| In vitro |
Azilsartan medoxomil is a prodrug, which is rapidly converted to the active moiety, azilsartan (TAK-536), by ester hydrolysis in the gut and plasma during absorption after oral administration. Azilsartan selectively blocks the binding of angiotensin II to the AT1 (angiotensin II type 1) receptors found in the vascular smooth muscle and the adrenal gland, thereby promoting vasodilation and a decrease in the effects of aldosterone. [2] Azilsartan is a highly selective antagonist to the AT1 receptor, with an IC50 of 2.6 nM, exhibiting a >10,000-fold affinity for the AT1 receptor compared with the AT2 receptor, and has not shown affinity for other cardiac receptors or ion channels. The inhibitory effect of Azilsartan persists after washout of the free compound (IC50 value of 7.4 nM). Azilsartan also inhibits the accumulation of angiotensin II -induced inositol 1-phosphate (IP1) in the cell-based assay with an IC50 value of 9.2 nM, and this effect is resistant to washout (IC50 value of 81.3 nM).

Protocol
| Kinase Assay:[1] |
- Collapse
Radioligand Binding: A radioligand binding assay is performed by using human AT1 receptor-coated microplates containing 4.4 to 6.2 fmol of receptors/well (10 μg of membrane protein/well). Membrane-coated wells are incubated with 45 μl of assay buffer (50 mM Tris-HCl, 5 mM MgCl2, 1 mM EDTA, and 0.005% CHAPS, pH 7.4) containing various concentrations of test compounds at room temperature. After 90 min, 5 μl of 125I-Sar1-Ile8-AII (final concentration 0.6 nM) dissolved in assay buffer is added to the wells, and the plate is incubated for 5 h. In each step, the plate is briefly and gently shaken on a plate shaker. |

Bio Calculators
Molarity Calculator
Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:
Mass (mg) = Concentration (mM) × Volume (mL) × Molecular Weight (g/mol)
*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
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 )
* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

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.
