SMILES: O=C(N[C@@H](CSSC[C@](C(N[C@@H]1C)=O)([H])NC([C@@H](NC(C)=O)CCCNC(N)=N)=O)C(N)=O)[C@@H](NC([C@@H](NC([C@@](NC([C@@H](NC1=O)CC2=CN=CN2)=O)([H])CC3=CC=CC=C3)=O)CCCNC(N)=N)=O)CC4=CNC5=CC=CC=C45
Biological Activity: Setmelanotide (RM-493) is a blood-brain barrier-permeable, selective MC4R agonist with a Ki value of 2.1 nM for hMC4R. Setmelanotide activates the CaMKK2/AMPK signaling pathway. Setmelanotide mediates body weight homeostasis, feeding regulation and energy expenditure modulation; it reduces food intake, induces weight loss, decreases obesity severity, increases daytime activity and energy expenditure, lowers levels of leptin, triglycerides, fasting insulin and diastolic blood pressure, improves insulin sensitivity, glucose tolerance and fatty liver condition, and reverses respiratory depression. Setmelanotide is applicable to research related to obesity, hyperinsulinemia, fatty liver and respiratory depression[1][2][3][4][5].
