Selank Research Overview

Introduction

Selank is a synthetic heptapeptide derived from the sequence of human immunoglobulin G (IgG). Developed in Russia, it has been studied for its effects on anxiety, immune function, and cognitive processes in animal models.

Mechanism of Action

Anxiolytic Effects

Animal studies suggest Selank may produce anxiolytic effects without the sedation or dependence associated with benzodiazepines. The mechanism may involve modulation of GABAergic neurotransmission.

Immunomodulatory Effects

As a derivative of IgG, Selank has been studied for its effects on immune function, including influences on cytokine production and T-cell activity in animal models.

Enkephalin Degradation

Research indicates Selank may inhibit enzymes that degrade enkephalins (endogenous opioid peptides), potentially influencing pain and stress responses.

Current Research

Anxiety Research

Animal studies using elevated plus maze and open field tests have investigated Selank's anxiolytic properties.

Immune Research

Studies have explored Selank's effects on inflammatory cytokines, antibody production, and immune cell activity in animal models.

Cognitive Research

Some research has investigated Selank's effects on memory, learning, and attention in animal behavioural models.

Chemical Properties

  • **Sequence:** Thr-Lys-Pro-Arg-Pro-Gly-Pro (7 amino acids)
  • **Molecular formula:** C33H57N11O9
  • **Molecular weight:** 751.9 g/mol
  • **Origin:** Synthetic fragment of human IgG
  • Storage Considerations

  • Store lyophilised Selank at -20°C.
  • Protect from light and moisture.
  • Reconstituted solutions should be aliquoted and stored at -20°C.
  • Testing Methods

    Selank batches should be verified by:

  • RP-HPLC for purity (≥98% recommended)
  • Mass spectrometry for identity confirmation
  • Research Limitations

    Selank is supplied for in vitro laboratory research and animal model studies only. Most published research originates from Russian research groups. No clinical trials outside Russia have confirmed efficacy. No medical, therapeutic, or dosing claims are made. Selank is not approved for human therapeutic use by Western regulatory authorities.
