Purity ~95% (HPLC). A membrane-impermeant Na+, K+, and Ca2+ channel blocker that is structurally composed of two azo-linked QX-314 type quaternary amines. Both QX-314 and QAQ are shown to selectively target excitability of nociceptor neurons via TRPV1-dependent cellular uptake. Unlike QX-314, the channel blocking activity of QAQ can be quickly switched on and off via optical cis-to-trans (500nM) and trans-to-cis (320nM) isomerization. Its efficacy as a pain-selective, photochromic anesthetic has been demonstrated in rats in vivo. QAQ cellular uptake can also be achieved by ATP-activated P2X7 receptor.
