Epithalon

Epithalon, also spelled Epitalon, is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly derived from work on pineal bioregulators and biological aging. Research has focused on the compound as a short peptide signal linked to telomere biology, chromatin regulation, and age-associated changes in cell-cycle control. Mechanistic studies suggest Epithalon can increase telomerase activity, alter hTERT expression, and shift transcriptional programs connected to DNA maintenance and cellular senescence. Research also discusses effects on pineal signaling and oxidative-stress markers in aging models. Preclinical and cell-culture findings show repeated investigation of telomere length, replicative lifespan, tumor incidence, and age-related physiologic markers. The evidence base is stronger in animal and cell systems than in large independently replicated human datasets. Epithalon remains a research compound with substantial interest but limited Western clinical validation. Its main value at present is as a probe for aging-associated signaling rather than a settled intervention. References: [1] Khavinson VK, Bondarev IE, Butyugov AA. (2003).
