Sodium Channel Blocker Library	128 compounds
Sodium channels conduct sodium ions (Na+) through a cell's plasma membrane that are the source of excitatory currents for the nervous system and muscle. Na channels 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). Dysfunction in voltage-gated sodium channels correlates with neurological and cardiac diseases, including epilepsy, myopathies, pain and cardiac arrhythmias. Sodium channel blockers are used in the treatment of cardiac arrhythmia, pain and convulsion. MCE offers a unique collection of 128 sodium channel blocker and antagonists, all of which have the identified inhibitory effect on sodium channels. MCE Sodium Channel Blocker Library can be used for neurological and cardiac diseases drug discovery and sodium channel research.
