SB225002

SKU: orb1306985

Description

SB225002 is a selective small molecule antagonist of the CXCR2 chemokine receptor, effectively blocking IL-8 binding. It is widely used in research to investigate CXCR2's role in neutrophil migration, inflammation, and cancer biology in both cellular and animal models.

Bioactivity

• Target IC50:
  CXCR2:22 nM
• In Vivo:
  SB225002 demonstrates antitumor activity as a microtubule inhibitor. It significantly reduces the levels of phosphorylated ERK1/2 and decreases the proliferation of WHCO1 cells. In vitro, SB225002 inhibits calcium mobilization stimulated by GROα and effectively suppresses the chemotaxis of human and rabbit neutrophils induced by IL-8 and GROα.

• In Vitro:
  SB225002 demonstrates prolonged analgesic effects and reduces TNBS-induced colitis in mouse models. In rabbits, SB225002 selectively inhibits the margination of neutrophils induced by IL-8. Moreover, at a dosage of 1 mg/kg i.p., SB225002 suppresses the growth of subcutaneously transplanted tumors in a mouse model of intrahepatic cholangiocarcinoma.

• Cell Research:
  Three esophageal squamous cell carcinoma cell lines WHCO1, WHCO5, and WHCO6 originally established from surgical biopsies of primary esophageal squamous cell carcinomas are cultured in DMEM containing 10% FCS at 37°C in a humidified atmosphere of 5% CO2. MTT assays are carried out using the Cell Proliferation kit I. Briefly, 1.5 × 103 cells are plated in 96-well plates in a final volume of 180 μL DMEM per well. SB 225002 (antagonist of CXCR2, 400 nM) is added to cells and 0.001% DMSO (solvent) is added as a control. After the indicated incubation period, 18 μL of the MTT labeling reagent (final concentration 0.5 mg/mL) is added to each well and incubated for 4 hours in a humidified atmosphere. One hundred eighty microliters of the solubilization solution are added to each well and the plates were left overnight at 37°C. The spectrophotometric absorbance of samples is measured at 595 nm using a microtiter plate reader.(Only for Reference)
