Description
Epithalon (also spelled Epitalon) is a synthetic tetrapeptide bioregulator with the amino acid sequence Ala-Glu-Asp-Gly (AEDG), developed by Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology. The peptide was originally derived from the protein structure of Epithalamin, a pineal gland extract studied extensively in Russian gerontology research since the 1960s. Epithalon is investigated as a Khavinson-class short peptide with proposed epigenetic regulatory activity, including studies reporting telomerase reactivation, telomere elongation in cell-culture models, and modulation of melatonin and serotonin biosynthesis in the pineal gland. Research interest extends to circadian rhythm regulation, age-associated gene expression patterns, antioxidant defense pathways, and longevity-related endpoints in rodent and human aging studies. Its small molecular weight (~390 Da) supports cellular uptake and is reported to enable direct DNA / chromatin interaction at gene promoter regions, consistent with the broader Khavinson bioregulator hypothesis.
