Biological Activity

Acid-sensing ion channel 3 (ASIC3) channel blocker (IC50 values are 63 and 175 nM for homomeric rat and human ASIC3 channels). Also inhibits NaV1.8 and NaV1.2 channels (IC50 values are 55 and 114 nM respectively). Demonstrates analgesic properties against acid-induced and inflammatory pain.

Pain Poster

Peripheral sensitization is the reduction in the threshold of excitability of sensory neurons that results in an augmented response to a given external stimulus. This poster outlines the excitatory and inhibitory signaling pathways involved in modulation of peripheral sensitization. The role of ion channels, GPCRs, neurotrophins, and cytokines in sensory neurons are also described.
