The present invention concerns a family of sulfanilamide derivatives of formula (I) as anticonvulsant agents, where R is selected from optionally substituted C4-C9 alkyl, optionally substituted C6-C10 aryl, optionally substituted C6-C10 alkylenearyl and optionally substituted C5-C10heteroaryl R2 is selected from —H and optionally substituted C1-C6 alkyl each of R3 and R4, independently of each other, is selected from —H, optionally substituted C1-C6 alkyl, optionally substituted C6-C10 aryl and optionally substituted C5-C10 heteroaryl n is 0, 1, 2, 3 or 4. The derivatives have been prepared and their anticonvulsant profile was evaluated for the control of epileptic seizures.
