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.

    Trimebutine
    		Inhibitor 99.42%
    Trimebutine is a multi-target inhibitor and opioid receptor agonist with antimuscarinic activity. Trimebutine inhibits L-type Ca2+ channels and large-conductance calcium-activated potassium channels (BKCa channels), thereby inhibiting extracellular calcium influx and potassium ion efflux. Trimebutine also targets Toll-like receptors, inhibits Toll-like receptor 2/4/7/8/9 signals, and inhibits LPS-induced IRAK1 activation, as well as ERK1/2, JNK and NF-κB activation, thereby exerting anti-inflammatory effects. Trimebutine also induces tumor cell apoptosis by inhibiting the AKT/ERK pathway. Trimebutine also inhibits excessive contraction of smooth muscle and can be used in the study of gastrointestinal disorders such as irritable bowel syndrome (IBS).
