TB-500 is a synthetic analog of the naturally occurring 43-amino-acid protein Thymosin Beta-4, representing the active fragment (residues 17–23) studied for its bioactivity and stability in laboratory settings.
Research focus: Research centers on TB-500’s actin-sequestering activity — it binds monomeric G-actin, which in preclinical models enables rapid cytoskeletal remodeling relevant to cell migration during tissue repair. Studies have reported increased VEGF expression (angiogenesis), accelerated wound closure in diabetic animal models, reduced infarct size in cardiac models, and increased tensile strength in tendon-repair models.
