Efficacy of ARBs at preventing StAR upregulation in SII-stimulated H295R cells. (A,B) Western blotting for StAR protein levels in H295R cells transfected to overexpress barr1 and treated for 6 hrs with 10 μM SII alone (SII) or in the presence of 10 μM of each of the sartans tested. Representative blots of 3 independent experiments are shown in (A), including blots for barr1 to confirm its overexpression and for GAPDH (glyceraldehyde 3-phosphate dehydrogenase) as loading control, and the StAR protein induction (as % of the SII response), as derived by densitometric quantification, is shown in (B). *, p <0.05, n=3 independent experiments/treatment. Blots shown have been cropped to fit space requirements and run under the same experimental conditions (same gel) (the full length blots are shown in Supplementary Information). (C,D) Western blotting for StAR protein levels in dominant negative barr1 mutanttransfected H295R cells and treated as in (A-B). Representative blots are shown in (C), including blots for the dominant negative barr1 mutant to confirm its overexpression and for GAPDH as loading control, and the StAR protein induction (as % of vehicle-no stimulation), as derived by densitometric quantification, is shown in (D). No significant differences were observed among treatments, nor did any treatment cause any induction in StAR levels. Blots shown have been cropped to fit space requirements and run under the same experimental conditions (same gel) (the full length blots are shown in Supplementary Information). n=3 independent experiments/treatment. LOS: Losartan-; VAL: Valsartan; CAN: Candesartan; OLM: Olmesartan; IRB: Irbesartan.

Immunofluorescence analysis of HBcAg expression at day 10 after irbesartan administration for HBV (genotype D) infection at MGE 200. The m47F peptide (400 nM) and ezetimibe (50 lM) were used as positive controls for HBV entry inhibition.

|Description||Irbesartan (SR-47436, BMS-186295) is a highly potent and specific angiotensin II type 1 (AT1) receptor antagonist with IC50 of 1.3 nM.|
|Features||Irbesartan is a longer acting AT1 receptor antagonist relative to losartan and valsartan.|
Irbesartan competes with angiotensin II (AII) for binding at the AT1 receptor subtype and antagonizes AII-induced contraction in rabbit aorta ring with IC50 of 4 nM. Irbesartan has no affinity for AT2 receptors.  Irbesartan (10 μM) blocks angiotensin II induced increase in αv, β1, β3, and β5 integrins, osteopontin, and α-actinin mRNA and protein levels in rat cardiac fibroblasts, leading to the decrease of cell attachment to extracellular matrix (ECM) proteins.  Irbesartan treatment markedly induces the expression of the adipogenic marker gene adipose protein 2 (aP2) in 3T3-L1 cells in a concentration-dependent manner with EC50 of 3.5 μM and 3.3-fold induction at the concentration of 10 μM. Irbesartan (10 μM) markedly induces transcriptional activity of the peroxisome proliferator–activated receptor-γ (PPARγ) by 3.4-fold independent of its AT1 receptor blocking action.  Pretreatment with Irbesartan (~10 μM) decreases angiotensin II-induced apoptosis in rat vascular smooth muscle cells by blocking angiotensin II internalization in a concentrationdependent manner. 
|In vivo||Oral administration of Irbesartan (1 mg/kg) reduces angiotensin II (AII)-induced hypertension, equipotent with losartan in conscious normotensive rats, markedly more active than losartan (10 mg/kg) in normotensive cynomolgus monkeys.  Administration of Irbesartan (7 mg/kg/day) significantly prevents skeletal muscle apoptosis and muscle atrophy in rats with monocrotaline-induced congestive heart failure (CHF), which is involved with the decrease of TNFα level and attributed to AT1 receptor blocking. |

|In vitro||DMSO||4 mg/mL warmed (9.33 mM)|
|Ethanol||3 mg/mL (7.0 mM)|
|In vivo||Add solvents to the product individually and in order(Data is from Selleck tests instead of citations):
30% PEG400+0.5% Tween80+5% propylene glycol
For best results, use promptly after mixing.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

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.
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).
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.
