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.

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].

In Vivo
Phosphoramidon (1-30 mg/kg; i.v.; once) blocks the pressor activity of porcine big endothelin-1-(1-39) in rats[5].

Cell Cytotoxicity Assay
Cytotoxicity assays are usually based on the assessment of cell membrane damage, which can also be indirectly detected by measuring cell viability. Detection methods include MTT assay, CKK-8 assay, LDH assay and ATP assay, etc.
