摘要: 纤维素硫酸钠(Na-CS MC )具有突出的抗凝血活性‚为了研究硫酸酯基取代度(D S )与其抗凝血活性的构效关系‚需要构建具有不同 D S 值的纤维素硫酸钠类似物化学库.文中采用酸水解和柱层析分离的方法‚获得了同一相对分子质量下具有不同 D S 值的
Na-CS MC 样品‚研究了 Na-CS MC 的硫酸酯取代度对其抗凝血效果和对凝血因子抑制作用的影响规律.结果表明‚在一定范围内‚随着 D S 值增大‚Na-CS MC 对活化部分凝血活酶时间(t APPT )和凝血酶时间(t TT )的延长作用增强‚对凝血因子Ⅱa 和 Xa 的抑制作用提高.

Abstract:  Cellulose sulfate sodium (Na-CS MC ) is of excellent anticoagulation activity.In order to study the structure-activity relationship between the anticoagulation activity and the substitution degree ( D S ) of Na-CS MC ‚a chemical stock of Na-CS MC analogues with different D S values must be established.In this paper‚Na-CS MC samples with differ-ent D S values and the same relative molecular mass were obtained by means of acid hydrolysis and chromatography separation.The effect of the substitution degree of Na-CS MC on the anticoagulation activity and the inhibition of coagu-lation factors was also investigated.The results indicate that both the prolongation of activated partial thrombo-plastin time and thrombin time and the inhibition to the two anticoagulation factors (Ⅱaand Xa) caused by Na-CS MC improve with the increasing of D S value within a certain range.
