Primarily used in medical research, it serves as a potent cardiac glycoside, aiding in the study of heart function and related diseases. Its ability to inhibit the sodium-potassium ATPase pump makes it valuable for investigating cellular ion transport mechanisms. Additionally, it is utilized in pharmacological studies to explore its effects on myocardial contractility and arrhythmias. Researchers also employ it to develop potential treatments for heart failure and other cardiovascular conditions. Its role in biochemical assays helps in understanding enzyme interactions and signaling pathways in cardiac cells.
