摘要:
Compositions and methods for prevention and treatment of uncontrolled formation of intravascular fibrin clots, which are capable of selective dissolution of pathological nascent clots formed intravascularly, with minimal risk of unwanted dissolution of pre-existing hemostatic clots, are provided wherein fibrinolytic or anticoagulant drugs are biocompatibly coupled to red blood cell carriers.

摘要:
A method is provided for the use of a fragment of von Willebrand Factor (vWF) comprising the platelet glycoprotein Ib (GPIb) binding domain in conjunction with known therapies to obtain enhanced protection against thrombosis, improved thrombolysis, and a decreased likelihood of reocclusion following thrombolytic treatment. Additionally, a method is provided for the use of the vWF fragment and aspirin to prevent complications following traumatic vascular damage.
摘要:
Light activated acyl-enzymes of formula (III) are disclosed. In the compounds of formula (III) ENZ is an enzyme, X is O or S, Y is -NR3R4, -OR5, or -SR5, and Z is a nucleophile; m is 0 to 3 and n is 1 or 2; Y is substituted on the ring at either or both of the 4 and 6 position. R1 and R2 are each independently H, C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl. R3 and R4 are each independently H, C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl, except that R3 and R4 are not simultaneously both H. R5 is C1 to C4 alkyl, C3 to C4 unconjugated alkenyl, or C3 to C4 unconjugated alkynyl. Methods of using the acyl-enzymes and intermediates for making the acyl-enzymes are disclosed. A preferred intermediate is 2-propenoic acid, 3-(2-hydroxy-4-diethylaminophenyl)-2-methyl-, 4-(aminoiminomethyl)phenyl ester, (E)-, monohydrochloride salt, which is preferably reacted with thrombin to form an acyl-thrombin.
摘要:
Recombinant human plasminogen may be produced in invertebrate cells or in other eukaryotic cells lacking a site-specific plasminogen activator by expression of a vector including a gene encoding human plasminogen. Human plasminogen may thus be expressed without degradation by plasmin produced by intracellular plasminogen activators found in mammalian cells. The plasminogen product of such expression may be purified, acylated, complexed with acylated or non-acylated fibrinolytic enzymes and formulated into pharmaceutical compositions for use in thrombolytic therapy.
摘要:
A derivative of streptokinase-human plasminogen activator complex in which the active catalytic site essential for fibrinolytic activity is blocked by a 2- or 4-aminobenzoyl group, is useful in treating venous thrombosis. The blocking group is removable by hydrolysis such that the first order rate is in the range 0.7 x 10 -5 sec -1 to 2.5 x 10 -5 sec -1 in isotonic aqueous media at pH 7.4 at 37
摘要:
A method of making N-terminal methionine free polypeptide in a recombinant microbial host cell and pharmaceutical compositions along with one or more pharmaceutical excipients for management of various therapeutic disorders. Specifically, the invention relates to the production of N-terminal methionine free Streptokinase or human growth hormone by co expression with a protease enzyme in E.coli.
