N-Acetyl Epitalon Amidate 5mg
N-Acetyl Epitalon Amidate
Ac-Ala-Glu-Asp-Gly-NH2
Overview
N-Acetyl Epitalon Amidate is a structurally modified version of epitalon (Ala-Glu-Asp-Gly) featuring two chemical modifications: N-terminal acetylation and C-terminal amidation. These modifications are standard pharmaceutical chemistry techniques used to improve peptide stability and bioavailability. The N-terminal acetylation (addition of an acetyl group to the amino terminus) protects the peptide from aminopeptidases — enzymes that degrade peptides by cleaving amino acids from the N-terminus. The C-terminal amidation (replacing the carboxylic acid with an amide group) protects against carboxypeptidases and also mimics the natural C-terminal structure of many bioactive peptides, potentially improving receptor binding. The underlying biological activity is expected to mirror that of unmodified epitalon — telomerase activation, melatonin production enhancement, and potential geroprotective effects as characterized by Khavinson and colleagues. However, the structural modifications may improve cellular uptake, extend circulating half-life, and enhance overall potency on a per-mole basis. Direct comparative studies between the modified and unmodified forms are limited in the published literature, so the degree of bioavailability improvement remains a subject of ongoing research.

Key Research Findings
- Khavinson et al. (2003) demonstrated the parent compound epitalon activates telomerase and elongates telomeres in human somatic cells.
- Werle & Bernkop-Schnurch (2006) reviewed N-terminal and C-terminal peptide modifications for improved metabolic stability, the chemical basis for N-acetyl amidation.
- Anisimov et al. (2003) showed epitalon extends lifespan and inhibits tumor development in mice, effects that the modified form aims to enhance.

Dosage in Research
Due to potentially improved bioavailability, lower doses may be effective compared to unmodified epitalon. Direct dosing comparisons are not yet established in the literature.
