Selank

Selank Peptide

Selank is a short, synthetic heptapeptide composed of seven amino acids. Selank was developed to mimic the naturally occurring peptide Tuftsin,⁽⁵⁾ a short fragment from the immunoglobulin G (IgG), a natural tetrapeptide involved in certain biological functions that regulate the immune system. After the discovery and initial isolation of Tuftsin, researchers suggested that the peptide might be involved in the functions of phagocytic cells, including phagocytosis, motility, and immunological cell functions.⁽²⁾ Since then, various synthetic analogs of Tuftsin have been synthesized in laboratories by conventional and polymeric reagent methods.⁽⁴⁾
