Also known as: Thr-Lys-Pro-Arg-Pro-Gly-Pro, tuftsin analog, TP-7
Selank (Thr-Lys-Pro-Arg-Pro-Gly-Pro, TP-7) is a synthetic heptapeptide analog of tuftsin with an estimated rat plasma half-life of 7–10 minutes based on in vivo degradation studies. No human pharmacokinetic study has been published. Direct olfactory nerve delivery via intranasal administration provides extended CNS exposure beyond the short plasma half-life. Proposed mechanisms include GABA-A receptor modulation at the benzodiazepine binding site, enkephalinase inhibition, and serotonin/dopamine modulation. Produces anxiolytic effects without sedation, muscle relaxation, or dependence potential. Approved in Russia as Selank 0.15% nasal spray.
