A 70874 Usage And Synthesis
Description
A 70874 has high potency and selectivity for cholecystokinin (CCK) A receptors.
Uses
A-70874 is a tyrosine-free tetrapeptide analog of cholecystokinin (30-33) (CCK-4). A-70874 is an agonist that stimulates pancreatic amylase release and a partial agonist that stimulates pancreatic phosphoinositide decomposition. A-70874 has an IC50 of 4.9 nM for the guinea pig pancreatic CCK receptor. Cholecystokinin (CCK) receptors are divided into CCK-A (digestive tract) and CCK-B (brain). A-70874 has an affinity of 1.6 μM for the CCK-B/gastrin receptor[1].
