Ulinastatin
CAS No. : 80449-31-6 (Trypsin Inhibitor Activity)

Short Description:

Source: Extracted from fresh male urine
Function and use: Ulinastatin is a protease inhibitor with a molecular mass of 67kD, which inhibits the activities of various hydrolases such as trypsin, chymotrypsin, lactate, lipase, and hyaluronidase. It can stabilize lysosomal membrane, inhibit the production of myocardial inhibitory factors, inhibit the release of lysosomal enzymes, scavenge oxygen free radicals, inhibit the excessive release of inflammatory mediators, improve human microcirculation and tissue perfusion, and play a protective role in tissues and organs. It is an effective drug for the treatment of acute pancreatitis, chronic recurrent pancreatitis, hemorrhagic, traumatic and endotoxic shock.
