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.

Kv1.5-IN-1
0 ImagesCat. No.: HY-136805CAS No.: 1469902-72-4Kv1.5-IN-1 is a Kv1.5 channel inhibitor. Its target selectivity and pharmacodynamic effects were evaluated in an in vitro rat model. After the introduction of a methoxy group at the R5 position, Kv1.5-IN-1 showed inhibitory potency similar to that of the unsubstituted compound. Its IC50 value for hKv1.5 channels was 0.51 μM. Kv1.5-IN-1 exhibited a high degree of selectivity, nearly 2,600 times higher than compound Ik and 300 times higher than compound IId, indicating that it may be a safe inhibitor. Due to its good pharmacological behavior, Kv1.5-IN-1 deserves further pharmacodynamic and pharmacokinetic evaluation. These properties make Kv1.5-IN-1 a potential Kv1.5 channel inhibitor that may have application prospects in the treatment of related diseases.
