SELANK NASAL SPRAY

Selank nasal spray delivers a synthetic heptapeptide developed in Russia at the Institute of Molecular Genetics, Russian Academy of Sciences the same institute behind Semax. Selank is an analogue of tuftsin, a naturally occurring immunomodulatory tetrapeptide (Thr-Lys-Pro-Arg), extended with a Pro-Gly-Pro tail at the C-terminus. That added tail protects the molecule from rapid enzymatic breakdown, the same stabilizing design used in Semax. Because Selank descends from tuftsin rather than from a neurotransmitter or hormone, it sits in an unusual position: a peptide with both anxiolytic and immunomodulatory activity documented in the same research literature.

Lyophilized Research Compound

Technical Overview

Research indicates Selank modulates GABA-A receptor subunit expression rather than binding the benzodiazepine site directly — a mechanistic distinction that matters for the comparison below. It also influences serotonin and dopamine metabolism, and inhibits enkephalin-degrading enzymes, which raises levels of the body's own enkephalins. Additional work has reported effects on BDNF expression and, consistent with its tuftsin origin, measurable immunomodulatory activity in patients with anxiety-asthenic disorders.
