Synthesis, potential anticonvulsant and antidepressant effects of 2-(5-methyl-2,3-dioxoindolin-1-yl)acetamide derivatives

AbstractA new series of 2-(5-methyl-2,3-dioxoindolin-1-yl)acetamide derivatives were synthesized and evaluated for their anticonvulsive activity in a pentylenetetrazole (PTZ)-evoked convulsion model and antidepressant activity in the forced swimming test (FST) model. Eleven synthesized compounds were found to be protective against PTZ-induced seizure and showed the anticonvulsant activity. In addition, four of the synthesized compounds (4l, 4m, 4p and 4q) showed potent antidepressant-like activity. Among these compounds, compound 4l was found to have the most potent antidepressant-like activity, and significantly reduced the duration of immobility time at 100mg/kg dose level when compared to the vehicle control, which is similar to the reference drug fluoxetine
