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-B0551S

Doxapram-d₈	Inhibitor
Doxapram-d₈ is deuterated labeled Doxapram (HY-B0551). Doxapram is a respiratory stimulant. Doxapram increases breathing rate and depth by acting on the brain's respiratory centers and peripheral chemoreceptors.

Doxapram inhibits the Ca²⁺-activated potassium current (IC₅₀ ≈ 13 μM) and Ca²⁺-independent potassium current (IC₅₀ ≈ 20 μM) in type I cells of the carotid body. Doxapram significantly prolongs the effective refractory period of the atrium and has an anti-arrhythmic effect. Doxapram can be used for the study of respiratory depression such as post-anesthesia respiratory depression, chronic obstructive pulmonary disease and apnea of prematurity.
