Sivelestat is a cell-permeable sulfanilide compound that acts as a potent, substrate-competitive, and highly specific inhibitor of neutrophil elastase (IC50 = 19-49 nM in rat, rabbit, hamster, human, and mouse leukocyte elastase). Sivelestat displays >100-fold greater selectivity over pancreas elastase (IC50 = 5.6 µM). Sivelestat does not inhibit trypsin, thrombin, plasmin, kallikrein, chymotrypsin, and cathepsin G even at concentrations as high as 100 µM. Sivelestat effectively suppresses human neutrophil elastase-induced lung hemorrhage and skin capillary permeability. Sivelestat is also reported to inhibit mast cell Stat6-protease.

I also want to know if this neutrophile elastase inhibitor could inhibit Pseudomonas elastase? I wonder if your campany have some information or products to specifically inhibit Pseudomonas elastase? Otherwise can you customize product?

Asked by: Jian L
Thank you for your question. In the context of this chemical, Sivelestat, there doesn’t seem to be any literature regarding inhibition of Pseudomonas elastase. Here is an article about Pseudomonas elastase that may be a helpful reference for your research, PMCID: PMC347797, In vitro inhibition of Pseudomonas aeruginosa elastase by metal-chelating peptide derivatives.
