Electrochemical reduction potential correlation of some insect antifeedant potent 2-phenothiazinyl chalcones
نویسندگان
چکیده
A series containing twelve substituted styryl 2-phenothiazenyl ketones have been synthesized. The electrochemical potentials of carbonyl and vinyl groups were measured. These potentials are correlated with Hammett substituent constants, F and R parameters. From the results of statistical analyses, the effects of substituent on the group reduction potentials have been discussed. The insect antifeedant activities of these chalcones have been studied using 4 instar larvae Achoea Janata L with castor leaf discs.

Electrochemical Synthesis of Dihydrobenzofurans and Evaluation of Their Insect Antifeedant Activities.
Electrochemically synthesized dihydrobenzofurans were evaluated for their insect antifeedant activities against phytophagous insects. They were prepared through the coupling reactions of various alkenes with a phenoxy cation generated by oxidation near the cathode in the electrolytic reaction. The insect antifeedant activities of these synthetic dihydrobenzofurans were evaluated in the common c...
متن کاملPotent limonoid insect antifeedant from Melia azedarach.
Systematic fractionation of a fruit extract from Argentine Melia azedarach L., which was monitored by an insect antifeedant bioassay, led to the isolation of meliartenin, a limonoid antifeedant, which existed as a mixture of two interchangeable isomers. At 4 microg/cm2 and 1 microg/cm2, the isomeric mixture was as active as azadirachtin in strongly inhibiting the larval feeding of Epilachna pae...

The insect antifeedant activities of pterocarpans and a sesquiterpene alcohol from the dichloromethane extract of Pterocarpus macrocarpus Kruz. (Leguminosae) were evaluated against the common cutworm, Spodoptera litura F. (Noctuidae), and the subterranean termite, Reticulitermes speratus (Kolbe)(Rhinotermitidae). Three pterocarpans, (-)-homopterocarpin (1), (-)-pterocarpin (2), and (-)-hydroxyh...
متن کاملAntifeedant activity and high mortality in the pea aphid Acyrthosiphon pisum (Hemiptera: Aphidae) induced by biostable insect kinin analogs.
The insect kinins are multifunctional neuropeptides found in a variety of arthropod species, including the pea aphid Acyrthosiphon pisum (Hemiptera: Aphidae). A series of biostable insect kinin analogs based on the shared C-terminal pentapeptide core region were fed in solutions of artificial diet to the pea aphid over a period of 3 days and evaluated for antifeedant and aphicidal activity. The...
