Selank, originating from Russia, stands as a brief peptide
possessing both nootropic and anxiolytic attributes.
Serving as a synthetic counterpart to the naturally existing
Tuftsin, an immunomodulatory peptide, Selank mirrors
Tuftsin closely, differing mainly by containing an additional
four amino acids in its chain. This modification aids in
enhancing its metabolic stability and extending its half-life.
Notably, Selank, like Tuftsin, influences IL-6, T helper cells,
monoamine neurotransmitters, and brain-derived
neurotrophic factor (BDNF). The fundamental similarities
between Selank and Tuftsin lie in their structure, with
Selank’s slight alteration in amino acids contributing to
improved stability and longevity.
Clinical trials have explored Selank’s potential application
as a treatment for generalized anxiety disorder.
