Mécanisme d'action (Mechanism of Action)

Targets/IC₅₀/Ki	Ribonucleotide reductase (Cell-free assay) 65 nM
In vitro	La Clofarabine est efficacement transportée dans les cellules via deux transporteurs de nucléosides facilitatifs ou équilibratifs, hENT1 et hENT2, et un transporteur de nucléosides concentratif, hCNT253. Ce composé est phosphorylé de manière progressive par des kinases cytosoliques en analogues nucléotidiques de Clofarabine 5'-mono-, di- et triphosphate après l'entrée dans les cellules, le triphosphate de Clofarabine étant la forme active. Les Clofarabine 5'-mono-, di- et triphosphate ne sont pas des substrats pour les transporteurs de nucléosides et doivent être convertis enzymatiquement par la 5'-nucléotidase en leur forme de nucléoside déphosphorylée pour être transportés hors de la cellule. Le triphosphate de ce composé est un puissant inhibiteur de la ribonucleotide reductase (IC50 = 65 nM), vraisemblablement en se liant au site allostérique sur la sous-unité régulatrice. Il a également été démontré qu'il agit directement sur les mitochondries en altérant le potentiel transmembranaire avec libération du cytochrome c, du facteur d'induction de l'apoptose (AIF), du facteur 1 d'activation de la protéase de l'apoptose (APAF1) et de la caspase 9 dans le cytosol. Ce produit chimique démontre une forte inhibition de la croissance in vitro et une activité cytotoxique (valeurs d'IC50 = 0,028–0,29 μM) dans une grande variété de lignées cellulaires de leucémie et de tumeurs solides. Il a été démontré qu'il augmente l'activité de la dCK dans les cellules HL60 et augmente la formation des mono-, di- et triphosphates de l'ara-C dans les cellules K56236. Ce composé (10 μM) inhibe la réparation initiée par le 4-hydroperoxycyclophosphamide (4-HC), l'inhibition atteignant un pic aux concentrations intracellulaires de 5 μM dans les lymphocytes de leucémie lymphoïde chronique (LLC). Il (10 μM) combiné au 4-hydroperoxycyclophosphamide (4-HC) produit une mort cellulaire apoptotique plus qu'additive que la somme de chacun seul. Ce produit chimique (1 μM) combiné à l'ara-C (10 μM) entraîne une modulation biochimique de l'ara-CTP et une destruction synergique des cellules K562.
In vivo	La Clofarabine administrée par voie intrapéritonéale a une activité significative contre une grande variété de xénogreffes tumorales humaines implantées sous-cutanément chez des souris nues athymiques ou des souris immunodéficientes combinées sévères.
