According to the World Health Organization, the majority of people with epilepsy who live in developing
countries do not have access to high-quality treatment. Modern anticonvulsants are in high demand
since the unwanted effects of those compounds already in use make therapy difficult. The synthesis of
derivatives of 5,5-disubstituted-N3-[(2-aryl thiazolidine-4-one-3-yl)amino]hydantoins has been reported.
The position N3 of the hydantoin nucleus was substituted with 4-thiazolidinone moiety containing
aryl substituent at 2nd position with the goal of achieving the enhanced anticonvulsant effect.
Compounds 5c, 5d, 5l, 5r showed significant activity among the evaluated compounds compared to
control at dose of 45 mg/kg. The analysis of structural features revealed that the substitution of p-hydroxy
phenyl and cinnamyl substituted at 2nd position of thiazolidinone ring in 5,5-diphenyl-2,4-
imidazolidinedione and p-chloro phenyl, p-methoxy phenyl substituted at 2nd position of thiazolidinone
ring in (5,5-dialkyl)/(5-alkyl-5-substitutedphenyl)-2,4-imidazolidinedione skeleton enhanced the
anticonvulsant potentiality of the synthesized compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
