Design,Synthesis, Biological Evaluation and SARs of Anthranilic Diamide Derivatives Containing Pyrrole Moieties

In order to find a new variety of ryanodine receptor(RyR) regulator with greater biological activity, a series of anthranilic diamide derivatives possessing pyrrole structure was designed and synthesized in this study. The pyrrole derivatives were evaluated for their insecticidal activity against Mythimna separata and Plutella xylostella. As indicated by the preliminary biological activities, compounds 12h-12j and 12l-12n exhibited a remarkable insecticidal activity against M. separata at 0.25 mg/L. Compared to control chlorantraniliprole, compound 12j exhibited more excellent insecticidal activity at 0.1 mg/L. Meanwhile, compounds 12c, 12h, 12i, 12j, 12l, and 12m were selected to test the insecticidal activity against P. xylostella, which led to the desirable insecticidal activity at 1×10^-3 mg/L. Notably, compound 12l demonstrated 47% insecticidal activity at 5×10^-6mg/L over the control. In addition, the biological mechanism of action of compound 12j was investigated by means of insect electrophysiology experiment.
