cholecystokinin

Cholecystokinin, a peptide hormone, functions as a hunger suppressant by inhibiting food intake and promoting the digestion of fat and protein, and is employed in gastrointestinal system research [1] [2] [3].

Cholecystokinin (1-21) (CCK-1-21), a fragment of cholecystokinin (CCK), induces lipolysis in human adipose tissue [1].

Non-sulfated form of the C-terminal octapeptide of CCK

[Thr28, Nle31]-Cholecystokinin (25-33) is a bioactive peptide analog of Cholecystokinin (CCK), functioning as both a hormone and neurotransmitter within the gastrointestinal system and central nervous system, with a role in satiation by inhibiting food intake. Compared to native CCK8, this analog displays enhanced stability in acidic environments and resistance to air oxidation, attributed to the substitution of Methionine with Threonine at position 28 and Norleucine at position 31. Structurally, its predominant feature is a gamma-turn at Thr4, followed by a Gly5-separated helical region encompassing the C-terminal residues.

Cholecystokinin Octapeptide, desulfated TFA, is a synthetic octapeptide derived from Cholecystokinin (CCK) that has undergone desulfation.

V-9-M Cholecystokinin nonapeptide (Prepro CCK Fragment V-9-M) is a precursor compound of cholecystokinin (CCK). Cholecystokinin (CCK) is a brain-intestinal peptide that stimulates gallbladder contraction and pancreatic exocrine. It can be extracted from the small intestine of dogs and cats and can cause gallbladder contraction.

Cholecystokinin (26-33) free acid, a part of cholecystokinin (CCK), is a highly selective ligand for CCKB-type receptors found in the vertebrate CNS and induces a mild taste aversion conditioned reflex in rats.

Cholecystokinin pentapeptide is a peptide hormone of the gastrointestinal system responsible for stimulating the digestion of fat and protein.

Sincalide (CCK-8) is a cholecystokinetic drug administered by injection to aid in diagnosing disorders of the gallbladder and pancreas. It is the 8-amino acid C-terminal fragment of cholecystokinin.

Sincalide ammonium (CCK-8 ammonium) is a potent analog of the amino acid peptide hormone cholecystokinin (CCK), an active fragment that retains much of the biological activity of CCK.Sincalide ammonium promotes bile secretion, causes gallbladder contractions and relaxes the sphincter of Oddi, thereby facilitating bile drainage into the duodenum. Sincalide ammonium promotes bile secretion, contraction of the gallbladder and relaxation of the sphincter of Oddi, thereby facilitating the drainage of bile into the duodenum.Sincalide ammonium can be injected to promote gallbladder contraction, and is commonly used as an adjunct in the diagnosis of gallbladder and pancreatic diseases and in cholecystography.

Tetragastrin is the C-terminal tetrapeptide of gastrin. It has the same physiological and pharmacological activity as gastrin.

Ceruletide (Caerulein) is a potent agonist of cholecystokinin receptor and it also is a safe and effective cholecystokinetic agent. It has a direct spasmogenic effect on the gallbladder muscle and bile ducts.

Gastrin I (human) acetate (Gastrin-17 acetate) is the endogenous peptide produced in the stomach, and increases gastric acid secretion via cholecystokinin 2 (CCK2) receptor.

CCK Octapeptide, non-sulfated acetate is a synthetic desulfated peptide of cholecystokinin.

Ceruletide Ammonium Salt is a decapeptide, originating from the skin of tropical frogs, which is a potent cholecystokinin receptor agonist and a safe and effective cholecystokinin receptor agonist with direct spasmodic effects on the gallbladder muscle and bile ducts. Ceruletide Ammonium Salt has sedative activity and has been used in the study of chronic schizophrenia.Ceruletide Ammonium Salt is a decapeptide, originating from the skin of tropical frogs.

Ceruletide Ammonium acetate (FI-6934 Ammonium acetate) is a cholecystokinin (CCK) receptor agonist. Ceruletide Ammonium acetate is a safe and effective cholecystokinetic agent and small bowel and exocrine pancreatic stimulant.

[Leu15]-Gastrin I human (Amino Acid Sequence Glp-Gly-Pro-Trp-Leu-Glu-Glu-Glu-Glu-Glu-Ala-Tyr-Gly-Trp-Leu-Asp-Phe-NH2) encodes for the protein [Leu15]-Gastrin I in human. In human chromosome, the gene GAST is localized on 17q21.2. G cells in the stomach antrum produces the precursor of [Leu15]-Gastrin I, progastrin.Progastrin undergoes cleavage and processing to yield gastrin, which is trophic for the entire gastrointestinal epithelium. Gastrin is essential for the growth of the digestive system and stimulates the production of gastric acid by parietal cells. Gastrin exerts its function through G-protein-coupled receptor called the cholecystokinin (CCK) or CCK-B receptor (CCK-BR). Gastrin release is stimulated by food, especially protein diet and is inhibited by very low pH. Atrophic gastritis, a Helicobacter pylori infection and long-term administration of proton pump inhibitors infection may cause overexpression of gastrin. Gastric adenocarcinoma show high levels of gastrin.

Pentagastrin (ICI-50123) is a synthetic polypeptide that has effects like gastrin when given parenterally, which can cause the secretion and synthesis of salivary proteins.
