Characterization of a novel non-peptide vasopressin V1 receptor antagonist (OPC-21268) in the rat.


A non-peptide, orally effective, vasopressin (AVP) V1 receptor antagonist 1-(1-[4-(3-acetylaminopropoxy) benzoyl]-4-piperidyl)-3,4-dihydro-2(1H)-quinolinone (OPC-21268) has recently been described. This paper reports the in-vitro and in-vivo characterization of OPC-21268 binding to vasopressin receptors in rat liver and kidney. OPC-21268 caused a… (More)
