Rat is a likely test animal for determining the efficacy of proteinase inhibitor drugs directed toward human leukocyte elastase and cathepsin G. We therefore sought to assess and compare relevant properties of both human and rat leukocyte elastase and cathepsin

Pentamidine is bis-oxybenzamidine-based antiprotozoal drug. The parenteral use of pentamidine appears to affect the processes of blood coagulation and/or fibrinolysis resulting in rare but potentially life-threatening blood clot formation. Pentamidine was also found to cause disseminated intravascular coagulation syndrome. To

A simple synthesis is described for 3-carboxypropionyl-Ala-Ala-Val-4-nitroanilide, a convenient and very specific substrate for human leukocyte elastase (Km = 1.0mM, kcat = 8.7 s-1). The substrate does not undergo appreciable spontaneous hydrolysis. It is not cleaved by trypsin or chymotrypsin

Cystic fibrosis (CF) lung disease is marked by high concentrations of neutrophil elastase (NE) and DNA polymers; both factors contribute to airway disease. Although inhaled recombinant human dornase alfa reduces the frequency of CF pulmonary exacerbations, it also increases free
