HC 067047 is a potent and selective TRPV4 antagonist. Reversibly inhibits currents through mouse, human and rat TRPV4 orthologs (IC50 values are 17, 48 and 133 nM respectively). Also inhibits the endogenous TRPV4-mediated response to 4α-PDH (IC50 = 22 nM). Selective for TRPV4 over TRPV1, TRPV2, TRPV3 and TRPM8 channels.

HC067047 (1µM) was used to demonstrate that TRPV4 channels contribute to pressure-induced membrane depolarization, intracellular [Ca2+] elevation, and constriction in neonatal pig renal preglomerular arteries.
HC067047 was used as a tool to demonstrate that eugenol activates TRPV4 currents in rat mesenteric artery endothelial cells using patch clamp electrophysiology.

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.
