Valproic acid sodium salt (Sodium Valproate) 是一种HDAC 抑制剂，可抑制HDAC1的活性，诱导HDAC2的降解。它激活Notch1信号并抑制小细胞肺癌细胞的增殖。它可研究癫痫、偏头痛和双相情感障碍等。 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.
