The inhibitor SB225002 significantly decreased J82-, CXCL2- or MIF-mediated MDSC migration. The bars represent the s.e.m. of three experiments. *P<0.05.

(e, f) Administration of the selective CXCR2 antagonist SB225002 mitigated mechanical hyperalgesia and heat hyperalgesia in CCI rats. Antinociceptive effects of a single intrathecal (it.) injection of 20 µg SB225002 were observed at 1 h and disappeared at 2 h. Antinociceptive effects induced by a single injection of SB225002 at 40 µg were observed at 1 h and disappeared 6 h after injection. Injection of SB225002 (10 µg, i.t.) did not alter the PWT and PWL of CCI rats. N = 6 rats for each group, *p < .05, compared to NS group. PWL: paw withdraw latency; PWT: paw mechanical withdrawal thresholds.

|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.
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.
