What is strophanthin used for?
Of particular interest is the heart-active substance strophanthin, which is used for heart problems such as cardiac arrhythmia and mild forms of heart failure. Strophanthus has positive effects on heart function by increasing the contractility of the heart muscle and regulating the heart rate. In summary, the mechanism of Strophanthin K revolves around its inhibition of the Na+/K+-ATPase pump, leading to increased intracellular sodium and calcium levels. This results in enhanced cardiac contractility and modulation of heart rhythm, making it a powerful agent in the management of specific heart conditions.
What is the history of strophanthus use?
The strophanthins, which we now know to be steroidal cardiac glycosides, were isolated from African plant sources (arrow poisons) in the late 19th century. By the 1880s, galenical preparations of strophanthus were commonly prescribed for cardiac patients as a substitute for digitalis. Strophanthus kombe is known for its historical use as a source of arrow poison. Today it is used medicinally to treat heart failure. The plant has been used for two extremes, ending a life and saving a life, so proper dosage is crucial when using this plant medicinally.Strophanthus is an herb. It has been used as an arrow poison in Africa. Strophanthus seeds are used to make medicine. Despite serious safety concerns, people take strophanthus for diabetes, heart problems, and high blood pressure, but there is no good scientific evidence to support these uses.
Is strophanthus a cardiac glycoside?
Strophanthus refers to a genus of plants from which strophanthin G, a fast-acting cardiac glycoside, is derived. It binds with high affinity to the α-subunit of the Na⁺/K⁺ pump, influencing cardiac function. The active principles from these plants and also from Strophanthus species are the cardiac glycosides, the aglycones (or genins) of which are steroids having a butyrolactone substituent in the 17-position. Examples are digoxygenin (41; R = OH) and digitoxygenin (41; R = H).
What are the active compounds in strophanthus?
Major bioactive compounds in Strophanthus kombe include: Strophanthin-K: a cardenolide glycoside that inhibits Na⁺/K⁺-ATPase, increasing intracellular calcium and improving heart muscle contractility. Ouabain-like substances: structurally similar to ouabain, these also modulate cardiac output but at lower potency. The active principles from these plants and also from Strophanthus species are the cardiac glycosides, the aglycones (or genins) of which are steroids having a butyrolactone substituent in the 17-position. Examples are digoxygenin (41; R = OH) and digitoxygenin (41; R = H).
