Application

Nafamostat mesylate has been used:
  • as a serine protease inhibitor to study its effects on proteolytic degradation of therapeutic proteins recombinantly expressed in Chinese hamster ovary (CHO)-K1-derived cells
  • to stop complement activation to validate the assay for murine C3 fragments
  • as a serine protease inhibitor to study its effects on house dust mite extract evoked Ca2+ entry

Biochem/physiol Actions

Nafamostat mesylate is a broad spectrum serine protease inhibitor, kallikrein inhibitor, and inhibits blood coagulation. It is also a possible complement inhibitor.
Nafamostat mesylate is used in the treatment of disseminated intravascular coagulation (DIC), pancreatitis, and systemic inflammatory response syndrome. It can block the proliferation, adhesion, and invasion of cancer cells and repress tumor progression in animal models. Nafamostat mesylate is involved in the development of immune activity. In combination with favipiravir, nafamostat mesylate may block virus entry and replication, and inhibit the pathogenic host response. This combination treatment might be effective for critically ill Covid-19 patients.

The activation of complement during platelet activation is incompletely understood. We sought to explore the formation of C5b-9 and anaphylatoxins binding to collagen-activated platelets. C5b-9, anaphylatoxins C3a, C4a and C5a, and anaphylatoxin receptors C3aR1 and C5aR were measured by flow
