Selank: Tuftsin-Derived Heptapeptide Research Peptide
Selank is a synthetic heptapeptide derived from the immunomodulator tuftsin, originally developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. Its Pro-Gly-Pro C-terminus extends in-vivo half-life and enables stable intranasal bioavailability in preclinical models, which has made it a workhorse of cognitive and stress-response peptide research for more than two decades.
Mechanism of Action
Preclinical studies show Selank modulates expression of brain-derived neurotrophic factor (BDNF), influences monoamine neurotransmitter tone (serotonin, dopamine, norepinephrine), and produces measurable shifts in hippocampal gene expression related to neuroplasticity. Unlike benzodiazepines, Selank does not directly bind GABA-A receptors; it modulates GABAergic activity indirectly through enkephalin and monoaminergic pathways, which is the dominant hypothesis for its non-sedating stress-response profile in animal models.
