Glucagon receptor antagonists block the receptor through which glucagon raises hepatic glucose output. The glucagon receptor (GCGR) is a class B G protein-coupled receptor (GPCR) expressed mainly in liver and kidney. Expression cloning of the rat receptor in 1993 described its signaling through cyclic adenosine monophosphate (cAMP) and intracellular calcium. Small-molecule antagonists in this list include MK 0893, adomeglivant and PF-06291874, which serve as tools in models of glucose homeostasis and type 2 diabetes. Glucagon (Human, Porcine) is included as the native peptide agonist for receptor activation assays. The set also contains related incretin tools for glucagon-like peptide 1 (GLP-1) research, such as Glucagon-Like Peptide 1 (7-36) Amide and GLP-1R Antagonist 1.

Glucagon receptor antagonist-7 is a potent inhibitor of the human glucagon receptor (hGCGR), demonstrating an IC50 of 181 nM for blocking the binding of 125I-labeled glucagon. With a KDB of 81 nM, it inhibits glucagon-stimulated adenylyl cyclase activity in CHO cells. This compound effectively reduces glucagon-mediated glycogenolysis in human hepatocytes and has been shown to lower blood glucose levels, making it a valuable tool for research in glucose metabolism and diabetes therapeutic strategies.
