Sodium channels are integral membrane proteins that form ion channels, conducting sodium ions (Na+) through a cell's plasma membrane. They are classified according to the trigger that opens the channel for such ions, i.e. either a voltage-change (Voltage-gated, voltage-sensitive, or voltage-dependent sodium channel also called VGSCs or Nav channel) or a binding of a substance (a ligand) to the channel (ligand-gated sodium channels). In excitable cells such as neurons, myocytes, and certain types of glia, sodium channels are responsible for the rising phase of action potentials. Voltage-gated Na+ channels can exist in any of three distinct states: deactivated (closed), activated (open), or inactivated (closed). Ligand-gated sodium channels are activated by binding of a ligand instead of a change in membrane potential.

  • HY-A0236
    Aprindine
    		Inhibitor 98.43%
    Aprindine is an Ib-class anti-arrhythmic agent.

Aprindine significantly inhibits delayed potassium currents, which helps to prolong the atrial effective refractory period (AERP) and inhibit the occurrence of atrial fibrillation. Aprindine can also regulate intracellular calcium ion concentration by inhibiting Na+/Ca2+ exchange current (INCX), thereby further stabilizing cardiac electrical activity. Aprindine can be used for the study of atrial fibrillation (AF) and ventricular arrhythmias.
