Research evidence guide
5-Amino-1MQ research starts with the complete chemical identity.
A cited guide to the quinolinium NNMT inhibitor, cation-versus-salt distinctions, assay evidence and current non-clinical research formats.
It is a small molecule, not a peptide
PubChem represents 5-amino-1-methylquinolinium as a positively charged heteroaromatic cation with formula C10H11N2+.[1] A separate PubChem record represents the iodide salt with formula C10H11IN2.[2] Those records illustrate why the counterion and formula-weight basis must be documented rather than inferred from “5-amino-1MQ.”
What NNMT research measures
NNMT transfers a methyl group from S-adenosylmethionine to nicotinamide and related pyridine substrates. A 2021 review identifies 5-amino-1-methylquinolinium as a nicotinamide-site inhibitor while cautioning that incomplete selectivity and metabolic-stability information can limit interpretation of available probes.[5]
Potency values are assay-specific
The cited primary work reported an NNMT IC50 near 1.2 micromolar under its particular biochemical conditions.[3][4] An IC50 is not an intrinsic product specification: enzyme construct, substrate concentrations, detection method and analysis all affect the value. It cannot be treated as a potency guarantee for a seller lot.
Keep cellular and animal findings in their models
The 2018 study reported changes in intracellular 1-methylnicotinamide, NAD+ and SAM in differentiated murine adipocytes, alongside short animal-model observations.[4] These findings do not establish human safety, efficacy, absorption or a consumer outcome.
Assay literacy for procurement
A validated LC-MS/MS method quantified the 5-amino-1-methylquinolinium analyte in rat plasma and urine.[6] Detecting the cation in a biological matrix does not identify a bulk material’s counterion and is not a substitute for raw-material identity, impurity or net-content testing.
Procurement essentials
- Confirm the full chemical name, counterion, molecular formula and formula-weight basis.
- Review whether the labeled quantity is stated on an as-is, salt, anhydrous or cation-equivalent basis.
- Request lot-matched identity and analytical documentation when available.
- Distinguish chromatographic purity, chemical identity, assay content, counterion confirmation and net mass.
- Keep published compound-level findings separate from seller and lot records.
