What it is

Selank is a synthetic heptapeptide built on the tuftsin sequence with a C-terminal Pro-Gly-Pro extension that increases stability against enzymatic degradation.

In pre-clinical research it is used as a reference compound for GABAergic and neuropeptide-signaling assays. Supplied strictly for laboratory use.

Reconstitution & storage

  • Reconstitute with bacteriostatic water — add slowly down the vial wall and swirl gently; do not shake.
  • Store lyophilized vials at -20°C; once reconstituted keep at 2–8°C and use within 16 weeks.
  • Protect from light and avoid repeated freeze–thaw cycles.

    In a Russian comparative study of 62 patients diagnosed with generalized anxiety disorder or neurasthenia, 30 received selank and 32 received medazepam, with symptom ratings collected on the Hamilton, Zung and CGI scales and enkephalin-degrading activity measured in blood serum.

    Rats were given selank or GABA at 300 ug/kg and expression of 84 neurotransmission-related genes was measured in frontal cortex tissue at 1 hour and 3 hours after administration, with 45 genes altered at 1 hour and 22 at 3 hours.

    Expression of 84 GABAergic-system genes was measured in cultured IMR-32 human neuroblastoma cells exposed to GABA, selank or olanzapine alone and in combination; the authors report no change in the mRNA levels of the genes studied under the effect of selank alone.

    Male Wistar rats were assessed in the elevated plus maze after administration of selank, diazepam, or the two combined, with and without an unpredictable chronic mild stress protocol; the authors report the combination as most effective under stress conditions, while in unstressed animals the treatments initially shifted anxiety indicators in the opposite (anxiogenic) direction.

    Selank at 0.3 mg/kg was tested against diazepam at 2 mg/kg in a naloxone-precipitated morphine withdrawal model in outbred rats, with withdrawal signs and tactile sensitivity thresholds scored.
