What Is 5-Amino-1MQ?

5-Amino-1MQ (5-amino-1-methylquinolinium) is a small molecule rather than a peptide. It is studied as an inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme that methylates nicotinamide using S-adenosyl methionine. Because NNMT modulates the availability of nicotinamide, its inhibition is of interest in cellular metabolism research. The compound is described here as a research small molecule with a distinct chemical identity from the peptide catalogue.

Molecular Characteristics

• Classification: a small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT), not a peptide.
• Chemical class: an amino-substituted quinolinium derivative.
• Molecular weight: reported in Daltons (Da) on product documentation; the measured value should be compared against the theoretical mass.
• Physical form: supplied as a lyophilised (freeze-dried) powder, the standard presentation for research material.

How 5-Amino-1MQ Works

In laboratory models, 5-amino-1MQ inhibits NNMT, reducing the methylation of nicotinamide to N-methylnicotinamide. This shifts the disposition of nicotinamide within the cell, influencing pathways that depend on nicotinamide availability, including those linked to NAD+ turnover. Cellular studies have associated NNMT inhibition with altered adipocyte and metabolic-cell behaviour, though these findings remain preclinical.

These observations describe enzymatic inhibition in model systems and do not constitute a therapeutic use.

Areas of Scientific Research

• NNMT enzymology: characterisation of NNMT inhibition and nicotinamide methylation.
• Cellular metabolism: studies of nicotinamide disposition and NAD+ turnover in metabolic models.
• Inhibitor studies: comparison of NNMT inhibitors and their effects on metabolic-cell behaviour.

These investigations are conducted in vitro or in approved animal research models under institutional oversight. They do not translate to approved human use.

Analytical Testing

• HPLC for purity assessment, reported as a percentage of total peak area.
• Mass spectrometry for identity confirmation against the theoretical molecular mass.

Storage and Handling

In a laboratory context, lyophilised 5-amino-1MQ is typically stored in a freezer, protected from light and moisture, and handled according to the product-specific documentation. General guidance is covered in the peptide storage and stability reference.
