Nafamostat mesylate

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


Serine/cysteine protease inhibitor
PMSF is an irreversible serine/cysteine protease inhibitor.

SSR 69071

HLE inhibitor
SSR 69071 is a high affinity, potent inhibitor of Neutrophil Elastase (human leukocyte elastase, HLE) (IC50 = 3.9 nM).


Serine protease inhibitor
AAF-CMK is a serine protease inhibitor which irreversibly inhibits TPPII (tripeptidyl peptidase II), a giant protease which may substitute for some proteasome functions1, and reversibly inhibits Cln2 (TPPI).


Neutrophil elastase inhibitor
Sivelestat is a cell-permeable sulfanilide compound that acts as a potent, substrate-competitive, and highly specific inhibitor of neutrophil elastase (IC50 = 19-49 nM in rat, rabbit, hamster, human, and mouse leukocyte elastase).

A12779 SALE


neutrophil elastase inhibitor
Avelestat, also known as AZD9668, is a novel, oral inhibitor of neutrophil elastase (NE).

Sivelestat sodium salt

Neutrophil elastase inhibitor
Sivelestat sodium salt is a selective leukocyte elastase inhibitor (IC50 = 44 nM) that displays no activity at a range of other proteases. It inhibits NF-kB activation and LTB4-induced neutrophil transmigration in vitro.

Camostat mesylate

Camostat mesylate is an orally active protease inhibitor. Known to inhibit trypsin and various inflammatory proteases including plasmin, kallikrein and thrombin.

BCX 1470 methanesulfonate

Serine protease inhibitor
BCX 1470 is serine protease inhibitor. BCX 1470 blocks the esterolytic and hemolytic activities of the complement enzymes Cls and factor D in vitro.

BCX 1470

Serine protease inhibitor
