Overview
Selank (TP-7) is a synthetic heptapeptide developed at the Institute of Molecular Genetics of the Russian Academy of Sciences, structurally based on the naturally occurring immunomodulatory peptide tuftsin (Thr-Lys-Pro-Arg) with an added Pro-Gly-Pro sequence for enhanced stability and CNS activity. Selank has been approved in Russia as an anxiolytic and nootropic agent. Published research describes its unique profile combining anxiolytic effects (comparable to benzodiazepines in some animal models) without sedative, amnestic, or dependence-producing properties. The peptide has been investigated for its dual immunomodulatory and neurotropic mechanisms, distinguishing it from classical anxiolytic compounds.

Mechanism of Action
Published research describes Selank as modulating GABAergic neurotransmission through allosteric interactions with GABA-A receptors, enhancing inhibitory signaling in limbic structures. Studies describe modulation of monoamine neurotransmitter systems including serotonin, norepinephrine, and dopamine. The peptide influences BDNF expression and enkephalin metabolism through inhibition of enkephalin-degrading enzymes, potentially contributing to its anxiolytic profile. As a tuftsin analog, Selank retains immunomodulatory properties including effects on IL-6, IFN-α/γ, and other cytokines. Gene expression studies describe modulation of inflammatory, chemokine, and neurotrophic gene networks.
