Abstract
The phytochemistry of the genus Piper (Piperaceae) has been widely studied due to the biological properties of amides from these plants. In this work, we have synthesized and evaluated the toxic effect of 11 amides against the fall armyworm Spodoptera frugiperda larvae. The naturally occurring piperine was also evaluated. The most active amide was N-[3-(3′,4′- methylenedioxyphenyl)-2-(E)-propenoyl]piperidine with a LD50 of 1.07 μg mg-1 larvae. This amide was also evaluated by ingestion. © 2006 Verlag der Zeitschrift für Naturforschung.
