Abstract

Background: Cholecystokinin receptor type 1 (CCK1R) stimulates satiety. Results: Binding and activity of a CCK1R agonist/CCK2R antagonist are studied at wild-type and chimeric receptors, and ligand-guided model refinement is utilized. Conclusion: The small molecule agonist docking site is distinct from the antagonist site, with benzodiazepines docked with consistent pose, including approximation with Leu7.39. Significance: The molecular model and determinants for small molecule agonist action should facilitate drug development.
