Abstract

Liraglutide and semaglutide, both approved for long-term weight management, significantly reduce food intake and delay gastric emptying.

  • Unimolecular polypharmacology represents an advance in obesity treatment by using single molecules to target multiple pathways.
  • Tirzepatide, a dual agonist, activates both GLP-1 and GIP receptors, showing enhanced weight loss potency compared to traditional GLP-1 mono agonists.
  • Preliminary data indicate that GLP-1/glucagon dual agonists and GLP-1/GIP/glucagon triple agonists may provide better weight loss results than GLP-1 mono agonists.
  • Understanding the mechanisms of these unimolecular multitargeting agents could inform future clinical applications and drug development for obesity.
