GNE-616 is a highly potent, metabolically stable, orally bioavailable, and subtype-selective Nav1.7 inhibitor (Ki: 0.79 nM, Kd: 0.38 nM for hNav1.7) for the treatment of chronic pain.
Potent rat Nav1.7, human Nav1.4 and rat Nav1.6 channel activator (EC50 values are 7, 10 and 47 nM, respectively). Exhibits minimal activation at mammalian Nav1.2, Nav1.3 and Nav1.5 (EC50 values >3 μM). Inhibits fast inactivation on all channels. Increases
