Biological Activity

[Description]:

PF-05089771 is a potent, state-dependent, subtype selective Nav1.7 inhibitor with IC50 of 11 nM, >1,000-fold selectivity over Nav1.3, 1.4 and Nav1.5, 1.8; interacts with the voltage-sensor domain (VSD) of domain IV, blocks all Nav1.7 splice variants with similar potency (5N11L, 5A11S, 5A11L and 5N11S, IC50s=11=33 nM); displays high selectivity over L-type calcium channels, KvLQT and hERG potassium channels; demonstrates in vivo efficacy in a mouse capsaicin-induced neurogenic flare model. Pain Phase 1 Discontinued

Subtype-Selective Small Molecule Inhibitors Reveal a Fundamental Role for Nav1.7 in Nociceptor Electrogenesis, Axonal Conduction and Presynaptic Release.

PLoS ONE 11(4) , e0152405, (2016)

Human genetic studies show that the voltage gated sodium channel 1.7 (Nav1.7) is a key molecular determinant of pain sensation. However, defining the Nav1.7 contribution to nociceptive signalling has ...
