We present here the synthesis of 3- and 4-benzoylpyridine oxime derivatives with potential anticonvulsant action. The most active compound in the maximum electric shock test was 4-benzoylpyridine O-2-morpholinoethyloxime oxalate (1a), i.p. doses of 60 – 150 mg/kg of which increased the survival of mice to 100%. The best effect in the corasol antagonism test was obtained with 4-benzoylpyridine O-(isonicotinoyl)oxime (2c), i.p. doses of 12.5 mg/kg of which increased the survival of mice to 67% and the latent period of onset of generalized tonic-clonic convulsions to 52 sec. Compound 1a had low toxicity (the i.p. LD50 in mice was 316 mg/kg) and a therapeutic index of 21.
