General description

A potent, selective, reversible, and competitive non-peptide inhibitor of cathepsin G (IC50 = 53 nM and Ki = 63 nM). Weakly inhibits chymotrypsin (Ki = 1.5 µM) and does not have any significant inhibitory effect on thrombin, factor Xa, factor IXa, plasmin, trypsin, tryptase, proteinase 3, and human leukocyte elastase (IC50 >100 µM).
