Description

Pentagastrin is a synthetic polypeptide that has effects like gastrin when given parenterally. It stimulates the secretion of gastric acid, pepsin, and intrinsic factor, and has been used as a diagnostic aid as the pentagastrin-stimulated calcitonin test. Pentagastrin binds to the cholecystokinin-B receptor, which is expressed widely in the brain. Activation of these receptors activates the phospholipase C second messenger system. (In Vitro) :Pentagastrin (ICI-50123) (0.1-100 μM; GH3-cells) increases intracellular Ca2+ in a dose-dependent manner with a maximal increase of 2.77-fold.Pentagastrin (ICI-50123) (0.1-100 μM; GH3-cells) bounds dose dependently to GH3 cells. (In Vivo) :Pentagastrin (ICI-50123) (80 μg/kg/h; i.v.; male Sprague-Dawley rats) protects rat gastric mucosa from acidified aspirin injury.
