N-Acetyl Selank Amidate (NA-Selank Amidate) is a terminally modified analogue of Selank. It retains the Selank core sequence while adding N-terminal acetylation and C-terminal amidation, producing the sequence Ac-Thr-Lys-Pro-Arg-Pro-Gly-Pro-NH₂ (Ac-TKPRPGP-NH₂). Research interest centres on stress and anxiety signalling, GABAergic neurotransmission, cognition and peptide stability.
