2 Customer Reviews
Four FGFR inhibitors, namely PD-173074 (PD-74), PD-166866 (PD-66), SU5402 (SU54) and NVP-BGJ398 (BG-98), inhibit A673, SKNMC, POE, RDES and SKES Ewing cell growth in vitro in a dose-dependent manner, whereas normal cells (IMR90 fibroblasts) remained unaffected. PD-74 proved to be most effective in four out of five Ewing sarcoma cell lines tested. Cells were grown in 10% FBS conditions and cell proliferation was measured after 72 h using a Resazurin assay.

HUVEC spheroids embedded in fibrin gel were incubated with a pool of PDR vitreous fluid samples (1:4 dilution) in the absence or in the presence of different extracellular (a) pathway inhibitors. Formation of radially growing sprouts was evaluated after 24 h of incubation. Data are the mean ± S.E.M. of 30 spheroids per experimental point. *p<0.05, **p<0.01 versus PDR vitreous.

|Description||SU5402 is a potent multi-targeted receptor tyrosine kinase inhibitor with IC50 of 20 nM, 30 nM, and 510 nM for VEGFR2, FGFR1, and PDGF-Rβ, respectively.|
SU5402 inhibits VEGF-, FGF-, PDGF- dependent cell proliferation with IC50 of 0.05 μM, 2.80μM, 28.4 μM, respectively.  In HUVECs, SU5416 selectively inhibits VEGF-driven mitogenesis in a dose-dependent manner with IC50 of 0.04 μM.  In nasopharyngeal epithelial cells, SU5402 attenuates LMP1-mediated aerobic glycolysis, cellular transformation, cell migration, and invasion.  In mouse C3H10T1/2 cells, SU 5402 diminishes the effect of FGF23 on cell differentiation. 
|In vivo||In mice, SU5416 (25 mg/kg, i.p.) inhibits subcutaneous growth of a panel of tumor cell lines by inhibiting the angiogenic process associated with tumor growth. |
FGF-R1 and Flk-1/KDR kinase assays.:The catalytic portion of FGF-R1 and Flk-1/KDR are expressed as GST fusion proteins following infection of Spodoptera frugiperda (sf9) cells with engineered baculoviruses. GST-FGFR1 and GST-Flk1 are purified to homogeneity from infected sf9 cell lysates by glutathione sepharose chromatography. The assays are performed in 96-well microtiter plates that had been coated overnight with 2.0 μg of a polyGlu-Tyr peptide (4:1) in 0.1 mL of PBS per well. The purified kinases are diluted in kinase assay buffer (100 mM Hepes pH 7.5, 100 mM NaCl, and 0.1 mM sodium orthovanadate) and added to all test wells at 5 ng of GST fusion protein per 0.05 mL volume buffer. Test compounds are diluted in 4% DMSO and added to test wells (0.025 mL/well). The kinase reaction is initiated by the addition of 0.025 mL of 40 μM ATP/40 mM MnCl2, and plates are shaken for 10 min before stopping the reactions with the addition of 0.025 mL of 0.5 M EDTA. The final ATP concentration was 10 μM, which is twice the experimentally determined Km value for ATP. Negative control wells receive MnCl2 alone without ATP. The plates are washed three times with 10 mM Tris pH 7.4, 150 mM NaCl, and 0.05% Tween-20 (TBST). Rabbit polyclonal anti-phosphotyrosine antiserum is added to the wells at a 1:10000 dilution in TBST for 1 h. The plates are then washed three times with TBST. Goat anti-rabbit antiserum conjugated with horseradish peroxidase was then added to all wells for 1 h. The plates are washed three times with TBST, and the peroxidase reaction is detected with the addition of 2,2‘-azinobis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS). The color readout of the assay is allowed to develop for 20−30 min and read on a Dynatech MR5000 ELISA plate reader using a 410 nM test filter.

2.Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × 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.
