Biological Activity for AP 811

AP 811 is a 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.

Investigation of NPR3 agonism in blood vessels.

AP811 is extremely unstable. Shipped at RT as powder, but need to be frozen upon arrival and made fresh each time.
