The Dossier

Research Notes

Selank is a synthetic heptapeptide derived from the endogenous tetrapeptide tuftsin — a natural fragment of immunoglobulin G — extended with a Pro-Gly-Pro tail for enhanced metabolic stability. It was developed at the Russian Academy of Sciences and is noted for high intranasal bioavailability.

It is a defining reference within cognitive research, characterized for its stability and neurochemical-signaling profile.

Research Focus

  • Anxiety and neurasthenia models
  • Nootropic and memory-trace paradigms
  • Alcohol- and opioid-withdrawal models
  • Immunomodulation and antiviral research
  • Transcriptome-modulation studies

Mechanism

Selank is characterized as a positive allosteric modulator of the GABA-A receptor at a site distinct from the classical benzodiazepine site, together with inhibition of enkephalin-degrading enzymes that extends enkephalin signaling.

It has been reported to alter GABA-receptor subunit expression and elevate BDNF/TrkB signaling, modulating serotonin, norepinephrine, and dopamine region-specifically.
