Selank
Tuftsin-derived heptapeptide studied for anxiolytic-like effects and stress-response modulation without sedation.
01 · What is Selank?
Selank is a synthetic heptapeptide analogue of tuftsin — an immunomodulatory fragment of immunoglobulin G — with a stabilizing Pro-Gly-Pro tail. Developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, it is studied for anxiolytic-like effects and stress-response modulation without the sedation associated with classical anxiolytics in published models. Like Semax, it is typically administered intranasally in research.
