title: Anticonvulsant activity of some 4-aminobenzanilides.
abstract: A series of 4-aminobenzanilides derived from ring-alkylated anilines were prepared and evaluated for anticonvulsant activity. These benzanilides were prepared in the course of studies designed to determine the relationship between the benzamide structure and anticonvulsant effects. The compounds were tested in mice against seizures induced by electroshock and metrazole (pentylenetetrazole) and in the rotorod assay for neurologic deficit. All of the 4-aminobenzanilides showed activity at doses of 300 mg/kg against maximal electroshock seizures (MES). The 4-aminobenzanilide derived from 2,6-dimethylaniline (8) was the most potent anti-MES compound with an ED50 of 2.60 mg/kg and a protective index of 5.77 (PI = TD50/ED50). The activity profile for 8 compares quite favorably with that for phenobarbital and phenytoin in the same assays.
