Potassium Channel
KcsA
Potassium channels are the most widely distributed type of ion channel and are found in virtually all living organisms. They form potassium-selective pores that span cell membranes. Potassium channels are found in most cell types and control a wide variety of cell functions. Potassium channels function to conduct potassium ions down their electrochemical gradient, doing so both rapidly and selectively. Biologically, these channels act to set or reset the resting potential in many cells. In excitable cells, such asneurons, the delayed counterflow of potassium ions shapes the action potential. By contributing to the regulation of the action potential duration in cardiac muscle, malfunction of potassium channels may cause life-threatening arrhythmias. Potassium channels may also be involved in maintaining vascular tone.

Aprindine hydrochloride
0 ImagesAprindine hydrochloride is an Ib-class anti-arrhythmic agent. Aprindine hydrochloride mainly exerts its effect by blocking sodium channels (INa), thereby reducing the excitability and conduction velocity of cardiac muscle cells. Aprindine hydrochloride significantly inhibits delayed potassium currents, which helps to prolong the atrial effective refractory period (AERP) and inhibit the occurrence of atrial fibrillation. Aprindine hydrochloride can also regulate intracellular calcium ion concentration by inhibiting Na+/Ca2+ exchange current (INCX), thereby further stabilizing cardiac electrical activity. Aprindine hydrochloride can be used for the study of atrial fibrillation (AF) and ventricular arrhythmias.

Noribogaine hydrochloride
0 ImagesNoribogaine hydrochloride is an orally active, blood-brain barrier permeable SERT inhibitor (IC50=50-300 nM) and hERG channel blocker. Noribogaine hydrochloride enhances serotonergic transmission, activates the κ-opioid receptor (OPRK) G protein signaling pathway and inhibits β-arrestin recruitment. Meanwhile, Noribogaine hydrochloride blocks the μ-opioid receptor (OPRM) signaling pathway as well as ion channels associated with cardiac repolarization. Noribogaine hydrochloride induces neuritogenesis, upregulates GDNF mRNA expression, and modulates opioid tolerance. Noribogaine hydrochloride reduces alcohol-seeking behavior in experimental animals, and is widely used in studies related to depression, addiction, alcoholism, and cardiotoxicity.
