N° Cat.S5243

Le Ruxolitinib Phosphate (INCB018424, INC424) est la forme sel de phosphate du Ruxolitinib. Le Ruxolitinib est le premier inhibiteur puissant et sélectif de JAK1/2 à entrer en clinique avec une IC50 de 3,3 nM/2,8 nM dans les essais sans cellules, une sélectivité >130 fois supérieure pour JAK1/2 par rapport à JAK3. Le Ruxolitinib tue les cellules tumorales par mitophagy toxique. Le Ruxolitinib induit l'autophagy et améliore l'apoptosis.

Mécanisme daction

Targets/IC₅₀/Ki	JAK2 (Cell-free assay) 2.8 nM JAK1 (Cell-free assay) 3.3 nM
In vitro	L'INCB018424 inhibe puissamment et sélectivement la signalisation et la prolifération médiées par JAK2V617F dans les cellules Ba/F3 et les cellules HEL. L'INCB018424 augmente nettement l'apoptose de manière dose-dépendante dans les cellules Ba/F3. L'INCB018424 (64 nM) entraîne un doublement des cellules avec des mitochondries dépolarisées dans les cellules Ba/F3. L'INCB018424 inhibe la prolifération des progéniteurs érythroïdes de donneurs normaux et de patients atteints de polyglobulie de Vaquez avec une IC50 de 407 nM et 223 nM, respectivement. L'INCB018424 démontre une puissance remarquable contre la formation de colonies érythroïdes avec une IC50 de 67 nM.
Kinase Assay	Essai de liaison
Kinase Assay	Les protéines recombinantes sont exprimées à l'aide de cellules Sf21 et de vecteurs de baculovirus et purifiées par chromatographie d'affinité. Les essais de JAK kinase utilisent un essai de fluorescence homogène résolue dans le temps avec le substrat peptidique (-EQEDEPEGDYFEWLE). Chaque réaction enzymatique est réalisée avec du Ruxolitinib ou un contrôle, l'enzyme JAK, 500 nM de peptide, de l'adénosine triphosphate (ATP ; 1mM), et 2% de diméthylsulfoxyde (DMSO) pendant 1 heure. La concentration inhibitrice à 50% (IC50) est calculée comme la concentration d'INCB018424 requise pour l'inhibition de 50% du signal fluorescent.
In vivo	L'INCB018424 (180 mg/kg, par voie orale, deux fois par jour) entraîne un taux de survie supérieur à 90 % au jour 22 dans un modèle de souris piloté par JAK2V617F. L'INCB018424 (180 mg/kg, par voie orale, deux fois par jour) réduit considérablement la splénomégalie et les niveaux circulants de cytokines inflammatoires, et élimine préférentiellement les cellules néoplasiques, ce qui prolonge significativement la survie sans effets myélosuppresseurs ou immunosuppresseurs dans un modèle de souris piloté par JAK2V617F. Le critère d'évaluation principal est atteint chez 41,9 % des patients du groupe Ruxolitinib, contre 0,7 % dans le groupe placebo, dans l'essai en double aveugle sur la myélofibrose. Le Ruxolitinib permet de maintenir la réduction du volume de la rate et une amélioration de 50 % ou plus du score total des symptômes. Au total, 28 % des patients du groupe Ruxolitinib (15 mg deux fois par jour) ont une réduction d'au moins 35 % du volume de la rate à la semaine 48 chez les patients atteints de myélofibrose, contre 0 % dans le groupe recevant la meilleure thérapie disponible. La longueur moyenne de la rate palpable a diminué de 56 % avec le Ruxolitinib, mais a augmenté de 4 % avec la meilleure thérapie disponible à la semaine 48. Les patients du groupe ruxolitinib ont une amélioration des mesures globales de la qualité de vie et une réduction des symptômes associés à la myélofibrose.
