The chemokine receptor CXCR2 is expressed on various immune cells and is essential for neutrophil recruitment and angiogenesis at sites of acute and chronic inflammation caused by tissue injury or infection. CXCR2 and its ligand, CXCL8, are implicated in a number of inflammation-mediated diseases such as chronic obstructive pulmonary disease, cystic fibrosis, and cancer. Though the development of CXCR2-specific small-molecule inhibitors as anti-inflammatory agents has been pursued by pharmaceutical companies within the past decade, there are currently no clinically approved CXCR2 inhibitors.

Several CXCR2 antagonists have been described and the blockade of CXCR2 has shown promise in pre-clinical disease models and early clinical trials. However, given its potential, there are fewer distinct classes of antagonists of CXCR2 than of other clinically relevant molecular targets.
