Beschreibung
3,4-Dichloroisocoumarin (3,4-DCI) is a serine protease inhibitor. It completely inhibits enzyme activity of 24 serine proteases including human leukocyte elastase, thrombin, plasmin, Factor Xa, and Factor XIIa
in vitro. 3,4-DCI stimulates caseinolytic activity of bovine pituitary multicatalytic proteinase complex (MPC) by inducing a conformational change in the MPC that exposes the caseinolytic active site. It has been used to functionally characterize the catalytic activities of multiple proteases including rat liver MPC and extracellular lipase.
Verwenden
Useful in a rapid staining method for identification of macrophages; counts by this method were confirmed by the more complex morphological criteria, by phagocytosis, and by the presence of Fc receptors. It is an inhibitor of Chymotrypsin and Trypsin. ,4 Dichloroisocoumarin also inhibits granzymes A, B, and H, cathepsin G, neutrophil elastase, proteinase and blocks apoptotic internucleosomal DNA cleavage in thymocytes without the involvement of endonucleases.
Allgemeine Beschreibung
A potent irreversible inhibitor of serine proteases. Blocks apoptotic internucleosomal DNA cleavage in thymocytes without the involvement of endonucleases. Reacts with serine proteases to release an acylchloride moiety that can acylate another active site residue. Does not affect thiol proteases and metalloproteases. Also has no activity towards β-lactamases. Effective at concentrations ranging from 5-100 μM.
