产品描述:一种有效的Na+,K+-ATPase抑制剂Istaroxime, also known as PST-2744, is a positive inotropic agent that mediates its action through inhibition of sodium/potassium adenosine triphosphatase (Na+/K+ ATPase). Na+/K+ ATPase inhibition increases intracellular sodium levels, which reverses the driving force of the sodium/calcium exchanger, inhibiting calcium extrusion and possibly facilitating calcium entry. Additionally, Istaroxime increases intracellular calcium by improving the efficacy by which intracellular calcium triggers sarcoplasmic reticulum calcium release, and by accelerating the inactivation state of L-type calcium channels, which allow for calcium influx.
