Description: Potent and selective CXCR2 antagonist
Chemical Name: N-(2-Bromophenyl)-N'-(2-hydroxy-4-nitrophenyl)urea
Purity: ≥99% (HPLC)
Biological Activity for SB 225002
SB 225002 is a potent and selective CXCR2 chemokine receptor antagonist (IC50 = 22 nM) that displays > 150-fold selectivity over CXCR1 receptors. Causes inhibition of IL-8 and GROα-mediated calcium mobilization in HL60 cells (IC50 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.

Rheumatoid Arthritis Poster
Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
