Glucagon-like peptide-1 (GLP-1) is an incretin hormone primarily secreted by intestinal L-cells in response to nutrient intake. Discovered in the 1980s, it plays a critical role in glucose homeostasis by stimulating insulin secretion, inhibiting glucagon release, slowing gastric emptying, and promoting satiety. However, native GLP-1 has a very short half-life (<2 minutes) due to rapid degradation by dipeptidyl peptidase-4 (DPP-4) and renal clearance, limiting its therapeutic potential.
This limitation drove the development of GLP-1 receptor agonists (GLP-1 RAs) through recombinant protein engineering. Early innovations included exenatide, derived from the exendin-4 peptide found in Gila monster saliva, which shares 53% homology with human GLP-1 but resists DPP-4 degradation. Subsequent generations focused on structural modifications to enhance stability and prolong action. Liraglutide, introduced in 2010. incorporated a fatty acid side chain for albumin binding, extending its half-life to 13 hours. Semaglutide, approved in 2017. achieved once-weekly dosing through additional structural optimization and albumin conjugation.
These recombinant analogs not only improve glycemic control in type 2 diabetes but also demonstrate cardiovascular benefits and significant weight-loss effects via central nervous system pathways. Their success has expanded research into dual/triple agonists targeting GLP-1. GIP, and glucagon receptors for enhanced metabolic outcomes. Recent advancements in delivery systems, including oral formulations and sustained-release technologies, further address patient compliance challenges. Beyond diabetes and obesity, ongoing studies explore potential applications in non-alcoholic steatohepatitis (NASH), neurodegenerative diseases, and cardiorenal protection, positioning GLP-1-based therapies as transformative agents in metabolic medicine.
