Cat.No. 5498 - AP 811 | N2-[4-(2-Naphthoylamino)phenylacetyl]-Arg-Ile-Asp-Arg-(S)-2-methylbutylamide | CAS No. 124833-45-0
Description: High affinity, selective NPR3 antagonist

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.
