GRA Ex-25 is a potent glucagon receptor inhibitor with IC50 of 56nm and 55nM for rat and human glucagon receptors, respectively[1]. GRA Ex-25 binds to the human glucagon receptor (h-GlucRbind) with a Ki of 63nM and moderates glucagon-induced adenylate cyclase inhibition (h-GlucRcyclase) with a Ki of 254nM[2]. GRA Ex-25 (3mg/kg; i.v.; once) reduces blood glucose levels induced by exogenous glucagon in a rat model, possibly due to direct inhibition of glucagon-stimulated hepatic glucose output[2].

| Molecular Docking of the Receptor¨CLigand Complex[1]: | |
|
Preparation Method |
The receptor and small ligand molecules Gra EX-25 were used to conduct molecular docking of 5XEZ-A with dauricine and Gra Ex-25 using Vina computing under the calculation conditions screened. In addition, scoring data and PyMol were used to analyze the ligand and receptor amino acid binding way. |
|
Applications |
Gra Ex-25 is bonded to Ser350 and Lys349 amino acids of GCGR through hydrogen bonding. |
| Animal experiment [2]: | |
|
Animal models |
Glucagon challenged rats |
|
Preparation Method |
Anesthetized animals were given an intravenous dose of GRA Ex-25 min prior to a 3mg/kg glucagon load. |
|
Dosage form |
3mg/kg; i.v.; once |
|
Applications |
GRA Ex-25 (3mg/kg) significantly reduced blood glucose levels in rats with elevated blood glucose induced by exogenous glucagon. |
