A 438079 hydrochloride
Biological Activity for A 438079 hydrochloride
A 438079 hydrochloride is a competitive P2X7 receptor antagonist (pIC50 = 6.9 for the inhibition of Ca2+ influx in the human recombinant P2X7 cell line). Devoid of activity at other P2 receptors (IC50 >> 10 μM). Possesses antinociceptive activity in models of neuropathic pain in vivo. Inhibits methamphetamine-induced microglial migration and phagocytosis in vitro.

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.
