Abstract
Fipronil, which targets on GABAA receptors (GABAARs), is the first phenylpyrazole insecticide widely used in crops protection and public hygiene. However, its high toxicity on fishes deeply limited its applications. In the present study, a series of computational methods including the homology modeling, docking and molecular dynamics simulation studies were integrated to explore the binding difference of fipronil with GABAARs from fruitfly and zebrafish systems. It was found that, in zebrafish system, the H-bond between 6'Thr and fipronil exerted key effects on the recognition of fipronil, which was absent in fruitfly system. On the other hand, in fruitfly system, strong electrostatic interaction between 2'Ala and fipronil was favorable to the binding of fipronil, while was detrimental to the binding in zebrafish system. These findings marked the binding difference of fipronil with different GABAARs, which might be helpful in designing selective insecticides against pests instead of fishes.
