Any protease inhibitor that restricts the action of a serine protease.
| Member | Definition | Class |
|---|
| 3,4-dichloroisocoumarin | A member of the class of isocoumarins that is isocoumarin substituted by chloro groups at positions 3 and 4. It is a serine protease inhibitor. | 3,4-dichloroisocoumarin |
| benzamidine | A carboxamidine that is benzene carrying an amidino group. | benzamidine |
| camostat | A benzoate ester resulting from the formal condensation of the carboxy group of 4-guanidinobenzoic acid with the hydroxy group of 2-(dimethylamino)-2-oxoethyl (4-hydroxyphenyl)acetate. It is a potent inhibitor of the human transmembrane protease serine 2 (TMPRSS2) and its mesylate salt is currently under investigation for its effectiveness in COVID-19 patients. | camostat |
| camostat mesylate | A methanesulfonate (mesylate) salt prepared from equimolar amounts of camostat and methanesulfonic acid. It is a serine protease inhibitor approved and marketed in Japan in 1985 for the alleviation of acute symptoms associated with chronic pancreatitis. In 1994, it was approved for the treatment of postoperative reflux esophagitis. | camostat mesylate |
| leupeptin | A tripeptide composed of N-acetylleucyl, leucyl and argininal residues joined in sequenceby peptide linkages. It is an inhibitor of the calpains, a family of calcium-activated proteases which promote cell death. | leupeptin |
| melagatran | A member of the class of azetidines that is (2S)-azetidine 2-carboxylic acid in which the carboxylic acid has been converted to the amide corresponding to formal condensation with 4-(aminomethyl)benzenecarboximidamide and in which the hydrogen attached to the azetidine nitrogen is replaced by a (2R)-2-cyclohexyl-2-[(carboxymethyl)amino]acetyl group. | melagatran |
| pd 0348292 | A member of the class of pyrrolidines that is (2R,4R)-N(1)-(p-chlorophenyl)-4-methoxypyrrolidine-1,2-dicarboxamide in which the nitrogen of the 2-carbamoyl group has been substituted by a 2-fluoro-4-(2-oxopyridin-1(2H)-yl)phenyl group. It is a synthetic organic anticoagulant compound that targets activated factor Xa in the coagulation cascade. | eribaxaban |
| ximelagatran | A member of the class of azetidines that is melagatran in which the carboxylic acid group has been converted to the corresponding ethyl ester and in which the amidine group has been converted into the corresponding amidoxime. A prodrug for melagatran, ximelagatran was the first orally available direct thrombin inhibitor to be brought to market as an anticoagulant, but was withdrawn in 2006 following reports of it causing liver damage. | ximelagatran (hydroxylamine form); ximelagatran |
