  • Immunoblots of inner medullas from control and tolvaptan-treated rats. Each lane was loaded with a sample from a different rat. Tolvaptan (2.5 mg/day) or vehicle was infused for 4 days. Loading: aquaporin-2 (AQP2), 15 μg; AQP3, 20 μg; AQP4, 25 μg; and urea transporter UT-A1, 25 μg. Values are normalized band densities covering all bands (means ± SE). *Statistical significance (P < 0.05, t-test).

Biological Activity

Description Tolvaptan 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

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 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.

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
