An extensively studied dual GIP/GLP-1 receptor agonist with a novel mechanism engaging two incretin pathways simultaneously. Research has investigated its dual receptor pharmacology and effects on metabolic signaling.
Tirzepatide is a synthetic peptide that activates both the glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) receptors. It is based on the native GIP sequence with modifications to enable GLP-1 receptor cross-reactivity and a C20 fatty diacid moiety for albumin binding and extended half-life. GIP receptor agonism enhances the metabolic signaling effects of GLP-1 pathway activation, including modulation of lipid metabolism and central satiety signaling pathways. The dual mechanism engages complementary metabolic pathways compared to single-receptor agonist approaches.

Key finding: Research investigated the dose-dependent pharmacology of dual GIP/GLP-1 receptor agonism and its effects on metabolic signaling pathways over 72 weeks, comparing dual-receptor engagement to single-agonist approaches.
