Overview

N-Acetyl Epitalon Amidate is a stability-optimized variant of the longevity tetrapeptide Epithalon (Epitalon), incorporating both N-terminal acetylation and C-terminal amidation. These modifications enhance resistance to exopeptidase degradation, potentially improving systemic bioavailability and duration of action for telomerase activation research.

The parent compound Epithalon has demonstrated telomerase-activating properties in research settings, with implications for telomere maintenance and cellular longevity. It also influences pineal gland function and melatonin synthesis, contributing to circadian rhythm regulation and antioxidant support.

The minimal tetrapeptide structure of Epithalon makes it particularly susceptible to rapid enzymatic degradation following systemic administration. The dual terminal modifications in this variant address this vulnerability while preserving the core sequence believed responsible for biological activity through DNA interaction and gene expression modulation.

N-Acetyl Epitalon Amidate is of interest for research applications requiring sustained exposure to the telomerase-activating peptide, including long-term studies of cellular senescence, tissue regeneration, and comprehensive anti-aging protocols. The enhanced stability may enable lower dosing frequencies while maintaining research endpoints.

Synthesis Overview

N-Acetyl Epitalon Amidate is synthesized via Fmoc solid-phase peptide synthesis on Rink amide resin to generate the C-terminal amide. Following assembly of the short tetrapeptide sequence (Ala-Glu-Asp-Gly), the N-terminus is acetylated on-resin using acetic anhydride. TFA cleavage with triisopropylsilane scavenger yields the doubly-modified peptide. The short sequence allows high synthesis yields and straightforward purification via preparative HPLC. Both terminal modifications are confirmed by mass spectrometry.
