gastrin

GRP (porcine) acetate is the gastrin-releasing peptide extracted from porcine pancreata. GRP (porcine) acetate may have a role in the parasympathetic regulation of endocrine and exocrine secretion from the pig pancreas.

Gastrin-Releasing Peptide, human(TFA) is a regulatory human peptide that elicits gastrin release and regulates gastric acid secretion and enteric motor function. The post-ganglionic fibers of the vagus nerve that innervate the G cells of the stomach release GRP, which stimulates the G cells to release gastrin.

Mini Gastrin I, human acetate is a shorter version of human gastrin, consists of amino acids 5-17 of the parent peptide.

Gastrin I, rat is a peptide hormone that effectively stimulates gastric acid secretion.

[Leu15]-Gastrin I, human is a variant of Gastrin I, where the 15th amino acid residue is substituted with leucine (Leu). [Leu15]-Gastrin I (human) regulates the binding of cholecystokinin to the mucosal membrane.

[Leu15]-Gastrin I human acetate(39024-57-2 Free base) is a peptide. It acts through G protein-coupled receptors, known as cholecystokinin (CCK) or CCK-B receptor (CCK-BR).

Gastrin I (1-14), human TFA, is the 1-14 fragment of the human gastrin I peptide.

Gastrin-Releasing Peptide, human is a regulatory human peptide that elicits gastrin release and regulates gastric acid secretion and enteric motor function. The post-ganglionic fibers of the vagus nerve that innervate the G cells of the stomach release GRP, which stimulates the G cells to release gastrin.

Mini Gastrin I, human (TFA) is short for human Gastrin. It is a mother peptide composed of 5-17 amino acids.

Gastrin I (1-14), human, is the 1-14 peptide fragment of human gastrin I, an endogenous gastrointestinal peptide hormone, and is the primary hormonal regulator of gastric acid secretion.

Mini Gastrin I, human, is a truncated form of the human gastrin peptide, encompassing amino acids 5-17 of the original sequence.

Gastrin I, human (Gastrin I (human)) is an endogenous peptide produced in the stomach that increases pepsinogen and acid secretion via the CCK2 receptor in the rat.

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.

Gastrin hexapeptide is a hexapeptide from porcine antral mucosa.

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

Pentagastrin (ICI-50123) is a synthetic polypeptide that mimics the effects of gastrin when administered parenterally, influencing the secretion and synthesis of salivary proteins.

Litorin acetate, an amphibian bombesin peptide derivative, is an bombesin receptor agonist. It stimulates the contraction of smooth muscle, stimulates gastrin, gastric acid, and pancreatic secretion, and suppresses the nutriment in vivo.

Gastrin-releasing peptide (GRP) is a neuropeptide that stimulates gastrin release. It binds to (Ki = 300 nM) and stimulates amylase secretion in rat pancreatic AR42J cells (EC50 = 0.3 nM). GRP increases proliferation of human liver carcinoma HepG2 and MHCC97H cells but does not affect the proliferation of normal HL-7702 liver cells at a concentration of 1 nM. In vivo, GRP (0.35 nmol/kg/h) increases both pancreatic exocrine secretion and pancreatic polypeptide (PP) release in rats. It dose-dependently stimulates gastrin, pancreatic amylase, lipase, bilirubin, and acid output and induces gallbladder contraction in humans when administered at doses ranging from 1 to 27 pmol/kg per hour.

BIM-26226, a gastrin-releasing peptide, serves as a potent and selective antagonist to the bombesin receptor, effectively inhibiting BN- or GRP-stimulated amylase release with IC50 values in the nanomolar range. It is utilized in cancer research [1] [2].

BA 1 TFA acts as a potent agonist for the bombesin (BB) family of receptors, exhibiting high affinity binding to Bombesin receptor subtype-3 (BRS3), gastrin-releasing peptide receptor (GRPR), and neuromedin B receptor (NMBR), with IC50 values of 6, 0.4, and 2.5 nM, respectively [1].

Mazdutide acetate is a potent co-agonist of glucagon-like peptide (GLP-1R) and glucagon receptor (GCGR), a gastrin-regulating hormone analog.Mazdutide acetate stimulates insulin secretion from mouse pancreatic islets, and can be used in studies of obesity and type 2 diabetes (T2D).

PACAP (1-38) free acid TFA, an endogenous neuropeptide, effectively enhances antral motility and somatostatin secretion, while concurrently suppressing gastrin secretion and promoting the release of vasoactive intestinal polypeptide, gastrin-releasing peptide, and substance P. Additionally, it amplifies N-methyl-D-aspartate receptor function and brain-derived neurotrophic factor expression via RACK1 [1] [2].

PACAP (1-38) free acid, an endogenous neuropeptide, potently modulates gastrointestinal and neuroendocrine functions. It enhances antral motility, increases somatostatin secretion, and stimulates the release of vasoactive intestinal polypeptide, gastrin releasing peptide, and substance P, while concurrently inhibiting gastrin secretion. Additionally, it augments N-methyl-D-aspartate receptor function and upregulates brain-derived neurotrophic factor expression via RACK1 [1] [2].

[Lys3]-Bombesin is a biologically active peptide used in PET (Positron Emission Tomography) imaging to identify GRPR (gastrin-releasing peptide receptor) positive prostate cancer. The compound, when conjugated with a corresponding monoclonal antibody, can selectively trigger CD64-dependent monocyte and neutrophil-mediated lysis in small cell carcinoma.
