Phosphoramidon disodium salt is a potent metalloendopeptidase inhibitor, which is widely used as a biochemical research tool. Phosphoramidon In porcine aortic endothelial cells, phosphoramidon (10-4 M) inhibited immunoreactive-endothelin (IR-ET) release by 10-20% and increased IR-CTF levels. These results suggested that phosphoramidon reduced the IR-ET release through affecting the conversion of big ET-1 to ET-l. In cultured endothelial cells, phosphoramidon inhibited the increase of ET-1 and C-terminal fragment (CTF) of big ET-1. However, phosphoramidon increased big ET-1 secretion
| ln Vitro |
In solubilized rabbit lung membranes, phosphoramidon (1-500 μM; 30 min) suppresses ET-converting enzyme (ECE) activity in a dose-dependent manner[5].

| ln Vivo |
In rats, phosphoramidon (0.25 mg/kg per min; iv) inhibits large endothelin-1's hypertensive effect[4]. Rats' porcine large endothelin-1-(1-39) pressor activity is blocked by phosphoramidon (1-30 mg/kg; IV; once)[5].

| Animal Protocol |
Animal/Disease Models: Male SD (Sprague-Dawley) rats[4]
Doses: 0.25 mg/kg per min Route of Administration: intravenous (iv) injection Experimental Results: Markedly suppressed the hypertensive effect of big endothelin-1. |

| Solubility (In Vivo) |
Solubility in Formulation 1: ≥ 2.5 mg/mL (4.26 mM) (saturation unknown) in 10% DMSO + 40% PEG300 + 5% Tween80 + 45% Saline (add these co-solvents sequentially from left to right, and one by one), clear solution.
For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 400 μL PEG300 and mix evenly; then add 50 μL Tween-80 to the above solution and mix evenly; then add 450 μL normal saline to adjust the volume to 1 mL. Preparation of saline: Dissolve 0.9 g of sodium chloride in 100 mL ddH₂ O to obtain a clear solution. Solubility in Formulation 2: ≥ 2.5 mg/mL (4.26 mM) (saturation unknown) in 10% DMSO + 90% (20% SBE-β-CD in Saline) (add these co-solvents sequentially from left to right, and one by one), clear solution. For example, if 1 mL of working solution is to be prepared, you can add 100 μL of 25.0 mg/mL clear DMSO stock solution to 900 μL of 20% SBE-β-CD physiological saline solution and mix evenly. Preparation of 20% SBE-β-CD in Saline (4°C，1 week): Dissolve 2 g SBE-β-CD in 10 mL saline to obtain a clear solution. View More

*Note: Please select an appropriate solvent for the preparation of stock solution based on your experiment needs. For most products, DMSO can be used for preparing stock solutions (e.g. 5 mM, 10 mM, or 20 mM concentration); some products with high aqueous solubility may be dissolved in water directly. Solubility information is available at the above Solubility Data section. Once the stock solution is prepared, aliquot it to routine usage volumes and store at -20°C or -80°C. Avoid repeated freeze and thaw cycles.
