Central actions of pro-2-PAM (dihydroderivative of 2-PAM) and 2-PAM in poisonings with DFP have been studied. It was shown that pro-2-PAM significantly increased activity of DFP inhibited acetylcholinesterase in the brain, quickly ceased the DFP-induced paralysis of respiration, partially normalized the DFP-induced abnormalities in electrocorticogram and increased the convulsive dosis of DFP. Effects of 2-PAM in these experiments were negligible.

The synthesis and pharmacological screening of a series of new phenylsuccinimide derivatives are described. Seven compounds of that series elicited a marked anticonvulsant activity. Among the compounds tested, interesting structures were those metasubstituted with bromine, fluorine or trifluoromethyl group. The most interesting drug seems to be the N-morpholinemethyl derivative of mbromophenylsuccinimide, which has a long duration of activity, elicits a very strong antipentetrazole action, and gives good protection against maximal electroshock seizures.
