Retatrutide (LY3437943) acetate is a triple agonist peptide designed for research use, targeting the glucagon receptor (GCGR), glucose-dependent insulinotropic polypeptide receptor (GIPR), and glucagon-like peptide-1 receptor (GLP-1R). It exhibits high inhibitory activity with EC50 values of 5.79 nM for human GCGR, 0.0643 nM for human GIPR, and 0.775 nM for human GLP-1R. In mouse models, the EC50 values are 2.32 nM for GCGR, 0.191 nM for GIPR, and 0.794 nM for GLP-1R.
In vivo studies demonstrate that Retatrutide acetate engages with GCGR to enhance glucose tolerance through GIP or GLP-1 receptor pathways. Activation via the glucagon receptor results in significant weight reduction and increased energy expenditure, making it a valuable compound for obesity research.
