Epithalon

Description

Synthetic tetrapeptide for telomerase activation and longevity research.

Epithalon (also known as Epitalon or epithalamin) is a synthetic tetrapeptide (Ala-Glu-Asp-Gly) developed by Vladimir Khavinson at the Saint Petersburg Institute of Bioregulation and Gerontology in Russia. Its primary mechanism of action involves activation of telomerase, the enzyme responsible for adding telomeric repeats (TTAGGG) to chromosome ends, thereby counteracting the progressive telomere shortening associated with cellular aging. Published research by Khavinson and colleagues (Bulletin of Experimental Biology and Medicine, 2003) demonstrated that epithalon increased telomerase activity in human somatic cells and extended the replicative lifespan of fibroblast cultures beyond the Hayflick limit. In animal studies, chronic epithalon administration in aging rats was associated with increased lifespan and restoration of melatonin secretion rhythms from the pineal gland, which naturally declines with age (Anisimov et al., Mechanisms of Ageing and Development, 2003). The peptide also appears to modulate expression of genes involved in antioxidant defense and circadian rhythm regulation. Compared to other telomerase activators such as TA-65 (a small molecule derived from astragalus), epithalon is a direct peptide bioregulator with a well-characterized tetrapeptide sequence. Research also suggests potential effects on retinal health, with studies indicating photoreceptor preservation in aging retinal models. Store lyophilized powder at -20C protected from moisture; reconstitute with bacteriostatic water and refrigerate at 2-8C for up to 21 days. Epithalon is studied by gerontology research centers, telomere biology laboratories, and chronobiology departments investigating age-related decline in pineal gland function.
