Epithalon

Origin & Classification

Epithalon, also known as epitalon, is a synthetic tetrapeptide composed of alanine-glutamic acid-aspartic acid-glycine (Ala-Glu-Asp-Gly). It is modeled on a naturally occurring peptide isolated from bovine pineal gland extracts, often referred to as epithalamin. As a short chain of four amino acids, Epithalon falls within the class of bioactive tetrapeptides and is produced via solid-phase peptide synthesis, ensuring high purity and sequence fidelity.

Mechanism & Research Context

Epithalon has drawn scientific interest for its role in regulating telomerase activity and circadian rhythms. In cellular systems, it has been reported to influence telomerase reverse transcriptase expression, thereby potentially affecting telomere maintenance and chromosomal stability. Researchers also investigate Epithalon in the context of melatonin secretion and pineal gland signaling, examining how the peptide may modulate endocrine axes such as hypothalamic-pituitary-gonadal and hypothalamic-pituitary-adrenal pathways. Studies often assess downstream signaling cascades including MAPK/ERK, p53/p21, and reactive oxygen species regulation, with a focus on understanding cellular senescence, DNA repair, and mitochondrial function. In circadian biology, Epithalon is used to explore the synchronization of peripheral clocks and the regulation of clock gene expression across tissues.

Composition & Quality

Epithalon is supplied as a lyophilized powder with purity commonly exceeding 96 % as measured by analytical HPLC. The peptide is synthesized under GMP-aligned conditions, with each batch subjected to mass spectrometric verification, amino acid analysis, and sterility testing. Because of its short length, Epithalon is highly soluble in water and stable under refrigeration when stored desiccated. Certificates of analysis accompany each lot, detailing peptide identity, purity, and recommended storage conditions.
