A novel family of small molecule inhibitors of voltage-gated sodium channels (Na<sub>V</sub>s) based on the structure of batrachotoxin (BTX), a well-known channel agonist, is described. Protein mutagenesis and electrophysiology experiments reveal the binding site as the inner pore region of the channel, analogous to BTX, alkaloid toxins, and local anesthetics. Homology modeling of the eukaryotic channel based on recent crystallographic analyses of bacterial Na<sub>V</sub>s suggests a mechanism o ...[more]
