Di-4-ANEPPS [CAS 90134-00-2]

Di-4-ANEPPS is a voltage-sensitive dye that acts on voltage-gated ion channels (such as sodium channels) and inhibits sodium current, significantly reducing sodium current density, although specific values like IC50 remain unclear. It mainly binds to the voltage-sensitive regions on the cell membrane, changing its fluorescence properties to reflect membrane potential changes and thus affecting the function of ion channels to exert its activity. This substance can be used in cardiovascular research, such as the electrophysiology of cardiomyocytes, myocardial ischemia, and the effects of drugs on cardiomyocytes. It is of great value in evaluating drug cardiotoxicity and exploring the mechanisms of arrhythmias[1][2].
