How is N-Acetyl Selank Amidate different from regular Selank?

The acetyl and amide modifications make the molecule more resistant to enzymatic breakdown, giving it a longer duration of action and better suitability for intranasal delivery than unmodified Selank.

Is Selank addictive like benzodiazepines?

Research describes Selank analogs as anxiolytic without the sedation, tolerance, or dependence associated with benzodiazepines, which is a major reason it is studied as an alternative.

Why is it taken intranasally?

Intranasal delivery provides direct access to the central nervous system and bypasses the rapid degradation peptides face in the digestive tract.

N-Acetyl Selank Amidate

Also known as: N-Acetyl Selank Amidate, N-Acetyl Selank

N-Acetyl Selank Amidate is a stabilized analog of the anxiolytic peptide Selank, modified for improved durability and intranasal delivery. It is studied for anxiety reduction and cognitive support.

Mechanism of Action

N-Acetyl Selank Amidate is a Tuftsin-derived heptapeptide analog in which N-terminal acetylation and C-terminal amidation increase resistance to enzymatic degradation. It modulates the GABAergic and serotonergic systems and influences the expression and metabolism of enkephalins, producing anxiolytic effects without sedation or dependence. Selank analogs also raise brain-derived neurotrophic factor (BDNF) and modulate the balance of pro- and anti-inflammatory cytokines, linking its nootropic and immune-modulating actions. The stabilizing modifications support its use via intranasal administration for central nervous system access.
