Mechanism of action
TB-500 is the synthetic form of Thymosin β4 (Tβ4), a 43-amino acid peptide. Its primary mechanism involves sequestration of G-actin, regulating actin polymerization that drives cell migration and proliferation. The peptide promotes angiogenesis (formation of new vessels) via surface receptor binding and internalization. Distinct active fragments have been identified: anti-inflammatory (amino acids 1-4), anti-apoptotic and cytoprotective (1-15), cell migration stimulation (17-23).
