Dinotefuran is an orally active and competitive inhibitor and insecticide targeting insect nicotinic acetylcholine receptors (nAChRs). Dinotefuran blocks neural signaling and induces neural dysfunction in insects. Dinotefuran binds to [3H]epibatidine in the neural cord membrane of American cockroach with an IC50 of 890 nM and to [3H]α-bungarotoxin with an IC50 of 36.1 µM. Dinotefuran exhibits knockdown activity (KD50=0.351 nmol/g) and lethal activity (LD50=0.173 nmol/g) against German cockroach. Dinotefuran is mainly used for agricultural pest control, such as field control of piercing-sucking and chewing insects (e.g., aphids, planthoppers), while its environmental toxicological effects (e.g., oxidative stress and reproductive neurotoxicity on earthworms) are also a research focus to assess ecological risks[1][2][3].
