Additional Information:

Sodium valproate is a histone deacetylase inhibitor (IC50 = 400µM) (1). This compound demonstrates neuroprotective, anticancer, and anti-inflammatory activity (2). It also inhibits Aβ production, reduced neuritic plaque formation, and improved memory deficits in Alzheimer’s mouse models (3), improves stem cell reprogramming efficiency and enables efficient induction of pluripotency without introduction of the oncogene c-Myc (4) and is clinically a useful anticonvulsant.
