Mazdutide (IBI362, LY330567) (P1231-GRP)

Mazdutide (IBI-362; LY-3305677) is a synthetic long-acting oxyntomodulin analog that functions as a dual agonist of glucagon-like peptide-1 receptor (GLP-1R) and glucagon receptor (GCGR). The compound exhibits binding affinity for human and mouse GCGR (Ki values of 17.7 nM and 15.9 nM, respectively) and GLP-1R (Ki values of 28.6 nM and 25.1 nM, respectively). In mouse islets, mazdutide stimulates insulin secretion with an EC50 of 5.2 nM. This agent has been investigated in research related to obesity and type 2 diabetes (T2D).
