Valproic acid-d4 (sodium salt) is intended for use as an internal standard for the quantification of valproic acid (Item No. 13033) by GC- or LC-MS. Valproic acid is an analog of the natural fatty acid valeric acid that inhibits class I histone deacetylases (HDACs) with an IC50 value of approximately 2 mM.{17456} It decreases the number of axon branches in sensory neurons isolated from newborn rat dorsal root ganglia, an effect that is reversed by inositol-1,4,5-trisphosphate (1,4,5-IP3).{9786} In vivo, valproic acid inhibits amyloid-? deposition and neuritic plaque formation and decreases escape latency in the Morris water maze, indicating improved memory performance, in the APP23 transgenic mouse model of Alzheimer’s disease.{17458} Valproic acid has anticonvulsant activity in the pentylenetetrazol seizure threshold test in mice (ED50 = 0.71 mmol/kg) but induces neurotoxicity when administered at doses greater than or equal to 1.2 mmol/kg.{42211} Formulations containing valproic acid have been used to treat bipolar disorder and various seizure disorders.
