Navarixin (MK-7123)(SCH527123) is a novel, selective CXC chemokine receptor 2(CXCR2) antagonist that inhibits neutrophil activation and modulates neutrophil trafficking in animal models, characteristics that may be beneficial in the treatment of conditions with unbalanced pulmonary neutrophilia.

AZD8797 (KAND567) is an orally available, selective and potent human CX3CR1-converting antagonist with inhibitory effects on CX3CR1 and CXCR2, and potentially protects against SARS-CoV-2-induced neuronal damage, preventing worsening of nociceptive sensitization and microglial activation in a migraine model of rats following seizures.

SCH 563705 is an orally available and highly potent CXCR2 and CXCR1 antagonist for the study of acute respiratory syndrome, chronic obstructive pulmonary disease, and inflammation.

CXCR2-IN-2 is a selective CXCR2 antagonist that is brain penetrant and orally bioavailable, with IC50 values of 5.2 nM and 1 nM in the β-arrestin assay and CXCR2 Tango assay, respectively. It exhibits approximately 730-fold selectivity over CXCR1 and greater than 1900-fold selectivity over all other chemokine receptors. Furthermore, CXCR2-IN-2 effectively inhibits Gro-α induced CD11b expression in human whole blood, displaying an IC50 of 0.04 μM[1].
