Dovitinib (TKI-258) FLT3 inhibitor

N. Cat.: S1018

Dovitinib (TKI-258, CHIR258) is a multitargeted RTK inhibitor, primarily targeting class III RTKs (FLT3/c-Kit) with IC50 values of 1 nM/2 nM. It is also potent against class IV (FGFR1/3) and class V (VEGFR1-4) RTKs, exhibiting IC50 values of 8–13 nM, while showing lower potency toward InsR, EGFR, c-Met, EphA2, Tie2, IGF-1R, and HER2 in cell-free assays. Phase 4.

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.

Saggio chinasico
Saggi chinasici in vitro
I valori della concentrazione inibitoria del 50% (IC50) per l'inibizione delle RTK da parte di Dovitinib (TKI-258) sono determinati in un formato di fluorescenza risolta nel tempo (TRF) o radioattivo, misurando la sua inibizione del trasferimento di fosfato a un substrato da parte del rispettivo enzima. I domini chinasici di FGFR3, FGFR1, PDGFRβ e VEGFR1-3 sono saggiati in 50 mM HEPES (acido N-2-idrossietilpiperazina-N′-2-etansolfonico), pH 7,0, 2 mM MgCl2, 10 mM MnCl2, 1 mM NaF, 1 mM ditiotreitolo (DTT), 1 mg/mL di albumina sierica bovina (BSA), 0,25 μM di substrato peptidico biotinilato (GGGGQDGKDYIVLPI) e da 1 a 30 μM di adenosina trifosfato (ATP) a seconda del Km per il rispettivo enzima. Le concentrazioni di ATP sono a o appena al di sotto del Km. Per le reazioni di c-KIT e FLT3 il pH viene aumentato a 7,5 con 0,2-8 μM di ATP in presenza di 0,25-1 μM di substrato peptidico biotinilato (GGLFDDPSYVNVQNL). Le reazioni sono incubate a temperatura ambiente per 1-4 ore e il peptide fosforilato viene catturato su piastre microtiter rivestite di streptavidina contenenti tampone di blocco della reazione (25 mM EDTA [acido etilendiamminotetraacetico], 50 mM HEPES, pH 7,5). Il peptide fosforilato viene misurato con il sistema DELFIA TRF utilizzando un anticorpo anti-fosfotirosina PT66 marcato con Europio. La concentrazione di questo composto per l'IC50 è calcolata utilizzando la regressione non lineare con il software di analisi dati XL-Fit versione 4.1 (IDBS). L'inibizione dell'attività chinasica del recettore del fattore stimolante le colonie-1 (CSF-1R), PDGFRα, recettore dell'insulina (InsR) e recettore del fattore di crescita insulino-simile 1 (IGFR1) è determinata a concentrazioni di ATP vicine al Km per l'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).
