sulfonamides as potent Nav1.7 inhibitors with excellent selectivity against the Nav1.5 isoform, which is expressed in the heart muscle. Elaboration of initial lead compound 3d afforded exemplar 13, which featured attractive physicochemical properties, outstanding lipophilic ligand efficiency and pharmacological selectivity against Nav1.5 exceeding 1000-fold. Key structure-activityrelationships associated
hNav1.7 small molecular inhibitors have attracted lots of attention by its unique analgesic effect. Herein, we report the design and synthesis of a novel series of tetrahydropyridine analogs as hNav1.7 inhibitors for analgesia. Detail structural-activity relationship (SAR) studies were undertaken towards improving hNav1.7 activity, in vitro ADME, and in vivo PK profiles. These efforts resulted in the
