  Voltage-gated sodium channel NaV1.7 is a genetically validated target for pain. Identification of NaV1.7 inhibitors with all of the desired properties to develop as an oral therapeutic for pain has been a major challenge. Herein, we report systematic structure–activity relationship (SAR) studies carried out to identify novel sulfonamide derivatives as potent, selective, and state-dependent NaV1.7 inhibitors
