Sodium Channel
Na channels; Na+ channels
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.

AFD-21 maleate
0 ImagesCat. No.: HY-136995CAS No.: 99465-44-8AFD-21 maleate is a drug with antiarrhythmic activity. AFD-21 maleate inhibits sodium channels by binding to sodium channels in an inactive state, with both use-dependent and voltage-dependent effects. The unbinding rate of AFD-21 maleate is similar to that of Class I antiarrhythmic drugs with moderate kinetics. AFD-21 maleate can cause a slight prolongation of the action potential duration and significantly reduce the maximum rise rate of the action potential at certain concentrations. AFD-21 maleate also showed use-dependent blocking effects as stimulation frequency increased.
