Name: Dovitinib (TKI-258)
Brand: Selleck Chemicals
SKU: S1018
Rating: 5 (54 reviews)

Cat. No.: S1018

Dovitinib (TKI-258, CHIR258) es un inhibidor de RTK multidirigido, que se dirige principalmente a los RTK de clase III (FLT3/c-Kit) con valores de IC50 de 1 nM/2 nM. También es potente contra los RTK de clase IV (FGFR1/3) y clase V (VEGFR1-4), exhibiendo valores de IC50 de 8-13 nM, mientras que muestra una menor potencia hacia InsR, EGFR, c-Met, EphA2, Tie2, IGF-1R y HER2 en ensayos libres de células. Fase 4.

In vitro	Dovitinib (TKI-258) potently inhibits the FGF-stimulated growth of WT and F384L-FGFR3-expressing B9 cells with IC50 of 25 nM. In addition, it inhibits proliferation of B9 cells expressing each of the various activated mutants of FGFR3. Interestingly, there are minimal observed differences in the sensitivity of the different FGFR3 mutations to this compound, with the IC50 ranging from 70 to 90 nM for each of the various mutations. IL-6-dependent B9 cells containing vector only (B9-MINV cells are resistant to its inhibitory activity at concentrations up to 1 μM. It inhibits cell proliferation of KMS11 (FGFR3-Y373C), OPM2 (FGFR3-K650E), and KMS18 (FGFR3-G384D) cells with IC50 of 90 nM (KMS11 and OPM2) and 550 nM, respectively. The compound inhibits FGF-mediated ERK1/2 phosphorylation and induces cytotoxicity in FGFR3-expressing primary MM cells. BMSCs does confer a modest degree of resistance with 44.6% growth inhibition for cells treated with 500 nM Dovitinib and cultured on stroma compared with 71.6% growth inhibition for cells grown without BMSCs. It inhibits proliferation of M-NFS-60, an M-CSF growth-driven mouse myeloblastic cell line with a median effective concentration (EC50) of 220 nM. Treatment of SK-HEP1 cells with this compound results in a dose-dependent reduction in cell number and G2/M phase arrest with reduction in the G0/G1 and S phases, inhibition of anchorage-independent growth and blockage of bFGF-induced cell motility. The IC50 for it in SK-HEP1 cells is approximately 1.7 μM. It also significantly reduces the basal phosphorylation levels of FGFR-1, FGFR substrate 2α (FRS2-α) and ERK1/2 but not Akt in both SK-HEP1 and 21-0208 cells. In 21-0208 HCC cells, it significantly inhibits bFGF-induced phosphorylation of FGFR-1, FRS2-α, ERK1/2 but not Akt.
Ensayo de quinasa	Ensayos de quinasa in vitro
Ensayo de quinasa	Los valores de concentración inhibitoria al 50 % (IC50) para la inhibición de RTKs por Dovitinib (TKI-258) se determinan en un formato de fluorescencia resuelta en el tiempo (TRF) o radiactivo, midiendo su inhibición de la transferencia de fosfato a un sustrato por la enzima respectiva. Los dominios quinasa de FGFR3, FGFR1, PDGFRβ y VEGFR1-3 se ensayan en 50 mM HEPES (ácido N-2-hidroxietilpiperazina-N′-2-etanosulfónico), pH 7.0, 2 mM MgCl₂, 10 mM MnCl₂, 1 mM NaF, 1 mM ditiotreitol (DTT), 1 mg/mL de albúmina sérica bovina (BSA), 0,25 μM de péptido sustrato biotinilado (GGGGQDGKDYIVLPI) y 1 a 30 μM de adenosín trifosfato (ATP) dependiendo del K_m para la enzima respectiva. Las concentraciones de ATP están en o justo por debajo del K_m. Para las reacciones de c-KIT y FLT3, el pH se eleva a 7.5 con 0,2 a 8 μM de ATP en presencia de 0,25 a 1 μM de péptido sustrato biotinilado (GGLFDDPSYVNVQNL). Las reacciones se incuban a temperatura ambiente durante 1 a 4 horas y el péptido fosforilado se captura en placas de microtitulación recubiertas de estreptavidina que contienen tampón de detención de reacción (25 mM EDTA [ácido etilendiaminotetraacético], 50 mM HEPES, pH 7.5). El péptido fosforilado se mide con el sistema DELFIA TRF utilizando un anticuerpo antifosfotirosina PT66 marcado con europio. La concentración de este compuesto para IC50 se calcula utilizando regresión no lineal con el software de análisis de datos XL-Fit versión 4.1 (IDBS). La inhibición de la actividad quinasa del receptor del factor estimulante de colonias-1 (CSF-1R), PDGFRα, receptor de insulina (InsR) y receptor del factor de crecimiento similar a la insulina 1 (IGFR1) se determina a concentraciones de ATP cercanas al K_m para ATP.
In vivo	Dovitinib (TKI-258) induces both cytostatic and cytotoxic responses in vivo resulting in regression of FGFR3-expressing tumors. It shows a dose- and exposure-dependent inhibition of target receptor tyrosine kinases (RTKs) expressed in tumor xenografts. This compound potently inhibits tumor growth of six HCC lines. Inhibition of angiogenesis correlated with inactivation of FGFR/PDGFRβ/VEGFR2 signaling pathways. In an orthotopic model, it potently inhibits primary tumor growth and lung metastasis and significantly prolonged mouse survival. Administration of Dovitinib results in significant tumor growth inhibition and tumor regressions, including large, established tumors (500-1,000 mm³).
