Abstract
A series of 4-thiazolidinones bearing a sulfonamide group (4a-w) were prepared by cyclizing various 5-bromo-2-methoxy-N'-[(1E)-arylmethylene/arylethylidene] benzenesulfonohydrazides. All the compounds were characterized by IR, H-1 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.
