The inhibitory effect of BMS-777607 on survival and proliferation of L3.6pl and CSCs＋24/44/ESA was determined by the clonogenic assay. Brieﬂy, L3.6pl cells (6,000 cells/well) in minimum essential media (MEM) with 5% FBS were cultured in duplicate in a 24-well plate and then treated with different amounts of BMS-777607 for 12 days. CSCs＋24/44/ESA in stem cell culture media were incubated for 18 days in the ultra-low attachment culture plate coated with a thin layer of 0.2% of agarose to facilitate cell anchored growth. Clonogenic cells were stained with Hema-3 staining solution (Fisher Scientiﬁc), photographed using an Olympus BK71 microscope equipped with CCD camera, and counted. The number of clonogenic growth from individual groups is presented.

BMS-777607 increases p21/WAF1 and survivin expression but down-regulates Rb expression. T-47D and ZR-75-1 cells (2×106 cells in 60 mm diameter culture dish) were treated with 5 mM BMS-777607 for different time intervals. Cellular proteins (50 mg per sample) from cell lysates were subjected to Western blot analysis using individual antibodies speciﬁc to p53, p21/WAF1, survivin, regular and phospho-Rb. B-actin was used as the loading control.

|Description||BMS-777607 is a Met-related inhibitor for c-Met, Axl, Ron and Tyro3 with IC50 of 3.9 nM, 1.1 nM, 1.8 nM and 4.3 nM in cell-free assays, 40-fold more selective for Met-related targets versus Lck, VEGFR-2, and TrkA/B, and more than 500-fold greater selectivity versus all other receptor and non receptor kinases. Phase 1/2.|
|Features||A potent inhibitor of the Met family, and >40-fold selectivity vs. Lck, VEGFR2, and TrkA/B and >500-fold selective vs. other receptor and non-receptor kinases.|
BMS-777607 is a selective ATP-competitive Met kinase inhibitor which potently blocks the autophosphorylation of c-Met with IC50 of 20 nM in GTL-16 cell lysates, and demonstrates selective inhibition of proliferation in Met-driven tumor cell lines, such as GTL-16 cell line, H1993 and U87.  BMS-777607 inhibits hepatocyte growth factor (HGF)-triggered c-Met autophosphorylation with IC50 of <1 nM in PC-3 and DU145 prostate cancer cells. BMS 777607 has little effect on tumor cell growth, but exhibits inhibitory effect on HGF-induced cell scattering in PC-3 and DU145 cells, with almost complete inhibition at 0.5 μM. BMS 777607 also suppresses stimulated cell migration and invasion in a dose-dependent fashion (IC50 < 0.1 μM) in both cell lines.  Application of BMS 777607 (~10 μM) to the highly metastatic murine KHT cells for 2 hours potently eliminates basal levels of autophosphorylated c-Met with IC50 of 10 nM without affecting the total c-Met, leading to dose-dependent inhibition of phosphorylation of downstream signaling molecules including ERK, Akt, p70S6K and S6. Treatment with BMS-777607 (~1 μM) for 24 hours potently inhibits the KHT cell scatter, motility and invasion at doses in the nanomolar range which consists with MET gene knockdown, and modestly affects cell proliferation and colony formation. 
|In vivo||Oral administration of BMS 777607 (6.25-50 mg/kg) significantly reduces tumor volumes of the GTL-16 human tumor xenografts in athymic mice with no observed toxicity.  Administration of BMS 777607 (25 mg/kg/day) decreases the number of KHT lung tumor nodules (28.3%), improves the morphological hemorrhage, and significantly impairs the metastatic phenotype in the 6-8 week-old female C3H/HeJ mice injected with rodent fibrosarcoma KHT cells without apparent systemic toxicity compared to the control treatment. A low dose of BMS 777607 (10 mg/kg) also offers a mild but not significant inhibition of lung nodule formation compared to the vehicle control. |
Met Kinase Assay:The kinase reaction consists of baculovirus expressed GST-Met, 3 μg of poly(Glu/Tyr), 0.12 μCi 33P γ-ATP, 1 μM ATP in 30 μL of kinase buffer (20 mM Tris-Cl, 5 mM MnCl2, 0.1 mg/mL BSA, 0.5 mM DTT). Reactions are incubated for 1 hour at 30 °C and stopped by the addition of cold trichloroacetic acid (TCA) to a final concentration of 8%. TCA precipitates are collected onto GF/C unifilter plates using a Filtermate universal harvester, and the filters are quantitated using a TopCount 96-well liquid scintillation counter. Dose response curves are generated to determine the concentration required to inhibit 50% of substrate phosphorylation (IC50). BMS 777607 is dissolved at 10 mM in dimethylsulfoxide (DMSO) and evaluated at 10 concentrations, in duplicate.

* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)
*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).
Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:
Concentration (start) x Volume (start) = Concentration (final) x Volume (final)
This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:
Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
