Activation of tetrodotoxin-resistant sodium channels contributes to action potential electrogenesis in neurons. Antisense oligonucleotide studies directed against Na(v)1.8 have shown that this channel contributes to experimental inflammatory and neuropathic pain. We report here the discovery of A-803467, a sodium channel blocker that potently blocks(More)
Activation of sodium channels is essential to action potential generation and propagation. Recent genetic and pharmacological evidence indicates that activation of Na(v)1.8 channels contributes to chronic pain. Herein, we describe the identification of a novel series of structurally related pyridine derivatives as potent Na(v)1.8 channel blockers. A-887826(More)
