Valproic Acid is a small molecule histone deacetylase (HDAC) inhibitor that that exhibits anticancer, anti-inflammatory and neuroprotective effects . It has been shown to inhibit multiple pathways including the ERK, PKC and Wnt/β-Catenin pathways.  Valproic Acid has been shown to regulate the differentiation and proliferation of various cell types, including mesenchymal and hematopoietic stem cells, primary neurons, neuroblastomas and neural progenitor cells.
