Biological Activity for GX 201

GX 201 is a potent and selective Nav1.7 blocker (IC50 = 3.2 nM). Exhibits 10x selectivity for Nav1.7 over Nav1.1, Nav1.2, and Nav1.6 channels. Displays prolonged residency time on the Nav1.7 channel. Chronic dosing increases compound potency ~10-fold and provides efficacy that persists after the compound has cleared from plasma. Suppresses neuropathic pain in a mouse diabetic neuropathy model. Analgesic.
