Serine proteases are enzymes that cleave peptide bonds in proteins, in which serine serves as the nucleophilic amino acidat the active site. They are found ubiquitously in both eukaryotes and prokaryotes. Serine proteases fall into two broad categories based on their structure: chymotrypsin-like or subtilisin-like. In humans, serine proteases are responsible for co-ordinating various physiological functions, including digestion, immune response, blood coagulation and reproduction. Threnonine proteases are a family of proteolytic enzymes harbouring a threonine (Thr) residue within the active site. The prototype members of this class of enzymes are the catalytic subunits of the proteasome, however the acyltransferases convergently evolved the same active site geometry andmechanism.

Nafamostat mesylate

Nafamostat mesylate, a synthetic serine protease inhibitor, is an anticoagulant.Target: Serine ProteaseTranilast (FUT-175) is an antiallergic drug for bronchial asthma. It has been used for the treatment of allergic disorders such as asthma, allergic rhinitis and atopic dermatitis. It has also been investigated for use as an antiproliferative drug on drug-eluting stents.A 20-40 mg/h dose of FUT-175 prolonged coagulation time sufficiently in the instrumental blood of the extracorporeal circuit but not in the systemic blood. Its anticoagulant activity decreased immediately after hemodialysis. Therefore, we could manage all patients without any bleeding trouble during hemodialysis with FUT-175 as an anticoagulant. Although there were side effects of FUT-175, such as nausea, vomiting, itching and eruption, they were not serious, and FUT-175 could be administered without interruption. FUT-175 seems to be useful as an anticoagulant during hemodialysis for patients susceptible to bleeding.
