What is 5-Amino-1MQ?
5-Amino-1MQ (5-amino-1-methylquinolinium) is a small-molecule, membrane-permeable, selective inhibitor of nicotinamide N-methyltransferase (NNMT) — a quinolinium compound, not a peptide. It was developed as a research-tool NNMT inhibitor (Watowich/Neelakantan, UT Medical Branch / Ridgeline Therapeutics). NNMT methylates nicotinamide using S-adenosylmethionine (SAM) to make 1-methylnicotinamide and S-adenosylhomocysteine; by inhibiting NNMT (IC50 ~1 µM), 5-Amino-1MQ relieves this SAM ‘methyl sink’ and preserves nicotinamide for NAD+ salvage. In preclinical (rodent and cell) models this is associated with increased NAD+, higher energy expenditure, reduced lipogenesis and adiposity, and preserved lean mass — with weight and fat-mass reductions in diet-induced-obese mice occurring without reduced food intake. It is structurally a small molecule and has no amino-acid sequence. It is grouped here with metabolic research compounds such as NAD+ and MOTS-c, and it is one component of the Metabolic Blend (NAD+ / MOTS-c / 5-Amino-1MQ). All evidence is preclinical, and research-grade 5-Amino-1MQ is unapproved, Research Use Only material — not for human use. New to peptide research? Start with the basics →
Reported benefits:
- Selective NNMT inhibition (IC50 ~1 µM) that relieves the SAM methyl sink
- Preserves nicotinamide for NAD+ salvage — associated with increased NAD+ (preclinical)
- Higher energy expenditure and reduced lipogenesis/adiposity in rodent models
- Weight and fat-mass reduction in diet-induced-obese mice without reduced food intake; preserved lean mass
Common research dose: There is no validated or FDA-approved dose. Preclinical studies used rodent dosing schedules, but those do not translate into a human dose, and Prof. Peptide does not extrapolate one. It is supplied as a solid research chemical (commonly the iodide salt), so no reconstitution table applies, and no human mg or mg/kg schedule is published.

How does 5-Amino-1MQ work?
5-Amino-1MQ is a small-molecule, membrane-permeable, selective inhibitor of nicotinamide N-methyltransferase (NNMT) — a quinolinium compound, not a peptide. NNMT methylates nicotinamide using S-adenosylmethionine (SAM), producing 1-methylnicotinamide (1-MNA) and S-adenosylhomocysteine (SAH). By inhibiting NNMT (IC50 ~1 µM), 5-Amino-1MQ relieves that SAM 'methyl sink' and preserves nicotinamide for NAD+ salvage. The downstream metabolic effects below are all from preclinical (rodent and cell) models.
- NNMT Inhibition. 5-Amino-1MQ is a selective small-molecule inhibitor of nicotinamide N-methyltransferase (NNMT), with an IC50 of about 1 µM. It is a quinolinium compound and has no amino-acid sequence.
- Relieving the SAM Methyl Sink. NNMT methylates nicotinamide using S-adenosylmethionine (SAM), producing 1-methylnicotinamide (1-MNA) and S-adenosylhomocysteine (SAH). Inhibiting NNMT relieves this 'methyl sink' on SAM.
- Preserving Nicotinamide for NAD+ Salvage [1]. By reducing nicotinamide methylation, NNMT inhibition preserves nicotinamide for the NAD+ salvage pathway — associated in preclinical models with increased NAD+.
- Metabolic Effects in Rodent Models [1]. NNMT inhibition is associated with higher energy expenditure, reduced lipogenesis and adiposity, and preserved lean mass. In diet-induced-obese (DIO) mice, weight and fat-mass reductions occurred without reduced food intake.
What is 5-Amino-1MQ researched for?
5-Amino-1MQ's research base is entirely preclinical, centered on metabolic disease in rodents. The most directly relevant study dosed it once-daily for 28 days in diet-induced-obese mice; supporting work spans the discovery/structure-activity of the inhibitor series, reversal of high-fat-diet obesity by NNMT inhibitors, and a foundational genetic proof-of-concept for NNMT as a metabolic target. There are no human clinical trials.
- Diet-Induced Obesity in Mice [1]. Once-daily 5-Amino-1MQ for 28 days in diet-induced-obese mice improved body composition and glucose/insulin parameters, with liver-pathology and pharmacokinetic assessments; weight and fat-mass reductions occurred without reduced food intake (Babula et al. 2024). Preclinical.
- Discovery & Structure-Activity Relationship. The small-molecule NNMT inhibitor series was characterized in a structure-activity-relationship study (Neelakantan et al., J Med Chem 2017). Cited by name.
- High-Fat-Diet Obesity Reversal. Selective, membrane-permeable small-molecule NNMT inhibitors reversed high-fat-diet-induced obesity in mice (Neelakantan et al., Biochem Pharmacol 2018). Cited by name.
- Genetic Proof-of-Concept. NNMT knockdown using an antisense oligonucleotide (not a small molecule) protected against diet-induced obesity, establishing NNMT as a metabolic target (Kraus et al., Nature 2014). Cited by name.
How is 5-Amino-1MQ dosed?
There is no validated or FDA-approved dose for 5-Amino-1MQ. It is handled as a research chemical, and the only dosing in the literature comes from preclinical rodent studies.
Preclinical studies administered 5-Amino-1MQ on rodent dosing schedules (for example, once-daily dosing over 28 days in diet-induced-obese mice), but rodent regimens do not translate into a human dose, and Prof. Peptide does not extrapolate one. There is no established human protocol, no validated mg or mg/kg schedule, and — because the compound is supplied as a solid research chemical (commonly the iodide salt) rather than a reconstituted injectable peptide — no reconstitution table is provided. The research material is unapproved and for laboratory use only.
What are the side effects of 5-Amino-1MQ?
The human safety of 5-Amino-1MQ is not characterized. The available evidence is entirely preclinical (rodent and cell models), so there is no controlled human adverse-event data to summarize. This is an unapproved, Research Use Only research chemical and is not intended for human consumption; nothing here should be read as human-use guidance. Long-term safety is unknown.
How should 5-Amino-1MQ be stored?
- Solid (powder) form, commonly supplied as the iodide salt: store cold and desiccated, protected from light.
- Keep tightly sealed in the original container; protect from moisture and light.
- For long-term storage, store frozen (-20°C); short-term storage at 2–8°C is acceptable.
- If dissolved for laboratory use, keep the solution cold and protected from light, and handle promptly.
- Discard if the material is discolored or shows signs of degradation.
What are the limitations of 5-Amino-1MQ research?
This is the most important section to read carefully. Everything known about 5-Amino-1MQ comes from preclinical models, and it is a research chemical rather than an approved medicine.
The 5-Amino-1MQ evidence base is entirely preclinical — rodent and cell models. There are no human clinical trials, and long-term safety is unknown.
It is a small-molecule research chemical (an NNMT inhibitor on a quinolinium scaffold), not a peptide and not an approved drug. It is not FDA-approved, and the metabolic effects reported in mice have not been confirmed in humans.
