Plasmin is best known as the key molecule in the fibrinolytic system, which is critical for clot lysis and can initiate matrix metalloproteinase (MMP) activation cascade. Along with MMP, plasmin is suggested to be involved in physiological processes

Based on the structure of Tra-Tyr(O-Pic)-octylamide, a portion of the octylamine was replaced with moieties bearing hydrophobic, basic or acidic groups. Replacement of the C-terminal residue with a moiety bearing a hydrophobic group gave the proper a

Pseudo-peptide analogs of trans-4-aminomethylcyclohexanecarbonyl-L-phenylalanyl-4-aminopheny l acetic acid (PKSI-527, plasma kallikrein selective inhibitor), in which an amide bond (peptide bond) has been replaced by a CH2-NH bond, i.e., trans-4-amin

During the course of the development of active center-directed plasmin inhibitors, it was found that N-(trans-4-aminomethylcyclohexanecarbonyl)-lysine-4-methoxycarbonylanilide inhibited plasma kallikrein more potently than other enzymes such as plasm

We synthesized a new affinity gel (PKSI-Toyopearl) using a selective synthetic inhibitor of plasma kallikrein (PKSI-527) as an affinity ligand, and employed it for the rapid purification of plasma kallikrein from human plasma. Human plasma activated

The prothrombin assay method using the synthetic thrombin-inhibitor MD805 was standardized by fixing the concentrations of MD805 and S-2238 through their extinction coefficients (epsilon 333 for MD805 and epsilon 316 for S-2238). The prothrombin assa

Active center-directed inhibitors of plasmin were designed based on the structure of specific substrates of plasmin and then synthesized. Their effects on plasmin were examined and the structure-inhibitory activity relationship was studied. N alpha-t

MD805, a synthetic thrombin-inhibitor, effectively retarded the time-dependent inactivation of thrombin which was generated endogeneously or added exogeneously in human plasma. The kinetical study of the time-dependent inactivation indicated that the

A highly selective inhibitor of plasma-kallikrein (PK), N-(trans-4-aminomethylcyclohexylcarbonyl)-L-phenylalanine 4-carboxymethyl-anilide hydrochloride, was designed and synthesized by the authors' group, called PKSI-527 in our laboratories. (I) PKSI
