Uses
Compound used in treating melanoma
Uses
Dovitinib (TKI258, CHIR-258) is a multitargeted tyrosine kinase inhibitor of FLT3 and c-KIT with IC50 of 1 nM and 2 nM, respectively.
Uses
Dovitinib (TKI258, CHIR258) is a novel multi-target inhibitor for Flt3, c-Kit, FGFR1/3, VEGFR1/2/3, PDGFRα/β with IC50 of 1 nM, 2 nM, 8 nM/9 nM and 10 nM/13 nM/8 nM, 210 nM/27 nM respectively.
Uses
Dovitinib is a receptor tyrosine kinase inhibitor that targets vascular endothelial growth factor-2, basic fibroblast growth factor-1, and platelet-derived growth factor β receptors (IC50s = 65, 11, and 5 nM, respectively). By impairing these kinase signals, 1 μM dovitinib has been shown to prevent the growth and motility of pancreatic cancer cell lines (HPAF-II, BxPC-3, MiaPaCa2, and L3.6pl). At 0.04 μM, dovitinib can inhibit endothelial cell proliferation and motility. These antiangiogenic effects have been proposed to be the mechanism by which dovitinib inhibits hepatocellular carcinoma growth and metastasis. Dovitinib has been evaluated in clinical trials for the treatment of advanced solid tumors.
Description
Dovitinib (405169-16-6) is a potent kinase inhibitor. Inhibits FLT3 (IC50 = 1 nM), c-KIT (IC50 = 2 nM), FGFR (IC50 = 8 nM), VEGFR1/2/3 (IC50 = 10 nM), PDGFRβ (IC50 = 27 nM), and CSF-1R (IC50 = 36 nM).1 Active in cell culture and in whole animals. Dovitinib selectively blocks the growth B9 cells transformed by wild type, or activated mutant FGFR3. Induces apoptosis, or sensitizes cells to induction of apoptosis by other means in a variety of cancer cell lines.
Definition
ChEBI: 4-amino-5-fluoro-3-[5-(4-methyl-1-piperazinyl)-1,3-dihydrobenzimidazol-2-ylidene]-2-quinolinone is a N-arylpiperazine.
in vivo
the combination of tigatuzumab and tki258 inhibited huh-7 xenograft tumor growth [3]. tki258 reduced wm tumor progression [4].
