Cortagen

Cortagen is a synthetic tetrapeptide, H-Ala-Glu-Asp-Pro-OH (single-letter AEDP), of L-alanine, L-glutamic acid, L-aspartic acid and L-proline from the St. Petersburg (Khavinson) line of short peptide bioregulators — a single defined molecule, distinct from the brain-cortex polypeptide complex Cortexin. It is listed here strictly as an analytical reference entity — it is not sold, stocked, or certified by Lineará, and has no price or certificate of analysis. The data on this page is characterization only: molecular formula C17H26N4O9 and the values computed from it. No biological activity, mechanism, or use is described or implied.

Cortagen has the sequence Ala-Glu-Asp-Pro. A linear tetrapeptide, H-Ala-Glu-Asp-Pro-OH (single-letter AEDP), of L-alanine, L-glutamic acid, L-aspartic acid and L-proline with free termini. Formula C17H26N4O9. Identity is reconciled against PubChem CID 18439621: the stereo-defined InChIKey PLTRIMAUDDQYRV-NAKRPEOUSA-N derived from the sequence matches the deposited record exactly (molecular formula and full InChIKey), with no unassigned stereocentres. It is a single defined peptide and must not be conflated with Cortexin, an undefined brain-cortex polypeptide extract. No CAS or UNII is asserted. A computed 3D conformer is held pending the chemist sign-off.

Cortagen has the molecular formula C17H26N4O9, giving an average molecular weight of 430.41 g/mol and a computed monoisotopic mass of 430.1700 Da.

The CAS Registry Number for Cortagen is —. Its PubChem CID is 18439621 and its InChIKey is PLTRIMAUDDQYRV-NAKRPEOUSA-N.

Yes. Cortagen is a peptide — a chain of amino-acid residues joined by peptide bonds, 4 residues in length. Its identity is defined by that sequence and its molecular mass.

As a research material, Cortagen is typically handled as a lyophilized (freeze-dried) powder. It is kept desiccated and cold — commonly 2–8 °C for short periods and −20 °C for longer storage — and reconstituted in sterile or bacteriostatic water. This is storage and handling information only, not a use protocol.

No. Cortagen is listed here only as an analytical reference entity. It is not part of the Lineará formulary, has no price or certificate of analysis, and is not offered for sale.

No. Cortagen is presented strictly as characterization reference data. It is not a drug, is not approved for any human or veterinary use, and must not be administered to humans or animals.
