What Is 5-Amino-1MQ?
5-Amino-1MQ (5-amino-1-methylquinolinium) is a small-molecule research compound, not a peptide. It is studied as an inhibitor of nicotinamide N-methyltransferase (NNMT), an enzyme that has drawn significant attention in metabolic research. This guide frames it accurately as a small-molecule enzyme inhibitor, distinct from the peptides elsewhere in the library.
The NNMT Pathway: Methylation And NAD+
NNMT methylates nicotinamide using S-adenosylmethionine (SAM) as the methyl donor. This single reaction touches two important currencies at once: it consumes methyl groups (affecting the cell’s methylation capacity) and it diverts nicotinamide away from the NAD+ salvage pathway. When NNMT activity is high, more nicotinamide is methylated and cleared rather than recycled back into NAD+.
By inhibiting NNMT, 5-Amino-1MQ is studied for preserving the nicotinamide pool for NAD+ salvage and shifting cellular methylation balance. In adipocyte and metabolic models this is associated with increased energy expenditure, which is why NNMT inhibition is an active target in obesity and metabolic-dysfunction research.
- 5-Amino-1MQ is a small-molecule NNMT inhibitor, not a peptide.
- NNMT methylates nicotinamide using SAM, consuming methyl groups and diverting NAD+ precursors.
- Inhibiting NNMT is studied for preserving NAD+ salvage and raising adipocyte energy expenditure.
- A common target in obesity and metabolic-dysfunction research models.
Relationship To NAD+ Research
Because NNMT inhibition influences the NAD+ salvage pathway, 5-Amino-1MQ is frequently studied in the same context as NAD+ biology. Where NAD+ research asks how to maintain the coenzyme pool directly, NNMT-inhibitor research asks how to reduce the drain on its precursors. The two lines of inquiry are complementary in metabolic and longevity research.
Research Context And Handling
5-Amino-1MQ research uses NNMT enzyme-activity assays, NAD+/NADH quantification, and adipocyte metabolic readouts. As with any Research Use Only compound, verified identity and purity, appropriate storage, and interpretation against the primary literature are essential. It is supplied strictly for laboratory research and not for human or animal use.

Frequently Asked Questions
Is 5-Amino-1MQ a peptide?
No. 5-Amino-1MQ (5-amino-1-methylquinolinium) is a small molecule, not a peptide. It is studied as an inhibitor of the enzyme NNMT and is included in the library for its role in metabolic and NAD+ research.
What is NNMT and why inhibit it?
NNMT (nicotinamide N-methyltransferase) methylates nicotinamide using SAM, which consumes methyl groups and diverts nicotinamide away from NAD+ salvage. Inhibiting NNMT is studied for preserving the NAD+ precursor pool and raising adipocyte energy expenditure.
How is 5-Amino-1MQ related to NAD+ research?
Because NNMT inhibition preserves nicotinamide for NAD+ salvage, 5-Amino-1MQ is studied alongside NAD+ biology - one line asks how to maintain the NAD+ pool, the other how to reduce the drain on its precursors. Both are Research Use Only.
