General description

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.

Application

Sodium phenylbutyrate has been used as an endoplasmic reticulum (ER) stress inhibitor to study the role of ER stress in the expression of betatrophin.

Biochem/physiol Actions

Sodium phenylbutyrate is a histone deacetylase inhibitor.
