What is Selank?

Selank is a synthetic peptide developed by Russian researchers as an analog of the naturally occurring tuftsin molecule. This heptapeptide has been studied for its potential anxiolytic and nootropic effects in animal models. Research suggests Selank may influence neurotransmitter systems, particularly GABA, serotonin and dopamine pathways. Some studies indicate it could affect memory formation, stress responses, and cognitive function.

Anxiolytic Effects

Selank peptide has been extensively studied for its anxiolytic properties, demonstrating significant potential in reducing anxiety levels. Clinical trials have shown that Selank can effectively alleviate symptoms of generalized anxiety disorder (GAD) and neurasthenia, with efficacy comparable to benzodiazepine treatments. Selank has also been found to inhibit enkephalin-degrading enzymes, which may contribute to its anxiolytic activity [R, R].

Memory and Learning Processes

Research has highlighted Selank’s ability to improve cognitive function, particularly in memory consolidation and learning processes. Studies indicate that Selank improves memory storage processes and increases the stability of memory traces for an extended period. This suggests that the peptide may have long-lasting effects on memory consolidation and retention [R].

Additionally, Selank has shown promise in restoring cognitive processes that have been impaired due to damage to the cerebral catecholamine system [R].

Immunomodulatory Effects

Selank demonstrated notable immunomodulatory effects in patients with anxiety-asthenic disorders. The research revealed that Selank had a significant impact on interleukin-6 (IL-6), a key cytokine involved in immune responses.

Research found that Selank altered the balance between T helper 1 (Th1) and T helper 2 (Th2) cytokines in vivo. This shift in the Th1/Th2 cytokine ratio suggests that Selank may influence the overall immune response by modulating the activity of different T helper cell subsets [R].


Selank administration led to significant changes in the mRNA levels of 45 genes related to neurotransmission, similar to the effects observed with GABA administration. This suggests that Selank may act through allosteric modulation of GABA receptors, altering their affinity for GABA and affecting neurotransmission. Selank’s impact on gene expression was not limited to the GABAergic system; it also affected genes related to dopamine and serotonin systems, indicating a broader neuroprotective role [R].


What are the Effects of Selank on Serotonin?

Some evidence points to Selank’s ability to affect serotonin metabolism. Serotonin is a neurotransmitter often associated with feelings of well-being and happiness. Selank modulates both dopamine and serotonin receptors [R].

Is Selank a Nootropic?

Selank is considered a nootropic peptide with anxiolytic (anti-anxiety) properties. Selank has demonstrated nootropic (cognitive-enhancing) effects in studies, including improvements in memory consolidation and learning processes. Selank appears to modulate neurotransmitter systems, including serotonin metabolism, and increase brain-derived neurotrophic factor (BDNF) expression in the hippocampus.

Which Other Peptides Have Been Researched for Anxiety?

Other research peptides studied for their potential axiolytic effects include Bromantane, BPC-157, and Cerebrolysin.
