Cellular-Aging Research Compounds: NAD+, Epithalon, MOTS-c
Cellular-aging research compound is one of the loosest class labels in a peptide catalogue, because it groups materials by the research area they appear in rather than by any shared chemistry. The three examples here, a dinucleotide coenzyme, a short pineal-derived tetrapeptide, and a mitochondria-derived peptide, have almost nothing structurally in common. This note explains what the grouping does and does not mean and shows only the identity fields documented for each.
A grouping by research context, not structure
These materials are collected because literature has examined them in the context of cellular-aging research, a broad area covering processes studied in cell and preclinical models. The label is a pointer to that literature. It is emphatically not a claim that any of these compounds slows, reverses, or affects aging in any subject, and the marketing-adjacent language that often surrounds this category is exactly what a research write-up must avoid. The responsible register is attributive: a compound has been investigated in the context of a pathway or process, and research interest has centred on a particular question. That reports the study without asserting the result.
Because the three are chemically unrelated, the class is useful only as a first filter. Every meaningful decision returns to the individual identity record.
Three distinct identity records
Only documented fields are shown. NAD+ has a molecular formula in its supplied record and it is included; for Epithalon and MOTS-c no formula or mass is part of the record, so none is stated.
| Field | NAD+ | Epithalon | MOTS-c |
|---|---|---|---|
| Class descriptor | Dinucleotide coenzyme | Pineal-derived tetrapeptide | Mitochondria-derived peptide |
| Sequence descriptor | Coenzyme, not a peptide chain | Ala-Glu-Asp-Gly | 16 amino acids |
| Molecular formula | C21H27N7O14P2 (as supplied) | Not stated in record | Not stated in record |
| CAS number | 53-84-9 | 307297-39-8 | 1627580-64-6 |
| Reported purity | 99.0% | 99.5% | 99.2% |
| Catalogue sizes | 100 mg, 500 mg | 10 mg, 50 mg | 10 mg, 25 mg |
NAD+ is a coenzyme rather than a peptide, which is why its sequence field is not a residue string; its supplied record includes the formula C21H27N7O14P2. Epithalon is documented as a four-residue tetrapeptide with the sequence Ala-Glu-Asp-Gly. MOTS-c is documented as a sixteen-residue mitochondria-derived peptide, and because no full residue string is supplied, the honest descriptor stops at the residue count and the class. The single table makes the diversity plain: one small molecule coenzyme and two peptides of very different lengths, sharing a research heading and little else.
Why the differences matter at receiving
A shared class heading can mask the fact that these materials are checked against different reference data. NAD+ can be cross-checked against its formula and CAS number; Epithalon against its short, fully specified sequence and CAS number; MOTS-c against its residue count, class, and CAS number. Treating them identically because they share a shelf is how a mismatch slips through. The CAS number is the common anchor that works across all three.
Chemical diversity within one heading
It is worth dwelling on just how different these three materials are, because the shared label can flatten that in a reader’s mind. NAD+ is a small-molecule coenzyme built from two nucleotides; it is not a peptide at all, and describing it with a residue sequence would be a category error. Epithalon is a genuine peptide, but a very short one, four residues fully specified as Ala-Glu-Asp-Gly, which means its entire primary structure fits in a single line and can be confirmed directly. MOTS-c is a peptide roughly four times that length, documented at sixteen residues, where the supplied record gives a count and a class rather than a spelled-out chain. Three materials, three completely different identity footprints, one research heading.
The documentation discipline that follows is simple to state and easy to violate under time pressure. Cite the fields that are supplied, in the form they are supplied, and leave blank what is not. For NAD+ that includes the formula C21H27N7O14P2 as given; for Epithalon it includes the full tetrapeptide sequence; for MOTS-c it stops at the residue count and class. Resisting the urge to complete a record from a plausible-looking source is the single habit that keeps a cellular-aging inventory defensible, precisely because this is a category where confident, under-sourced claims are common in the surrounding literature.
Handling and neutral framing
All three are supplied as research-use-only reference materials in lyophilized form and are handled cold and dry, protected from light and moisture. As with every class overview, this note carries no preparation amounts, concentrations, schedules, or routes. The point of the grouping is to help a researcher locate relevant preclinical literature, then to hand the decision back to the identity record and the certificate. For the underlying methodology, the note on interpreting mechanism-of-action literature explains how to keep observations separate from the interpretation and extrapolation that often inflate reports in this exact category.
Product-level records for NAD+, Epithalon, and MOTS-c list each material’s documented fields, and the grouping sits with the others in the compound classes archive. Read with that discipline, cellular-aging research compound stays a neutral filing category rather than a claim about what any of these materials can do.
The broader lesson generalises past these three. Any class heading that names a research area rather than a mechanism will collect materials that differ more than they resemble one another, and the more evocative the heading, the more careful a write-up has to be. Cellular aging is about as evocative as these headings get, which is exactly why the surrounding literature is dense with confident restatements that outrun their sources. The defensible posture is unglamorous and consistent: describe what was studied, in whose model, at what level of documentation, and hand every vial-level decision back to the identity record and the certificate. That posture is what lets a laboratory work in this category at all without importing claims it cannot support.
Common questions
Do these compounds slow or reverse aging?
No such claim is made or implied. The label groups materials that literature has examined in cellular-aging research contexts. It is a pointer to that research area only, and these compounds are supplied strictly for laboratory research use.
Why is NAD+ grouped with two peptides?
The grouping is by research context, not chemistry. NAD+ is a dinucleotide coenzyme, Epithalon is a tetrapeptide, and MOTS-c is a sixteen-residue peptide. They share a research heading while differing completely in structure.
What identifies MOTS-c if no formula is listed?
Its documented record covers the class descriptor, a sixteen amino acid sequence descriptor, the CAS number 1627580-64-6, and reported purity. No molecular formula is stated because none is part of the supplied data.
