Valproic acid, sodium salt
Histone deacetylase inhibitor (IC50 = 400 μM) that exhibits anticancer, anti-inflammatory and neuroprotective effects. Displays anticonvulsive activity via an increase in GABA levels and decreases Aβ production in animal models of Alzheimer's disease. Also attenuates NMDA-mediated excitation, blocks voltage-gated Na+ channels and modulates firing of neurons. Enables induction of pluripotent stem cells from somatic cells by Oct4 and Sox2. Can induce autophagy by inhibiting inositol synthesis. Identified by chemoinformatics as targeting human host proteins that interact with SARS-CoV-2.
Valproic acid, sodium salt is also offered as part of the Tocriscreen 2.0 Max, Tocriscreen Epigenetics Library and Tocriscreen Stem Cell Toolbox. Find out more about compound libraries available from Tocris.

Corresponding proteins were seen to play important roles in cellular activity and could influence several important pathways by treat with VPA.
We studied VPA's ability to alter expression of certain genes. Corresponding proteins were seen to play important roles in cellular activity and could influence several important pathways such as cell cycle control, differentiation, DNA repair, and apoptosis.

Rheumatoid Arthritis Poster
Rheumatoid arthritis (RA) is a chronic destructive inflammatory autoimmune disease that results from a breakdown in immune tolerance, for reasons that are as yet unknown. This poster summarizes the pathology of RA and the inflammatory processes involved, as well as describing some of the epigenetic modifications associated with the disease and the potential for targeting these changes in the discovery of new treatments.
