CP-289,503 is an inhibitor of the complement C5a receptor, with an IC₅₀ of 1 μM. The C5a receptor mediates pro-inflammatory signaling by binding to C5a, a complement activation product that stimulates leukocyte and phagocyte activation, upregulates integrins, and induces degranulation of inflammatory cells, contributing to endothelial damage. By blocking C5a signaling, CP-289,503 may be useful in the treatment of various inflammatory diseases.
