Abstract

Glucagon-like peptide-1 (GLP-1) receptor agonists as an effective approach for type 2 diabetes mellitus (T2DM) has been explored extensively, multi agonists based on GLP-1 may have better clinical benefits on obesity, Nonalcoholic steatohepatitis (NASH) and other metabolic diseases. To get multi agonists based on GLP-1, 15 conjugates were designed, synthesized, and tested for biological activity. GLP-1/glucagon dual receptor agonist E1 showed moderate long-acting hypoglycemic effect, CY-5 and CY-16 with GLP-1/GIP dual receptor agonistic activity exhibited longer duration of continuous blood glucose stabilization. The long-acting hypoglycemic effect was equal to that of semaglutide. Although they have lost the agonistic activity on Glucagon Receptor, chronic in vivo studies on T2DM mice and diet-induced obesity (DIO) mice showed that CY-5 can effectively reduce food intake, inhibit body weight gain, repair islets damage and improve the glucose tolerance. One month treatment on NASH mice showed that CY-5 can significantly lower the TG, TC, AST, ALT and LDL-C and increase the HDL-C. CY-5 can also improve the liver vacuolation, reduce fat accumulation and delay the process of the fibrosis. The liver protection effect is better than that of semaglutide. In summary, CY-5 is a promising candidate for the treatment of metabolic diseases and worthy for further development.
