Background:
A 887826 is a potent and voltage-dependent Nav1.8 sodium channel blocker. It blocked recombinant human Nav1.8 channels with an IC50 value of 11nM [1].
Voltage-gated sodium channels are important in the generation and propagation of action potential. At least 9 genes encode functional sodium channels, namely Nav1.1-Nav1.9. Nav1.8 is a TTX-resistant (TTX-R) sodium channel. Nav1.8 is highly localized on primary sensory afferent neurons. Nav1.8 is involved in the processing of nociceptive information.
-100 mV without prepulse did make a resting state for rat DRG neurons. Prepulse to -40 mV did make an inactivated state for channels. In rat DRG neurons in these two states, treatment with A 887826 at 1 μM significantly blocked TTXR Na+ currents. A 887826 blocked TTX-R Na+ currents with an IC50 value of 7.9 ± 0.2 nM (n= 5
