QAQ
QAQ dichloride dichloride, a photoswitchable voltage-gated Nav and Kv channels blocker, blocks channels in its trans form (of the azobenzene photoswitch), but not in its cis form. QAQ dichloride dichloride is membrane-impermeant and only infiltrates pain-sensing neurons that express endogenous import channels. QAQ dichloride dichloride acts as a light-sensitive analgesic and can be used for studying of signaling mechanisms in acute and chronic pain.

Target: voltage-gated Nav and Kv channels
QAQ dichloride dichloride (100 μM) does not cross the membrane and can be injected into cells through a micropipette to photosensitize a single cell and afford subcellular control of action potential propagation. It blocks Shaker-IR current in the trans configuration and unblocks it in the cis configuration[1]. QAQ dichloride dichloride can be used to develop red-shifted derivatives of QAQ dichloride, powerful doubly charged photochromic blockers.These derivatives allow for remote control of Kv and Nav channel conductance with light and offer the opportunity to silence neuronal activity reversibly[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
