5-Amino-1MQ vs IGF-1

5-Amino-1MQ and IGF-1 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:Metabolic
ClassSmall-molecule NNMT inhibitor (methylquinolinium salt) — not a peptide70-residue single-chain protein (native IGF-1), three disulfide bonds
Molecular weightNot specified7648.7 g/mol
CAS numberNot assigned / not specifiedNot assigned / not specified
Purity spec≥99%≥99%
Research areasMetabolic, Cellular LongevityHormonal & Endocrine, Musculoskeletal, Metabolic
Primary diluentBacteriostatic water (0.9% benzyl alcohol)Dilute acetic acid for initial dissolution
Working windowCommonly worked with for several weeks at 2-8 °C in preserved diluent.Short — days rather than weeks — and shorter still with repeated handling.
Lead degradation routeMicrobial growth in non-preserved diluent — a container problem rather than a molecular one.Misfolding and irreversible denaturation — the dominant failure mode.
Freeze–thawTolerant of freeze-thaw — there is no tertiary structure to lose. Aliquoting is still good practice to limit repeated exposure of the stock.Poorly tolerant. Repeated freeze-thaw denatures the folded structure permanently, so aliquot for single use rather than relying on any freeze tolerance.
Light sensitivityNo specific light requirement beyond normal practice.No specific light requirement beyond normal practice.

How they actually differ

Comparing the two: 5-Amino-1MQ is small-molecule nnmt inhibitor (methylquinolinium salt) — not a peptide, while IGF-1 is 70-residue single-chain protein (native igf-1), three disulfide bonds — different molecular classes with different handling consequences; they call for different primary diluents (bacteriostatic water (0.9% benzyl alcohol) versus dilute acetic acid for initial dissolution); their leading degradation routes differ (microbial growth in non-preserved diluent for 5-Amino-1MQ, misfolding and irreversible denaturation for IGF-1), 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.

IGF-1 — origin

IGF-1 is the native insulin-like growth factor — a folded 70-amino-acid protein stabilised by three internal disulfide bonds. It is the downstream messenger produced after growth hormone acts, and it is handled as a protein rather than a short peptide. This is the native sequence, distinct from the long-acting LR3 analogue.

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.

IGF-1 research themes

IGF-1 receptor signalling

Studied as the native ligand for the IGF-1 receptor and its downstream proliferation and survival pathways.

Satellite cell activation

Examined in muscle research models for its role in satellite-cell behaviour and anabolic signalling.

Native versus analogue

Compared with IGF-1 LR3, whose reduced binding-protein affinity gives a longer active window — a contrast studied directly in the literature.

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.

IGF-1 handling

  • Dissolve first in dilute acetic acid, then dilute into the working buffer — never expect plain water to take it up fully.
  • Use a carrier protein and low-bind labware to prevent adsorptive loss.
  • Aliquot for single use; do not re-freeze reconstituted protein.
