PD-135666
CCK B Inhibitor
PD-135666 is a potent dipeptide inhibitor of cholecystokinin B (CCK B) receptors, demonstrating an IC50 of 0.1 nM in mouse cerebral cortex. Unlike its enantiomer, PD-140548, which selectively targets CCK A receptors in rat pancreas, PD-135666 primarily interacts with CCK B receptors. This compound has been shown to exhibit anxiolytic effects in various animal models, making it a valuable tool for studying anxiety-related disorders and CCK receptor biology.
