N-Acetyl Selank Amidate Description
Selank is a heptapeptide (Thr-Lys-Pro-Arg-Pro-Gly-Pro) with significant anxiolytic, cognitive-enhancing, and immunomodulatory effects. Its ability to modulate the GABAergic system and influence gene expression underlies its therapeutic research potential, particularly in managing anxiety and stress-related conditions.
N-Acetyl Selank is a modified version of Selank designed to improve its pharmacological properties. The addition of an acetyl group at the N-terminus enhances its stability, potency, and ability to cross the blood-brain barrier.

N-Acetyl Selank Research
Selank is a multifaceted peptide with significant potential in treating anxiety, cognitive impairments, and stress-related physiological changes. Its ability to modulate the GABAergic system, enhance cognitive function, and exert immunomodulatory effects positions it as a versatile therapeutic agent.
Anxiolytic and Cognitive Effects
Selank has demonstrated significant anxiolytic properties, comparable to classical benzodiazepines, without the associated side effects such as dependence and memory impairment1. It has been shown to reduce anxiety in conditions of chronic stress and improve cognitive functions, such as memory and attention, particularly in the context of ethanol-induced impairments. The peptide’s ability to regulate brain-derived neurotrophic factor (BDNF) content in the hippocampus and prefrontal cortex is thought to contribute to its cognitive-enhancing effects2.
Immunomodulatory and Antiviral Properties
Beyond its neurological effects, Selank also exhibits immunomodulatory and antiviral properties. It can significantly alter the expression of genes related to chemokines, cytokines, and their receptors, suggesting a role in immune response modulation3. These properties make Selank a promising candidate for therapeutic applications beyond anxiety and cognitive disorders.
Stress Mitigation and Physiological Effects
Selank has been shown to mitigate stress-induced physiological changes. In animal models, it reduces stress-related morphological changes in organs such as the liver and colon, indicating its potential to alleviate stress-induced damage. These effects are likely due to its multifunctional biological activity, which includes reducing corticosterone levels and promoting adaptation to stress4.
