VAHA (Valproyl hydroxamic acid) is an HDAC inhibitor with less activity than valproic acid against Class I enzymes but much greater Class II activity
VAHA is an HDAC inhibitor
Hydroxamic acid derivatives of valproic acid exhibit anticonvulsant activity with no teratogenic activity in mouse neural tube defect model. It is effective in the treatment of bipolar disorders.

Application

VAHA may be used in cell signaling studies.

Fluorinated and non-fluorinated valproic acid (VPA) analogues with hydroxamic acid moieties were tested for their teratogenic, anticonvulsant and neurotoxic potencies in mice. Compounds were synthesized from their corresponding acids. The induction of neural tube defects (exencephaly) of the resulting hydroxamates
