Biological Activity

SB225002 inhibits IL-8- (IC50=8nM) and GROα-mediated (IC50=10nM) calcium mobilisation. SB225002 prevents IL-8-induced neutrophil migration. SB225002 inhibits HIV replication in lymphocytes and macrophages. SB 225002 potently inhibited human and rabbit neutrophil chemotaxis induced by both IL-8 and GROalpha.

Protocol
Cell Experiment
Cell lines WHCO1, WHCO5, and WHCO6 cell lines
Preparation method Establishing three esophageal squamous cell carcinoma cell lines WHCO1, WHCO5, and WHCO6 originally from surgical biopsies of primary esophageal squamous cell carcinomas which are cultured in DMEM containing 10% FCS at 37°C in a humidified atmosphere of 5% CO2.Using the Cell Proliferation kit I to carry out MTT assays . Briefly, plating 1.5 × 103 cells in 96-well plates in a final volume of 180 μL DMEM per well.Adding SB 225002 (antagonist of CXCR2, 400 nM)to cells and adding 0.001% DMSO (solvent) as a control. After the indicated incubation period, adding 18 μL of the MTT labeling reagent (final concentration 0.5 mg/mL)to each well and incubating for 4 hours in a humidified atmosphere. Adding one hundred eighty microliters of the solubilization solution to each well and the plates were left overnight at 37°C. Using a microtiter plate reader to measure the spectrophotometric absorbance of samples at 595 nm .

For example, to modify the dose of resveratrol used for a mouse (22.4 mg/kg) to a dose based on the BSA for a rat, multiply 22.4 mg/kg by the Km factor for a mouse and then divide by the Km factor for a rat. This calculation results in a rat equivalent dose for resveratrol of 11.2 mg/kg.

Results To further investigate the role of CXCR2 in epilepsy, we measured the effect of SB225002 on SRSs during the chronic period in the pilocarpine-induced epilepsy mice. The latency period of SRSs was increased (by nearly 40%) in the SB225002 group as compared with the model control and vehicle groups (p < 0.05).
