PATENT EXAMPLES The ability of selected 2-methylpropanamide derivatives to block maximal electroshock-induced seizures (MES) was determined by the following procedure.

Seizures were induced by application of current (50 mA, 60 pulses/sec, 0.8 msec pulse width, 1 sec duration, D.C.) using a Ugo Basile ECT device (model 7801). Mice were restrained by gripping the loose skin on their dorsal surface and saline-coated corneal electrodes were held lightly against the two cornea. Current was applied and mice were observed for a period of up to 30 sec for the occurrence of a tonic hindlimb extensor response. A tonic seizure was defined as a hindlimb extension in excess of 90 degrees from plane of the body. The 2-methylpropanamides tested were administered iv to mice 10 min before the test procedure.
