title: Synthesis, characterization and anticonvulsant activity evaluation of some 1,4-dihydropyridines and 3,5-(substituted)oxycarbonyl-1,4-dihydro-2,6-dimethyl-N-[2-(4-sulfamoylphenylamino)-acetyl]-4-(substituted)pyridines.
abstract: A series of 3,5-(substituted)oxycarbonyl-1,4-dihydro-2,6-dimethyl-4-(substituted)pyridines (1a-j) were synthesized by Hantzsch method for pyridine synthesis. Treatment with chloroacetyl chloride produced N-(2-chloroacetyl)-3,5-(substituted)oxycarbonyl-1,4-dihydro-2,6-dimethyl-4-(substituted)pyridines (2a-e), which on further treatment with sulfanilamide resulted in 3,5-(substituted)oxycarbonyl-1,4-dihydro-2,6-dimethyl-N-[2-(4-sulfamoylphenylamino)-acetyl]-4-(substituted)pyridines (3a-e). The structures has been established on the basis of spectral (IR, 1H-NMR, mass) and elemental analysis. Compounds 1a-j and 3a-e (5 mg/kg and 10 mg/kg) were evaluated for their anticonvulsant effect against pentylenetetrazole-induced convulsions with diazepam (4 mg/kg) as the reference. Compounds 3a-e exhibited significant (p<0.01) anticonvulsant activity compared to the control.
