This review discusses the properties of Epitalon, a tetrapeptide composed of Ala-Glu-Asp-Gly (AEDG), synthesized from bovine pineal gland extract. It highlights findings from 25 years of research, including its antioxidant and neuroprotective effects, but does not provide specific numeric outcomes from clinical studies. The review aims to summarize the current knowledge on Epitalon.
Abstract
Epitalon, also known as Epithalon or Epithalone, is a tetrapeptide, Ala-Glu-Asp-Gly (AEDG), which was synthesized based on the amino acids composition of Epithalamin, a bovine pineal gland extract, prior to its discovery in pineal gland polypeptide complex solution. During the last 25 years, this compound has been extensively studied using in vitro, in vivo, and in silico methods. The results of these studies indicate significant geroprotective and neuroendocrine effects of Epitalone, resulting from its antioxidant, neuro-protective, and antimutagenic effects, originating from both specific and nonspecific mechanisms. Although it has been demonstrated that Epitalon exerts, among other effects, a direct influence on melatonin synthesis, alters the mRNA levels of interleukin-2, modulates the mitogenic activity of murine thymocytes, and enhances the activity of various enzymes, including AChE, BuChE, and telomerase, it remains uncertain whether these are the sole mechanisms of action of this compound. Moreover, despite the considerable volume of research on the biological and pharmacodynamic characteristics of Epitalon, the quantity of physico-chemical and structural investigations of this peptide remains quite limited. This review aims to conclude the most important findings from such studies, thus presenting the current state of knowledge on Epitalon.
Background
Epitalon is a tetrapeptide derived from the pineal gland, previously studied for its potential effects on aging and various biological processes. Prior research has indicated various bioactive properties of peptides, but the specific mechanisms and clinical relevance of Epitalon remain under investigation. This study aims to synthesize existing knowledge about Epitalon and its purported benefits.
