Abstract
2-Propyl-2-pentanoic acid (valproic acid) esters and (E)-2-propyl-2-pentenoic acid [(E)-2-valproenoic acid] esters surprisingly proved to have valuable properties, in that they show anticonvulsive and antiepileptic activities comparable with those of valproic acid, as well as an improved bioavailability and a markedly reduced toxicity.
