DescriptionECHEMI Editorial ReferenceSelank is a synthetic derivative of the tetrapeptide tuftsin that contains a proline-glycine-proline sequence at the C-terminus and has anxiolytic and anti-inflammatory activities. It increases the amplitude and discharge rate of inhibitory postsynaptic currents of neurons in the rat hippocampal CA1 region when used at a concentration of 1 μM. It decreases the level of affective responses and the number of erroneous escape attempts in rats in an acute stress situation, increases orientational-investigative responses of rats in an unfamiliar situation, and reduces the time mice spend immobile in the forced swim test. It increases locomotor activity of high-anxiety Balb/c, but not C57Bl/6, mice in the open field test. Selank (0.01 mg/kg) decreases verticalization induced by apomorphine in mice. It also decreases expression of the inflammation-related genesIl2rgandXcr1in mouse spleen after 90 minutes when administered at a dose of 100 μg/kg.
SELANK Synthetic is a single, non-glycosylated polypeptide chain containing 7 amino acids, having a molecular mass of 751.89 Dalton and a Molecular formula of C33H57N11O9.Certificates-

Class:
Actin-sequestering protein / 43-amino-acid peptide
Status:Research compound — Not FDA approved (investigational: RGN-259 for dry eye / neurotrophic keratitis)
Mechanism:A naturally occurring 43-amino-acid peptide (Ac-Ser-Asp-Lys-Pro-Asp-Met-Ala-Glu-Ile-Glu-Lys-Phe-Asp-Lys-Ser-Lys-Leu-Lys-Lys-Thr-Glu-Thr-Gln-Glu-Lys-Asn-Pro-Leu-Pro-Ser-Lys-Glu-Thr-Ile-Glu-Gln-Glu-Lys-Gln-Ala-Gly-Glu-Ser-OH) that binds G-actin (sequesters monomeric actin), preventing F-actin polymerization. Promotes cell migration, angiogenesis, wound healing, and anti-inflammatory responses via integrin-linked kinase (ILK) and HIF-1α/VEGF pathways. TB-500 is the synthetic fragment Ac-LKKTETQ (MW ~895) often sold under this CAS.
Activity note:Thymosin Beta-4 is an actin-binding protein, not a receptor agonist. Functional activity is measured by actin sequestration (Kd ~0.7–1 μM) and cell migration assays, not EC₅₀.
