NCI Drug Dictionary


valproic acid 
A synthetic derivative of propylpentanoic acid with antiepileptic properties and potential antineoplastic and antiangiogenesis activities. In epilepsy, valproic acid appears to act by increasing the concentration of gamma-aminobutyric acid (GABA) in the brain. This agent's antitumor and antiangiogenesis activities may be related to the inhibition of histone deacetylases and nitric oxide synthase, which results in the inhibition of nitric oxide synthesis. Check for active clinical trials or closed clinical trials using this agent. (NCI Thesaurus)
