The Dossier

Research Notes

5-Amino-1MQ is a small-molecule methylquinolinium derivative — not a peptide — supplied as the iodide salt. It was rationally designed at the University of Texas Medical Branch as a membrane-permeable, selective inhibitor of the enzyme nicotinamide N-methyltransferase (NNMT).

It is a focused reference for metabolic laboratory work, studied for its interaction with NNMT and downstream NAD-related pathways.

Research Focus

  • Adipose-metabolism and fat-loss models
  • Metabolic-syndrome and glucose-handling models
  • Muscle-regeneration and sarcopenia models
  • NAD⁺ / SIRT1 longevity signaling
  • NNMT-overexpressing tumor models

Mechanism

5-Amino-1MQ is a substrate-competitive inhibitor of NNMT, competing with nicotinamide for the active site and blocking its SAM-dependent methylation. Inhibiting NNMT is characterized as preserving the intracellular nicotinamide pool — shunting it toward NAD⁺ salvage — while sparing methyl-donor capacity.

It is reported as selective for NNMT, without inhibition of related methyltransferases or the salvage enzyme NAMPT.
