Antifeedant and Phytotoxic Activity of the Sesquiterpene p -Benzoquinone Perezone and Some of its Derivatives

Antifeedant and Phytotoxic Activity of the Sesquiterpene p -Benzoquinone Perezone and Some of its Derivatives The sesquiterpene p -benzoquinone perezone ( 1 ), isolated from Perezia adnata var . alamani (Asteraceae), and its non-natural derivatives isoperezone ( 2 ), dihydroperezone ( 3 ), dihydroisoperezone ( 4 ), and anilidoperezone ( 5 ) were tested as antifeedants against the herbivorous insects Spodoptera littoralis , Leptinotarsa decemlineata , and Myzus persicae . Compounds 1 – 5 exhibited strong antifeedant activity against L. decemlineata and M. persicae , and elicited a low response by S. littoralis . Antifeedant activity on L. decemlineata and M. persicae increased when the hydroxyl group at C-3 in perezone ( 1 ) was changed to C-6 to give isoperezone ( 2 ). The same effect was found with hydrogenation of the double bond of the alkyl chain of (1) to yield dihydroperezone ( 3 ). In contrast, hydrogenation of this double bond in isoperezone ( 2 ) to give dihydroisoperezone ( 4 ) led to a reduction in antifeedant activity. Determination of the phytotoxic activity of 1 – 5 revealed that 3 had a significant inhibition effect on Lactuca sativa radicle length growth. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Chemical Ecology Springer Journals
