|Description||SB225002 is a potent, and selective CXCR2 antagonist with IC50 of 22 nM for inhibiting interleukin IL-8 binding to CXCR2, > 150-fold selectivity over the other 7-TMRs tested.|
In vitro, SB225002 inhibits GROα-stimulated calcium mobilization, and potently inhibits human and rabbit neutrophil chemotaxis induced by both IL-8 and GROalpha.  SB 225002 substantially reduces the levels of phosphorylated ERK1/2, and decreases cell proliferation in WHCO1 cells.  SB225002 also shows the antitumor activity as a microtubule inhibitor. 
|In vivo||In rabbits, SB225002 selectively blocks IL-8-induced neutrophil margination.  In mouse intrahepatic cholangiocellular carcinoma model, SB225002 (1 mg/kg i.p.) suppresses the growth of transplanted subcutaneous tumors.  In addition, SB225002 also displays long-lasting antinociceptive effects, and reduces TNBS-induced colitis in mouse models.  |
Radioligand Binding Experiments:Assays are performed in 96-well microtiter plates where the reaction mixture contains 1.0 μg/ml membrane protein in 20 mM Bis-Tris-propane, pH 8.0, with 1.2 mM MgSO4, 0.1 mM EDTA, 25 mM NaCl, and 0.03% CHAPS and SB 225002 (10 mM stock in Me2SO) added at the indicated concentrations, the final Me2SO concentration is <1% under standard binding conditions. Binding is initiated by addition of 0.25 nM 125I-IL-8 (2,200 Ci/mmol). After 1-h incubation at room temperature the plate is harvested using a Tomtec 96-well harvester onto a glass fiber filtermat blocked with 1% polyethyleneimine, 0.5% BSA and washed three times with 25 mM NaCl, 10 mM Tris·HCl, 1 mM MgSO4, 0.5 mM EDTA, 0.03% CHAPS, pH 7.4. The filter is dried, sealed in a sample bag containing 10 ml of Wallac 205 Betaplate liquid scintillation fluid, and counted with a Wallac 1205 Betaplate liquid scintillation counter.

|In vitro||DMSO||70 mg/mL (198.78 mM)|
|Ethanol||3 mg/mL warmed (8.51 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
2% DMSO+30% PEG 300+5% Tween 80+ddH2O
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.

1.Please make sure the liquid is clear before adding the next solvent.
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.
