Comprehensive research information for laboratory professionals
Tirzepatide is a synthetic 39-amino-acid peptide and dual agonist of the glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) receptors. It is the first-in-class "twincretin" and represents a significant advancement in multi-receptor metabolic research . Researchers study tirzepatide for its unique pharmacological profile, which includes biased agonism at the GLP-1 receptor favoring cAMP signaling over β-arrestin recruitment. This signaling bias may optimize metabolic efficacy beyond what is achievable with selective GLP-1R agonists alone.
