Product profile

About TB500

TB-500 is a synthetic heptapeptide (sequence: Ac-LKKTETQ) that corresponds to amino acids 17–23 of the naturally occurring protein thymosin beta-4 (Tβ4), a key active region responsible for actin binding, cell migration, and wound healing. Thymosin beta-4 is a 43-amino acid peptide found in nearly all mammalian cells and plays important roles in tissue repair, anti-inflammation, and angiogenesis. TB-500 attempts to replicate selected biological activities of Tβ4, but it is not FDA‑approved for human use. The FDA classifies TB‑500 as a Category 2 bulk drug substance (substance of safety concern), and its manufacturing lacks regulatory oversight, raising concerns about purity and contamination. Currently, TB-500 remains an experimental compound; for example, a Phase 1/2 clinical trial is ongoing to evaluate its safety and tolerability in adults with stable atherosclerotic cardiovascular disease (ASCVD).

Main functions

  • 1.Promotes Angiogenesis and Tissue Repair: Preclinical studies show that Tβ4 and its fragments promote endothelial cell migration, capillary formation, and stabilization of new vascular networks, which are critical for tissue repair.
  • 2.Anti-Inflammatory Properties: Animal and in vitro studies indicate that TB‑500-related peptides can suppress inflammation, reduce microglial M1 polarization, and mitigate neuroinflammation.
  • 3.Enhances Cell Migration and Wound Healing: Through actin-binding activity, it influences cytoskeletal organization and promotes the migration of keratinocytes, corneal epithelial cells, and other cell types, accelerating re‑epithelialization.
  • 4.Potential Neuroprotective Effects: In a mouse model of Alzheimer’s disease, TB‑500 reduced Aβ‑induced neurite atrophy, inhibited neuronal apoptosis, and improved cognitive performance, suggesting potential applications in neurodegenerative conditions.

Recommended audience

  • Athletes and fitness enthusiasts seeking to accelerate recovery from muscle, tendon, and ligament injuries.
  • Individuals looking to promote wound healing or manage chronic ulcers (e.g., venous stasis ulcers).
  • Those interested in anti-aging or regenerative medicine approaches.
