5 AMINO 1MQ

Product Description

What is 5-Amino-1MQ?

5-Amino-1MQ (5-Amino-1-methylquinolinium) is a synthetic small molecule (not a peptide; MW ≈ 174.2 Da) developed through academic medicinal chemistry research. It is classified as a selective inhibitor of nicotinamide N-methyltransferase (NNMT), a cytosolic enzyme that catalyzes the N-methylation of nicotinamide using S-adenosyl-L-methionine (SAM) as a methyl donor. It is intended strictly for laboratory and research purposes.

Molecular & Structural Profile

5-Amino-1MQ is a quaternary ammonium compound based on the quinolinium scaffold, featuring an amino group at the 5-position and a methyl group at the nitrogen-1 position. Its mechanism of enzyme inhibition is characterized through competitive binding studies at the NNMT active site in biochemical assay models. As an NNMT inhibitor, it is studied in the context of NAD+ salvage pathway research and one-carbon metabolism in cellular biochemistry models.
