Phosphoramidon Disodium Salt is a potent inhibitor of metalloproteinase [1].
Metalloproteinase is an enzyme whose catalytic mechanism involves a metal. Most metalloproteases require zinc and some require cobalt.
Phosphoramidon Disodium Salt is a potent metalloproteinase inhibitor. 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 [1]. 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 [2].
In anesthetized rats, phosphoramidon inhibited the hypertensive effect of big ET-1 [2]. In mice, phosphoramidon inhibited big ET-1 induced lethality and increased plasma IR-ET-1 through inhibition of the enzyme that converted big ET-1 to ET-1 [3].
