PF-05089771 free base

Research use only, not for human use.

PF-05089771 free base is a potent, subtype selective Nav1.7 inhibitor with IC50 of 11 nM.

PF-05089771 free base is a potent, subtype selective Nav1.7 inhibitor with IC50 of 11 nM, shows no activity against Nav 1.5 and >10-fold selectivity over other Nav isoforms; specifically interacts with the voltage-sensor domain (VSD4); blocks the majority of TTX-S current (75%) at 30 nM in human DRG neurons (IC50=8.4 nM); exhibits action potentials in spinal slice electrophysiology recordings, mouse and human DRG neurons, demonstrates in vivo efficacy mouse capsaicin-induced neurogenic flare model.

PF-05089771 is determined to be more than 1000-fold selective over tetrodotoxin-resistant (TTX-R) Nav1.5 and Nav1.8 channels (IC50s >10 μM) and exhibited a range of selectivity over TTX-sensitive (TTX-S) channels (10-fold for Nav1.2 to 900-fold for Nav1.3 and Nav1.4).PF-05089771 (30 nM) blocks the majority of TTX-S current (75.5 ± 10.5%, n = 5, Fig 5D) whilst 100 nM resulted in complete block.
