Selank (Russian: Cеланк) is a nootropic, anxiolyticpeptide based drug developed by the Institute of Molecular Genetics of the Russian Academy of Sciences. Selank is a heptapeptide with the sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP). It is a synthetic analogue of human tuftsin.
In clinical trials, the drug has shown to provide a sustained nootropic and anxiolytic effect which is useful for the treatment of generalized anxiety disorder (GAD).[1] Selank has an advantage over traditional anxiety treatments, such as benzodiazepines, as it has no sedating or negative cognitive side effects and no associated addiction or withdrawal problems.[citation needed]
Selank is closely related to another nootropic drug, Semax, also developed by the Institute of Molecular Genetics in Russia. This drug is currently available in Russian and Ukrainian pharmacies.[9]
As with all lyophilized peptides, it needs refrigeration to remain stable within sterile water solutions, such as bacteriostatic water concentrations.
