产品介绍
NVP-BVU972 是Met选择性抑制剂 (IC50:14 nM) ,它对其它的激酶抑制性较低。

产品描述

NVP-BVU972 is a selective and potent Met inhibitor with IC50 of 14 nM.

体内活性

NVP-BVU972有效抑制MET基因扩散的细胞系GTL-16,MKN-45和EBC-1的生长,IC50分别为66,82和32 nM。NVP-BVU972有效抑制MET激酶,而对其他激酶(包括最密切相关的激酶)RON抑制作用很低,IC50>1000 nM。NVP-BVU972抑制GTL-16细胞中组成型MET磷酸化,抑制A549细胞中HGF刺激的MET磷酸化,IC50分别为7.3和 22 nM。NVP-BVU972作用于表达野生型TPR-MET的BaF3细胞,剂量依赖性降低TPR-MET磷酸化。

激酶实验

TR-FRET biochemical assay with MET wild type and mutants: Enzyme activity is measured in a time resolved fluorescence resonance energy transfer (TR-FRET) assay, detecting tyrosine phosphorylation with a Eu-labelled anti-phospho-tyrosine antibody (fluorescence donor) and Allophycocyanin conjugated to Streptavidin (fluorescence acceptor) which binds to a biotin on the substrate peptide. For each variant, Km concentrations for ATP are determined in the absence of NVP-BVU972, and the ATP concentration in the kinase reaction is set to Km (4 μM for MET wt, 1 μM for MET Y1230H and MET F1200I). NVP-BVU972 is dissolved and diluted in DMSO and assayed in quadruplicate. Kinase reactions are carried out in 50 mM Tris-HCl pH 7.5, 8 mM MgCl2, 4 mM MnCl2, 0.05 % Tween 20, 0.05% bovine serum albumin, 0.1 mM EDTA, 1 mM DTT, 0.1 mM Na3VO4, in white 1536 well plates at room temperature. NVP-BVU972 and enzyme are incubated in a volume of 2 μL for 20 min, followed by the addition of 1 μL ATP and 1 μL biotinylated peptide substrate (PTK1) to final concentrations of Km and 1 μM, respectively. Enzyme concentrations in the reactions are 5 nM for MET wt, and 4 nM for the F1200I and Y1230H variants. After 90 min, reactions are stopped by addition of 1 μL stop/detection solution to reach final concentrations of 10 mM EDTA, 3.5 nM Eu-labelled antiphospho-tyrosine antibody PY20, and 10 nM Streptavidin Allophycocyanin. Time resolved fluorescence resonance energy transfer is measured in an Envision plate reader (excitation 320 nm, emission 615 nm and 665 nm).

细胞实验

BaF3 cells containing TPR-MET or various mutants thereof are grown in RPMI 1640 medium containing 10% fetal calf serum. For maintenance of parental BaF3 cells the medium is additionally supplemented with 10 ng/mL interleukin-3 (IL-3). For proliferation assays, BaF3 cells are seeded on 96-well-plates in triplicates at 104 cells per well and incubated with various concentrations of NVP-BVU972 for 72 hours followed by quantification of viable cells using a resazurin sodium salt dye reduction readout. IC50 values are determined with the XLFit Excel Add-In using a 4-parameter dose response model.(Only for Reference)
