5-Amino-1MQ

Also known as 5-amino-1-methylquinolinium, NNMT inhibitor

Animal studies only

Not a peptide: a small molecule inhibitor of the enzyme nicotinamide N-methyltransferase (NNMT). Studied only in cell and mouse models of obesity; no published human trials.

Not an approved medicine. 5-Amino-1MQ is not an approved medicine for this use in Australia or the United States. This page summarises published research for information only. It is not a recommendation to use 5-Amino-1MQ, and VialOwl does not sell or supply it.

Background

A small molecule (5-amino-1-methylquinolinium), not a peptide, described by researchers at the University of Texas Medical Branch in 2017 and 2018 as part of a series of nicotinamide N-methyltransferase (NNMT) inhibitors studied as possible obesity drugs. Related work was carried out with Ridgeline Therapeutics, a company founded by one of the researchers.

How it is thought to work

It blocks the enzyme NNMT, which is abundant in fat tissue. In fat cells and mice this raised cellular NAD+ and SAM levels and reduced fat storage, but whether the same happens in people has not been tested.

What is claimed, and the evidence

ClaimEvidenceNotes
Fat loss and weight lossAnimal studies onlyReduced body weight and white fat mass in diet induced obese mice (2018) and with a low fat diet (2022). No published human trials.
Improved insulin sensitivity and blood sugar controlAnimal studies onlyReviews report improvements with NNMT inhibition or knockdown in rodents only; no clinical trials of NNMT inhibitors had been reported as of 2021.
Muscle preservation, energy and anti ageingNo published evidenceCommon marketing claims for oral capsules; no published human evidence.

Side effects

EffectHow oftenNotes
Human side effectsFrequency unknownNo human studies have been published, so side effects in people are unknown. The mouse study reported no observable adverse effects.
