(omega- aminoalkoxy )stilbene derivatives has been synthesized and screened for anticonvulsantactivity. The effect of structural modification of these molecules on the activities has been systematically examined. Potent anticonvulsantactivity was displayed by 2-[4-(4-methyl-1 piperazinyl)butoxy]stilbene (20) and some2-[4-(3-alkoxy-1-piperidino)butoxy]stilbene derivatives (21, 37, 38, and 40), as determined
