Patent number: 6284871Abstract: The present invention relates to biologically active peptides which specifically inhibit the Factor IX-dependent pathway of blood coagulation. These peptides are based on a specific motif which represents a sequence of Factor VIII (amino acid 1811-1818) involved in binding to activated Factor IX as well as to the intact Factor IX zymogen. Binding of said peptides to Factor IX or activated derivatives thereof effectively inhibits complex assembly with Factor VIII. These peptides thereby specifically interfere in the Factor IX-dependent pathway of thrombin formation, while leaving other haemostatic pathways unaffected. By virtue of this unique specificity, the peptides of this invention are particularly useful in novel pharmaceutical compositions for the treatment of thrombotic disorders.Type: GrantFiled: December 9, 1997Date of Patent: September 4, 2001Assignee: Stiching Centraal Laboratorium van de Bloedtransfusiedienst van Nederlandse Rode KruisInventors: Koenraad Mertens, Petrus Johannes Lenting

Patent number: 6083905Abstract: This invention relates to the diagnosis of congenital defects in the anticoagulant protein C system. Methods that are disclosed are based on the detection of mutations at the cleavage sites of coagulation factors that are under control of activated protein C (APC). Diagnostic tests include analysis of the APC-cleavage sites of factor V and factor VIII, by using specific primers to amplify selectively from RNA, cDNA derived from RNA or chromosomal DNA, parts of factor V and factor VIII that contain cleavage sites for APC. Methods that monitor the presence of mutations at the cleavage sites for APC and their utility in the diagnosis of thrombo-embolic disease are disclosed. The invention further discloses methods for correcting the defects detected according to the invention, as well as novel therapeutic agents which can be used in the treatment of bleeding disorders, which agents are based on the "defective" Factor V and Factor VIII proteins leading to the thrombotic disorders described hereinabove.Type: GrantFiled: January 22, 1997Date of Patent: July 4, 2000Assignee: Stichting Sanquin BloedvoorzieningInventors: Johannes Jacobus Voorberg, Jan Aart van Mourik, Koenraad Mertens

Patent number: 5932706Abstract: A method for the generation of Ca++ independent antibodies against blood coagulation factors is described wherein an antibody selection strategy based upon small peptides comprising target sequences for limited proteolysis is employed. These antibodies which distinguish between intact and cleaved species of haemostatic protein provide novel tools for the isolation of intact haemostatic proteins.Type: GrantFiled: February 10, 1997Date of Patent: August 3, 1999Assignee: Stichting Centraal Laboratorium Van De Bloedtransfusiedienst Van Het Nederlandse Rode KruisInventors: Koenraad Mertens, Jan Aart van Mourik
