• inhibitor
  • The drug aprotinin (Trasylol, previously Bayer and now Nordic Group pharmaceuticals), is a small protein bovine pancreatic trypsin inhibitor (BPTI), or basic trypsin inhibitor of bovine pancreas, which is an antifibrinolytic molecule that inhibits trypsin and related proteolytic enzymes. (wikipedia.org)
  • Because of the usual source organism, BPTI is sometimes referred to as bovine pancreatic trypsin inhibitor. (wikipedia.org)
  • Aprotinin is a competitive inhibitor of several serine proteases, specifically trypsin, chymotrypsin and plasmin at a concentration of about 125,000 IU/ml, and kallikrein at 300,000 IU/ml. (wikipedia.org)
  • small
  • Its physiological functions include the protective inhibition of the major digestive enzyme trypsin when small amounts are produced, by cleavage of the trypsinogen precursor during storage in the pancreas. (wikipedia.org)
