Dovitinib (TKI-258) FLT3 억제제

제품 번호: S1018

Dovitinib (TKI-258, CHIR258)은 다중 표적 RTK 억제제로, 주로 1 nM/2 nM의 IC50 값으로 class III RTKs (FLT3/c-Kit)를 표적으로 합니다. 또한 class IV (FGFR1/3) 및 class V (VEGFR1-4) RTKs에 대해서도 8–13 nM의 IC50 값을 나타내며 강력한 활성을 보이지만, 무세포 분석에서는 InsR, EGFR, c-Met, EphA2, Tie2, IGF-1R 및 HER2에 대해 더 낮은 활성을 보입니다. 임상 4상.

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.

키나아제 분석
In vitro kinase assays
Dovitinib (TKI-258)에 의한 RTK 억제의 50% 억제 농도(IC50) 값은 각 효소에 의한 기질로의 인산염 전달 억제를 측정하는 시간 분해 형광(TRF) 또는 방사성 형식으로 결정됩니다. FGFR3, FGFR1, PDGFRβ 및 VEGFR1-3의 키나아제 도메인은 50 mM HEPES(N-2-hydroxyethylpiperazine-N′-2-ethanesulfonic acid), pH 7.0, 2 mM MgCl2, 10 mM MnCl2 1 mM NaF, 1 mM 디티오트레이톨(DTT), 1 mg/mL 소 혈청 알부민(BSA), 0.25 μM 비오틴화 펩타이드 기질(GGGGQDGKDYIVLPI) 및 각 효소의 Km에 따라 1~30 μM 아데노신 삼인산(ATP) 조건에서 분석됩니다. ATP 농도는 Km 수준이거나 그보다 약간 낮습니다. c-Kit 및 FLT3 반응의 경우, 0.25~1 μM의 비오틴화 펩타이드 기질(GGLFDDPSYVNVQNL)이 존재하는 상태에서 pH를 7.5로 높이고 0.2~8 μM의 ATP를 사용합니다. 반응물을 실온에서 1~4시간 동안 배양하고, 정지 반응 완충액(25 mM EDTA [ethylenediaminetetraacetic acid], 50 mM HEPES, pH 7.5)이 포함된 스트렙타비딘 코팅 마이크로타이터 플레이트에서 인산화된 펩타이드를 포획합니다. 인산화된 펩타이드는 유로퓸 표지 항포스포티로신 항체 PT66을 사용하여 DELFIA TRF 시스템으로 측정합니다. IC50을 위한 본 화합물의 농도는 XL-Fit 데이터 분석 소프트웨어 버전 4.1(IDBS)을 사용한 비선형 회귀 분석을 통해 계산됩니다. Colony-stimulating factor-1 receptor (CSF-1R), PDGFRα, 인슐린 수용체(InsR) 및 인슐린 유사 성장 인자 수용체 1(IGFR1) 키나아제 활성의 억제는 ATP에 대한 Km에 근접한 ATP 농도에서 결정됩니다.
생체 내(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).
