C33H57N11O9 · 751.87 Da · CAS 129954-34-3
Heptapeptide based on tuftsin. Studied for anxiolytic and cognitive pathways via GABA modulation.
01 · Overview
Selank is a synthetic heptapeptide analog of the immunomodulator tuftsin, developed at the same Russian institute as Semax. Its sequence — Thr-Lys-Pro-Arg-Pro-Gly-Pro — is modified to extend pharmacological half-life relative to the parent tuftsin tetrapeptide.
Published research has examined anxiolytic effects via GABAergic and tuftsin-receptor pathways, metabolic stability in plasma, and its potential as a non-sedating anxiolytic reference compound in rodent behavioral assays. Alvar supplies Selank as a free-base solution.
