Eleven kinds of 5-alkylamides of L-and DL-glutamic acid were synthesized and assessed for anticonvulsant effects. Against lethal convulsion induced by caffeine, maximum efficacy was observed with alkylamides possessing C7 to C8 alkyl radicals in the position 5 of glutamic acid, and the compounds having C5 to C7 alkyl groups were shown to have the highest toxity. Differences in the response between L-compound and DL-compound are not significant. Synthesized ω-alkylamides of L-glutamic acid, L-aspartic acid and DL-2-aminoadipic acid did neither increase nor decrease the oxygen consumption by the rat brain cortex slices.
