Digitoxigenin
Digitoxigenin is a steroid derivative commonly found in various plants, especially the foxglove plant (Digitalis purpurea). Digitoxigenin has unique chemical properties that make it an important precursor for the synthesis of cardiac glycosides, a group of dr-ugs used to improve heart failure and certain types of arrhythmias. It works by inhibiting the sodium potassium ATPase pump, thereby increasing the force and efficiency of cardiac contractions.
