PF-05089771

Research use only, not for human use.

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

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.

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) whilst 100 nM resulted in complete block.
