A new structure-based strategy for the design of potent and selective plasmin inhibitors was developed. These compounds could be prepared by cyclizations between the P3 and P2 amino acid residues of substrate-analogue inhibitors using metathesis or a copper-catalyzed azide alkyne cycloaddition in combination with standard peptide couplings. The most potent bis-triazole derivative 10 inhibits plasmin and plasma kallikrein with Ki of 0.77 and 2.4 nM, respectively, whereas it has poor activity against the related trypsin-like serine proteases thrombin, factor Xa, or activated protein C. Modeling experiments revealed that inhibitor 10 adopts a compact and rigid structure that fits well into the relatively open active site of plasmin and plasma kallikrein, while it is rejected from sterically demanding residues present in loops of the other enzymes. These results from modeling confirm the selectivity profile found for inhibitor 10 in enzyme kinetic studies. Such compounds might be useful lead structures for the development of new antifibrinolytic drugs for use in cardiac surgery with cardiopulmonary bypass or organ transplantations to reduce bleeding complications.

Page/Page column 51, (2010/02/09)
The invention relates to N-sulphonylated amino acid derivatives wherein an aryl radical is bound to an amino acid via the sulphonyl groups in the N-terminal and a radical is bound in the C-terminal via the carbonyl group. Said radical contains at least one imino group and at least one other basic group representing an optionally modified amino-, amidino- or guanidino group. The invention also relates to a method for the production of said compounds and to the use thereof, especially as inhibitors of matriptase.
