Novel GLP-1(28-36) amide-derived hybrid peptide A3 with weight loss and hypoglycemic activities

Eur J Pharmacol. 2023 Dec 15:961:176200. doi: 10.1016/j.ejphar.2023.176200. Epub 2023 Nov 16.

Abstract

Glucagon-like peptide-1 (GLP-1) has gained much attention in the last decade for the treatment of type 2 diabetes. Accumulating evidence indicates that some metabolites of GLP-1 have biological activities that might contribute to the pleiotropic effects of GLP-1 independent of the GLP-1 receptor. The hypoglycemic and weight-reducing effects of the reported metabolites and modifications still need to be confirmed. In this study, we started from the C-terminal nonapeptide GLP-1(28-36) amide and developed a series of GLP-1(28-36) amide-derived hybrid peptides. Our findings of biological activity evaluation in INS-1 cells, streptozotocin-induced diabetic and diet-induced obesity mice confirmed a novel hybrid peptide, A3, and provided a new perspective in the development of new drugs from peptide metabolites.

Keywords: Glucagon-like peptide-1; Metabolite; Obesity; Type 2 diabetes.
