5-Amino-1MQ: The Small Molecule Behind NNMT and NAD Research
A plain-English authority guide to 5-Amino-1MQ, the membrane-permeable NNMT inhibitor studied in NAD salvage and metabolic-ageing research. Supplied in Australia for laboratory and research use only, with a verified Novagen Certificate of Analysis on every batch.
What 5-Amino-1MQ actually is
5-Amino-1MQ, full chemical name 5-amino-1-methylquinolinium, is a small synthetic molecule studied as a selective inhibitor of the enzyme nicotinamide N-methyltransferase, almost always shortened to NNMT. It sits inside most research peptide catalogues, but it is worth being precise from the start: it is not a peptide. It is a compact quinolinium-based compound.
That small size is the whole point of why researchers reach for it. NNMT is an intracellular enzyme, meaning it works inside the cell, so any molecule that wants to influence it has to cross the cell membrane first. 5-Amino-1MQ is membrane-permeable, which is exactly why it moved NNMT inhibition from a theoretical target on paper into something that could be tested in living cell and animal models.
You will see 5-Amino-1MQ listed next to research peptides, but chemically it belongs to a different family. It is a small molecule that inhibits an enzyme, not a peptide that signals through a surface receptor. Keeping that distinction clear helps when reading the literature.
5-Amino-1MQ at a glance
- Chemical class: small-molecule quinolinium compound
- Primary target: the NNMT enzyme
- Connected pathway: NAD salvage and the SAM methylation cycle
- Typical research format: lyophilised powder for reconstitution in a laboratory
- Handling status: research use only, not for human or veterinary consumption
Mechanism and molecular targets
To understand why 5-Amino-1MQ is studied, you first have to understand what NNMT does. NNMT takes a methyl group from SAM, short for S-adenosyl-L-methionine, and attaches it to nicotinamide. That reaction produces two by-products: 1-methylnicotinamide, often written as 1-MNA, and S-adenosyl-L-homocysteine, written as SAH.
This matters for two separate reasons that both feed into ageing and metabolism research. First, nicotinamide is a raw material the cell normally recycles back into NAD, the coenzyme that sits at the centre of cellular energy production, through what is called the salvage pathway. When NNMT is highly active it siphons nicotinamide away into 1-MNA instead. Second, the reaction burns through SAM, the cell's main methyl donor, which shifts the wider methylation balance.
5-Amino-1MQ is studied as a competitive inhibitor that occupies the nicotinamide binding pocket of NNMT and slows that methylation step. The research question is straightforward to state: if you turn NNMT activity down, do you preserve more nicotinamide for NAD regeneration and change the SAM to SAH ratio in a measurable way? That is what the cell and animal work is designed to probe.
Unlike many research peptides that bind a cell-surface receptor, 5-Amino-1MQ has no classic receptor target. Its molecular target is the NNMT enzyme itself. The downstream nodes researchers track are the NAD salvage pathway and the methylation cycle, not a receptor signalling cascade.
Targets and pathway nodes studied
- NNMT enzyme: the direct molecular target of the inhibitor
- Nicotinamide and the NAD salvage pathway: the recycling route the enzyme competes with
- The SAM to SAH methylation cycle: the methyl-donor economy the enzyme draws on
- Adipocyte and metabolic signalling: where NNMT is often found overexpressed in obesity models
What 5-Amino-1MQ is studied for
The bulk of the published interest in 5-Amino-1MQ sits in metabolic ageing and adipose tissue biology, which is fat tissue. The reason is that NNMT is frequently reported as overexpressed in white adipose tissue in diet-induced obesity models, so it became an attractive enzyme to probe with a targeted inhibitor.
Research areas where 5-Amino-1MQ appears
- Metabolic ageing and cellular energy metabolism
- Adipocyte size, lipid handling and fat tissue biology in diet-induced obesity models
- NAD salvage and the maintenance of cellular NAD pools
- The SAM methylation cycle and methyl-donor availability
- Muscle and stem-cell ageing studies where NNMT activity is implicated
Everything above describes what scientists investigate in cells and animal models. None of it is a statement about what the compound does for a person, and none of it should be read as a benefit, a result or a reason to use the compound. 5-Amino-1MQ is supplied strictly for laboratory research.
The research landscape and where the evidence sits
5-Amino-1MQ entered the literature through medicinal-chemistry work aimed at finding small molecules that could inhibit NNMT in a cell-permeable way. Neelakantan and colleagues described 5-Amino-1MQ as a cell-permeable NNMT inhibitor and reported observations in diet-induced obese mouse models in work published around 2017 to 2018, which is the foundation most later references build on.
It is important to characterise that evidence base honestly. The work to date is early-stage and preclinical, meaning it lives in cell lines and rodent models. There is no large body of human clinical trial data behind 5-Amino-1MQ, and any authority guide that implies otherwise is overselling it. That is precisely why the compound remains a research tool rather than an approved product.
The strength of the 5-Amino-1MQ story is that it gave researchers a clean way to test NNMT inhibition in living models. The limit is that the data is mostly rodent and cell based. Extrapolating those findings to people is not supported, which is one more reason the compound is handled as a research chemical only.
