Sulfonamide derivatives of thiazolidin-4-ones with anticonvulsant activity against two seizure models: Synthesis and pharmacological evaluation

摘要

A series of 4-thiazolidinones bearing a sulfonamide group (4aw) were prepared by cyclizing various 5-bromo-2-methoxy-N'-[(1E)-arylmethylene/ arylethylidene]benzenesulfonohydrazides. All the compounds were characterized by IR, 1H NMR, and elemental analysis. The compounds were tested for their anticonvulsant activity utilizing MES and scPTZ animal models. The majority of the compounds exhibited significant activity against both animal models; however, compounds 4c, 4m, and 4o displayed promising activity and could be considered as leads for further investigations.
