A linear dipeptide, H-Lys-Glu-OH (single-letter KE), of L-lysine and L-glutamic acid joined by a single peptide bond, with free alpha-amino and alpha-carboxyl termini — non-amidated and non-cyclic. Its formula C11H21N3O5 follows from the two residues less one water. The alpha-linked L,L constitution is confirmed against PubChem: the stereo-defined InChIKey UGTZHPSKYRIGRJ-YUMQZZPRSA-N derived from the sequence resolves to the stereo-defined records (PubChem CID 7010501/7010502), and its connectivity block matches CID 14304541 — the CAS-linked N-L-lysyl-L-glutamic-acid record, which is deposited without stereochemistry. That connectivity match rules out the isopeptide isomers (gamma-glutamyl-lysine) that share the C11H21N3O5 formula and could not be distinguished by mass alone. A computed 3D conformer is held pending the launch-wide chemist sign-off.

Reference context

Vilon is a synthetic dipeptide, H-Lys-Glu-OH (single-letter KE), of L-lysine and L-glutamic acid from the St. Petersburg (Khavinson) line of short peptide bioregulators — the same research family as Epithalon and Pinealon. 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 C11H21N3O5 and the values computed from it. No biological activity, mechanism, or use is described or implied.

How Vilon is characterized

Identity rests on the molecular formula and mass. Electrospray mass spectrometry (ESI-MS) measures the mass-to-charge ratio of the intact molecule; the average and monoisotopic masses are computed from the verified formula and cross-check the composition. The residue sequence and the modifications noted above define the structure.

Frequently asked questions

What is Vilon?
Vilon is a synthetic dipeptide, H-Lys-Glu-OH (single-letter KE), of L-lysine and L-glutamic acid from the St. Petersburg (Khavinson) line of short peptide bioregulators — the same research family as Epithalon and Pinealon. 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 C11H21N3O5 and the values computed from it. No biological activity, mechanism, or use is described or implied.
What is the amino-acid sequence of Vilon?
Vilon has the sequence Lys-Glu. A linear dipeptide, H-Lys-Glu-OH (single-letter KE), of L-lysine and L-glutamic acid joined by a single peptide bond, with free alpha-amino and alpha-carboxyl termini — non-amidated and non-cyclic. Its formula C11H21N3O5 follows from the two residues less one water. The alpha-linked L,L constitution is confirmed against PubChem: the stereo-defined InChIKey UGTZHPSKYRIGRJ-YUMQZZPRSA-N derived from the sequence resolves to the stereo-defined records (PubChem CID 7010501/7010502), and its connectivity block matches CID 14304541 — the CAS-linked N-L-lysyl-L-glutamic-acid record, which is deposited without stereochemistry. That connectivity match rules out the isopeptide isomers (gamma-glutamyl-lysine) that share the C11H21N3O5 formula and could not be distinguished by mass alone. A computed 3D conformer is held pending the launch-wide chemist sign-off.
What is the molecular formula of Vilon?
Vilon has the molecular formula C11H21N3O5, giving an average molecular weight of 275.30 g/mol and a computed monoisotopic mass of 275.1481 Da.
What are the key chemical identifiers for Vilon?
The CAS Registry Number for Vilon is 45234-02-4. Its PubChem CID is 14304541, its FDA UNII is H34V7IM5ML, and its InChIKey is UGTZHPSKYRIGRJ-YUMQZZPRSA-N.
Is Vilon a peptide?
Yes. Vilon is a peptide — a chain of amino-acid residues joined by peptide bonds, 2 residues in length. Its identity is defined by that sequence and its molecular mass.
How is Vilon stored and reconstituted?
As a research material, Vilon 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.
Does Lineará sell Vilon?
No. Vilon 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.
Is Vilon approved for human use?
No. Vilon 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.
