Rostafuroxin

Rostafuroxin is a digitoxigenin analog that has been shown to lower blood pressure in an animal model of hypertension.[1] It modulates the effects of the enzyme Na+/K+-ATPase,[1] which maintains sodium and potassium ion gradients across plasma membranes. Rostafuroxin is being studied in clinical trials for the treatment of essential hypertension.[2][3]
