PSB-1114 triethylamine

PSB-1114 triethylamine is a potent and enzymatically stable agonist selective for the P2Y2 receptor (EC50 = 134 nM), demonstrating over 50-fold selectivity versus P2Y4 and P2Y6 receptors. This compound is a valuable pharmacological tool for investigating purinergic signaling in vitro and in vivo, particularly in studies of epithelial ion transport, mucociliary clearance, and inflammatory responses.
