About Epithalon
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide composed of the amino acid sequence Alanine-Glutamic acid-Aspartic acid-Glycine (Ala-Glu-Asp-Gly, or AEDG). It was developed as a synthetic analog of epithalamin, a peptide preparation derived from the pineal gland, by Russian researcher Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology.
The majority of Epithalon's research interest centers on two areas. First, studies have explored its potential to activate telomerase — the enzyme that adds repetitive sequences to the ends of chromosomes (telomeres), which naturally shorten with each cell division and are associated with cellular aging. Second, Epithalon has been studied for its role in regulating the pineal gland's production of melatonin, with research models examining its effects on circadian rhythm normalization, particularly in aged subjects where natural melatonin production has declined.
Research Applications
Epithalon is used in research investigating telomerase activity, telomere length dynamics, cellular senescence, circadian rhythm regulation, and pineal gland function. It is frequently studied alongside other longevity-focused compounds as part of broader investigations into mechanisms of biological aging.
