Web7.3.3.2 Bovine pancreatic trypsin inhibitor. BPTI is a small protein (58 residues) that was approved as an antifibrinolytic drug under the trade name Trasylol. However, the drug was withdrawn from the market in 2007 due to the risk of complications or death [114]; BPTI has since become available for limited use. Webbelongs to the bovine pancreatic trypsin inhibitor (BPTI)-like superfamily. It showed a dissociation con-stant of 5.8 108 M with -chymotrypsin as measured by a BIAcore binding assay system. The isothermal ti-tration calorimetry revealed a 1:1 binding stoichiometry between this inhibitor and chymotrypsin and appar-ently no binding with trypsin.
