Potassium Channel

Potassium Channels. K+ channels are membrane proteins that allow rapid and selective flow of K+ ions across the cell membrane, and thus generate electrical signals in cells. Voltage-gated K+ channels (Kv channels), present in all animal cells, open and close upon changes in the transmembrane potential.

Nigericin sodium salt
T309228643-80-3
Nigericin sodium salt is an antibiotic, an NLRP3 activator, and a cationic ion carrier. Nigericin sodium triggers the activation of the NALP3 inflammasome, which inhibits Golgi function and suppresses the growth of Gram-positive bacteria.

Levosimendan
T2530141505-33-1
Levosimendan (OR1259) is a calcium sensitizer used in the management of acutely decompensated congestive heart failure. It increases the sensitivity of the heart to calcium, thus increasing cardiac contractility without a rise in intracellular calcium. Levosimendan exerts its effect by increasing calcium sensitivity of myocytes by binding to cardiac troponin C in a calcium-dependent manner.
