Selank

TKPRPGP tuftsin analogue — ≠ Semax ≠ Adamax; no US FDA anxiety assumption.

Editorial review:
What evidence says

Evidence snapshot

This drawer marks papers. It is not a plan, a dose, or a source. A paper is a bounded report. It is not a protocol. Grades name the object. They are not a safety rating.

Identity lock. Selank is the synthetic heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro (TKPRPGP), a tuftsin analogue with a C-terminal Pro-Gly-Pro extension. PubChem CID 11765600 (hard-separate from Semax CID 9811102 and Adamax TBD); formula C33H57N11O9 / MW 751.9; CAS 129954-34-3. Selank ≠ Semax; ≠ Adamax (batch D); ≠ tuftsin alone. Russian clinical program papers exist for anxiety indications in that jurisdiction’s literature; do not assume a US FDA-approved anxiety drug object. This drawer marks papers. It is not use advice.

Bottom line

Human literature includes Russian-language anxiety-treatment optimization reports. Mechanistic and rodent work covers GABAergic gene expression, stress/anxiety models, ethanol-memory interactions, and a joint Selank–Semax connectomic imaging study. Tuftsin-analogue reviews provide class context. Refuse interchangeable “nootropic peptide” glow with Semax.

Papers

Human / clinical-program (jurisdiction-sensitive)

PMID 26356395 — Medvedev 2015

Tested: optimization of treatment of anxiety disorders with Selank (clinical-program report).

Does not show: a US FDA approval package, or equivalence to Semax stroke literature.

PMID 34396551 — Doyno 2021

Tested: secondary review of sedative-hypnotic / GABA-impacting agents that mentions Selank among other agents.

Does not show: a primary Selank pivotal RCT.

Mechanism / behavioral (preclinical & cellular)

PMID 28293190 — Filatova 2017

Tested: GABA, Selank, and olanzapine effects on GABAergic neurotransmission gene expression in IMR-32 cells.

Does not show: human clinical efficacy by itself.

PMID 26924987 — Volkova 2016

Tested: Selank administration effects on expression of genes involved in GABAergic neurotransmission.

Does not show: a labeled anxiety indication outside study jurisdiction framing.

PMID 28280289 — Kasian 2017

Tested: Selank enhances diazepam’s anxiolytic effect under unpredictable chronic mild stress in rats.

Does not show: human combination-therapy approval.

PMID 31625062 — Kolik 2019

Tested: Selank protection against ethanol-induced memory impairment via BDNF regulation in rat brain regions.

Does not show: human AUD cognition indication.

Tested: Selank attenuates aversive signs of morphine withdrawal in rats.

Does not show: human addiction-therapy approval.

PMID 14552529 — Kozlovskaya / Kozlovskii 2003

Tested: optimizing action of synthetic peptide Selank on conditioned active avoidance reflex in rats.

Does not show: modern human RCT endpoints.

PMID 30255741 — Vyunova 2018

Tested: molecular aspects of heptapeptide Selank biological activity (peptide anxiolytic framing).

Does not show: a new primary clinical trial.

Class / joint imaging context

PMID 28745220 — Siebert 2017

Tested: review of tuftsin properties and analogs (Selank as tuftsin analogue class context).

Does not show: Selank-specific pivotal efficacy.

PMID 32342318 — Panikratova 2020

Tested: functional connectomic approach to studying Selank and Semax effects (imaging; both objects).

Does not show: that Selank and Semax are interchangeable.

What is not established

US FDA approval as an anxiety or nootropic drug. Interchangeability with Semax or Adamax. That rodent GABA/BDNF papers equal labeled human efficacy worldwide. Product identity of unlabeled vials vs characterized Selank. This drawer does not provide use advice, schedules, or sourcing.
