Abstract

본 발명은 스트렙토키나제와 다당류를 결합시켜 얻은 공유결합체 및 그 제조 방법에 관한 것이다.The present invention relates to a covalent conjugate obtained by combining streptokinase and a polysaccharide and a method for producing the same.

본 발명의 스트렙토키나제와 다당류의 공유결합체는 다당류의 히드록시 메틸기를 산화시켜 알데히드가 반응기로서 부가된 다당류를 얻은 다음 스트렙토키나제와 쉬프염을 형성시킨 후 이를 환원시켜 제조한다.The covalent conjugate of the streptokinase and the polysaccharide of the present invention is prepared by oxidizing the hydroxy methyl group of the polysaccharide to obtain a polysaccharide to which aldehyde is added as a reactor, and then forming a Schiff salt with streptokinase and reducing it.

본 발명의 목적물은 체내 안정성 가와 항원성 감소는 물론 임상에 직접 사용할 수 있는 안전성도 높다.The object of the present invention has high stability in the body and antigenicity, as well as high safety that can be used directly in the clinic.
