    Product Description

    Sodium 4-phenylbutyrate is a chemical chaperone that has been shown to rescue the trafficking of misfolded proteins.1,2 It also weakly blocks histone deacetylase activity (IC50 = 0.4 mM), which results in cell cycle arrest, differentiation, and/or apoptosis of various tumors.3,4 Formulations containing sodium 4-phenylbutyrate have been used for the treatment of urea cycle disorders.

    WARNING This product is not for human or veterinary use.
