PF-04856264 is a potent, selective inhibitor of the human Nav1.7 voltage gated sodium channel (IC50 = 28 nM). The voltage-gated sodium channel NaV1.7 is preferentially expressed in peripheral somatic and visceral sensory neurons, olfactory sensory neurons and sympathetic ganglion neurons. NaV1.7 is a major contributor to pain signalling in humans, and homology modelling based on crystal structures of ion channels suggests an atomic-level structural basis for the altered gating of mutant NaV1.7 that causes pain.
