Livagen
Also known as: Lys-Glu-Asp-Ala
Livagen is a synthetic tetrapeptide (Lys-Glu-Asp-Ala / KEDA) from the Khavinson short-peptide 'bioregulator' series, developed at the St. Petersburg Institute of Bioregulation and Gerontology. Marketed in Russia primarily as a food-supplement-grade cytomax; not FDA-approved in the US; research-use only.

Overview of Epitalon-Highly Bioactive Pineal Tetrapeptide with Promising Properties
Epitalon, also known as Epithalon or Epithalone, is a tetrapeptide, Ala-Glu-Asp-Gly (AEDG), which was synthesized based on the amino acids composition of Epithalamin, a bovine pineal gland extract, prior to its discovery in pineal gland polypeptide complex solution.

EPIGENETIC MODIFICATION UNDER THE INFLUENCE OF PEPTIDE BIOREGULATORS ON THE "OLD" CHROMATIN
In the present study, on the one hand, the epigenetic modification of condensed "old" chromatin was determined, and on the other hand, the influence of peptide bioregulators (Ala-Glu-Asp-Gly-Epitalon; Lys-Glu-Asp-Ala-Livagen; Ala-Glu-Asp-Pro - Cortagen and Lys-Glu - Vilon) on condensed chromatin in lymphocytes from old…

[The influence of polypeptide liver complex and tetrapeptide KEDA on organism physiological function in norm and age-related pathology.]
The applying of many drugs in elderly and old people often is the reason of liver dysfunction. Thereat, the risk of liver fibroid induration, acute and chronic hepatitis increases during aging. It is the reason to find new, effective and harmless hepatoprotectors.

[EVALUATION OF GENOMIC PARAMETERS IN DUCTAL BREAST CANCER PATIENTS AND THE ABILITY OF IT'S CORRECTION]
The level of DNA single strand breaks, chromosomal abnormalities and sister chromatid exchanges and the possibility of its normalization with oligopeptide bioregulator Livagen and cobalt ions in the lymphocyte culture from patients with breast cancer have been studied.

Peptides (Epigenetic Regulators) in the Structure of Rodents with a Long and Short Lifespan
We have discovered motives of short-chain epigenetically active peptides in some proteins of long-lived African mole rat Heterocephalus glaber. These epigenetic regulators are located in the protein structure between lysine and arginine residues, thus facilitating their release in limited proteolysis.

[Effect of peptide bioregulator and cobalt ions on the activity of NORs and associations of acrocentric chromosomes in lymphocytes of patients with hypertrophic cardiomyopathy and their relatives]
The influence of peptide bioregulator - Livagen (Lys-Glu-Asp-Ala) separately and combined with cobalt ions, on the activity of nucleolar organizer regions (NORs) and frequency of associations of acrocentric chromosomes in lymphocytes from patients with hypertrophic cardiomyopathy (HCM) and their relatives has been stud…
