Biological Activity

Description Nafamostat mesilate is a synthetic serine protease inhibitor, used as an anticoagulant during hemodialysis. Nafamostat mesylate blocks activation of SARS-CoV-2 and is investigated as a new treatment option for COVID-19. Nafamostat Mesilate attenuates inflammation and apoptosis.
Targets
serine protease [1]
In vitro

Nafamostat mesilate significantly inhibits the release of platelet beta-thromboglobulin (beta TG) at 60 and 120 min. Nafamostat mesilate (NM) prevents any significant release of neutrophil elastase; at 120 min, plasma elastase-alpha 1-antitrypsin complex is 0.16 mg/mL in the NM group and 1.24 mg/mL in the control group. Nafamostat mesilate completely inhibits formation of complexes of C1 inhibitor with kallikrein and FXIIa. [1]

Nafamostat mesilate inhibits several proteases which may be importantly involved in the pathophysiology of disseminated intravascular coagulation (DIC).Nafamostat mesilate inhibits extrinsic pathway activity (TF-F.VIIa mediated-F.Xa generation) in a concentration dependent manner with IC50 of 0.1 μM. [2]

Nafamostat mesilate produces concentration-dependent inhibition of the initial-phase transient component of biphasic ASIC3 currents with an IC50 value of approximately 2.5 mM. [3]
In vivo

Nafamostat mesilate (10 mg/kg) inhibits scratching induced by tryptase but not by histamine and serotonin. Nafamostat mesilate (1-10 mg/kg) produces the dose-dependent inhibition of scratching induced by intradermal compound 48/80 (10 mg/site). Nafamostat mesilate (10 mg/kg) suppresses tryptase activity in the mouse skin. [4]

Nafamostat mesilate inhibits gemcitabine-induced NF-kappaB activation, enhances apoptosis by gemcitabine and suppresses pancreatic tumor growth. Nafamostat mesilate combined with Gemcitabine improves the body weight loss of mice induced by Gemicitabine. [5]
