Ang II-induced MMP-2 protein expression through AT1 receptor in ex vivo cultured IAAA aortic walls (A) Ex vivo cultured aortic pieces from IAAA patients (n = 5) were incubated in the presence of different concentrations of Ang II for 48 h. (B) Ex vivo cultured aneurysmal aorta walls were pre-treated with either candesartan (10 µM, AT1R inhibitor) or PD123319 (10 µM, AT2R antagonist) for 48 h, followed by 1 µM Ang II treatment for 48 h. The group without Ang II incubation was used as control. **P < 0.01 vs. untreated control group; ##P < 0.01 vs. treated with Ang II alone. CA, candesartan; PD, PD123319.

Ang II induces MMP-2 protein expression and ERK phosphorylation ASMCs via AT1R. (a) ASMCs were pretreated with 0.1 μM candesartan (CA, selective AT1R inhibitor, 30 min) or 1 μM PD123319 (PD, selective AT2R inhibitor, 30 min) followed by stimulation with 0.1 μM Ang II for 2 min six-well plates. Western blot was performed to assess the levels of ERK phosphorylation in cell lysates. Top panel: Graphs show the relative p-ERK1/2 protein levels, respectively, normalized to total ERK1/2 relative to control. Bottom panel: Ratio of p-ERK1/2/t-ERK1/2 protein expression, respectively, evaluated using Western blot analysis from a representative experiment. Shown are mean±SEM of three individual experiments. **P < 0.01 vs. untreated control cells; ##P < 0.01 vs. cells treated with Ang II. (b) ASMCs were incubated with 1 μM candesartan or 10 μM PD123319 for 60 min before stimulation with 0.1 μM Ang II for 24 h in six-well plates. Western blot was used for analyses of the levels of MMP-2 expression in cell lysates. Top panel: Graphs show the relative MMP-2 protein levels normalized to GAPDH relative to control. Bottom panel: Ratio of MMP-2/GAPDH protein expression from a representative Western blot experiment. Shown are mean±SEM of three individual experiments. **P < 0.01 vs. untreated control cells; ##P < 0.01 vs. cells treated with Ang II.

|Description||PD 123319 is a potent, selective AT2 angiotensin II receptor antagonist with IC50 of 34 nM.|
PD 123319 is shown to discriminate between two subclasses of AII receptors in many different tissues. 125I-AII specifically labeled two classes of binding sites for AII in a membrane preparation of bovine adrenal glomerulosa cells. The first class (DuP-753 sensitive) represents approximately 85% of the total binding sites for AII and possesses a high affinity (IC50 of 92.9 nM) for DuP-753. PD-123319 does not have any effect on 125I-AII binding to this site. The second class of binding sites is more sensitive to PD-123319, with an IC50 of 6.9 nM, and has a much lower affinity for DuP-753 (IC50 around 10 microM). 
|In vivo||PD 123319 has no effect on cerebral blood flow autoregulation. Acute AT2-receptor blockade does not influence CBF autoregulation. Intravenous administration of PD 123319 to conscious hypertensive rats elicites an immediate dose-dependent increase in MAP that is sustained for approximately 7.4 min with 3 mg/kg PD 123319. |

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.

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 SDS / 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 SDS / 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.
