This invention provides a process for preparing a fibrin-adsorable protein-urokinase complex characterized by reacting a protein adsorbable by fibrin with urokinase in the presence of a protein coupling reagent represented by the formula
wherein R is phenylene or cycloalkylene, A is lower alkylene, B is lower alkylene which may optionally be substituted by lower alkylthio or phenyl-lower alkylthio, and ℓ, m and n are each 0 or 1 provided that ℓ, m and n are not 0 at the same time.
The complex is useful as a thrombolytic agent.
本发明提供了一种制备纤维蛋白-可吸附蛋白质-尿激酶复合物的工艺,其特征在于在由式 所表示的蛋白质偶联试剂存在下,使可被纤维蛋白吸附的蛋白质与尿激酶反应。
其中 R 是亚苯基或环烷基,A 是低级亚烷基,B 是可被低级烷硫基或苯基-低级烷硫基取代的低级亚烷基,ℓ、m 和 n 各为 0 或 1,但 ℓ、m 和 n 不能同时为 0。
该复合物可用作血栓溶解剂。
