Selank: Selank (Anxiolytic Heptapeptide)
Category: Cognitive & Neurological
Selank is a synthetic analog of the naturally occurring immunomodulatory peptide tuftsin, with an additional sequence that provides enhanced stability and neurological activity. Like Semax, it was developed at the Institute of Molecular Genetics in Russia and has been approved as a prescription medication in Russia for anxiety and related disorders.
This guide compiles key literature themes, handling context, and practical comparison points for research-focused evaluation.
Overview
The peptide's mechanism centers on GABA system modulation, producing anxiolytic effects that researchers have compared to benzodiazepines but without the sedation, cognitive impairment, or dependence potential. This clean anxiolytic profile has generated significant research interest internationally.
Discovery & Background
Selank was developed through the 1990s and 2000s by researchers at the Russian Academy of Sciences, building on earlier work with the immunopeptide tuftsin. The goal was to create a compound with anxiolytic properties that lacked the drawbacks of existing medications. After extensive preclinical work, it received regulatory approval in Russia and has been available as a nasal spray since the early 2010s.
Mechanism of Action
Selank modulates the GABAergic system and influences serotonin metabolism, producing anxiolytic effects without sedation or dependency. It also has immunomodulatory properties inherited from its tuftsin parent molecule.
- 1Modulates GABA receptor activity, enhancing inhibitory signaling in anxiety-related circuits
- 2Increases BDNF expression, though to a lesser degree than Semax
- 3Influences serotonin metabolism and 5-HT receptor sensitivity
- 4Stabilizes enkephalin degradation, prolonging the activity of natural anti-anxiety peptides
- 5Retains immunomodulatory properties from its tuftsin base, influencing cytokine balance
- 6Does not produce tolerance, dependence, or withdrawal in published studies
Research Benefits
The benefit areas below reflect commonly discussed research interests for this peptide.
Anxiolytic Effects
Reduces anxiety-like behavior in animal models with potency comparable to benzodiazepines, but without sedation or dependency.
Cognitive Support
Studies show improvements in learning and memory alongside anxiety reduction, a combination not typical of traditional anxiolytics.
Immunomodulation
Modulates immune function through its tuftsin-derived structure, potentially useful in psychoneuroimmunology research.
No Dependency
Published research shows no tolerance development, physical dependence, or withdrawal effects with sustained use.
Published Research
Anxiolytic Activity
Selank showed anxiolytic effects comparable to phenazepam (a benzodiazepine) in elevated plus maze testing without affecting motor coordination.
Bulletin of Experimental Biology and Medicine, 2008
Gene Expression
Selank influenced expression of 36 genes related to GABAergic signaling, serotonin receptors, and immune function in the hippocampus.
BMC Neuroscience, 2009
Cognitive Effects
Improved learning performance in rats under stress conditions, suggesting both anxiolytic and nootropic effects.
Behavioural Brain Research, 2010
Immune Function
Modulated IL-6, IL-10, and TNF-alpha levels, demonstrating significant immunomodulatory activity.
Immunology Letters, 2012

Frequently Asked Questions
What is Selank?
Selank is a synthetic heptapeptide based on the natural immunopeptide tuftsin with an added Pro-Gly-Pro sequence. It was developed in Russia as an anxiolytic without the drawbacks of benzodiazepines.
How does Selank reduce anxiety?
Selank modulates the GABA system and stabilizes enkephalins, the body's natural anti-anxiety peptides. Unlike benzodiazepines, it does not cause sedation, cognitive impairment, or physical dependence.
Can Selank and Semax be studied together?
Yes. Some researchers study them in combination because they have complementary mechanisms. Semax primarily enhances cognition through BDNF, while Selank targets anxiety through GABA modulation.
What is tuftsin?
Tuftsin is a naturally occurring tetrapeptide (Thr-Lys-Pro-Arg) involved in immune function. It stimulates phagocytosis and immune cell activity. Selank was built on the tuftsin backbone with additional amino acids.
How is Selank administered in research?
Like Semax, Selank is typically administered intranasally in published studies. This route provides rapid absorption and good bioavailability for CNS research.
