Selective TRPV4 antagonist (IC50 values are 2.3, 3.2 and 5.9 μM for hTRPV4, rTRPV4 and mTRPV4 receptors respectively). Displays selectivity for TRPV4 over other TRP channels (IC50 values are 2.3, >30, >30 and >100 μM for TRPV4, TRPV3, TRPM8 and TRPV1 respectively). Blocks TRPV4-mediated arteriole vasodilation and increases myogenic tone ex 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.
