生物活性:
Mozavaptan (OPC-31260) is a benzazepine derivative and a potent, selective, competitive and orally active vasopressin V2 receptor antagonist with an IC50 of 14 nM. Mozavaptan shows ~85-fold selectivity for V2 receptor over V1 receptor (IC50 of 1.2 μM), and can antagonize the antidiuretic action of arginine vasopressin (AVP) in vivo. Mozavaptan has the potential for hyponatremia, syndrome of inappropriate antidiuretic hormone (SIADH), and congestive heart failure treatment.
体内研究:
Mozavaptan (OPC-31260; 1-30 mg/kg; oral administration; hydrated conscious rats) treatment dose-dependently increases urine flow and decreased urine osmolality.Mozavaptan (OPC-31260; 10-100 μg/kg; intravenous injection; male Sprague-Dawley rats) treatment inhibits the antidiuretic action of exogenously administered arginine vasopressin (AVP) in water-loaded, alcohol-anaesthetized rats in a dose-dependent manner.Animal Model:Hydrated conscious rats (300-350 g)
Dosage:1 mg/kg, 3 mg/kg, 10 mg/kg, 30 mg/kg
Administration:Oral administration
Result:Dose-dependently increased urine flow and decreased urine osmolality.
体外研究:
Mozavaptan (OPC-31260) inhibits AVP binding to binding to rat liver (V1 receptor) and kidney (V2 receptor) plasma membranes in a competitive manner and that it is about 100 times more selective for V2 receptors. Kd value for [3H]-AVP in rat liver is 1.1 nM; in rat kidney is 1.38 nM. The Kd of [3H]-AVP is reduced significantly in both rat liver and kidney in the presence of Mozavaptan (Kd of 2.47 nM and 5.51 nM for V1 receptor at the doses of 0.3 μM and 1 μM.respectively; Kd of 2.4 nM and 4.03 nM for V2 receptor at the doses of 0.3 μM and 1 μM.respectively).
