Description | Fuscoside (OPC-21268) is a non-peptide arginine vasopressin (AVP) receptor VI antagonist with an IC50 value of 0.4 μM[2]. |
Targets&IC50 | V1 (human):8800 nM, V1 (rat):25 nM |
In vitro | Fuscoside (OPC-21268) can replace 50% of the specific AVP binding concentration (IC50), including 0.4 μM for VI receptors and 100 μM for V2 receptors; at the same time, the inhibition constant (Ki) of Fuscoside (OPC-21268) for V1 receptors is 0.14 μM[2]. |
In vivo | METHODS: OPC-21268 was injected intravenously into dogs and rats at doses of 0.3, 1.0, and 3.0 mg/kg to study its antagonistic effects on arginine vasopressin (AVP)-induced vasoconstrictor responses in spinally anesthetized dogs. RESULTS OPC-21268 produced a right-parallel shift of the AVP dose-response curve in a dose-dependent manner; doses of OPC-21268 were similar to those that inhibited AVP-induced vasoconstrictor responses in rats; OPC-21268 acted as a V1-AVP receptor antagonist in peripheral resistance vessels of dogs and rats.
