Selank is a synthetic peptide, chemically described as Thr-Lys-Pro-Arg-Pro-Gly-Pro. It is structurally related to tuftsin, a naturally occurring immunomodulatory peptide found in the human body. Selank was developed in Russia and is primarily investigated for its potential anxiolytic (anti-anxiety) and nootropic (cognitive-enhancing) properties. Research suggests it may influence the concentrations of brain monoamines and expression of brain-derived neurotrophic factor (BDNF). While not widely available as a prescription medication in all countries, it has been studied clinically in regions like Russia for conditions involving anxiety and cognitive impairment (Source: PubChem, DrugBank). It is not currently approved by the U.S. Food and Drug Administration (FDA) for any medical use.
