Biological Activity

High affinity, selective ANP clearance receptor (NPR3) antagonist (Ki = 0.45 nM). Exhibits >20,000-fold selectivity for NPR3 over NPR1. Inhibits ANP-stimulated Na+/K+ pump activity in rabbit ventricular cardiomyocytes in vitro. Also blocks proliferation of rodent neonatal cardiomyocytes seen at low ANP concentrations in vitro.

Technical Data

Soluble to 1 mg/ml in 10% ethanol / water
Store at -20°C
