ECHEMI Editorial Reference

Retatrutide is a novel triple agonist peptide of the glucagon receptor (GCGR), glucose-dependent insulinotropic polypeptide receptor (GIPR) and glucagon-like peptide-1 receptor (GLP-1R). Retatrutide inhibits human GCGR, GIPR and GLP-1R with EC50 values of 5.79, 0.0643 and 0.775 nM, respectively and mouse GCGR, GIPR, and GLP-1R with EC50 values of 2.32, 0.191 and 0.794 nM, respectively. It is an important tool for obesity research.Retatrutide potently activates the GLP-1R signaling pathway to stimulate glucose-dependent insulin secretion through activity at the GIP receptor (GIPR) or the GLP-1R.Retatrutide is a synthetic peptide with glucose-lowering effects. It is an antidiabetic agent against type 2 diabetes (T2D), stimulating insulin and suppressing glucagon secretion in a glucose-dependent manner.Retatrutide was also shown to delay gastric emptying, lower fasting and postprandial glucose concentration, decrease food intake and reduce body weight in patients with type 2 diabetes.
