| Hazard Information | Back Directory | [Description]
Cilastatin Na (81129-83-1) is a dehydropeptidase-1 inhibitor. Inhibits the proteolytic conversion of leukotriene D4?to E4.1? Inhibits the mammalian β-lactamase renal dipeptidase (dehydropeptidase-1, DPEP1) and thus is used as an antibacterial adjunct to extend the half-life of β-lactam antibiotics.2?Cilastatin also inhibits bacterial metallo-β-lactamase and thereby may block resistance to the carbapenem family of antibiotics in certain bacteria.3? Suppresses invasion and metastasis of DPEP1-expressing tumor cells.4 | [Chemical Properties]
White or light yellow amorphous, hygroscopic powder. | [Uses]
Enzyme inhibitor. | [Definition]
ChEBI: The monosodium salt of cilastatin. It is an inhibitor of dehydropeptidase I (membrane dipeptidase, 3.4.13.19), an enzyme found in the brush border of renal tubes and responsible for degrading the antibiotic imipenem. Cilastatin sodium is therefore administ
red with imipenem to prolong the antibacterial effect of the latter by preventing its renal metabolism to microbiologically inactive and potentially nephrotoxic products. | [General Description]
Cilastatin sodium salt is off-white to yellowish-white, hygroscopic, amorphous compound. It is derivatized from heptenoic acid. Its molecular mass is 380.43 g. | [Biological Activity]
Dipeptidase inhibitor (LTDase, leukotriene D4 hydrolase, dehydropeptidase I) that displays a K i value of 0.11 μ M. Inhibits metabolism of LTD 4 to LTE 4 and the hydrolysis of β -lactam antibiotics. Nephroprotective; reduces toxic accumulation of cyclosporin A in kidney proximal tubule epithelial cells. | [Biochem/physiol Actions]
Inhibitor of the renal enzyme dehydropeptidase I and some bacterial zinc-containing β-lactamases. By these action, cilastatin suppresses both host and target metabolism of the broad-spectrum antibiotic imipenem, improving its efficacy. | [References]
