CCKBR agonist-1 | 98.48% | CCKBR agonist-1 (Compound 3r1) is a Gq-protein-preferring cholecystokinin B receptor (CCKBR) agonist with an EC50 of 35 pM. CCKBR agonist-1 significantly increases the survival rate of neurons, with an EC50 of 37 pM. CCKBR agonist-1 can improve the cognitive decline in mice by upregulating α-secretase (ADAM10) and calcium signaling molecule PLCB4, reduce the number of amyloid β (Aβ) plaques, and promote long-term potentiation (LTP). CCKBR agonist-1 can be used for the study of Alzheimer's disease. | ||||||||||||||||||||

A-57696 | A-57696 is a cholecystokinin antagonist with selective activity at cortical CCK-B receptors (IC50 = 25 nM). A-57696 behaves as a competitive antagonist in reversing CCK8-stimulated pancreatic alpha-amylase secretion and phosphatidylinositol degradation. A-57696 fails to induce gallbladder contraction and inhibits CCK8-induced contraction. A-57696 behaves as a partial agonist at CCK-B/gastrin receptors on NCI-H345 cells, achieving 80% of the maximal CCK8 response. A-57696 and CCK8 inhibit each other in a calcium mobilization assay. | |||||||||||||||||||||
