Dovitinib

Dovitinib is a multi-targeted tyrosine kinase inhibitor with IC50s of 1, 2, 8/9, 10/13/8, 27/210 nM for FLT3, c-Kit, FGFR1/3, VEGFR1/2/3 and PDGFRα/β, respectively.

4-amino-5-fluoro-3-[5-(4-methyl-1-piperazinyl)-1,3-dihydrobenzimidazol-2-ylidene]-2-quinolinone is a N-arylpiperazine.|Dovitinib is an orally active small molecule that exhibits potent inhibitory activity against multiple RTKs involved in tumor growth and angiogenesis. Preclinical data show that dovitinib works to inhibit multiple kinases associated with different cancers, including acute myeloid leukemia (AML) and multiple myeloma. Chiron currently has three ongoing Phase I clinical trials for dovitinib.|Dovitinib is a benzimidazole-quinolinone compound and receptor tyrosine kinase (RTK) inhibitor with potential antineoplastic activity. Dovitinib binds to and inhibits the phosphorylation of type III-V RTKs, such as vascular endothelial growth factor receptor (VEGFR) and platelet-derived growth factor receptor (PDGFR) that promote tumor cell proliferation and survival in certain cancer cells. In addition, this agent also inhibits other members of the RTK superfamily, including fibroblast growth factor receptor 1 and 3, FMS-like tyrosine kinase 3, stem cell factor receptor (c-KIT), and colony stimulating factor receptor 1. This may further lead to a reduction of cellular proliferation and angiogenesis, and an induction of tumor cell apoptosis.

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.
