Compound Overview
What Is Epithalon?
Epithalon (also written Epitalon) is a synthetic tetrapeptide composed of four amino acid residues in the sequence Alanine-Glutamic acid-Aspartic acid-Glycine — abbreviated Ala-Glu-Asp-Gly. It carries the molecular formula C₁₄H₂₂N₄O₉ with a molecular weight of approximately 390 Da and is catalogued under CAS number 307297-39-8.
The peptide was developed as a synthetic analog of epithalamin, a polypeptide fraction originally isolated from bovine pineal gland tissue. The isolation and characterization of epithalamin, and the subsequent synthesis of Epithalon as a defined four-amino-acid unit, were performed at the St. Petersburg Institute of Bioregulation and Gerontology.
Within the peptide research classification system, Epithalon belongs to the category of pineal peptide bioregulators — short-chain peptides whose research interest centers on their interaction with pineal gland-associated signaling pathways. Published research has investigated it primarily in cell culture and preclinical animal model contexts. It is classified as a research compound and is not approved for human use.
Prof. Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology (Russia) have published extensively on pineal-derived peptide bioregulators beginning in the 1970s. Their body of work introduced the concept of short peptide bioregulation — the hypothesis that di- and tetrapeptide sequences derived from tissue extracts could influence cell-type-specific gene expression in preclinical models.
Epithalon emerged from this research program as the synthetic equivalent of the active fraction of epithalamin. Published research from this group and independent laboratories has since examined Epithalon in cell cycle, telomerase pathway, circadian rhythm, and oxidative stress contexts using in vitro and animal models. All research classification applies: findings do not establish conclusions regarding human biology.
Research Classification: Epithalon is a research sample for in vitro and preclinical study only. It is not a pharmaceutical, not a dietary supplement, and is not intended for human or veterinary use. For research use only.
Published Research Areas
Research Background
The following five research areas represent domains in which published preclinical literature has examined Epithalon. All work cited applies to in vitro and animal model contexts. No conclusions regarding human physiology are intended or implied.
Published research has examined Epithalon's effect on telomerase enzyme activity in somatic cell culture models. Preclinical research has investigated whether Epithalon influences the expression of telomerase reverse transcriptase (TERT) in proliferating human cell lines. Findings are from in vitro studies only.
In Vitro · Cell LinesAs a synthetic analog of the natural pineal extract epithalamin, Epithalon is a primary subject of pineal peptide bioregulation research. Published research has examined its interaction with gene expression profiles in cell models, representing part of a broader body of work on short-chain peptide bioregulators originating from pineal tissue research.
Bioregulation · Pineal ResearchGiven its pineal gland research origins, published preclinical research has investigated Epithalon in animal models examining circadian rhythm-associated endpoints. Research has explored its relationship to melatonin pathway markers in rodent models. These findings are preclinical and cannot be extrapolated to human circadian biology.
Animal Models · CircadianPreclinical research has investigated Epithalon's influence on cell cycle progression and proliferation markers in cell culture systems. Published research has examined its effects on cell division parameters and proliferative indices across various cell line types. All findings originate from in vitro experimental settings.
In Vitro · Cell CyclePublished research has examined Epithalon in preclinical animal models assessing markers associated with oxidative stress pathways, including antioxidant enzyme activity and lipid peroxidation indices. These are animal model findings and do not constitute evidence of equivalent effects in human biology.

Reconstitution Reference
The following is provided as general laboratory reference for researchers working with lyophilized peptide research samples. All handling should conform to applicable laboratory safety protocols. For research use only — not for human use.
Bacteriostatic water (0.9% benzyl alcohol) is standard for lyophilized peptide research samples. Sterile water for injection may also be appropriate depending on intended research application. Allow solvent to reach ambient temperature before use.
Using appropriate sterile technique, introduce solvent slowly along the inner wall of the vial — directing the solvent stream at the glass, not directly at the lyophilized cake. Standard research practice for a 10mg research sample is to introduce 1–2mL solvent volume, yielding a 5–10mg/mL research solution.
Allow the lyophilized material to dissolve without mechanical agitation. Gentle swirling may assist dissolution. Do not vortex or shake. Epithalon is water-soluble and typically dissolves completely within a few minutes at ambient temperature.
Store the reconstituted research solution at 2–8°C (refrigerated). Protect from light. Use within 28 days for in vitro research purposes, or as appropriate per the specific research protocol. Lyophilized (unreconstituted) research samples should be stored at −20°C.
