Vesugen

Bioregulatory Tripeptide

also known as KED, Lys-Glu-Asp, Vezugen, T-38

Synthetic tripeptide (Lys-Glu-Asp) from the Khavinson bioregulatory peptide school. Designed for vascular endothelium targeting. Animal models demonstrate normalisation of endothelin-1 expression in atherosclerotic and restenotic vessels, restoration of connexin-mediated cell interactions, and stimulation of Ki-67-associated proliferation in aged endothelial cells. Proposed mechanism: epigenetic modulation via promoter binding to MKI67 and endothelial marker genes. Clinical data limited to Russian-language case series in elderly populations with vascular insufficiency.

§ II

Mechanism

Edit ↗

Primary target — Vascular endothelial cell nucleus — MKI67 gene promoter.

Pathway — KED → MKI67 promoter interaction (CATC binding motif -14 to +12 bp) → Ki-67 proliferation protein ↑.

Downstream effect — Normalised endothelin-1 expression in atherosclerotic/restenotic endothelium, restored connexin expression for cell-cell communication, enhanced proliferative capacity in senescent endothelial cultures [kozlov-2016][khavinson-2014].

Origin — Khavinson bioregulatory peptide school — designed as tissue-specific (vascular) cytomodulator.

Feedback intact — Not applicable — does not operate via hormone axis.

Assumed minimal — typical for small peptides
Long-term safetymoderate
Unknown — no long-term RCT data
Epigenetic mechanism riskmoderate
Theoretical concern: direct gene promoter interaction — proliferative effects in non-target tissues not characterised
Relative contraindications
  • Active malignancy — proliferative mechanism (Ki-67 upregulation) untested in oncologic context

Administration

Edit ↗
  1. 01
    Preparation

    Lyophilised powder reconstituted with sterile water or bacteriostatic water per supplier protocol. No standardised formulation.

  2. 02
    Injection site

    Subcutaneous (abdomen, thigh) or intramuscular. Rotate sites if multi-dose protocol.

  3. 03
    Timing

    No reported circadian or fasting requirement. Russian protocols typically integrated into geroprotective regimens.

  4. 04
    Storage

    Lyophilised: refrigerate 2–8 °C, light-protected. Reconstituted: use immediately or refrigerate per supplier guidance (typically <7 days).
