Synthesis and anticonvulsant activity of O-alkylated derivatives of 1-(2-naphthyl)-2-(imidazol-1-yl)ethanone oxime

In this study, O-alkylated derivatives of nafimidone oxime chemically, 1-(2-naphthyl)-2-(imidazol-1-yl)ethanone oxime have been synthesized as potential anticonvulsant compounds. O-alkylation of the oxime using hydrochlorides of various dialkylaminoethyl chlorides, methyl chloroacetate and alkyl dihalides gave the O-alkylated derivatives. Anticonvulsant activity of the compounds was determined against pentylenetetrazole induced convulsions in mice. The newly synthesized compounds exhibited moderate to significant activity compared to diazepam.
