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 3 ¦̧/kg glucagon load. |
|
Dosage form |
1-3mg/ml GRA Ex-25 |
|
Applications |
GRA Ex-25 (3 mg/kg) significantly reduced blood glucose levels in rats with elevated blood glucose induced by exogenous glucagon. |

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.
Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
