Nafamostat mesylate Usage And Synthesis

Description

Nafamostat mesylate is a protease inhibitor useful in the treatment of acute pancreatitis. It has anticomplement, anticoagulant, antikallikrein and other activities, and thus may have additional utility in the treatment of autoimmune diseases and disseminated intravascular coagulation.

Chemical Properties

Tan to pale orange solid

Originator

Torii (Japan)

Uses

A non-peptide proteaseinhibitor.

Uses

Nafamostat is an anticoagulant. Broad spectrum serine protease inhibitor. Reduces eosinophil infiltration, mast cell activation and airway responsiveness in a murine model of asthma

brand name

FUTHAN

Biological Activity

Broad spectrum serine protease inhibitor. Displays selectivity for human tryptase when used at relatively low concentrations. Reduces eosinophil infiltration, mast cell activation and airway responsiveness in a murine model of asthma.

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.

Synthesis

By p-guanidinobenzoic acid hydrochloride, 6-amidino groups-beta naphthal, 4,5-dicyano imidazole, methylene dichloride mix, 0-5 ℃ is stirred 1 hour, then improve temperature to 18-22 ℃, insulation reaction 8-12h, filters washed with dichloromethane, gained solid is 2 with methylsulfonic acid adjust pH, obtains nafamostat mesylate.

storage

Store at +4°C
