Epitalon (also written Epithalon or Epithalone) is the most widely studied of the bioregulator peptides. This overview covers its structure, the research context it is best known for, and how it fits within the wider Khavinson peptide family.
Structure
Epitalon is a short synthetic tetrapeptide — a chain of just four amino acids (Ala-Glu-Asp-Gly). It was developed as a synthetic analogue of a naturally occurring peptide complex studied in association with the pineal gland.
Pineal research context
Much of the interest in Epitalon stems from research into the pineal system. In the scientific literature it is frequently examined in the context of pineal signalling and circadian-related pathways, which is why it is categorised among the tissue-specific bioregulators.
The telomere and telomerase studies
Epitalon is perhaps best known in research circles for studies exploring telomeres — the protective caps at the ends of chromosomes — and the enzyme telomerase. This body of pre-clinical and cell-culture work is what gives Epitalon its prominent profile within longevity-focused research literature. It is important to note this remains a research context only.
How it relates to the wider bioregulator range
Epitalon sits alongside other Khavinson peptides such as Cortagen, Cartalax and Crystagen. What unites them is the underlying bioregulator concept: short peptide sequences studied in relation to specific tissues and systems. For a broader introduction, see our guide to the Khavinson bioregulator range.
Handling and storage
Epitalon is typically supplied lyophilised. As with other research peptides, it should be protected from heat, light and moisture, and stored cold until reconstitution.
Summary
Epitalon is a four-amino-acid bioregulator peptide best known for pineal-system and telomere-related research. Its compact structure and prominent place in the literature make it a common starting point for those exploring the bioregulator category.
