Biochem/physiol Actions

A71915 is a potent atrial natriuretic peptide A (ANP, NPPA) receptor (NPR1, ANP-A, ANPR-A, NPR-A) antagonist (pKi = 9.18 (Ki = 650 nM) by competitive binding against 300 nM rat ANP1-28 to human neuroblastoma NB-OK-1 cells; pA2 = 9.45 against rat ANP-induced cGMP production in NB-OK-1 cells). A71915 is reactive toward dog, human, mouse, rabbit, and rat species, and commonly employed both in cultures (1-10 μM) and in vivo for studying NPR-A-mediated responses.
Atrial natriuretic peptide A (ANP, NPPA) receptor (NPR1, ANPRA, NPRA) antagonist with in vitro and in vivo efficacy.
