A-803467能够抑制感觉神经元的自发和诱发动作电位。它具有镇痛作用。A-803467能够在体内减少脊髓背角神经元的放电。 小分子A-803467是一种有效的选择性Nav1.8钠离子通道阻滞剂。Nav1.8是一种抗河豚毒素（TTX-R）钠离子通道，通过在周围感觉神经元中传递疼痛刺激而产生痛觉；A-803467通过阻滞该通道，能够对多种模型产生不同程度的疼痛减轻作用。A-803467已被用于进一步探究Nav1.8在传递疼痛刺激中的作用. 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
