Retatrutide
Based on 3 publication(s) in Google Scholar
Retatrutide (LY3437943) is a triple agonist peptide of the glucagon receptor (GCGR), glucosedependent insulinotropic polypeptide receptor (GIPR), and glucagon-like peptide-1 receptor (GLP-1R). Retatrutide binds human GCGR, GIPR, and GLP-1R with EC50 values of 5.79, 0.0643 and 0.775 nM, respectively. Retatrutide can be used for the research of obesity.
