Application

VAHA may be used in cell signaling studies.

Biochem/physiol Actions

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.
VAHA (Valproyl hydroxamic acid) is an HDAC inhibitor with less activity than valproic acid against Class I enzymes but much greater Class II activity

Inositol-1,4,5-trisphosphate (InsP3) depletion has been implicated in the therapeutic action of bipolar disorder drugs, including valproic acid (VPA). It is not currently known whether the effect of VPA on InsP3 depletion is related to the deleterious effects of teratogenicity or

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
