Biological Activity |
Potent inhibitor of c-MET and anaplastic lymphoma kinase (ALK) (cell IC50 values are 8.0 and 20 nM respectively). Selective for c-MET and ALK against >120 different kinases. Displays antitumor efficacy in multiple tumor models; inhibits c-MET-dependent proliferation, migration and invasion of human tumor cells in vitro. Orally bioavailable. |
Mechanism of action |
Crizotinib is an inhibitor of receptor tyrosine kinases including ALK, Hepatocyte Growth Factor Receptor (HGFR, c-Met), and Recepteur d’Origine Nantais (RON). Translocations can affect the ALK gene resulting in the expression of oncogenic fusion proteins. The formation of ALK fusion proteins results in the activation and dysregulation of the gene's expression and signaling, which can contribute to increased cell proliferation and survival in tumors expressing these proteins. Crizotinib demonstrates concentration-dependent inhibition of ALK and c-Met phosphorylation in cell-based assays using tumor cell lines, and also demonstrates antitumor activity in mice bearing tumor xenografts that express EML4-or NPM-ALK fusion proteins or c-Met.Crizotinib is a multitargeted small molecule tyrosine kinase inhibitor, which had been originally developed as an inhibitor of the mesenchymal epithelial transition growth factor (c-MET); it is also a potent inhibitor of ALK phosphorylation and signal transduction. This inhibition is associated with G1-S phase cell cycle arrest and induction of apoptosis in positive cells in vitro and in vivo. Crizotinib also inhibits the related ROS1 receptor tyrosine kinase.
