"Anticonvulsant Activities of New 1,4-dihydropyridine Derivatives Containing 4-nitroimidazolyl Substituents "

Abstract

Anticonvulsant activity of Alkyl, cycloalkyl and arylalkyl ester analogues of nifedipine in which the ortho-nitro phenyl group at position 4 is replaced by 1-methyl-4-nitro-5-imidazolyl substituent, were determined against pentylenetetrazole-induced seizures in mice. The anticonvulsant effects of the compounds were evaluated by the measurement of seizure latency and duration. Significant differences were observed between treated animals with control group and nifedipine in seizure duration. Our results show that most of the compounds had similar activity to the reference drug nifedipine. In addition, compounds 6a, 6b, 6f, 6g, 6h, 8e, 8f, 8g , 8h and 8i were more active than the reference drug nifedipine
