A subtype-selective, competitive and reversible P2X1 receptor antagonist. Displays IC50 values of 0.21, 28.9, > 50 and > 100 μM for human P2X1, P2X3, P2X2, and P2X4-mediated responses respectively. Selective over adrenoceptors, histamine and P2Y receptors. Also selectively inhibits the α-subunit of Go/i (EC50 ~300 nM). Also inhibits DNA-binding activity of HMGA2 (IC50 = 10.63 μM).

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.
