Anthranilic diamides is a class of insecticides target at ryanodine receptors (RyRs). To discover potent insecticides targeting at RyRs, a series of novel anthranilic diamides with a diacylhydrazine bridge were designed and synthesized. Their insecticidal activities were evaluated and a preliminary structure-activity relationship (SAR) was summarized. In particular, compound 5g exhibited good lethality against oriental armyworm (Mythimna separata) at a concentration of 5?mg/L. The calcium imaging experimental results indicated that the compound 5g can serve as effective insect Ca2+ level modulators by disrupting the cellular calcium homeostasis in Mythimna separata (Walker) and Spodoptera exigua (Hübner), which probably activated the RyRs on the ER membrane.
