    • The present invention relates to a blood coagulation factor Ⅶ derivative, a blood coagulation factor Ⅶa derivative, FacⅦ and FacⅦa conjugates each prepared by linking a polymer capable of extending the blood half-life to the derivative, FacⅦ and Ⅶa complexes each prepared by linking a carrier to the conjugate, genes encoding the FacⅦ and FacⅦa derivatives, expression vectors comprising the genes, transformants introduced with the expression vectors, a method for preparing the FacⅦ and FacⅦa derivatives using the transformants, a method for preparing the FacⅦa conjugate and complex, a FacⅦa complex prepared by the method, a pharmaceutical composition for the prevention or treatment of hemophilia comprising the derivative, conjugate, or complex as an active ingredient, and a pharmaceutical composition for blood coagulation comprising the derivative, conjugate, or complex as an active ingredient. Further, the present invention relates to a method for preventing or treating hemophilia or for promoting blood coagulation, comprising administering to a subject a therapeutically effective amount of the composition. The FacⅦ or FacⅦa derivative of the present invention is able to bind with a carrier capable of improving the blood half-life while maintaining the activity of FacⅦ or FacⅦa, and they can be widely used in the development of effective prophylactic or therapeutic agent for hemophilia.
    • 本发明涉及一种凝血因子Ⅶ衍生物,凝血因子Ⅶa衍生物,FacⅦ和FacⅦa缀合物,每种缀合物通过将能够延长血液半衰期的聚合物连接到衍生物上而制备,FacⅦ和Ⅶa复合物各自通过将 编码FacⅦa和FacⅦa衍生物的基因,包含该基因的表达载体,用该表达载体导入的转化子,使用转化体制备FacⅦ和FacⅦa衍生物的方法,制备FacⅦa缀合物和复合物的方法, 由该方法制备的FacⅦa复合物,包含该衍生物,缀合物或复合物作为活性成分的用于预防或治疗血友病的药物组合物,以及包含该衍生物,缀合物或复合物作为活性成分的用于凝血的药物组合物。 此外,本发明涉及用于预防或治疗血友病或促进凝血的方法,其包括向受试者施用治疗有效量的组合物。 本发明的FacⅦ或FacⅦa衍生物能够在保持FacⅦ或FacⅦa活性的同时与能够改善血液半衰期的载体结合,并且它们可以广泛用于开发有效的血友病预防或治疗剂 。
