Selank Spray

Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro) is a synthetic analog of the endogenous immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg), developed at the Institute of Molecular Genetics of the Russian Academy of Sciences. It exhibits resistance to enzymatic degradation via a C-terminal Pro-Gly-Pro extension. Research has documented its interaction with the GABAergic system, BDNF expression modulation, and serotonergic pathways, contributing to its investigated anxiolytic profile in the absence of sedation. Additionally, immunological studies indicate upregulation of IL-6 and enkephalin expression. The intranasal atomizer delivery format is intended to investigate bioavailability via the nasal mucosal route and potential CNS access through olfactory pathways.
