Epithalon

Synthetic tetrapeptide

Also known as Epitalon, Epithalone, Ala-Glu-Asp-Gly

A synthetic tetrapeptide developed in Russia, studied in cell culture for effects on telomerase expression and in animal models of ageing. The evidence base is largely from a single research institute.

How this compound is tested

A tetrapeptide is straightforward to characterise by LC-MS and HPLC. Researchers should be aware that the acidic residues make the peptide hygroscopic; water content affects net peptide content.

Research background

Epithalon was designed by Khavinson and colleagues at the St Petersburg Institute of Bioregulation and Gerontology as a synthetic analogue of the pineal extract "epithalamin". The published literature consists mainly of Russian-language and institute-authored studies in cell lines and rodents, with limited independent replication.

Mechanisms investigated in published research

These are the mechanisms examined in the cited literature. Describing them is not a claim that the compound produces any effect in humans.

  • Reported activation of telomerase in human somatic cell cultures.
  • Proposed effects on melatonin secretion and pineal function in animal models.
  • Reported changes in gene expression in cultured cells.
Summary of evidence

Laboratory and animal findings are kept separate from human clinical evidence.

Preclinical findings

Rodent lifespan and tumour-incidence studies and cell-culture telomerase studies from the originating institute. Independent, well-controlled replications are scarce.

Human clinical evidence

No peer-reviewed randomised controlled trials in a Western journal were identified. Institute-reported human studies lack the design features needed to draw conclusions.

Limitations and open questions
  • Single-source literature with limited independent replication.
  • Many primary sources are not indexed in major databases or are not in English.
  • Telomerase findings in vitro have not been linked to any validated outcome.
