SB 225002 is a potent and selective CXCR2 chemokine receptor antagonist with IC50 value of 22nM [1].
CXCR2 is a member of the G-protein-coupled receptor family, which is responsible for neutrophil chemotaxis and margination induced by IL-8 [1].
SB 225002 is a potent and selective non-peptide inhibitor of CXCR2. It prevented IL-8 binding to CXCR2 with IC50 value of 22 nM and showed >150-fold selectivity over CXCR1. In HL60 cells, SB 225002 potently prevented IL-8 and GROa-induced neutrophil chemotaxis [1]. In CDDP-resistant and -sensitive OVCA cell lines, SB225002 induced apoptosis in both wild-type and p53-deficient cells in a p53-independent way and promoted mitotic catastrophe [2].
In rabbits, SB 225002 blocked IL-8-induced neutrophil margination [1]. In experimental colitis mice induced by TNBS, SB225002 reduced neutrophil influx, IL-1 , MIP-2, and keratinocyte-derived chemokine (KC) levels, MPO activity and the expression of vascular endothelial growth factor. While, levels of IL-4 and IL-10 were increased significantly in the colons of mice [3].