How 5-Amino-1MQ is handled in a laboratory context
As a research chemical, 5-Amino-1MQ is typically supplied as a lyophilised powder in a sealed vial, ready to be reconstituted in a laboratory using an appropriate solvent for the intended assay. The points below describe how a research chemical of this kind is generally managed. They are laboratory handling considerations, not instructions for any person to follow.
General laboratory handling considerations
- Storage: research powders are commonly kept cold and protected from light and moisture until use
- Reconstitution: prepared in a lab with a solvent suited to the experiment, then aliquoted to limit freeze-thaw cycles
- Labelling: every vial and aliquot marked with compound name, batch or lot number and date
- Documentation: reconstitution details and concentrations recorded so results stay traceable
- Disposal: handled in line with the facility's chemical waste procedures
NovaPeptides does not publish protocols, doses or administration guidance for 5-Amino-1MQ, because it is not for human or animal use. Experimental design, concentrations and handling are the responsibility of the qualified researcher working within their own approved and lawful protocol.
Sourcing, purity and how to verify a batch
For a research chemical, identity and purity are not optional extras, they are the whole basis of a usable result. If the material in the vial is not what the label says, or carries significant impurities, any data generated from it is compromised before the first assay is run. This is why a genuine Certificate of Analysis, a COA, matters more than any marketing copy.
What a proper Certificate of Analysis should show
- Identity confirmed by mass spectrometry, so the molecule matches 5-amino-1-methylquinolinium
- Purity measured by HPLC, reported as a percentage
- A batch or lot number that ties the certificate to the specific vial
- The date of testing and the identity of the testing laboratory
- A result you can actually cross-check, not a generic image reused across products
Every batch of 5-Amino-1MQ supplied by NovaPeptides is backed by a verified Novagen Certificate of Analysis. That means the identity and purity of the material can be checked against independent lab testing tied to the batch, rather than taken on trust.
When assessing any Australian supplier of research compounds, treat a batch-specific, verifiable COA as the minimum bar. A supplier that cannot produce current, lot-matched testing for the exact material being shipped is asking you to run science on an unknown, and that is the fastest way to waste both budget and time.

Frequently asked questions
What is 5-Amino-1MQ?+
5-Amino-1MQ, or 5-amino-1-methylquinolinium, is a small synthetic molecule studied as a selective inhibitor of the enzyme nicotinamide N-methyltransferase, known as NNMT. It is investigated in cellular metabolism and metabolic-ageing research. It is supplied for laboratory and research use only.
Is 5-Amino-1MQ a peptide?+
No. Even though it is listed alongside research peptides, 5-Amino-1MQ is not a peptide. It is a small quinolinium-based molecule. Its small size is what lets it cross the cell membrane and reach NNMT, which is an enzyme that works inside the cell.
What does 5-Amino-1MQ do to NNMT?+
In research models, 5-Amino-1MQ is studied as a competitive inhibitor that occupies the nicotinamide binding site of NNMT and slows the enzyme's methylation reaction. This is a description of the compound's studied mechanism in the laboratory, not an outcome for any person.
How is 5-Amino-1MQ related to NAD?+
NNMT normally consumes nicotinamide, which cells otherwise recycle back into NAD through the salvage pathway. Because 5-Amino-1MQ is studied for slowing NNMT, researchers investigate whether inhibiting the enzyme preserves nicotinamide for NAD regeneration. This is an active research question, not a proven effect in people.
What is 5-Amino-1MQ studied for?+
The published research interest sits mainly in metabolic ageing, adipose tissue biology, the NAD salvage pathway and the SAM methylation cycle, because NNMT is often overexpressed in fat tissue in obesity models. These are laboratory research areas, not benefits or results for a person.
Is 5-Amino-1MQ approved for human use in Australia?+
No. 5-Amino-1MQ is not approved by the TGA for human use. NovaPeptides supplies it for laboratory and research use only. It is not for human or veterinary consumption and no therapeutic or performance claims are made.
Can I buy 5-Amino-1MQ for research in Australia?+
NovaPeptides supplies 5-Amino-1MQ to researchers in Australia strictly as a research use only compound. It is intended for qualified researchers conducting laboratory work within their own lawful and approved protocols, not for personal use.
Does every batch of 5-Amino-1MQ come with a Certificate of Analysis?+
Yes. Every batch supplied by NovaPeptides is backed by a verified Novagen Certificate of Analysis. The COA confirms identity by mass spectrometry and purity by HPLC, and is tied to the specific batch or lot number so it can be cross-checked.
How is 5-Amino-1MQ stored and handled in a lab?+
As a research powder it is generally kept cold, protected from light and moisture, reconstituted in a laboratory with an appropriate solvent and aliquoted to limit freeze-thaw cycles. These are general handling considerations for the compound as a research chemical, not instructions for any person.
How is 5-Amino-1MQ different from NAD or NMN?+
NAD and NMN are studied as direct inputs to the NAD pool. 5-Amino-1MQ works from a different angle: it is studied for inhibiting NNMT, the enzyme that diverts nicotinamide away from NAD recycling. So the research interest is in preserving the salvage pathway rather than supplying NAD precursors directly.
Where is NovaPeptides based and how long has it supplied researchers?+
NovaPeptides is Australian owned and based on the Gold Coast, and has supplied research peptides and compounds to Australian researchers for over three years, with a verified Novagen Certificate of Analysis on every batch.
