Product details
- Chemical name: (Z)-2-(1,3-benzodioxol-5-yl)-3-[[3-[4-[2-(4-hydroxy-3-iodophenyl)ethylamino]-4-oxobutoxy]-4,5-dimethoxyphenyl]methyl]-4-(4-methoxyphenyl)-4-oxobut-2-enoic acid.
- CAS number: 1027525-70-7
- Molecular formula: C39H38INO11.
- Purity: >98%
- Concentration: 1-100 nM.
- Form: Lyophilized powder.
- Solubility: Soluble in DMSO. Centrifuge all products before use (10000 x g 5 min).
- Reconstitution: Centrifuge the vial before adding solvent (10,000 x g for 5 minutes) to spin down all the powder to the bottom of the vial. The lyophilized product may be difficult to visualize. Add solvent directly to the centrifuged vial. Tap the vial to aid in dissolving the lyophilized product. Tilt and gently roll the liquid over the walls of the vial. Avoid vigorous vortexing. Light vortexing for up to 3 seconds is acceptable if needed. The product is soluble in pure water at high micromolar concentrations (100 µM - 1 mM). For long-term storage in solution, we recommend preparing a stock solution by dissolving the product in double-distilled water (ddH2O) at a concentration between 100-1000x of the final working concentration. Divide the stock solution into small aliquots and store at -20°C. Before use, thaw the relevant vial(s) and dilute to the desired working concentration in your working buffer. Centrifuge all product preparations before use. It is recommended to prepare fresh solutions in working buffers just before use. Avoid multiple freeze-thaw cycles to maintain biological activity
- Shipping: Shipped at room temperature. Product as supplied can be stored intact at room temperature for several weeks. For longer periods, it should be stored at -20°C.
- Target: ET-A receptors
- Source: Synthetic
- Activity: PD-164333 is a selective antagonist of the ET-A receptors, inhibiting Endothelin-1 radioligand binding to ET-A and ET-B receptors with Kd of 0.99 nM and 2.41 µM, respectively. in vitro, PD164333 shifts Endothelin-1 concentration-response curve to the right with pA2 of 8.84 in isolated human saphenous vein1.
Scientific background
PD-164333 is a synthetic compound that acts as a selective antagonist of ET-A endothelin receptor based on the butenolide series1. It inhibits the binding of radioligand endothelin-1 to left ventricle in a biphasic manner with a KD value of 0.99 nM and 2.41 µM towards ET-A and ET-B, respectively1.Endothelin receptors include two subtypes: ET-A and ET-B. They are widely distributed in vascular and nonvascular tissues. ET-A receptors are predominantly expressed in peripheral tissues, especially in vascular smooth muscle tissues to mediate vasoconstriction. They are also detected in different regions of the brain. ET-A receptor has a high affinity for endothelin-1 and endothelin-2 and relatively low affinity for endothelin-3, while the ET-B receptor has high affinity equally for all endothelin isopeptides2.
