Biological Activity

Description Tolvaptan (OPC-41061) is an orally effective nonpeptide arginine vasopressin V2 receptor antagonist with IC50 of 3 nM, used to treat hyponatremia.
Targets
vasopressin receptor 2 [4]
3 nM
In vitro
In vitro Tolvaptan blocks the binding of [(3)H]AVP to human V(2) receptors with 29-fold greater selectivity than that for V(1a) receptors, and showed no inhibition of V(1b) receptors. Tolvaptan inhibits not only the binding of [(3)H]AVP but also the AVP-induced production of cyclic AMP in human V(2)-receptor-expressing HeLa cells. Tolvaptan shows marked aquaresis in healthy and diseased animals. [1] Tolvaptan causes a concentration-dependent inhibition of arginine vasopressin-induced cAMP production with an apparent IC(50) of 0.1 nM in autosomal dominant polycystic kidney disease (ADPKD) cells. Tolvaptan inhibits AVP-induced ERK signaling and cell proliferation. Tolvaptan inhibits AVP-induced Cl(-) secretion and decreases in vitro cyst growth of ADPKD cells cultured within a three-dimensional collagen matrix. [2]
In Vivo
In vivo Tolvaptan improves hyponatremia, resulting in the prevention of death, and improves organ water retention in rat models with acute and chronic hyponatremia. Tolvaptan reduces cardiac preload without unfavorable effects on renal functions, systemic hemodynamics, or circulating neurohormones in dogs with heart failure (HF). Tolvaptan shows a decrease in kidney weight as well as in cyst and fibrosis volume in animal models of human polycystic kidney disease (PKD). [1] Tolvaptan markedly elevates electrolyte-free water clearance (E-CH(2)O) or aquaresis to a positive value and increases urinary Arginine vasopressin (AVP) excretion in rats with heart failure. [3]

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.
