Pirodomast is a thromboxane A (TXA2) synthase inhibitor. Pirodomast inhibits leukotriene (LT) D4, C4, E4 formation and thromboxane B2 (TXB2) activity, but is weakly or ineffectively antagonistic to guinea pig bronchospasm induced by histamine, methacholine, serotonin, LTC4, or platelet-activating factor. Pirodomast is a potential antiallergic compound. Pirodomast had only weak relaxant activity on guinea pig trachea in vitro. Pirodomast is a potential antiallergic compound that inhibits the protein hydrolyzing activity of trypsin in vitro, prevents antigen-induced immediate and late asthmatic responses in allergic sheep in vivo, and inhibits antigen-induced airway hyperresponsiveness to histamine and carbachol in allergic sheep.

Patamostat (E-3123) is a potent protease inhibitor that effectively inhibits trypsin, plasmin, and thrombin with IC50 values of 39 nM, 950 nM, and 1.9 µM, respectively. Research suggests it might suppress the pathogenesis and development of acute pancreatitis [1] [2].

VR23 is a potent proteasome inhibitor. Data shows IC50 =1 nM for trypsin-like proteasomes, IC50=50-100 nM for chymotrypsin-like proteasomes, and IC50=3 μM for caspase-like proteasomes.

Diminazene is a trypanocidal agent.

Marizomib is a novel irreversible brain-permeable proteasome inhibitor that inhibits CT-L (β5), CT-T-laspase-like (C-L, β1), and trypsin-like (T-L, β2) 20S proteasomes with IC50s of 3.5, 28, and 430 nM.[3]

N-alpha-Tosyl-L-lysine chloromethyl ketone hydrochloride (N-alpha-Tosyl-L-lysine_chloromethyl_ketone_hydrochloride) is an inhibitor of trypsin-like protease and exhibits an inhibitory effect on IFN-γ activities.

TCH-165 is a small molecule modulator of proteasome assembly, resulting in an increase in 20S levels. The increase in the level of free 20S corresponds to enhanced proteolysis of IDPs.

Benzamidine is a reversible competitive inhibitor of trypsin with a Ki of 19 μM. It also exhibits inhibitory activity on an enzyme in homogenized porcine sperm acrosome, with a Ki of 4 μM.
