IC50: 0.34 uM (Nav1.7)[1]
GNE-0439 is a novel Nav1.7-selective inhibitor with IC50 of 0.34 uM and inhibits Nav1.5 with an IC50 of 38.3 μM. GNE-0439 inhibits mutant N1742K channels (IC50=0.37 uM) in membrane potential assays. GNE-0439 possesses a carboxylic acid group, binds outside of the channel pore, and is unique compared with known selective VSD4 binders[1].
