Selank — living evidence map

The Atlas page holds the claims; this is how its evidence evolved.

Summary

Selank is the heptapeptide Thr-Lys-Pro-Arg-Pro-Gly-Pro, reported to have prolonged anti-anxiety and nootropic effects. · pmid:30255741

Mechanism

In radioligand studies it acted as a positive allosteric modulator of GABA binding. · pmid:30255741

It dose-dependently inhibited the enzymatic breakdown of plasma enkephalin (IC50 15 micromolar), more potently than the peptidase inhibitors bacitracin and puromycin. · pmid:11550013

Identity

PubChem CID 11765600: Selank, C33H57N11O9, 751.9 g/mol. · pubchem:11765600

CAS registry number 129954-34-3. · pubchem:11765600

IUPAC name: (2S)-1-[2-[[(2S)-1-[(2S)-2-[[(2S)-1-[(2S)-6-amino-2-[[(2S,3R)-2-amino-3-hydroxybutanoyl]amino]hexanoyl]pyrrolidine-2-carbonyl]amino]-5-(diaminomethylideneamino)pentanoyl]pyrrolidine-2-carbonyl]amino]acetyl]pyrrolidine-2-carboxylic acid. · pubchem:11765600

Structure

No structure representation on record. PepJunkie draws only what an authoritative record supplies; for a peptide that is the residue sequence, and none has been curated for Selank yet.

Dose evidence, rung by rung

No established safe human dose. Nothing on file establishes one. That is a statement about the evidence PepJunkie holds, not a promise about the molecule.

  1. Approved-label dose · a resolved regulatory document names a labelled dose
