A-967079 (E1890-GRP)

A-967079 is a selective antagonist of TRPA1 receptor with IC50 values of 67 nM and 289 nM at human and rat TRPA1 receptors, respectively. A-967079 decreases the responses of wide dynamic range (WDR), and nociceptive specific (NS) neurons following noxious pinch stimulation and high-intensity mechanical stimulation in rats. It demonstrates strong penetration into the central nervous system (CNS).
