At present, type 2 diabetes and its abnormal metabolism-related indicators are mainly treated using hypoglycemic, hypotensive, lipid-lowering, and insulin-sensitizing drugs, such as Metformin [5], glucagon-likepeptide-1(GLP-1) analogs [6], and sodium-glucose cotransporter-2 (SGLT-2) inhibitors [7], together with diet modification and exercise. Here, GCG is linked to type 2 diabetes mellitus.
