Abstract:
A series of 5-[(N-substituted benzylidenylimino)amino]-2-oxo/thiobarbituric acids (3a-3h) have been synthesized by the condensation of 5-hydrazino-2-oxo/thiobarbituric acids (2a-2b) with various aromatic aldehydes. Cycloaddition of thioglycolic acid to 3a-3h, yielded 5-[(2'-substituted phenyl-4'-oxothiazolidin-3'-yl)amino]-2-oxo/thiobarbituric acids (4a-4h). All these compounds were screened, in vivo, for their anticonvulsant activity and acute toxicity studies. Compounds 4f and 4g were found to be most potent compounds of this series and were compared with the reference drugs, phenytoin sodium, lamotrigine and sodium valproate. The structures of these compounds have been established by IR, 1H NMR and mass spectroscopic data.
