Biological Activity

Rostafuroxin (PST2238) is potent, selective, orally active Na-K-ATPase inhibitor, displaces 3H ouabain from dog kidney Na+,K+-ATPase with IC50 of 1.5 nM; displays excellent selectivity over a panel of general and hormonal receptors, with exception of thromboxane A2 receptor (61% inhibition at 1 uM); abolishes ouabain-dependent increase in the Na-K pump rate in cultured renal cells, abolishes the increase in blood pressure and renal Na-K ATPase activity caused by ouabain in rats model of hypertension.
