Description and Uses

Sodium 4-phenylbutyrate (4-PBA sodium) is an inhibitor of HDAC and endoplasmic reticulum (ER) stress, used in cancer and infection research.
Sodium phenylbutyrate stimulates urinary nitrogen excretion. It is a prodrug, which undergoes β-oxidation to phenylacetate. Sodium phenylbutyrate is used to treat urea cycle disorder. It might be associated with menstrual dysfunction, amenorrhea and painful mucositis of the esophagus and stomach.
Sodium phenylbutyrate has been used as an endoplasmic reticulum (ER) stress inhibitor to study the role of ER stress in the expression of betatrophin.

Sodium 4-Phenylbutyrate is a histone-deacetylase inhibitor.
