valproic acid sodium salt

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-d14 (sodium) is the deuterated form of Valproic acid (sodium). Valproic acid sodium salt (Sodium Valproate) acts as an HDAC inhibitor, with an IC50 range of 0.5-2 mM, and inhibits the activity of HDAC1 (IC50, 400 μM) while also promoting the degradation of HDAC2. It activates the Notch1 signaling pathway and suppresses the proliferation of small cell lung cancer (SCLC) cells. Additionally, Valproic acid sodium salt is applicable in research related to epilepsy, bipolar disorder, and migraines.
