COGNITIVE
Semax
Intranasal
Overview
A synthetic analog of the endogenous tetrapeptide tuftsin (Thr-Lys-Pro-Arg) with an added Pro-Gly-Pro sequence for stability. Selank exhibits anxiolytic activity comparable to benzodiazepines without sedation, dependence, or withdrawal effects.
Mechanism of Action
It modulates the expression of BDNF, serotonin, dopamine, and norepinephrine, and influences IL-6 and GABA receptor expression.
​Research Summary & Key Findings
Approved in Russia for generalized anxiety disorder and as a nootropic. Clinical trials showed anxiolytic effects comparable to medazepam without sedation. Demonstrated immunomodulatory properties through modulation of IL-6 and T-helper cell balance.
Clinical Status
INVESTIGATING
Selank is in the investigational stage. While preclinical and early-phase data exist, it has not received regulatory approval for clinical use in the United States.
