Biological Activity

A non-selective P2 purinergic antagonist. Blocks recombinant P2X1, P2X2, P2X3, P2X5 (IC50 = 1 - 2.6 μM), native P2Y2-like (IC50 ~ 0.9 mM), and recombinant P2Y4 (IC50 ~ 15 mM) receptors. Delays onset of calcium responses to mild hypoosmotic stress in cortical slices. iso-PPADS (Cat. No. 0683) also available.

P2X and P2Y Receptors Scientific Review

Written by Kenneth Jacobson, this review provides an overview of the different subtypes and structures of the P2 receptor families, as well as the pharmacological probes used to study them; compounds available from Tocris are listed.

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.
