Description

Desaminopancreozymin Octapeptide is a synthetic bioactive peptide analog of the C-terminal octapeptide of cholecystokinin (CCK-8). This compound is a valuable research tool for studying gastrointestinal and central nervous system functions, particularly as a potent CCK receptor agonist. It is primarily utilized by pharmaceutical researchers, academic institutions, and biotechnology companies engaged in metabolic, neurological, and digestive system research and development.

Application

• Pharmacological Research: Used as a standard agonist in studies investigating the physiological roles of cholecystokinin (CCK) receptors.
• Gastrointestinal Studies: Applied in in vitro and in vivo models to stimulate pancreatic enzyme secretion and gallbladder contraction.
• Neuroscience Research: Employed to explore the effects of CCK on satiety, anxiety, pain modulation, and dopamine release in the brain.
• Drug Discovery: Serves as a reference compound for screening and developing new therapeutic agents targeting CCK receptors for conditions like obesity, pancreatitis, and anxiety disorders.
• Biochemical Assay Development: Used in the development and validation of receptor binding assays and functional cellular assays.
• Academic & Clinical Research: Provides a critical tool for basic science investigations into hormone action and peptide signaling pathways.
