Mechanism of Action

Targets/IC₅₀/Ki	c-Met ^[1] (Cell-free assay) 9 nM RON ^[1] (Cell-free assay) 68 nM Flk1 ^[1] (Cell-free assay) 200 nM
In vitro	PHA-665752 significantly inhibits c-Met kinase activity with K_i of 4 nM, and exhibits >50-fold selectivity for c-Met compared with various tyrosine and serine-threonine kinases. This compound potently inhibits the HGF-stimulated c-Met autophosphorylation with IC50 of 25-50 nM. It also significantly blocks HGF- and c-Met-dependent functions such as cell motility and cell proliferation with IC50 of 40-50 nM and 18-42 nM, respectively. In addition, this chemical potently inhibits HGF-stimulated or constitutive phosphorylation of mediators of downstream of c-Met such as Gab-1, ERK, Akt, STAT3, PLC-γ, and FAK in multiple tumor cell lines. ^[1] It inhibits cell growth in TPR-MET-transformed BaF3 cells with IC50 of <60 nM, and inhibits constitutive cell motility and migration by 92.5% at 0.2 μM. Inhibition of c-Met by this compound (0.2 μM) also induces cell apoptosis of 33.1% and G1 cell cycle arrest with cells in G1 phase increasing from 42.4% to 77.0%. It can cooperate with rapamycin to inhibit cell growth of TPR-MET-transformed BaF3 cells and non-small cell lung cancer H441 cells. ^[2]
Kinase Assay	In vitro enzyme assay
Kinase Assay	The c-Met kinase domain GST-fusion protein is used for the c-Met assay. The IC50 value of PHA-665752 for the inhibition of c-Met is based on phosphorylation of kinase peptide substrates or poly-glu-tyr in the presence of ATP and divalent cation (MgCl₂ or MnCl₂ 10-20 mM). The linear range (i.e., the time period over which the rate remains equivalent to the initial rate) is determined for c-Met, and the kinetic measurement and IC50 determination are performed within this range.
In vivo	Administration of PHA-665752 induces a dose-dependent tumor growth inhibition of S114 xenografts by 20 %, 39% and 68%, at dose of 7.5, 15, and 30 mg/kg/day, respectively. ^[1] This compound treatment significantly reduces the tumor growth of NCI-H69, NCI-H441 and A549 in mouse xenografts by 99%, 75%, and 59%, respectively. It also significantly inhibits angiogenesis by >85%, due to decreasing the production of vascular endothelial growth factor and increasing the production of the angiogenesis inhibitor thrombospondin-1. ^[3]

Frequently Asked Questions

Question 1:
I need to use it for intraperitoneal application in mice. Could you tell me the solvent you use, please?

Answer:
The highest concentration of this compound (S1070) in 4% DMSO+30% PEG 300+5% Tween 80+ddH2O is 5mg/ml. If you want to get higher concentration, the concentration of DMSO and PEG will be higher. For example, it can be dissolved in 8% DMSO+50% PEG 300+5% Tween 80+ddH2O at 10mg/ml clearly.
