CCK

Cholecystokinin receptors (CCKRs) are a class of G-protein coupled receptors that respond to the peptide hormone cholecystokinin (CCK). CCK is predominantly found in the gastrointestinal tract and the central nervous system. There are two primary subtypes of cholecystokinin receptors: CCK-A (CCK1) receptor, mainly located in the pancreas, gallbladder, stomach, and certain areas of the brain, and CCK-B (CCK2) receptor, found predominantly in the brain and the stomach lining.

The primary function of CCKRs is to mediate the physiological actions of CCK. In the digestive system, CCK is involved in stimulating the digestion of fats and protein. It achieves this by inducing the secretion of digestive enzymes from the pancreas and bile from the gallbladder. Moreover, CCK plays a crucial role in regulating appetite by promoting satiety, making it a point of interest in obesity research.

In the central nervous system, CCK is involved in various functions, including anxiety, pain, and neuroendocrine control. CCK and its receptors are also implicated in psychiatric disorders like anxiety and panic attacks.

CCKRs are also significant in the medical field as potential targets for therapeutic intervention. For instance, CCK-B antagonists are being explored for their potential in treating anxiety disorders and gastrointestinal issues.

Overall, cholecystokinin receptors are integral to various physiological processes, from digestion to brain function, highlighting their importance in both understanding bodily functions and developing medical treatments.

    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.
