      Description
      OverviewA cyclohexenone based compound that selectively inhibits CXCR2-mediated recruitment of β-arrestin-2 (IC50 = 6.3 µM) and receptor internalization in U2OS cells, but does not affectCXCL-8 mediated turnover of CXCR2. Believed to interact with the C-terminal region of CXCR2 in close proximity to the receptor phosphorylation sites. Its action appears to be non-competitive and allosteric in nature. Does not affect the activity of CXCR4 (IC50 >100 µM). Shown to transiently increase CXCL8 -induced ERK1/2 phosphorylation. Does not affect CXCL8-mediated cAMP signaling in 293T-CXCR2-GFP-p22F cells. Inhibits CXCL8-mediated cell migration in a wound healing assay and reduces polymorphonuclear leukocyte migration in a lipopolysaccharide-induced inflammation model.

      Please note that the molecular weight for this compound is batch-specific due to variable water content.

      DescriptionA cyclohexenone based compound that selectively inhibits CXCR2-mediated recruitment of ?-arrestin-2 (IC50 = 6.3 µM) and receptor internalization in U2OS cells, but does not affectCXCL-8 mediated turnover of CXCR2.
