生物活性

Phosphoramidon Disodium is a metalloprotease inhibitor. Phosphoramidon 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.

体外研究

Phosphoramidon is a naturally occurring glycopeptide first isolated from a strain of Streptomyces tanashiensis. It has a unique chemical structure featuring a phosphoramidate linkage between a-L-rhamnose and L-leucineL-tryptophan. As a microbial metabolite, phosphoramidon exhibits potent inhibitory activity against thermolysin, a zinc endopeptidase isolated from Bacillus thermoproteolyticus (Ki=32 nM).

体内研究

Intranasal administration of phosphoramidon produces significantly elevated cerebral Aβ levels in wild-type mice. Furthermore, intranasal phosphoramidon administration in double knockout mice lacking NEP and NEP2 also shows increased levels of Aβ40. Phosphoramidon blocks the formation of endothelin-1 (ET-1), a proinflammatory mediator implicated in the pathogenesis of a variety of lung diseases. Phosphoramidon significantly reduces LPS-induced pulmonary inflammation as measured by lung histology, neutrophil content of bronchoalveolar lavage (BAL) fluid, percent tumor necrosis factor receptor 1 (TNFR1)-labeled BAL macrophages, and alveolar septal cell apoptosis. Phosphoramidon significantly decreased ET-1 levels, causing a concomitant big ET-1 increase and dose-dependently attenuated indomethacin-induced gastric mucosal damage.
