Phenylbutyrate reversibly inhibits class I and II histone deacetylases (HDACs), which may result in a global increase in gene expression, decreased cellular proliferation, increased cell differentiation, and the induction of apoptosis in susceptible tumor cell populations. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
