit van dCK in HL60-cellen verhoogt, en de vorming van de mono-, di- en trifosfaten van ara-C in K562-cellen verhoogt36. Deze verbinding (10 μM) remt de reparatie geïnitieerd door 4-hydroperoxycyclofosfamide (4-HC), waarbij de remming piekt bij intracellulaire concentraties van 5 μM in chronische lymfatische leukemie (CLL) lymfocyten. Het (10 μM) gecombineerd met 4-hydroperoxycyclofosfamide (4-HC) produceert meer dan additieve apoptotische celdood dan de som van elk afzonderlijk. Deze chemische stof (1 μM) gecombineerd met ara-C (10 μM) resulteert in een biochemische modulatie van ara-CTP en synergetische celdoding in K562-cellen.
In vivo	Intraperitoneaal toegediende Clofarabine heeft significante activiteit tegen een breed scala aan humane tumorxenografts die subcutaan zijn geïmplanteerd in athymische naakte muizen of muizen met ernstige gecombineerde immuundeficiëntie.
