QAQ dichloride is a photoswitchable azobenzene-based open-channel blocker that inhibits voltage-gated sodium and potassium channels in its trans configuration. It is membrane-impermeant and selectively enters neurons that express endogenous import channels, making it a versatile light-sensitive probe for studying neuronal signaling and pain mechanisms in research settings.
Photoswitchable control of Nav and Kv channel activity.
Reversible channel block via photoisomerization.
Selective entry into neurons expressing import channels.
Applicable to acute and chronic pain signaling studies.
Stable dichloride salt form with defined storage recommendations.
