Description: PF-05089771 is a Selective Nav1.7 Inhibitor (IC50 = 11 nM) that interacts with the voltage-sensor domain (VSD) of domain IV. PF-05089771 exhibits a slow onset of block that is depolarization and concentration dependent, with a similarly slow recovery from block. Human hereditary gain- or loss-of-pain disorders have demonstrated an essential role of Nav1.7 sodium channels in the sensation of pain, thus making this channel an attractive target for new pain therapies.
