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.

Besipirdine hydrochloride
0 ImagesCat. No.: HY-14607CAS No.: 130953-69-4Synonyms: HP 749Besipirdine (hydrochloride) is a potassium channel blocker with cholinergic and adrenergic activity. The cholinergic activity of Besipirdine (hydrochloride) involves stimulating phosphatidylinositol turnover and reducing potassium currents. The adrenergic activity of Besipirdine (hydrochloride) involves stimulating norepinephrine release, which is attributed to the inhibition of presynaptic α2-adrenergic receptors and the inhibition of norepinephrine uptake. Besipirdine (hydrochloride) may be used in research for Alzheimer's disease.
