Selank is a synthetic heptapeptide developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. It is an analogue of the endogenous tetrapeptide tuftsin, with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. The addition of the Pro-Gly-Pro sequence to the parent tuftsin structure significantly enhances its metabolic stability and duration of action in preclinical research settings.
Researchers have studied Selank for its potential interactions with the GABAergic and serotonergic neurotransmitter systems. In preclinical models, studies have examined its effects on anxiety-related behaviors, suggesting possible anxiolytic properties through mechanisms distinct from classical benzodiazepines. Research has also explored its influence on expression of BDNF (brain-derived neurotrophic factor) and other neurotrophic markers in animal brain tissue.
Laboratory studies have investigated Selank’s potential immunomodulatory properties, reflecting its structural relationship to tuftsin, which is known to regulate macrophage and immune cell function. Research has also examined its effects on enkephalin metabolism and cognitive performance metrics in animal models. Its multi-target pharmacological profile has made it a compound of ongoing interest in neuropeptide research.
