• Benzofurazanyl
• Benzo[d][1,3]dioxo-6-yl
• 1,4-Dihydropyridine
• Anticonvulsant activity
• Antinociceptive activity

The present study is on the development of dialkyl 4-(benzo[d][1,3]dioxol-6-yl)-1,4-dihydro-2,6-dimethyl-1-substituted pyridine-3,5-dicarboxylate derivatives as isosteric analogues of isradipine and nifedipine, by the replacement of benzofurazanyl and 2-nitrophenyl groups respectively with benzo [d][1,3]dioxo-6-yl group, as potential anticonvulsants. Fifteen new derivatives (8a-8o) were synthesized and tested for anticonvulsant activity using maximal electroshock and subcutaneous pentylene-tetrazole induced seizure methods. Compound 8f possessing free NH group in 1,4-dihydropyridine ring, diethyl ester functionality at the positions 3 and 5 showed significant anticonvulsant and antioxidant activities. This was also supported by molecular properties prediction data. Selected compounds were evaluated for antinociceptive activity in capsaicin induced nociception assay at 10 mg/kg body weight, but displayed no significant activity at the tested dose.
