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.

  • HY-110082
    Quinine (hydrochloride)
    Inhibitor 99.83%
    Quinine hydrochloride is an alkaloid extracted from cinchona bark and exhibits oral activity, acting as a potassium channel inhibitor. Quinine hydrochloride modulates the tolerance of red blood cells and presents dose-dependent toxicity and embryonic effects. Quinine hydrochloride is a typical hemolysin that directly lyses red blood cells, with cellular components of red blood cell membranes as its action targets. Quinine hydrochloride disrupts red blood cell membranes and induces hemolysis at high concentrations, while merely weakening the anti-hemolytic capacity of red blood cells at low concentrations. Quinine hydrochloride continuously reduces red blood cell tolerance after in vivo administration, and high doses can also alter blood cell counts. Quinine hydrochloride can be applied to researches related to red blood cell hemolysis, cancer and malaria.
