Valproic Acid (2-Propylpentanoic Acid) is an HDAC inhibitor that inhibits HDAC1 activity, induces HDAC2 degradation, and is orally active. Valproic Acid can be used in epilepsy and bipolar disorder research.

(±)-Pantothenic acid ((±)-Pantothenate), a B-vitamin, is essential for coenzyme A (CoA) biosynthesis in mammalian cells and exhibits protective activity against valproic acid (VPA)-induced neural tube defects (NTD) in CD-1 mice [1].

The combination of Valproic acid with Coumarin-3-carboxylic acid (3-Carboxycoumarin) suppresses the proliferation and migration of lung cancer cells via EGFR/VEGFR2/c-Met-Akt-NF-κB signaling pathways; this combination may have a wide therapeutic and/or adjuvant therapeutic application in the treatment of lung cancer.

1. p-Hydroxybenzaldehyde (p-Oxybenzaldehyde) shows an inhibitory effect on the GABA transaminase to contribute to an antiepileptic and anticonvulsive activity, and its inhibitory activity was higher than that of valproic acid, a known anticonvulsant.
