77591-33-4 Usage


Thymosin beta 4 acetate is an endogenous peptide that plays a crucial role in hormone regulation, wound healing, and cardioprotection. It is involved in pro-angiogenic and fibroblast-activating activities, and exhibits immunomodulatory and cardioprotective properties. Thymosin beta 4 acetate also binds to G-actin filaments, preventing actin polymerization.


Used in Pharmaceutical Industry:
Thymosin beta 4 acetate is used as a therapeutic agent for various medical conditions, including wound healing, cardiovascular diseases, and immune disorders. Its immunomodulatory and cardioprotective properties make it a promising candidate for the treatment of various conditions.
Used in Cosmetic Industry:
Thymosin beta 4 acetate is used as an active ingredient in cosmetic products for its wound healing and anti-aging properties. It promotes skin regeneration and improves skin elasticity, making it a valuable component in skincare formulations.
Used in Research Applications:
Thymosin beta 4 acetate is used as a research tool for studying the mechanisms of actin polymerization, wound healing, and immune responses. It helps researchers gain insights into the biological processes and develop novel therapeutic strategies for various diseases.


Thymosin Beta-4 is a 43-amino-acid peptide that promotes healing throughout the body. It also has anti-inflammatory properties. Found naturally in higher concentrations at injury sites, the water-soluble protein can repair tissue damage and regulate cell migration to a site. It can improve wound healing and repair not only the skin, but also the brain, spinal cord, and heart. Medical professionals consider Thymosin Beta-4 a safe and powerful substance in its natural or synthetic form known as TB-500.In addition, TB4 has a low molecular weight and doesn’t bind to the extracellular matrix. This enables it to easily travel throughout body tissues, which promotes a faster rate of healing. The peptide travels long distances, so it usually doesn’t have to be injected directly at the injury site. While some believe injecting it closer to an injured area yields better results, clinical evidence suggests otherwise.

Check Digit Verification of cas no

The CAS Registry Mumber 77591-33-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,7,5,9 and 1 respectively; the second part has 2 digits, 3 and 3 respectively.
Calculate Digit Verification of CAS Registry Number 77591-33:
164 % 10 = 4
So 77591-33-4 is a valid CAS Registry Number.
