    Anxiolytic Heptapeptide

    Calm Without Sedation: The Tuftsin Analog That Matches Benzodiazepines

    Selank is a synthetic heptapeptide analog of tuftsin (sequence: Thr-Lys-Pro-Arg-Pro-Gly-Pro) engineered for enhanced metabolic stability. In clinical trials for generalized anxiety disorder, Selank matched the anxiolytic efficacy of medazepam (a benzodiazepine) while adding anti-asthenic and psychostimulant benefits — without sedation, cognitive impairment, or dependence potential. This unique "calm yet clear" profile makes it central to anxiety and cognition research.

    • Heptapeptide: Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP)
    • Tuftsin analog with glyproline motif for stability
    • Anxiolytic efficacy comparable to benzodiazepines
    • No sedation, amnesia, or dependence potential
    • Anti-asthenic (energy-boosting) properties
    Multi-Axis Mechanism

    How Selank Achieves Anxiolysis Without Trade-Offs

    Selank operates through a rare multi-system mechanism. It modulates 52 GABA-related genes, increases hippocampal BDNF, and inhibits enkephalin-degrading enzymes (IC₅₀ ~20 µM) — prolonging the body's natural anti-stress peptides. Unlike benzodiazepines that directly enhance GABA receptor activity, Selank changes receptor affinity through gene expression, explaining its synergy with classical anxiolytics and lack of tolerance development.

    • Modulates 52 genes related to GABA signaling
    • Increases BDNF in hippocampus (intranasal-confirmed)
    • Inhibits enkephalinases (preserves endogenous anti-stress peptides)
    • Regulates IL-6 and 34 inflammation-related genes
    • Alters GABA receptor affinity (not direct agonism)
    Research Applications

    From Memory Enhancement to Pain Modulation

    Selank research extends far beyond anxiety. Studies demonstrate enhanced memory trace stability independent of anxiety reduction — suggesting direct nootropic properties. It modulates 36 hippocampal genes encoding plasma membrane proteins involved in learning. Pain research shows enkephalinase inhibition helps protect natural analgesic peptides. Additional applications include immune modulation, cognitive rescue after brain injury, and even antiviral activity against influenza A.

    • Memory and learning: Enhanced trace stability, 36 hippocampal genes
    • Pain modulation: Enkephalinase inhibition preserves natural analgesia
    • Cognitive rescue: Restores function after neurotoxin damage
    • Immune modulation: IL-6 suppression, 34 cytokine-related genes
    • Antiviral research: Activity against influenza A/H3N2
