The rate of hydrolysis of 2'-chloro-2'-deoxycytidine and -uridine, and their 5'-phosphates, -diphosphates and polymers to the corresponding arabinocytidine and arabinouridine derivatives in the presence of Tris-HCL pH 8.9 is determined. This rate is highest for the nucleosides, less for the 5'-phosphates and 5'-diphosphates and even less for the polynucleotides. In the the 2'-chloro-2'-deoxyuridine series the O2, 2'-cyclonucleoside was formed in addition to the arabinonucleoside.
测定了2'-氯-2'-脱氧胞苷和-尿苷及其5'-磷酸酯、-二磷酸酯和聚合物在Tris-HCL pH 8.9存在下向相应阿糖胞苷和阿糖尿苷衍生物的水解速率。核苷的水解速率最高,5'-磷酸酯和5'-二磷酸酯的水解速率较低,多核苷酸的水解速率更低。在2'-氯-2'-脱氧尿苷系列中,除了阿拉伯核苷外,还形成了O2, 2'-环核苷。
