    Brief Introduction of TB500:

    TB500 (a synthetic molecule derived from the active domain of thymosin β4) is primarily used in anti-fibrosis and wound repair research. Specific applications include:


    1) Tissue Repair and Angiogenesis:

    TB500 accelerates wound healing and skin repair by inhibiting the Akt signaling pathway and promoting endothelial cell differentiation, dermal angiogenesis, keratinocyte migration, and collagen deposition.

    2) Anti-inflammatory Effects:

    Its active ingredients can reduce inflammatory responses, creating a favorable environment for tissue repair.

    3) Experimental Research:

    TB500 is commonly used in in vitro cell-based assays (such as T cell proliferation and cell survival promotion) and animal model studies. The solvent formulation should be adjusted according to experimental requirements

    TB500 Introduction

    TB500, also known as Thymosin Beta 4 Fragment 17-23, is a synthetic peptide consisting of seven amino acids. It is the bioactive fragment derived from naturally occurring Thymosin Beta 4.
    It modulates actin activity to facilitate cell migration, angiogenesis and tissue remodeling. It exerts systemic effects and may support the recovery process of tissues throughout the body.
    Research indicates potential application prospects for soft tissue maintenance, skin wound recovery and joint health. It was initially researched for tendon care in equine veterinary applications.                                                                Shop The original Chinese-produced TB500 freeze-dried raw material powder, with CAS number 885340-08-9, is used for wound repair research.-Detailed Image 2

    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.
