What is Cerluten A-5?
Short answer: Cerluten A-5 is a tissue-derived peptide bioregulator complex associated with brain and CNS research materials in the Khavinson programme. It is not a single defined molecule, and it has no verified PubChem CID or CAS number under the name Cerluten. The Cerluten A-5 product page lists Capsules Dry-Fill research material at 10 mg per capsule, 60 capsules per bottle.
Key takeaways for researchers
In brief: Treat Cerluten A-5 as a named peptide complex, keep it chemically separate from defined short peptides, and use peer-reviewed programme literature without inventing a registry identity.
- Cerluten A-5 is a peptide bioregulator complex, not a single sequenced molecule.
- PubChem has no compound CID for the name Cerluten; PubMed returns no Cerluten records.
- Programme reviews discuss peptide bioregulators as a research class (for example PubMed 24003726 and DOI 10.1007/s10522-009-9249-8).
- Cortexin literature describes a cerebral-cortex polypeptide complex and related short peptides; that is related programme chemistry, not a Cerluten trial series.
- Defined contrasts such as Pinealon (Glu-Asp-Arg) have PubChem identities; Cerluten A-5 does not inherit them.
- Modern Aminos lists Capsules Dry-Fill format with lot documentation when posted; all applicable tests are performed on our products.
Research timeline
- 2009 — Anisimov and Khavinson review peptide bioregulation of aging, including isolation of small peptides and synthetic analogues (DOI 10.1007/s10522-009-9249-8).
- 2013 — Khavinson, Kuznik and Ryzhak summarize clinical-programme results for named peptide preparations including Cortexin (PubMed 24003726).
- 2014 — Short peptides Glu-Asp-Arg and Lys-Glu-Asp are reported in brain-cortex culture chemistry (PubMed 24909721; DOI 10.1007/s10517-014-2496-y). Separately, Cortexin and peptide T-33 appear in neuronal-culture marker work (PubMed 25257443).
- 2019 — Kuznik and colleagues describe Cortexin as a cerebral-cortex polypeptide complex and model short-peptide derivatives (PubMed 31099784).
- Today — Cerluten A-5 remains without a PubChem compound record under that name. See the Cerluten A-5 product page and COA Search for lot documentation when posted.
Chemical identity
Cerluten A-5 does not have a single 2D structure, SMILES string, or InChIKey, because it is a peptide complex rather than one molecule. Template figures that embed a PubChem PNG apply to defined compounds; they are omitted here on purpose. For a defined brain-associated contrast, Pinealon is Glu-Asp-Arg under PubChem CID 10273502.
Programme chemistry and what it does not prove
Peptide bioregulator reviews discuss short peptides and tissue preparations in connection with gene expression and protein synthesis. Cortex-complex papers describe Cortexin and related short peptides. Reasonable inference: those sources justify treating tissue-derived complexes and synthetic short peptides as different chemical objects. They do not supply a Ki, IC50, crystal structure, or PubChem CID for Cerluten A-5.
Published numbers at a glance
| Item | Detail | Source |
|---|---|---|
| Cerluten PubChem CID | None under the name Cerluten | PubChem name lookup (404) |
| Cerluten CAS | None verified | Registry check; no PubMed Cerluten hits |
| Cerluten sequence | Not a single verified sequence | Complex identity class |
| Pinealon (contrast) | Glu-Asp-Arg; CID 10273502 | PubChem |
| Cartalax (contrast; not Cerluten) | Ala-Glu-Asp; CID 87815447 | PubChem |
| Cortexin (programme complex) | Cerebral-cortex polypeptide complex | PubMed 31099784 |
What this tells us: Cerluten A-5 should be catalogued and assayed as a complex. Importing a defined-peptide CID or sequence onto the Cerluten name is an identity error, not a convenience.
Cerluten A-5 compared with Pinealon-class short peptides
Pinealon is a defined tripeptide with a PubChem record. Cortagen is described as Ala-Glu-Asp-Pro in short-peptide literature (no public Modern Aminos product URL at drafting). Cerluten A-5 is named as a peptide complex. The practical laboratory difference is whether a certificate can match one sequence and exact mass, or only characterize a multi-component lot. More listings sit in the bioregulators collection.

Frequently asked questions
What is Cerluten A-5?
Cerluten A-5 is a tissue-derived peptide bioregulator complex associated with brain and CNS research materials in the Khavinson programme. It is not a single defined molecule: PubChem has no compound CID under the name Cerluten, and PubMed indexes no records for that string.
Is Cerluten A-5 a peptide?
Cerluten A-5 is peptide material in the sense that it is described as a peptide complex, meaning a mixture of peptides rather than one sequenced chain. That is different from a defined peptide such as Pinealon (Glu-Asp-Arg), which has one sequence and one PubChem CID.
How do tissue-derived peptide complexes differ from synthetic short peptides?
Tissue-derived peptide complexes are multi-component fractions without one amino-acid sequence or PubChem CID. Synthetic short peptides are single defined sequences that can carry CAS, formula, and molecular-weight records. Reasonable inference: certificates and assay targets differ for the two classes.
Is Cerluten A-5 the same as Pinealon or Cortagen?
No. Pinealon is Glu-Asp-Arg (PubChem CID 10273502). Cortagen is described as Ala-Glu-Asp-Pro in Khavinson short-peptide literature. Cerluten A-5 is named as a complex and does not inherit those sequences.
Does Cerluten A-5 have a CAS number or PubChem CID?
No verified CAS number or PubChem CID is indexed under the name Cerluten. Do not import Cartalax (Ala-Glu-Asp, CID 87815447) or other defined-peptide identifiers onto Cerluten A-5.
How is Cerluten A-5 documented for laboratory research?
All applicable tests are performed on our products. Lot certificates, when posted, appear on the product page Certificate of Analysis tab and can be looked up on the COA Search page. Capsules Dry-Fill supply is 10 mg per capsule, 60 capsules per bottle.

Cerluten A-5 belongs in a research panel as a named peptide complex. Keep its documentation honest about what is unknown, and keep defined short peptides on their own PubChem rails.
