Description
Sincalide, also known as Cholecystokinin octapeptide (CCK-8), is a synthetic peptide analogue of the natural gastrointestinal hormone cholecystokinin. It mimics the biological effects of endogenous CCK by binding to the same receptors, primarily CCK-A receptors.
Sincalide stimulates gallbladder contraction, pancreatic enzyme secretion, and bile flow, making it valuable in gastrointestinal motility and digestive function studies. It promotes bile drainage into the duodenum by increasing bile secretion, contracting the gallbladder, and relaxing the sphincter of Oddi. This compound is often used in postevacuation cholecystography research and in studies of pancreatic and biliary physiology.
Sincalide is manufactured in a GMP-compliant facility to ensure high quality, consistency, and 99.01% purity.
For laboratory research use only. Not for human or veterinary use.

Mechanism of Action & Research Applications
Sincalide mimics the action of cholecystokinin (CCK) by binding to CCK receptors, primarily the CCK-A subtype found in the gallbladder and pancreas. Through receptor-mediated activity, Sincalide promotes the release of digestive enzymes from the pancreas, triggers gallbladder contraction, and relaxes the sphincter of Oddi, facilitating bile flow into the duodenum.
Research Applications:
Gallbladder contractility studies
Postevacuation cholecystography
Bile secretion and digestive hormone studies
Pancreatic enzyme secretion research
Gastrointestinal motility studies
Hormonal receptor binding research

Precautions
In laboratory environments, Sincalide may:
Induce transient gastrointestinal cramping in animal models
Alter bile acid composition and flow rate
Modulate pancreatic enzyme secretion
These observations are limited to preclinical models and are not applicable to humans or clinical settings.
