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.

Eicosatetraynoic acid
0 ImagesEicosatetraynoic acid (ETYA) is a non-metabolizable analog of Arachidonic acid (HY-109590) and also an inhibitor of the lipoxygenase (LOX)/cyclooxygenase (COX) pathway (ID50 = 8 μM and 4 μM). Eicosatetraynoic acid acts as a suicide substrate to inhibit the production of inflammatory mediators such as leukotrienes and prostaglandins. Eicosatetraynoic acid acts directly on cell membranes and membrane proteins to exert a wide range of effects, including blocking potassium channels, increasing cell membrane fluidity, elevating intracellular calcium levels, inhibiting DNA synthesis in tumor cells, inducing differentiation of certain cells, and specifically inhibiting the assembly and replication of orthopoxviruses. Eicosatetraynoic acid alleviates acute lung injury induced by chemicals such as phosgene.

Sodium α-ketoisocaproate regulates Ca2+ influx. Sodium α-ketoisocaproate exerts insulinotropic activity in pancreatic islets and intact mouse pancreata with sufficient BCATm expression. Sodium α-ketoisocaproate can be used in research related to type 2 diabetes.
