5-Amino-1MQ vs Glutathione

5-Amino-1MQ and Glutathione are studied in overlapping research areas, which is why they are frequently compared. This is a neutral side-by-side reference drawn from published preclinical literature and laboratory handling data.

Shared research areas:MetabolicCellular Longevity
ClassSmall-molecule NNMT inhibitor (methylquinolinium salt) — not a peptideEndogenous thiol tripeptide (γ-L-glutamyl-L-cysteinyl-glycine), reduced form
Molecular weightNot specified307.3 g/mol
CAS numberNot assigned / not specified70-18-8
Purity spec≥99%≥99%
Research areasMetabolic, Cellular LongevityCellular Longevity, Metabolic
Primary diluentBacteriostatic water (0.9% benzyl alcohol)Sterile water (USP grade)
Working windowCommonly worked with for several weeks at 2-8 °C in preserved diluent.Commonly worked with for about 1 week at 2-8 °C; frozen aliquots keep longer.
Lead degradation routeMicrobial growth in non-preserved diluent — a container problem rather than a molecular one.Oxidation of the cysteine thiol to glutathione disulfide (GSSG, about 612.6 Da), catalysed by trace Cu²⁺/Fe³⁺ and faster at neutral-to-alkaline pH.
Freeze–thawTolerant of freeze-thaw — there is no tertiary structure to lose. Aliquoting is still good practice to limit repeated exposure of the stock.Tolerates a few freeze-thaw cycles, but each thaw exposes the thiol to dissolved oxygen. Aliquot once and thaw each portion only once.
Light sensitivityNo specific light requirement beyond normal practice.Not strongly light-sensitive, but oxygen-sensitive: minimise headspace and avoid metal spatulas or metal-contaminated buffers.

How they actually differ

Comparing the two: 5-Amino-1MQ is small-molecule nnmt inhibitor (methylquinolinium salt) — not a peptide, while Glutathione is endogenous thiol tripeptide (γ-l-glutamyl-l-cysteinyl-glycine), reduced form — different molecular classes with different handling consequences; they call for different primary diluents (bacteriostatic water (0.9% benzyl alcohol) versus sterile water (usp grade)); their leading degradation routes differ (microbial growth in non-preserved diluent for 5-Amino-1MQ, oxidation of the cysteine thiol to glutathione disulfide (gssg, about 612.6 da), catalysed by trace cu²⁺/fe³⁺ and faster at neutral-to-alkaline ph. for Glutathione), so the storage precautions that matter are not the same; their practical working windows differ once reconstituted. The sections below set out each in full.

5-Amino-1MQ — origin

5-Amino-1MQ is a small quinolinium molecule characterised as a first-in-class inhibitor of NNMT (nicotinamide N-methyltransferase), an enzyme studied at the intersection of adipocyte metabolism and the cellular NAD+/methylation pool. It is not an amino-acid chain, which is why it sits apart from every peptide in this catalogue.

Glutathione — origin

Glutathione is the tripeptide γ-glutamyl-cysteinyl-glycine. The glutamate is joined through its side-chain (γ) carboxyl rather than the usual α link, which protects it from most peptidases. It was named by Frederick Gowland Hopkins in 1921, and its role in cellular redox chemistry was mapped out through the 20th century, most influentially in Alton Meister's work on the γ-glutamyl cycle.

5-Amino-1MQ research themes

NNMT inhibition

The defining mechanism — preclinical work has examined how blocking NNMT shifts methylation flux and NAD+ salvage in metabolic tissue models.

Adipocyte energy metabolism

Studied in fat-cell models for effects on cellular energy handling and lipid metabolism.

NAD+ economy

Because NNMT consumes a methyl group tied to the NAD+ precursor pool, it is studied alongside the wider NAD+ research field.

Glutathione research themes

Cellular redox buffering (GSH/GSSG ratio)

Glutathione is the most abundant low-molecular-weight thiol in most cells, and the ratio of reduced to oxidised glutathione is widely used as a read-out of oxidative stress in cell-culture and tissue studies.

The γ-glutamyl cycle

Meister and Anderson (Annu Rev Biochem 1983) reviewed glutathione synthesis by γ-glutamylcysteine synthetase and glutathione synthetase, and its breakdown by γ-glutamyl transpeptidase — the framework most synthesis and turnover studies still use.

Detoxification by glutathione S-transferases

GSTs conjugate glutathione to electrophilic compounds, and this conjugation step is a standard model in xenobiotic-metabolism research.

The glutathione peroxidase system

Glutathione peroxidases use GSH to reduce hydrogen peroxide and lipid hydroperoxides, with glutathione reductase recycling GSSG back to GSH using NADPH — a common model for studying peroxide handling in vitro.

5-Amino-1MQ handling

  • Let the sealed vial reach room temperature before opening so moisture does not condense onto the powder.
  • For cell-based assays, prepare a concentrated DMSO stock and dilute into aqueous buffer rather than dissolving directly at high concentration in medium.
  • Label aliquots with reconstitution date and diluent.

Glutathione handling

  • Let the vial reach room temperature before opening to stop condensation getting in.
  • Use degassed diluent where possible and cap promptly after drawing.
  • Avoid metal tools and buffers with trace copper or iron; plastic or glass only.
  • Label aliquots with reconstitution date and diluent.
