A review

Valproic acid (VPA; 2-n-propylpentanoic acid) is widely used as a major drug in the treatment of epilepsy and in the control of several types of seizures. Being a simple fatty acid, VPA is a substrate for the fatty acid P-oxidation (FAO) pathway, which takes place primarily in mitochondria. The toxicity of valproate has long been considered to be due primarily to its interference with mitochondrial P-oxidation. The metabolism of the drug, its effects on enzymes of FAO and their cofactors such as CoA and/or carnitine will be reviewed. The cumulative consequences of VPA therapy in inborn errors of metabolism (IEMs) and the importance of recognizing an underlying IEM in cases of VPA-induced steatosis and acute liver toxicity are two different concepts that will be emphasized

New chemistry with anionic NNN pincer ligands

The use of tridentate anionic pincer ligands in organometallic chemistry has gained considerable importance, particularly in the field of homogenous catalysis. This chapter focuses on the recent developments of anionic tridentate NNN pincer ligands from their synthesis to coordination chemistry and their applications in forming stable transition metal complexes for applications in catalytic transformations
