Nafamostat Mesilate Is an Extremely Potent Inhibitor of Human Tryptase
Previously, nafamostat mesilate was found to be a potent inhibitor of human tryptase. In present study, we performed a kinetic study to determine its Ki value for tryptase and compared it with that of gabexate mesilate. Nafamostat mesilate inhibited human tryptase in a competitive manner. The appare...
