    Selank as a nootropic
    Recreationally Selank is used to improve one's ability to focus and concentrate, reduce mental fatigue, increase mental sharpness and increase memory and learning capacity. The first noticeable effect is usually stabilization of mood and general feeling of well-being.

    Selank as an antiviral agent
    Selank neuropeptide also expresses immunomodulatory effects. In 2009 a study by F. Ershov et all. has evaluated antiviral properties of Selank both in vitro and in vivo against the influenza virus strain A/Aichi 2/68 (H3N2). The pronounced antiviral effect of Selank was detected in both systems. The highest efficiency - completely supressed viral reproduction was shown when Selank was added to the cell culture 24 hours before inoculation.  Shop TB500 Peptide CAS 885340-08-9 2mg5mg 10mg High quality TB500 885340-08-9 peptide-Detailed Image 1

    Research
    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.
