Mechanism of Action

Targets/IC₅₀/Ki	CXCR2 (Cell-free assay) 22 nM
In vitro	In vitro, SB225002 inhibits GROα-stimulated calcium mobilization, and potently inhibits human and rabbit neutrophil chemotaxis induced by both IL-8 and GROalpha. This compound substantially reduces the levels of phosphorylated ERK1/2, and decreases cell proliferation in WHCO1 cells. It also shows the antitumor activity as a microtubule inhibitor.
Kinase Assay	Radioligand Binding Experiments
Kinase Assay	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 vivo	In rabbits, SB225002 selectively blocks IL-8-induced neutrophil margination. In mouse intrahepatic cholangiocellular carcinoma model, this compound (1 mg/kg i.p.) suppresses the growth of transplanted subcutaneous tumors. In addition, it also displays long-lasting antinociceptive effects, and reduces TNBS-induced colitis in mouse models.
