Several esters of 4-methylumbelliferone and 2-naphthol were synthesized and examined as possible spectrofluorimetric titrants for bovine alpha-chymotrypsin, trypsin, thrombin, Factor Xa and for subtilisin Novo. 4-Methylumbelliferyl p-guanidinobenzoate hydrochloride (MUGB) is a satisfactory titrant for alpha- and beta-trypsin, thrombin and Factor

Analytical biochemistry, 608, 113907-113907 (2020-08-20)
Snake venom prothrombin activators such as Ecarin are readily assayed by continuous spectrophotometric monitoring of p-nitroaniline production in a one step assay containing prothrombin and a p-nitroanilide peptide substrate for thrombin. The coupled reactions result in accelerating p-nitroaniline (pNA) production

LR769 is a new second-generation recombinant human Factor VIIa (rhFVIIa) developed for haemophilia treatment. We determined enzymatic properties of LR769 and its interaction with antithrombin, tissue factor, platelets and endothelial protein C receptor (EPCR), compared with NovoSevenRT. Kinetic enzyme assays

Laskowski inhibitors regulate serine proteases by an intriguing mode of action that involves deceiving the protease into synthesizing a peptide bond. Studies exploring naturally occurring Laskowski inhibitors have uncovered several structural features that convey the inhibitor's resistance to hydrolysis and
