5-Amino-1MQ: A Research Overview

5-Amino-1MQ (5-amino-1-methylquinolinium) is a research-grade small-molecule NNMT inhibitor — an inhibitor of the enzyme nicotinamide N-methyltransferase — studied in laboratory and preclinical animal models.

What Is 5-Amino-1MQ?

5-Amino-1MQ is a small molecule (not a peptide) studied as an inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme involved in NAD+ and methylation metabolism. It is used as a research-grade chemical tool to probe NNMT biology. In the lab it is typically supplied as a powder. The available data is entirely preclinical — in-vitro (enzyme and cell) assays and rodent studies; there are no published human clinical trials.

What the Research Describes

Mechanistic studies — in cells and animals — have investigated several overlapping pathways:

• NNMT enzyme inhibition, studied in vitro, where small-molecule inhibitors of the 1-methylquinolinium class reduced NNMT catalytic activity in biochemical and cell-based assays.
• Effects on NAD+ and SAM-related methylation metabolism, studied in cellular models (NNMT consumes S-adenosyl-methionine and methylates nicotinamide, intersecting the NAD+ salvage pathway).
• Adipocyte and metabolic-marker changes, studied in diet-induced obese (DIO) mouse models.
• Glucose-handling and insulin-sensitization markers, studied in animal models of metabolic disease using NNMT-inhibitor chemotypes.
• Muscle stem-cell activity and skeletal-muscle regeneration, studied in aged mice following induced injury.

These describe mechanisms observed in laboratory and animal research — not demonstrated effects in humans.

A Note on the Current Evidence

• The available evidence is entirely preclinical — in-vitro assays and rodent studies. There are no published human clinical trials of 5-Amino-1MQ.
• It is a research-grade small-molecule chemical tool used to probe NNMT enzyme biology; findings are mechanism- and model-level only.
• Reported mouse outcomes reflect specific experimental conditions and compound chemotypes and cannot be extrapolated to predict any effect in people.

Forms and Handling in Research

In a research setting 5-Amino-1MQ is handled as a lyophilized (freeze-dried) powder, commonly reconstituted with bacteriostatic water for laboratory use, stored cold and protected from light, and supplied with purity testing (e.g., HPLC) and lot documentation.

Research-Use and Legal Status

5-Amino-1MQ is sold and used as a research compound only. It is not an FDA-approved drug, not a dietary supplement, and not intended for human or animal consumption.
