1. Phosphoramidon

Phosphoramidon, a microbial metabolite, is a specific metalloprotease thermolysin inhibitor with an IC50 of 0.4 μg/mL. Phosphoramidon 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.

At equivalent molar concentrations, both the salt and free forms of a compound exhibit comparable biological activity. Nevertheless, the salt form (Phosphoramidon Disodium) usually boasts enhanced water solubility and stability.

Description

Phosphoramidon, a microbial metabolite, is a specific metalloprotease thermolysin inhibitor with an IC50 of 0.4 μg/mL. Phosphoramidon 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[1][2][3].

IC50 & Target

IC50: 0.4 μg/mL (Thermolysin)[2], 0.034 μM (NEP), 3.5 μM (ECE), 78 μM (ACE)[3]

In Vitro

Phosphoramidon (1-500 μM; 30 min) inhibits ET-converting enzyme (ECE) activity in a dose-dependent manner in solubilized rabbit lung membranes[5].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

In Vivo

Phosphoramidon (0.25 mg/kg per min; i.v.) suppresses the hypertensive effect of big endothelin-1 in rats[4].
Phosphoramidon (1-30 mg/kg; i.v.; once) blocks the pressor activity of porcine big endothelin-1-(1-39) in rats[5].

Animal Model: Male Sprague-Dawley rats[4]
Dosage: 0.25 mg/kg per min
Administration: Intravenous injection
Result: Markedly suppressed the hypertensive effect of big endothelin-1.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
