In 1971, Soviet biologist Vladimir Khavinson began a research program in St. Petersburg (then Leningrad) whose framework hypothesis sounded seemingly speculative: if the aging process is partly regulated by signals from the endocrine glands, then isolating these signals and administering them to old animals should extend their lifespan. Khavinson focused particularly on pineal gland<\/strong> \u2014 a gland producing melatonin, the activity of which decreases dramatically with age. He isolated a peptide fraction from the pineal extract, which he named epithalamine<\/strong>, and after decades of structural analysis, identified a short tetrapeptide representing its biological activity. This is how he was born Epithalon<\/strong> \u2014 a synthetic analogue of a peptide with the sequence Ala-Glu-Asp-Gly.<\/p>\n

Half a century later, Epithalon is one of the most frequently discussed anti-aging peptides in popular science literature and one of the most controversial in the gerontological community. On the one hand, there is a bibliography containing dozens of studies on animal models, suggesting an extension of life by 20\u201330%, a reduction in spontaneous carcinogenesis, and a delay in oestropause. On the other hand, almost all the literature comes from one research group (Khavinson syndrome and related), independent replications are rare, and human studies do not meet the standards of modern phase III clinical trials.<\/p>\n

This article gathers the current state of knowledge about Epithalon from a research perspective – what is known, what the data suggest, what remains hypothesized, and what the methodological limitations of the available literature are. It is part of a broader review anti-aging peptides<\/a>.<\/p>\n

Origin – from epithalamine to synthetic AEDG<\/h3>\n

Natural epithalamine<\/strong> (Epithalamin) is a mixture of peptides isolated from the pineal gland of calves – currently withdrawn from research due to difficulties in standardization. Epithalon<\/strong> is a synthetic tetrapeptide representing the biological activity of epithalamine, possible to produce while maintaining GMP\/RUO standards.<\/p>\n

Epithalon belongs to a broader class of peptides developed by the Institute of Bioregulation and Gerontology in St. Petersburg – peptides referred to in Russian literature as “bioregulators<\/strong>” or “Khavinson peptides<\/strong>“. Other peptides in this family include:<\/p>\n
