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.

A2764 dihydrochloride
0 ImagesA2764 dihydrochloride is a highly selective inhibitor of TRESK (TWIK-related spinal cord K+ channel, K2P18.1), which has moderate inhibitory effects on TREK-1 and TALK-1.

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.

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.
