Valproic acid magnesium  (Synonyms: Magnesium valproate; VPA magnesium; 2-Propylpentanoic acid magnesium)

Cat. No.: HY-W794759
Handling Instructions Technical Support

Valproic acid magnesium (Magnesium valproate) is an orally active HDAC inhibitor, with IC50 in the range of 0.5 and 2 mM. Valproic acid magnesium inhibits HDAC1 (IC50, 400 μM), and induces proteasomal degradation of HDAC2. Valproic acid magnesium activates Notch1 signaling and inhibits proliferation in small cell lung cancer (SCLC) cells. Valproic acid magnesium is used in the epilepsy, bipolar disorder, metabolic disease, HIV infection and prevention of migraine headaches.

    Help & FAQs
    • Do most proteins show cross-species activity?

      Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
