Mécanisme daction

Targets/IC₅₀/Ki	Ribonucleotide reductase (Cell-free assay) 65 nM
In vitro	Le Clofarabine est efficacement transporté dans les cellules via deux transporteurs de nucléosides facilitants ou équilibratifs, hENT1 et hENT2, et un transporteur de nucléosides concentratif, hCNT253. Ce composé est phosphorylé de manière progressive par les kinases cytosoliques en analogues nucléotidiques clofarabine 5′-mono-, di- et triphosphate après l'entrée dans les cellules, le Clofarabine triphosphate 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 nucléosidique déphosphorylée pour être transportés hors de la cellule. Ce composé triphosphate 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 modifiant le potentiel transmembranaire avec libération de cytochrome c, du facteur induisant l'apoptose (AIF), du facteur 1 activant la protéase d'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 d'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 à des 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	Le Clofarabine administré par voie intrapéritonéale présente une activité significative contre une grande variété de xénogreffes tumorales humaines implantées sous-cutanément chez des souris nues athymiques ou des souris présentant un déficit immunitaire combiné sévère.
