Epitalon (Epithalon): Telomere and Longevity Research Guide

<p>Epitalon (also spelled Epithalon; sequence: Ala-Glu-Asp-Gly) is a synthetic tetrapeptide developed in Russia by Dr. Vladimir Khavinson and the St. Petersburg Institute of Bioregulation and Gerontology. It is a synthetic analog of the pineal gland peptide epithalamin. Epitalon has been studied primarily in the context of telomerase activation, telomere dynamics, and aging biology for over three decades, making it one of the most studied peptides in longevity research literature.</p><h2>Molecular Profile</h2><p>Sequence: Ala-Glu-Asp-Gly | Molecular Formula: C14H22N4O9 | MW: 390.34 g/mol | CAS: 307297-39-8</p><h2>Telomere Research Background</h2><p>Telomeres are repetitive DNA sequences (TTAGGG) at chromosome ends that protect genomic integrity during replication. Telomere length shortens with each cell division, and telomere attrition is considered a hallmark of cellular aging. Telomerase, the enzyme responsible for telomere elongation, is active in germ cells and stem cells but largely silenced in differentiated somatic cells.</p><p>Epitalon's primary area of published research involves its interaction with telomerase activity. In-vitro studies using human fetal fibroblast cell lines have demonstrated that exposure to epitalon increases telomerase activity and extends cell proliferative capacity — a finding that has generated sustained research interest.</p><p>↗ Khavinson V et al. (2003). Epithalon peptide induces telomerase activity and telomere elongation in human somatic cells. Bulletin of Experimental Biology and Medicine. PubMed ID: 12937682</p><h2>Pineal Gland and Circadian Research</h2><p>Epitalon's parent compound, epithalamin, was isolated from the pineal gland. The pineal gland's role in circadian rhythm regulation (via melatonin secretion) has made it a research interest in aging biology, given that pineal function declines with age. Research has investigated whether epitalon may influence pineal function and melatonin production pathways in animal models, making it relevant to circadian biology and aging research.</p><h2>Published Research Scope</h2><p>Khavinson and colleagues have published extensively on epitalon, primarily in Russian biogerontology literature and international journals. Key research areas include:</p><ul><li>Telomerase activation in human cell culture studies</li><li>Lifespan extension studies in fruit fly and rodent models</li><li>Antioxidant activity in in-vitro models</li><li>Oncostatic effects in some animal tumor models (reduced incidence observed)</li><li>Melatonin and circadian pathway interactions in animal studies</li></ul><h2>Frequently Asked Questions</h2><p>Q: What is the evidence for epitalon's telomerase effects?</p><p>A: The primary evidence comes from in-vitro studies in human fetal fibroblasts published by Khavinson et al. (2003), which demonstrated increased telomerase activity and elongated proliferative capacity. Independent replication in larger study series is an ongoing area of research.</p><p>Q: Is epitalon the same as epithalamin?</p><p>A: No. Epithalamin is a polypeptide extract from the bovine pineal gland. Epitalon is a synthetic tetrapeptide analog (Ala-Glu-Asp-Gly) designed to replicate key biological activities attributed to epithalamin.</p><p>Q: What purity is appropriate for epitalon research?</p><p>A: ≥99% HPLC purity with LC-MS identity confirmation.
