Mechanism of action

Competitive inhibition of NNMT → altered SAM / nicotinamide balance → downstream effects on adipose-tissue energy metabolism.

Research context

5-Amino-1MQ is a small-molecule inhibitor of NNMT (nicotinamide N-methyltransferase), the enzyme that methylates nicotinamide using SAM as methyl donor. NNMT is upregulated in adipose tissue in obesity; inhibition has been studied as a metabolic-research tool.

Published in 2018 by Neelakantan and colleagues. Purely preclinical at this stage.

FAQ

Why isn't this a peptide?+

It is a small molecule — a methylated quinolinium derivative. Included because it is commonly used alongside mitochondrial peptides in metabolic research.
