Phosphoramidon (119942-99-3) inhibits neutral endopeptidase 24.11 (NEP; Neprilysin; EC 3.4.24.11), Ki=2 nM.1?Also inhibits neprilysin 2 (Ki~2 nM).2?Also inhibits endothelin-converting enzyme (IC50?= 0.68 μM).3?Induces a dramatic increase in amyloid-beta levels in rodents.4
An endothelin-converting enzyme inhibitor, attenuates lipopolysaccharide-induced acute lung injury.
Phosphoramidon is an inhibitor of NEP 24.11 and NEP2. It is an inhibitor of the enzyme thermolysin, a membrane metallo-endopeptidase inhibitor, and an endothelin converting enzyme inhibitor.
Phosphoramidon [N-(α-rhamnopyranosyl-oxyhydroxyphosphinyl)-Leu-Trp] is a competitive inhibitor of several soluble zinc metalloproteases. Phosphoramidate is produced naturally by Streptomyces?tanashiensis.
Phosphoramidon can inhibit ZMPSTE24, an integral membrane protein zinc metalloprotease. It is capable of blocking thermolysin.
