General description

A-803467 inhibits spontaneous and evoked action potentials in sensory neurons. It exhibits antinociceptive effects. A-803467 decreases the firing in spinal dorsal horn neurons in vivo.
The small molecule A-803467 is a potent and selective Nav1.8 sodium channel blocker. Nav1.8 is a tetrodotoxin-resistant (TTX-R) sodium channel that contributes to pain sensation by transmitting pain stimuli in peripheral sensory neurons; blockage of this channel by A-803467 reduces pain with varying effectiveness in a number of different models. A-803467 has been used to further understand the role of Nav1.8 in transmitting pain stimuli and also can be used as an analgesic.

Biochem/physiol Actions

A-803467 blocks Nav1.8 in both half-maximal inactive and resting states with an IC50 of 8 nM and IC50 of 79 nM, respectively. A-803467 is over 100-fold more selective vs. human Nav1.2, 1.3, 1.5 and 1.7.
