| Hazard Information | Back Directory | [Description]
Rostafuroxin potently inhibits binding of endogenous ouabain to the Na+/K+ ATPase (IC50 = 1.7 μM) through the Src-epidermal growth factor receptor (EGFR)-dependent signaling pathway. This blocks the ouabain-dependent increase in Na+/K+ ATPase activity. In cultured renal cells where the Na+/K+ ATPase is upregulated or has increased activity, rostafuroxin normalizes mRNA levels and Na+/K+ ATPase activity. At very low doses (1 and 10 μg/kg for 5-6 weeks) in Milan-hypertensive rats, it decreased the development of hypertension. In a Phase II clinical study, rostafuroxin did not reduce blood pressure in human patients at doses of 0.05-5.0 mg/d. | [Uses]
(3β,5β,14β)-21,23-Epoxy-24-Norchola-20,22-diene-3,14,17-triol is used as a receptor blocker in the treatment of hypertension. | [in vitro]
at molecular level, in the kidney, rostafuroxin antagonizes eo by triggering of the src-epidermal growth factor receptor (egfr)-dependent signaling pathway leading to renal na+-k+ pump, and erk tyrosine phosphorylation and activation. in the vasculature, it normalizes the increased myogenic tone caused by nanomolar ouabain [1]. | [in vivo]
rostafuroxin reduces blood pressure without affecting heart rate, and restores the normal activity of the renal na+-k+-atpase in mhs rats when orally treated at doses from 1 to 100 μg/kg/day. similarly, nua rats have their blood pressure normalized by rostafuroxin [1]. | [IC 50]
