AZD-5122 (also known as SRT3109) is a potent and selective CXCR2 (CXC chemokine receptor 2) antagonist under investigation for inflammatory diseases. It exhibits strong affinity for human CXCR2, with an IC₅₀ of approximately 3.4 nM in cell-based calcium flux assays using neutrophils. AZD-5122 demonstrates robust inhibition of CXCL1-induced neutrophil migration (IC₅₀ ~5.1 nM) and blocks downstream signaling such as ERK phosphorylation. In preclinical animal models, AZD-5122 effectively reduced neutrophilic infiltration in inflamed tissues, confirming its anti-inflammatory potential. The compound has entered early-phase clinical trials to assess its pharmacokinetics, safety, and efficacy in diseases like chronic obstructive pulmonary disease (COPD).
