What Is Epitalon?
Epitalon (also spelled Epithalon) is a synthetic tetrapeptide with the sequence Ala-Glu-Asp-Gly. It was developed based on research into epithalamin, a peptide extract from the pineal gland. Epitalon has become one of the most studied peptides in telomerase and longevity research, attracting significant interest from the preclinical research community.
With a molecular weight of approximately 390.35 Da, Epitalon is one of the smallest peptides actively used in aging research models.
Telomerase Activation Research
Telomere Biology Background
Telomeres are protective nucleoprotein structures at chromosome ends that shorten with each cell division in laboratory models. Telomerase is the enzyme responsible for maintaining telomere length. The relationship between telomere length and cellular senescence has been a central focus of aging research.
Epitalon & Telomerase Studies
Preclinical research has investigated Epitalon’s potential to activate telomerase in cell culture models. In-vitro studies have demonstrated that Epitalon treatment may be associated with increased telomerase reverse transcriptase (hTERT) expression in certain cell lines. These findings have positioned Epitalon as a key research tool in telomere biology.
Pineal Gland Research
Melatonin Pathway Studies
Research has explored Epitalon’s interactions with pineal gland function in preclinical models. Laboratory studies have investigated its potential effects on melatonin synthesis pathways, as the original epithalamin compound was derived from pineal extracts.
Circadian Rhythm Research
In-vitro and preclinical studies have examined Epitalon’s potential role in circadian rhythm-related research. The connection between pineal function and circadian biology has made this an area of active investigation.
Longevity Research Applications
Epitalon is frequently studied alongside other longevity-focused compounds:
- NAD+ — cellular energy and sirtuin research
- FOXO4-DRI — senolytic peptide research
- MOTS-c — mitochondrial-derived peptide studies
The N-Acetyl Epitalon Amidate variant offers a modified form with enhanced stability characteristics for certain research protocols.
Antioxidant Research
Laboratory studies have also examined Epitalon’s potential antioxidant properties. In-vitro oxidative stress models have been used to investigate the peptide’s effects on reactive oxygen species (ROS) levels and antioxidant enzyme expression in cell culture systems.
Research Considerations
- Store lyophilized at -20°C
- Reconstitute with sterile water or bacteriostatic water
- Available in 10mg and 50mg preparations
- Verify purity ≥98% via HPLC before experimental use
Conclusion
Epitalon continues to be a focal point of telomerase and longevity research. Its well-characterized tetrapeptide structure, combined with a growing preclinical literature base, makes it an essential compound for researchers investigating telomere biology and cellular aging. Molecular Peptides provides Epitalon with comprehensive third-party analytical documentation.
