Research profile
Anxiety-related signalling
Small clinical report
What it is and why it is studied
Selank is a seven-amino-acid peptide with the reference sequence Thr-Lys-Pro-Arg-Pro-Gly-Pro. Selank attracts research interest in anxiety-related signalling and peptide mechanisms. The linked clinical report brings together symptom measurements and a biological measure involving enkephalin activity.
What studies have found
A 2008 report compared Selank with medazepam in 62 people with generalised anxiety or neurasthenia. It described similar changes in anxiety measures and investigated changes in enkephalin activity alongside those observations.
This small active-comparator report is an early clinical signal, not conclusive placebo-controlled evidence of anxiety treatment, cognitive enhancement or long-term safety.

Understanding these details
A sequence describes the order of residues in a peptide. A molecular formula describes the atoms in the reference structure. Molar mass is expressed in grams per mole; it is not the amount in a vial. CAS numbers and PubChem identifiers help you find the corresponding chemical records.
