この製剤はselleckのラボで検証済みです。上記の溶解方法がご要望を満たさない場合、selleckの営業担当までお問い合わせ頂ければ、個別の試験を行います。

 30.000mg/ml (70.01mM) Taking the 1 mL working solution as an example, add 300 μL of 100 mg/ml clarified PEG400 stock solution to 5 μL of Tween80, mix evenly to clarify it; add 50 μL Propylene glycol to the above system, mix evenly to clarify it; then continue to add 645 μL ddH2O to adjust the volume. to 1 mL. The mixed solution should be used immediately for optimal results. 
* <1 mg/ml means slightly soluble or insoluble.
* 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.

生物活性

製品説明 Irbesartan is a highly potent and specific angiotensin II type 1 (AT1) receptor antagonist with IC50 of 1.3 nM.
in vitro

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. This compound has no affinity for AT2 receptors. [1] It (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. [2] This chemical 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. It (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. [3] Pretreatment with this compound (~10 μM) decreases angiotensin II-induced apoptosis in rat vascular smooth muscle cells by blocking angiotensin II internalization in a concentrationdependent manner. [4]
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. [1] Administration of this compound (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. [5]
特徴 Irbesartan is a longer acting AT1 receptor antagonist relative to losartan and valsartan.

キナーゼアッセイ Angiotensin II Binding Study on Rat Liver Membranes
The plasma membranes of livers are purified from male Sprague-Dawley rats, and diluted in the incubation buffer (20 mM Tris-HCI, 10 mM MgCI2, 2 g/L RSA, 145 mg/L bacitracin, pH 7.5). Aliquots of membrane suspension (20-330 μg protein/assay) are incubated for 1 hour at 25 °C with [125I]angiotensin II (AII) and various concentrations of this compound in 200 μL of incubation buffer. The incubation is stopped by rapid filtration through a Whatman GF/B filter followed by three consecutive washing sin 5 mL of cold incubation buffer (the GF/B filters are preincubated for 1 hour in the incubation buffer). The radioactivity bound to the filter is counted in a γ counter. Specific binding is defined as the difference between total binding and the binding in the presence of 1 μM unlabeled angiotensin II (AII). The concentration of this chemical producing 50% inhibition (IC50) of radioligand binding is determined from competition curve.
