Phosphoramidon Disodium, a microbial metabolite, is a specific metalloprotease thermolysin inhibitor with an IC50 of 0.4 μg/mL. Phosphoramidon Disodium also inhibits endothelin-converting enzyme (ECE), neutral endopeptidase (NEP), and angiotensin-converting enzyme (ACE) with IC50 values of 3.5, 0.034, and 78 μM, respectively

體外研究:
Phosphoramidon (1-500 μM; 30 min) inhibits ET-converting enzyme (ECE) activity in a dose-dependent manner in solubilized rabbit lung membranes
體內(nèi)研究:
Phosphoramidon (0.25 mg/kg per min; i.v.) suppresses the hypertensive effect of big endothelin-1 in rats. Phosphoramidon (1-30 mg/kg; i.v.; once) blocks the pressor activity of porcine big endothelin-1-(1-39) in rats. Animal Model: Male Sprague-Dawley rats Dosage: 0.25 mg/kg per min Administration: Intravenous injection Result: Markedly suppressed the hypertensive effect of big endothelin-1.
