Description

N-Acetyl Selank Amidate is a terminally modified analog of Selank — the tuftsin-derived heptapeptide studied for GABAergic signaling and neuroimmune interaction in nootropic peptide CNS research. N-terminal acetylation and C-terminal amidation are added to the core Thr-Lys-Pro-Arg-Pro-Gly-Pro sequence, protecting both termini from aminopeptidase and carboxypeptidase-mediated degradation. The tuftsin-analog sequence and the GABAergic inhibitory and neuroimmune signaling research context it carries are unchanged — the modification addresses the pharmacokinetic limitation of rapid proteolytic clearance that constrains unmodified Selank in longer-duration experimental protocols.

Chemical Information

  • Chemical Name: N-Acetyl Selank Amidate (N-acetylated, C-terminally amidated analog of Selank)
  • Also Known As: Ac-Selank-NH2; acetylated Selank amide
  • Compound Class: Modified synthetic heptapeptide analog; stability-enhanced derivative of Selank, an anxiolytic-profile analog of the immunomodulatory tetrapeptide tuftsin
  • Sequence: N-acetyl-Thr-Lys-Pro-Arg-Pro-Gly-Pro-amide (N-terminal acetylation and C-terminal amidation of the parent Selank sequence)
  • Molecular Formula: Not established in public literature for the modified analog (parent Selank: C33H57N11O9)
  • Molecular Weight: Not established in public literature for the modified analog (parent Selank: 751.87 g/mol)
  • CAS Number: Not established in public literature for the modified analog (parent Selank: 129954-34-3)

Applications

  • Peptide stability and pharmacokinetic modification research. N-terminal acetylation and C-terminal amidation are standard modifications that reduce degradation by aminopeptidases and carboxypeptidases. Therefore, researchers use this analog alongside unmodified Selank to study how these terminal modifications affect proteolytic resistance and duration of activity in cell-based and animal assays
  • Anxiolytic and stress-response signaling research. Because the modified analog retains Selank’s core heptapeptide sequence, it is studied within the same research framework as the parent compound, which has been examined for effects on GABAergic signaling, BDNF expression, and stress-related behavior in animal models
  • Comparative structure-activity research alongside unmodified Selank. Researchers use N-Acetyl Selank Amidate and unmodified Selank side by side to assess whether terminal modification changes receptor engagement, degradation kinetics, or downstream signaling outcomes

Storage and Handling

Store lyophilized powder at -20C for long-term stability, or at 2-8C for short-term use. Protect from heat, moisture, and direct light. Reconstitute with an appropriate aqueous buffer immediately before use; store reconstituted solution at 2-8C and avoid repeated freeze-thaw cycles.

Frequently Asked Questions

What is N-Acetyl Selank Amidate?

N-Acetyl Selank Amidate is a terminally modified form of Selank with N-terminal acetylation and C-terminal amidation. These modifications improve proteolytic stability by protecting the tuftsin-derived heptapeptide sequence at both termini. The core sequence and its GABAergic inhibitory signaling, serotonergic modulation, and neuroimmune interaction research context are unchanged from unmodified Selank.

When should a researcher use N-Acetyl Selank Amidate instead of unmodified Selank?

Unmodified Selank has a stronger published literature base and is the appropriate choice for replicating established research designs. N-Acetyl Selank Amidate is appropriate when the protocol requires longer compound persistence in biological systems — particularly in multi-hour CNS exposure studies. Or when the research question involves directly comparing the behavior of terminally modified vs unmodified Selank as a structure-activity variable. The modification is a pharmacokinetic tool, not a mechanistic one.

How does N-Acetyl Selank Amidate relate to N-Acetyl Semax Amidate in combined CNS research?

The same complementary-pathway logic that makes unmodified Semax and Selank useful in parallel CNS research applies to their modified analogs. N-Acetyl Semax Amidate addresses the neurotrophic signaling axis through ACTH-derived BDNF pathway interaction. On the other hand, N-Acetyl Selank Amidate addresses the inhibitory signaling axis through tuftsin-analog GABAergic interaction. Using both modified forms in combined protocols provides the same mechanistic complementarity as the unmodified pair, with improved persistence for longer-duration experimental designs.
