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.
(Modifications: Arg-1 = N2-[4-(2-Naphthoylamino)phenylacetyl], Arg-4 = C-terminal (S)-2-methylbutylamide)
