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.

Bepridil
0 ImagesSynonyms: CERM 1978 free base; Org 5730Bepridil (CERM 1978 (free base); Org 5730) is an orally active non-selective calcium channel antagonist with multi-ion channel blocking activity. Bepridil modulates Calmodulin, the 20S proteasome, T-type/L-type calcium channels, cardiac sodium channels, multiple potassium channels, γ-secretase, β-secretase, and mitoKATP/sarcKATP channels. Bepridil acts as a hydroxyl radical scavenger, regulates mitochondrial and intracellular calcium handling, and exerts antiarrhythmic, antianginal, and cardioprotective effects. Bepridil alters amyloid precursor protein processing, reduces β-amyloid and thalamic calcium levels, restores seladin-1/DHCR24 expression, and improves sensorimotor recovery after cerebral ischemia. Bepridil also exhibits potent inhibitory effects on SARS-CoV-2 replication. Bepridil is used in studies related to stable angina, arrhythmias, cerebral ischemia, Alzheimer's disease, and SARS-CoV-2 infection.

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.

Cereulide-13C6
0 ImagesCat. No.: HY-P3003SCAS No.: 1487375-69-8Cereulide-13C6 is a deuterated form of Cereulide. Cereulide is an orally active, blood-brain barrier-permeable emetic toxin. Cereulide acts as a potassium ionophore that inserts into membranes, forms complexes with K+, and transports K+ from the cytoplasm into the mitochondrial matrix. Cereulide disrupts the electrochemical gradient of the inner mitochondrial membrane, leading to mitochondrial swelling and dysfunction, uncoupling of oxidative phosphorylation, inhibition of ATP synthesis, ROS accumulation, and ultimately triggering apoptosis and autophagy. Cereulide exhibits multi-organ toxicity and can be used for research on emetic food poisoning.
