Epitalon (also spelled Epithalon) is a synthetic tetrapeptide consisting of four amino acids: alanine, glutamic acid, aspartic acid, and glycine. It was originally synthesized based on research into endogenous peptide bioregulators produced by the pineal gland, specifically as a synthetic analog of the naturally occurring epithalamin complex. Preclinical experimental research has examined Epitalon in the context of telomerase activity modulation, melatonin-associated signaling, and cellular replication dynamics. In-vitro studies have reported observations related to telomerase activation in human somatic cell cultures, with researchers using the peptide as a molecular tool to investigate telomere length maintenance and cellular senescence pathways. Additional laboratory investigations have referenced Epitalon in studies examining circadian rhythm markers, neuroendocrine regulation, and oxidative stress response in animal models. Published preclinical findings describe associations with antioxidant enzyme activity and age-related physiological markers under controlled experimental conditions.
