Technical Advantages and Disadvantages of Glucagon Products

The functions of glucagon offer clear advantages in receptor specificity, with a binding affinity (Kd) of 0.5 nM for the GCGR, minimizing off-target effects. However, technical disadvantages include rapid enzymatic degradation by dipeptidyl peptidase-4 (DPP-4) and neutral endopeptidase (NEP), reducing half-life to 3-6 minutes in circulation. To overcome this, the functions of glucagon are enhanced through PEGylation or fatty acid conjugation, extending half-life to 12-24 hours in modified analogs. For example, a glucagon analog with a C-terminal palmitic acid chain shows a 10-fold increase in plasma stability. The functions of glucagon in native form also require cold-chain logistics (2-8°C), which increases supply chain costs by 20-30%. In contrast, lyophilized products reduce this burden, with a 15% lower logistics cost compared to liquid formulations. The functions of glucagon in dual-agonists also face challenges in balancing receptor activation ratios, with optimal GCGR/GLP-1R activity ratios of 1:1 to 1:3 for metabolic benefits.
