    Abstract: Conjugates of formula (I), made from polyvinyl lactams and hirudin, desulphatohirudin or coagulation-inhibiting hirudin muteins are new. A = H, OH or CH3. n = 2-4; m = 50-500. B = -CO-, -CH=, -CH2-, -CH2-X-CO-, -CH2-X-Z-CO-, -CH2-X-CO-NH-Z-NH-CO-, -CH2-X-CH2-(1,4-Ph)-N2-, -CH2-X-CH2-CH(OH)-CH2-(1,4-Ph)-N2-, -CH2-X-CO-CH2-CH2-CO or -CH2-X-(4-W-(1,3,5-triazin-2,6-yl)). X = -S-, -O-, -NH-, -N(CH3)- or -N(C2H5)-. Z = 1-6C alkylene or p-phenylene. W = H, Cl or OH. Hir = the hirudin, desulphatohirudin or hirudin mutein, which is bound to B via the serine, threonine or lysine side chain(s). USE/ADVANTAGE - For the treatment and prevention of thromboembolic disorders (e.g. myocardial infarction), peripheral arterial occlusion disorders, deep venous thrombosis and pulmonary embolism. (I) can be used to prevent reocclusion after re-opening of arterial blood vessels by mechanical methods of lysis. Administration is i.v. or i.m. (I) have longer in vivo half life (1-100 hours) than hirudin alone (50 minutes) or even than hirudin-dextran conjugates (7 hours).

    Abstract: Hirudin-polyalkylene glycol conjugates (I) (A-(CH2)n-(O-(CH2)n)m-B-)pHir are new. In (I): A=OH, NH2, CH3CONH, COOH, COOR or OR; R = 1-4C alkyl; B = direct bond or a linker; Hir = hirudin, desulphatohirudin or hirudin mutein gp. linked via serine, threonine or lysine chain(s); m = 100-1000; n = 2-5; p = 1-4. Pref. the linker is (a) -O-(CH2)n-1-CH= or -O-(CH2)n-1-CO-; or (b) -X-CO-, -X-CO-NH-Z-NH-CO-, -X-CH2-p-Ph-N2-, -X-CH2-CH(OH)-CH2-p-Ph-N2-, -X-CO-CH2-CH2-CO-, -X-CH2-CO- or gp. of formula (i); R1 = H, Cl or OH; X = -S-, -O-, -N(H, CH3 or C2H5)-; and Z = 2-6C alkylene or p-phenylene. USE/ADVANTAGE - (I) are anticoagulants in human and veterinary medicine to treat and prevent e.g. myocardial infarct, peripheral arterial occlusions, deep vein thrombosis and pulmonary embolism. They are administered i.v. or i.m. (I) have a half-life of 1-100 hours, compared with 50 mins. for hirudin itself and 7 hours for hirudin-dextran. Further, (I) have high activity with only very slight antigenicity.
