valproic acid sodium

Valproic acid sodium salt (Sodium Valproate) is the sodium salt form of valproic acid with anti-epileptic activity. Valproic acid sodium salt is converted into its active form, valproate ion, in blood. Although the mechanism of action remains to be elucidated, Valproic acid sodium salt increases concentrations of gamma-aminobutyric acid (GABA) in the brain, probably due to inhibition of the enzymes responsible for the catabolism of GABA. This potentiates the synaptic actions of GABA. Valproic acid sodium salt may also affect potassium channels, thereby creating a direct membrane-stabilizing effect.

Valproic Acid (2-Propylpentanoic Acid) is an HDAC inhibitor that suppresses HDAC1 activity and induces HDAC2 degradation, exhibiting oral bioavailability. Valproic Acid activates Notch1 signalling and inhibits the proliferation of small cell lung carcinoma cells, making it applicable for research into epilepsy and bipolar disorder.

Divalproex Sodium (Valproate semisodium) binds to and inhibits gamma-aminobutyric acid (GABA) transaminase and its anticonvulsant activity may be exerted by increasing brain concentration of GABA and by inhibiting enzymes that catabolize GABA or block the reuptake of GABA into glia and nerve endings. It also is an HDAC inhibitor, Comprised of sodium valproate and valproic acid with anticonvulsant and antiepileptic activities. Divalproex may also work by suppressing repetitive neuronal firing through the inhibition of voltage-sensitive sodium channels.
