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.

Propafenone
0 ImagesSynonyms: SA-79Propafenone (SA-79), a sodium-channel blocker, acts an antiarrhythmic agent. Propafenone also has high affinity for the β receptor (IC50=32 nM). Propafenone blocks the transient outward current (Ito) and the sustained delayed rectifier K current (Isus) with IC50 values of 4.9 μm and 8.6 μm, respectively. Propafenone suppresses esophageal cancer proliferation through inducing mitochondrial dysfunction and induce apoptosis.
-
AZD4144
0 ImagesAZD4144 is an orally active NLRP3 inhibitor (EC50: 0.082 μM). AZD4144 effectively inhibits the release of IL-1β when NLRP3 is overactivated, exerting an anti-inflammatory effect. AZD4144 has low inhibitory effect on hERG and low cardiotoxicity. AZD4144 has the potential to study diseases and conditions associated with NLRP3 inflammasome activation.

Indapamide
0 ImagesIndapamide is an orally active sulphonamide diuretic agent, that can reduce blood pressure by decreasing vascular reactivity and peripheral vascular resistance. Indapamide is also can reduce left ventricular hypertrophy.
-
Glipizide
0 ImagesSynonyms: CP 28720; K 4024Glipizide (CP 2872; K 4024)?a potent, orally active and sulfonylurea class anti-diabetic agent and can be used for type 2?diabetes mellitus research but not type 1. Glipizide acts by partially blocking ATP-sensitive potassium?(KATP) channels among β cells of pancreatic islets of Langerhans.

L-Palmitoylcarnitine-d3 hydrochloride
0 ImagesL-Palmitoylcarnitine-d3 hydrochloride is the deuterium labeled L-Palmitoylcarnitine hydrochloride. L-Palmitoylcarnitine hydrochloride, a long-chain acylcarnitine and a fatty acid metabolite, accumulates in the sarcolemma and deranges the membrane lipid environment during ischaemia. L-Palmitoylcarnitine hydrochloride inhibits KATP channel activity, without affecting the single channel conductance, through interaction with Kir6.2.

Sodium α-ketoisocaproate
0 ImagesSynonyms: Sodium 4-methyl-2-oxopentanoate; 2-Ketoisocaproic acid sodium saltSodium α-ketoisocaproate (Sodium 4-methyl-2-oxopentanoate) is an insulin secretagogue. Sodium α-ketoisocaproate undergoes transamination catalyzed by BCAT and BCATm to produce α-ketoglutarate and leucine; it also binds to the SUR1 site to inhibit KATP channel activity, but does not directly affect the Kir6.2 subunit. 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.
