Selective TRPA1 channel blocker that antagonizes AITC- and formalin-evoked calcium influx (IC50 values are 6.2 and 5.3 μM respectively). Does not block currents mediated by TRPV1, TRPV3, TRPV4, hERG or NaV1.2 channels. Inhibits AITC- and formalin-induced flinching in vivo.

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.
