Cholecystokinin-33 (10-20) (bovine, porcine) CAS NO.100900-23-0

Cholecystokinin-33 (10-20) (bovine, porcine) is an 11-amino acid bioactive fragment derived from the central region of the full-length cholecystokinin-33 (CCK-33) peptide. This synthetic peptide retains key receptor-binding motifs and is widely utilized in gastrointestinal and neurological research to study CCK receptor signaling without the complexity of the full-length hormone. It serves as a critical tool for investigating appetite regulation, pancreatic secretion, and anxiety-related behaviors in preclinical models.

1.MECHANISM OF ACTION

The peptide functions as an agonist for both CCK1 (peripheral) and CCK2 (central) receptors, though with potentially modified affinity compared to shorter sulfated forms. Upon binding, it activates Gq protein-coupled signaling pathways, leading to phospholipase C activation, intracellular calcium mobilization, and downstream kinase cascades. This results in the stimulation of gallbladder contraction, pancreatic enzyme secretion, and modulation of dopamine and serotonin neurotransmission in the brain, influencing satiety and emotional responses.

3.CLINICAL EFFICACY OF PRODUCT

In experimental models, Cholecystokinin-33 (10-20) demonstrates efficacy in reducing food intake and stimulating pancreaticobiliary secretions, validating its role in mimicking physiological CCK actions. Studies show it can induce satiety and alter exploratory behavior in rodents, supporting its use as a reliable reagent for elucidating CCK-mediated pathways. While not used directly in human therapy, its consistent bioactivity makes it a valuable standard for translational research.
