Biological Activity for Rostafuroxin
Rostafuroxin is a Na+/K+ ATPase modulator. Inhibits the Normalizes renal Na+/K+ ATPase pump function in mutant adducin- and endogenous ouabain-dependent forms of hypertension. Reduces blood pressure in Milan hypertensive rats. Controls mania-like behaviors in Myshkin mice having a Na+/K+ ATPase α3 subunit mutation. Antagonizes the effects of Ouabain (Cat.No. 1076) on myogenic tone and Ca2+ signaling in rat hippocampal neurons.
