Selank: The Anxiolytic Nootropic Peptide

Research on the tuftsin-derived peptide for anxiety and cognitive enhancement

Source: https://indexalabs.com/blog/selank-anxiolytic-nootropic-peptide Abstract: Selank is a synthetic peptide analog of the immune-modulating peptide tuftsin, developed in Russia for anxiolytic and nootropic applications. This guide covers its unique dual mechanism and research applications.

1. Introduction

Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a heptapeptide developed at the Institute of Molecular Genetics in Russia. It is based on tuftsin with additional amino acids that provide stability and enhanced neurotropic effects. Selank is approved in Russia as an anxiolytic.

2. Mechanisms of Action

2.1 GABA Modulation Selank enhances GABAergic transmission, producing anxiolytic effects without the sedation of benzodiazepines.

2.2 BDNF Expression Increases brain-derived neurotrophic factor, supporting neuroplasticity and cognitive function.

2.3 Serotonin Influence Modulates serotonergic neurotransmission, affecting mood and anxiety.

2.4 Enkephalin Stability Inhibits enkephalin-degrading enzymes, prolonging endogenous opioid signaling.

3. Research Applications

3.1 Anxiety Research Studies on generalized anxiety, social anxiety, and stress-related conditions.

3.2 Cognitive Enhancement Research on memory, learning, and attention under stress.

3.3 Immune Function The tuftsin backbone provides immunomodulatory effects alongside neurotropic actions.

3.4 Depression Research Investigation of mood-elevating effects through multiple neurotransmitter systems.

4. Research Protocols

4.1 Available Sizes Selank is available in 10mg vials.

4.2 Administration Routes Research has used both intranasal and subcutaneous administration.

4.3 No Dependence Unlike benzodiazepines, Selank does not appear to cause tolerance or dependence in research settings.
