| | SB 225002 Usage And Synthesis |
| Description | CXCR2 (IL-8RB) is a seven-transmembrane G protein-coupled receptor whose physiological ligands include IL-8 (CXCL8) and growth related oncogene α (Gro-α; CXCL1). IL-8 and Gro-α are pro-inflammatory CXC chemokines that act as chemoattractants, especially for neutrophils, and promote angiogenesis. SB 225002 is a selective non-peptide inhibitor of CXCR2, inhibiting IL-8 binding to CXCR2 with an IC50 value of 22 nM. SB225002 inhibits neutrophil chemotaxis in response to IL-8 in vitro (IC50 = 20 nM) and blocks neutrophil margination induced by IL-8 in vivo (IC50 = 30 nM). Similarly, SB 225002 reduces neutrophil influx, the production of inflammatory mediators, and tissue damage in TNBS-induced colitis in mice. | | Uses | SB 225002 is a potent and selective CXCR2 antagonist with the ability to inhibit interleukin IL-8 binding to CXCR2. | | Definition | ChEBI: 1-(2-bromophenyl)-3-(2-hydroxy-4-nitrophenyl)urea is a nitrophenol. | | Biological Activity | Potent and selective CXCR2 chemokine receptor antagonist (IC 50 = 22 nM) that displays > 150-fold selectivity over CXCR1 receptors. Causes inhibition of IL-8 and GRO α -mediated calcium mobilization in HL60 cells (IC 50 values are 8 and 10 nM respectively). Prevents IL-8-induced neutrophil chemotaxis in vitro and sequestration in vivo . Inhibits HIV replication in lymphocytes and macrophages. | | Biochem/physiol Actions | SB-225002 is a potent nonpeptide inhibitor of chemokine receptor CXCR2 with an IC50 of 22 nM for inhibiting interleukin IL-8 binding to CXCR2 and > 150-fold selectivity over CXCR1 receptors. CXCR2 binds many different immune cell chemoattractants. SB-225002 is crucial for cancer progression and is involved in inflammatory diseases like COPD, rheumatoid arthritis, and ulcerative colitis. | | storage | Store at RT | | References | 1) White et al.
