A synthetic, non-peptide CXCR2 antagonist blocks MIP-2-induced neutrophil migration in mice.

Non-peptide antagonists of chemokine receptors are considered an intriguing alternative for the treatment of acute and chronic diseases. Particularly the recruitment of neutrophils to inflammatory sites often causes harmful side effects and is mediated by chemokine ligands of the CXC chemokine receptor 2 (CXCR2). Hence, this receptor has been proposed as an important target for novel drugs.
