An Expert Monograph on Thymosin Beta-4 (Timbetasin): Mechanisms, Clinical Development, and Therapeutic Potential

Executive Summary

Thymosin beta-4 (Tβ4), also known by the recommended International Nonproprietary Name (INN) timbetasin, is an investigational, naturally occurring 43-amino acid peptide with a remarkable array of biological activities centered on tissue protection, repair, and regeneration. This monograph provides a comprehensive analysis of Tβ4, synthesizing its physicochemical properties, dual mechanisms of action, extensive preclinical evidence, and complex clinical development history. The therapeutic rationale for Tβ4 is founded on its pleiotropic functions, which include potent pro-migratory, pro-angiogenic, anti-inflammatory, anti-apoptotic, and anti-fibrotic effects. These activities stem from a unique dual-mechanism profile: intracellularly, it is the primary G-actin sequestering protein, regulating cytoskeletal dynamics, while extracellularly, it functions as a "moonlighting" signaling molecule released at sites of injury to orchestrate the entire healing cascade.
