Valproic Acid β-D-Glucuronide

Valproic Acid β-D-Glucuronide is a metabolite of Valproic Acid. Valproic Acid is a branched chain, fatty acid which is reported to potentially enhance central GABAergic neurotransmission and inhibit Na⁺ channels. Currently, the various molecular mechanisms of action of Valproic Acid have not been completely elucidated. Valproic Acid has been reported to be a potent inhibitor of histone deacetylases (HDACs) in vitro. Valproic Acid is also noted to relieve HDAC-dependent transcriptional repression and causes the hyperacetylation of histones in cultured cells. Additionally, Valproic Acid is reported to activate Wnt-dependent gene expression and to mimic trichostatin A in the inhibition of histone deacetylase.
