DCC-2036(Rebastinib)

Rebastinib (DCC-2036) is a conformational control Bcr-Abl inhibitor for Abl1WT and Abl1T315I with IC50 of 0.8 nM and 4 nM, also inhibits SRC, KDR, FLT3, and Tie-2, and low activity to seen towards c-Kit.
DCC-2036 is a member of the class of ureas that is urea in which one of the nitrogens bears a 3-tert-butyl-1-(quinolin-6-yl)-1H-pyrazol-5-yl substituent, while the other bears a 2-fluoro-4-{[2-(methylcarbamoyl)pyridin-4-yl]oxy}phenyl substituent. It has a role as a tyrosine kinase inhibitor. It is a member of quinolines, a pyridinecarboxamide, a member of pyrazoles, an organofluorine compound and a member of phenylureas.|Rebastinib has been used in trials studying the treatment of Chronic Myeloid Leukemia. It is an inhibitor of Tie2 tyrosine kinase receptor and an antineoplastic agent.|Rebastinib is an orally bioavailable small-molecule inhibitor of multiple tyrosine kinases with potential antineoplastic activity. Upon oral administration, rebastinib binds to and inhibits the Bcr-Abl fusion oncoprotein by changing the conformation of the folded protein to disallow ligand-dependent and ligand-independent activation; in addition, this agent binds to and inhibits Src family kinases LYN, HCK and FGR and the receptor tyrosine kinases TIE-2 and VEGFR-2. Rebastinib may exhibit more potent activity against T315I Bcr-Abl gatekeeper mutant kinases than other Bcr-Abl kinase inhibitors. The TIE-2 and VEGFR-2 receptor tyrosine kinases regulate angiogenesis, respectively, while the Src family kinases Abl, LYN, and HCK Src regulate a variety of cellular responses including differentiation, division, adhesion, and the stress response.
