5-Amino-1MQ

5-Amino-1-methylquinolinium

5-Amino-1MQ is a small molecule — honestly, not a peptide — that blocks an enzyme called NNMT (nicotinamide N-methyltransferase). NNMT sits at a crossroads of cellular energy metabolism, and inhibiting it has become an active area of metabolic research. The compound is studied as a way to nudge fat tissue and energy expenditure through a quite different mechanism than the incretin agonists.
