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 10-5sec-1 to 2.5 x 10-5sec-1 in isotonic aqueous media at pH 7.4 at 37
一种链激酶-人纤溶酶原激活剂复合物的衍生物可用于治疗静脉血栓,在这种衍生物中,对纤维蛋白溶解活性至关重要的活性催化位点被 2-或 4-氨基苯甲酰基阻断。
阻断基团可通过水解作用移除,因此在 37
