The general structure of a cardiac glycoside consists of a steroid molecule attached to a sugar and an R group. [4] The steroid nucleus consists of four fused rings to which other functional groups such as methyl, hydroxyl, and aldehyde groups can be attached to influence the overall molecule's biological activity.

Digoxin is in the cardiac glycoside family of medications. [4] It was first isolated in 1930 from the foxglove plant, Digitalis lanata. [7] [8] It is on the World Health Organization's List of Essential Medicines. [9] In 2021, it was the 241st most commonly prescribed medication in the United States, with more than 1 million prescriptions. [10 ...
Salicin, a glycoside related to aspirin Chemical structure of oleandrin, a cardiac glycoside. In chemistry, a glycoside / ˈ ɡ l aɪ k ə s aɪ d / is a molecule in which a sugar is bound to another functional group via a glycosidic bond. Glycosides play numerous important roles in living organisms. Many plants store chemicals in the form of ...
Digitoxin is a cardiac glycoside used for the treatment of heart failure and certain kinds of heart arrhythmia. It is a phytosteroid and is similar in structure and effects to digoxin, though the effects are longer-lasting. Unlike digoxin, which is eliminated from the body via the kidneys, it is eliminated via the liver, and so can be used in ...
Digitalis purpurea drawings by Franz Köhler. Depending on the species, the digitalis plant may contain several deadly physiological and chemically related cardiac and steroidal glycosides. Thus, the digitalis plants have earned several, more sinister, names: dead man's bells and witch's gloves. The toxins can be absorbed via the skin [39] or ...
Mechanism of action of cardiac glycosides (Digitalis): inhibition of Na+/K+ ATPase. Cardiac glycosides like digoxin, primarily inhibit the sodium-potassium pump (Na+/K+ ATPase), an important protein located on the surface of cardiomyocytes (cardiac muscle cells).
Digitalis ciliata, commonly called hairy foxglove is a member of the genus Digitalis. [1] It has thimble-shaped, yellow to cream-colored flowers produced on perennial plants with evergreen foliage. It is native to the Caucasus and is grown as an ornamental plant in other parts of the world. The species name is derived from the fine hairs that ...
Cardenolide glycosides are often toxic; specifically, they are heart-arresting. Cardenolides are toxic to animals through inhibition of the enzyme Na + /K + -ATPase , which is responsible for maintaining the sodium and potassium ion gradients across the cell membranes.
