5 Amino 1MQ

5-AMINO-1MQ

5-Amino-1MQ is one of those compounds that often gets grouped in with peptides, but chemically, it isn’t a peptide at all.

Its full name is 5-amino-1-methylquinolinium, and it belongs to a class of small molecules developed to inhibit an enzyme called nicotinamide N-methyltransferase, or NNMT.

And NNMT is where the story gets interesting.

NNMT interacts with some extremely important metabolic chemistry.

It uses nicotinamide — a form of vitamin B3 — and a molecule called SAM, or S-adenosylmethionine, in a methylation reaction.

Why does that matter?

Because nicotinamide is also part of the pathway the body uses to make NAD+ — one of the most important molecules involved in cellular energy metabolism.

That led researchers to ask a fascinating question:

What happens if you inhibit NNMT and change the way those metabolic resources are being used?

Interest in that question exploded after a landmark 2014 study in Nature found that reducing NNMT activity in the liver and fat tissue of mice altered cellular metabolism and protected the animals against diet-induced obesity.

Researchers subsequently developed small molecules capable of directly inhibiting NNMT.

One of those molecules was 5-Amino-1MQ.

And this is where the compound started attracting serious attention.

In laboratory models, researchers have investigated NNMT inhibition in relation to:

• Cellular energy metabolism
• NAD+ biology
• SAM and methylation pathways
• White adipose tissue
• Fat-cell size
• Body-composition changes
• Glucose metabolism
• Insulin signaling
• Liver-fat accumulation
• Mitochondrial and metabolic function
• Age-related skeletal-muscle biology
• Muscle stem-cell activity
• Muscle regeneration

One of the early studies produced an especially interesting observation.

Researchers reported reductions in body weight, white-fat mass, and fat-cell size without a corresponding reduction in food intake.

That distinction made researchers pay attention.

For laboratory research only.
