生物活性
靶点	ALK ROS1, Ki:<0.025 nM ALK, IC50:24 nM
描述	c-Met, the prototypic member of a subfamily of RTKs, and its ligand HGF, are implicated in the progression of several human cancers and are attractive therapeutic targets. Activation of c-Met results in the binding and phosphorylation of adaptor proteins, such as Gab1, Grb2, Shc and c-Cbl and subsequent activation of signal transducers such as PI3K, Akt, PLC-γ, STAT and ERK1/2. Crizotinib is a potent and selective inhibitor of c-Met with Ki value of 4nM (measured by c-Met kinase activity) and ALK with IC50 value of 24nM (based on cell study). Antitumor activity of Crizotinib may be mediated by both direct effects on tumor cell growth or survival, as well as antiangiogenic mechanisms. It inhibited growth and induced apoptosis of human GTL-16 gastric carcinoma with IC50s of 9.7nM and 8.4nM, respectively, blocked the cell migration and invasion induced by HGF in NCI-H441 lung carcinoma cells with IC50 of 11nM and 6.1nM, as well as inhibited MDCK cell scattering with IC50 of 16nM. Treatment with Crizotinib resulted in inhibition on serum-stimulated HMVEC branching tubulogenesis, as well as inhibition on HGF-stimulated c-Met phosphorylation, cell survival and Matrigel invasion with IC50 values of 11nM, 14nM and 35nM, respectively, in HUVEC cells. And this two mechanism of anti-tumor effect also acted in tumor models. Oral administration of Crizotinib at dose of 6.25mg/kg, 12.5mg/kg and 50mg/kg showed tumor growth inhibition on 30%, 60% and 100% in c-Met–dependent GTL-16 tumor xenograft model with dose-dependent decrease in c-Met phosphorylation. The effect of Crizotinib on signal transduction pathways can be observed in tumors in vivo, as levels of phosphorylated c-Met, Akt, Erk, PLCE1 and STAT5 decreased in athymic mice bearing established GTL-16 xenografts orally administrated with Crizotinib at dose of 25 or 50mg/kg for 11 days^[1].
作用机制	Crizotinib preferentially binds to the ATP binding pocket of ALK in its inactive conformation.^[1]
