IC50 of Pazopanib that block ANDV-induced EC permeability. Endothelial cells were ANDV infected, and 3 days postinfection the permeability of cells in response to VEGF addition was determined in the presence or absence of increasing amounts of kinase inhibitor. (B): VEGFR2-Src inhibitors block ANDV-induced permeability. Endothelial cells were plated on vitronectin-coated Transwell inserts and infected at an MOI of 0.5 in triplicate with ANDV. Three days postinfection, the permeability of ANDV- and mock-infected endothelial cell monolayers was determined at indicated times in the presence or absence of Pazopanib.

Effect of HDIL-2/TKI on apoptosis of RCC cells. Three RCC cell lines treated with different concentrations of Pazopanib and HDIL-2 and incubated for 48 h. Microscopic images show apoptotic materials 48 h following treatment (arrows show the apoptotic materials in the pazopanib-treated cells).

MRC5 non-transformed human lung fibroblasts were infected with influenza viruses (100 multiplicity of infection). Two hours after infection the cells were treated with vehicle control; sorafenib tosylate (2mM); pazopanib (2mM); OSU-03012 (2mM); and AR-13 (2mM). Twenty-four hours after infection the cells are treated with live/dead agent where green cells are viable and cells staining yellow or red are considered dead. Cells are examined at 10 magnification in a Hermes wide-field microscope (n¼3 SEM) P<0.05 less than vehicle control level of virus-mediated cell killing.

|Description||Pazopanib HCl (GW786034 HCl) is a novel multi-target inhibitor of VEGFR1, VEGFR2, VEGFR3, PDGFR, FGFR, c-Kit and c-Fms with IC50 of 10 nM, 30 nM, 47 nM, 84 nM, 74 nM, 140 nM and 146 nM in cell-free assays, respectively.|
|Features||A multi-kinase inhibitor.|
Pazopanib potently inhibits VEGF-induced phosphorylation of VEGFR2 in HUVEC cells with IC50 of 8 nM.  Pazopanib shows dose-dependent growth inhibition in all synovial sarcoma cell lines including SYO-1 and HS-SY-II cells. Proliferation of SYO-1 and HS-SY-II cells is inhibited even at 1 µg/mL of Pazopanib and is completely abolished at 5 µg/mL. Pazopanib induces G1 arrest, and thereby suppresses the growth of synovial sarcoma cells. Phosphorylation of Akts, GSK-3β, JNKs, p70 S6 Kinase, and mTOR is suppressed in Pazopanib-treated SYO-1 cells compared with that in the vehicle-treated cells.  Pazopanib between 20 m g/mL and 22.5 m g/mL shows an increasing reduction of RPE cell viability. 
|In vivo||The mice treated with 30 mg/kg or 100 mg/kg Pazopanib reveals a significant decrease in tumor burden compared with the mice treated with vehicle or 10 mg/kg Pazopanib. Treatment with Pazopanib is well-tolerated and there is no significant difference in the body weight among the mice in each group. |
Kinase enzyme assays:VEGFR enzyme assays for VEGGR1, VEGFR2, and VEGFR3 are run in homogeneous time-resolved fluorescence (HTRF) format in 384-well microtiter plates using a purified, baculovirus-expressed glutathione-S-transferase (GST) fusion protein encoding the catalytic c-terminus of human VEGFR receptor kinases 1, 2, or 3. Reactions are initiated by the addition of 10 μL of activated VEGFR2 kinase solution [final concentration, 1 nM enzyme in 0.1 M HEPES, pH 7.5, containing 0.1 mg/mL bovine serum albumin (BSA), 300 μM dithiothreitol (DTT)] to 10 μL substrate solution [final concentration, 360 nM peptide, (biotin-aminohexyl-EEEEYFELVAKKKK-NH2), 75 μM ATP, 10 μM MgCl2], and 1 μL of titrated Pazopanib in DMSO. Plates are incubated at room temperature for 60 min, and then the reaction is quenched by the addition of 20 μL of 100 mM ethylene diamine tetraacetic acid (EDTA). After quenching, 20 μL HTRF reagents (final concentration, 15 nM Streptavidin-linked allophycocyanin, 1 nM Europium-labeled antiphosphotyrosine antibody diluted in 0.1 mg/mL BSA, 0.1 M HEPES, pH 7.5) is added and the plates incubated for a minimum of 10 min. The fluorescence at 665 nM is measured with a Wallac Victor plate reader using a time delay of 50 μs.

For best results, use promptly after mixing.
* 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 (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.
