Anticonvulsant activity of 2- and 3-aminobenzanilides.
A series of 2- and 3-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 maximal electroshock (MES) and pentylenetetrazole and in the rotorod assay for neurologic deficit. The 3-aminobenzanilide derived from 2,6-dimethylaniline, 21, was the most potent anti-MES compound, with an ED50 of 13.48 mg/kg and a protective index of 21.11 (PI = TD50/ED50). The activity profile for 21 compares favorably with that for phenobarbital and phenytoin.
