    摘要: The invention relates to materials and methods of conjugating a water soluble polymer to an oxidized carbohydrate moiety of a blood coagulation protein comprising contacting the oxidized carbohydrate moiety with an activated water soluble polymer under conditions that allow conjugation. More specifically, the present invention relates to the aforementioned materials and methods wherein the water soluble polymer contains an active aminooxy group and wherein an oxime linkage is formed between the oxidized carbohydrate moiety and the active aminooxy group on the water soluble polymer. In one embodiment of the invention the conjugation is carried out in the presence of the nucleophilic catalyst aniline. In addition the generated oxime linkage can be stabilized by reduction with NaCNBH
    3 to form an alkoxyamine linkage.

    摘要: The present invention relates to a proteinaceous construc (also designated as polymer-VWF-conjugate) comprising plasmatic and/or recombinant von Willebrand factor (VWF), said VWF being bound to at least one physiologically acceptable polymer molecule, as well as to a complex said proteinaceous construc and at least one factor VIII (FVIII) protein. The physiologically acceptable polymer molecule can be, for instance, polyethylene glycol (PEG) or polysialic acid (PSA). Further the present invention relates to methods for prolonging the in vivo-half-life of VWF or FVIII in the blood of a mammal having a bleeding disorder associated with functional defects of or deficiencies of at least one of FVIII or VWF.

    摘要: A method of factor Xl-dependent blood coagulation enhancement in a subject in need of enhanced blood coagulation comprising administering a therapeutically effective amount of a composition comprising a non-anticoagulant sulfated polysaccharide (NASP) to the subject. A method of factor Xl-dependent blood coagulation enhancement in a subject in need of enhanced blood coagulation comprising: (i) selecting a subject that is not deficient for factor Xl; and (ii) administering a therapeutically effective amount of a composition comprising a non-anticoagulant sulfated polysaccharide (NASP) to the subject, wherein the NASP enhances blood coagulation in a factor Xl-dependent manner. A method of identifying a non-anticoagulant sulfated polysaccharide (NASP) which is capable of enhancing blood coagulation in dependence on FXI, the method comprising: a) combining a blood or plasma sample comprising activation competent FXI with a composition comprising a sulfated polysaccharide and measuring the clotting or thrombin generation parameters of the blood or plasma sample; b) combining a corresponding blood or plasma sample deficient in activation competent FXI with a composition comprising the sulfated polysaccharide and measuring the clotting or thrombin generation parameters of the blood or plasma sample; and c) comparing the clotting or thrombin generation parameters of the blood or plasma samples as determined in steps (a) and (b) with each other, wherein a decrease in the clotting time of the blood sample or an increase in peak thrombin or decrease in peak time of the plasma sample comprising activation competent FXI compared to the clotting time of the blood sample or peak thrombin or peak time of the plasma sample deficient in activation competent FXI is indicative of a NASP which is capable of enhancing blood coagulation in dependence on FXI.
