Selank

What is Selank?

Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic analog of tuftsin, a natural peptide known for its immune-supporting properties. In preclinical studies, Selank has demonstrated the ability to influence neurotransmitter balance, particularly in the GABAergic and serotonergic systems, and to enhance mental performance. These properties have made it a focus in research exploring anxiety, depression, and cognitive function [2].

Molecular Formula and Structure

• Molecular Formula: C₃₃H₅₇N₁₁O₉
• Molecular Weight: 751.9 g/mol

Selank’s structure features a stable heptapeptide chain that enhances its resistance to enzymatic degradation, supporting its prolonged activity in research models [3].

Selank Research

1. Anxiolytic Properties

Selank has been shown to produce significant anxiolytic effects in rodent models, comparable to classical benzodiazepines but without the sedative or dependence-inducing side effects. These studies indicate that Selank may act through modulation of GABA receptors and neurotransmitter gene expression [4].

2. Cognitive Enhancement and Memory

In preclinical experiments, Selank administration led to enhanced learning capacity and improved memory retention in test subjects. These findings suggest a role in research related to cognitive deficits and neurodegeneration [5].

3. Neurotransmitter Modulation

Selank has been found to alter gene expression linked to neurotransmitter systems, particularly those related to GABA, dopamine, and serotonin signaling. These changes may underlie the peptide’s potential antidepressant and anti-anxiety properties in neurochemical models [2][6].

4. Immunomodulatory Effects

Because Selank is a tuftsin analog, it has been studied for its influence on cytokine balance and immune system activation. Research has shown that Selank may increase resistance to stress and improve immune regulation under chronic stress conditions [2].

5. Antidepressant-Like Effects

Selank may exert antidepressant effects by stabilizing monoamine levels, particularly serotonin and norepinephrine, in animal models. Its ability to influence mood-related gene networks makes it a candidate for further research in affective disorders [5][6].
