Structural Modifications Redirect Phenylpyrazole Ectoparasiticides from the Ion Channel Pore to an Allosteric Site on GABA Receptors
Phenylpyrazole ectoparasiticides, exemplified by fipronil, act as noncompetitive antagonists of arthropod GABA receptors by blocking the ion channel pore. Here, we investigated the molecular mechanism of the newer phenylpyrazole nicofluprole using Drosophila melanogaster. CRISPR/Cas9-mediated mutagenesis and pharmaco...
