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.

    Aprikalim
    		Activator
    Aprikalim (RP 52891), a potassium channel opener (KCO), activates ATP-sensitive K+ (KATP) channels in guinea pig ventricular myocytes. Using patch-clamp techniques, it was found that aprikalim enhances KATP channel activity more effectively in Mg-NDP solution compared to standard solutions. In Mg-NDP solution, aprikalim reduced the sensitivity of KATP channels to ATP, increasing the concentration of ATP required to inhibit channel activity by half (K1) from 56 μM to 180 μM. However, this effect diminished over time. Aprikalim's ability to activate KATP channels in Mg-NDP solution suggests potential therapeutic implications in modulating cardiac excitability and may relate to changes in channel protein enzymatic activity under experimental conditions.
