Anticonvulsant activity of 2- and 3-aminobenzanilides
摘要:
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.
procedure for the thermo-promoted reactions of anthranil with different substrates was developed. The catalyst-free process affords various useful building blocks with good to moderate yields. This chemistry enables several step- and cost-effective approaches for biologically interesting molecules and provides an efficient platform for the investigation of untapped reactions at high temperature.
