Retatrutide

Also known as LY3437943
39-residue triple agonist with a gGlu-C20 lipid modification

A synthetic triple agonist of the GLP-1, GIP, and glucagon receptors, studied as the next step beyond dual incretin agonists.

Retatrutide (LY3437943) is engineered to activate all three incretin/glucagon-axis receptors (GLP-1R, GIPR, GCGR). A C20 fatty-diacid attachment confers albumin binding and an extended functional half-life, and the combined receptor activity produces a distinct downstream signaling profile relative to dual or mono-agonists. It is widely used as a reference standard in comparative metabolic-receptor research.

Common research areas

  • Triple-receptor activation studies
  • Comparative cAMP/beta-arrestin assays vs tirzepatide & semaglutide
  • In-vitro metabolic phenotype models
