生物活性

Dovitinib (CHIR-258) is an orally active, potent multi-targeted tyrosine kinase (RTK) inhibitor with IC₅₀s of 1, 2, 36, 8/9, 10/13/8, 27/210 nM for FLT3, c-Kit, CSF-1R, FGFR1/FGFR3, VEGFR1/VEGFR2/VEGFR3 and PDGFRα/PDGFRβ, respectively. Dovitinib has potent antitumor activity.

体外研究

Dovitinib (CHIR-258) shows more than 10-fold inhibition InsR (IC50=2 μM), EGFR1 (IC50=2 μM), c-Met (IC50>3 μM), EphrinA2 (EphA2; IC50=4 μM), Tie2 (IC50=4 μM), IGFR1 (IC50>10 μM), and HER2 (IC50>10 μM).
Dovitinib (12.5-400 nM; 48 hours) potently inhibits the FGF-stimulated growth of WT and F384L-FGFR3-expressing B9 cells with IC50 values of 25 nM.
Dovitinib (100, 500 nM; 96 hours) inhibits FGF-mediated ERK1/2 phosphorylation and induces apoptosis of FGFR3-expressing human myeloma cell lines.
Dovitinib (72 hours) inhibits cell proliferation of KMS11 (FGFR3-Y373C), OPM2 (FGFR3-K650E), and KMS18 (FGFR3-G384D) cells with IC50 of values of 90 nM (KMS11 and OPM2) and 550 nM, respectively.
Dovitinib (100 nM) augments Dexamethasone (0.5 μM) cytotoxicity in KMS11 cells.
Dovitinib 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.
Dovitinib enhances the BMP-2-induced alkaline phosphatase (ALP) induction, which is a representative marker of osteoblast differentiation. Dovitinib also stimulates the translocation of phosphorylated Smad1/5/8 into the nucleus and phosphorylation of mitogen-activated protein kinases, including ERK1/2 and p38.
Dovitinib strongly inhibits both the interaction of TNIK with ATP (K_i, 13 nM) and the activation of Wnt signaling effectors such as β-catenin and TCF4. Dovitinib also induces caspase-dependent apoptosis in IM-9 cells without significant cytotoxicity in PBMCs.
