Description

General description

A highly potent, selective, competitive antagonist of P2X7 purinegic receptor (IC₅₀ = 18 nM and 40 nM, respectively as measured by Bz-ATP-stimulated Ca2+ flux). Does not affect other P2 receptors even at 10 µM concentrations. Blocks agonist-evoked IL-1b release (IC₅₀ = 156 nM) and pore formation (IC₅₀ = 92 nM) in differentiated human THP-1 cells. Also shown to reduce carrageenan and Freund′s adjuvant -induced thermal hyperalgesia (ED₅₀ = 38-54 mg/kg, i.p) and neuropathic pain induced by chronic constriction injury (CIC) of the sciatic nerve.
