Mazdutide  (Synonyms: IBI-362; LY-3305677; OXM-3)

Mazdutide (IBI-362; LY-3305677) is a long-acting synthetic oxyntomodulin analog. Mazdutide is also a co-agonist of glucagon-like peptide (GLP-1R) and glucagon receptor (GCGR). Mazdutide binds human and mouse GCGR (K_i: 17.7 nM and 15.9 nM, respectively) and GLP-1R (K_i: 28.6 nM and 25.1 nM, respectively) and stimulates insulin secretion from mouse islets (EC₅₀: 5.2 nM). Mazdutide is used in studies of obesity and type 2 diabetes (T2D)^[1][2][3].

Mazdutide (15, 30 nmol/kg; sc; single dose) significantly reduces body weight and physical intake in diabetic mice with diet-induced obesity (DIO)^[3].
