Abstract
It was found that in the interaction of xanthosine with copper(II) nitrogen N-7, and not oxygen atoms of carbonyl groups, is involved. In aqueous solution of XMP, copper(II) interacts not only with N-7 and the phosphate group but also with ribose. In a crystalline copper(II)-XMP complex [Cu(C10H11O9N4P).H2O], only the phosphate group and N-7 are involved.
摘要
研究发现，在黄苷与铜（II）的相互作用中，参与的是氮原子N-7，而非羰基的氧原子。在XMP的水溶液中，铜（II）不仅与N-7和磷酸基团相互作用，还与核糖相互作用。在晶体铜（II）-XMP配合物[Cu(C10H11O9N4P).H2O]中，仅磷酸基团和N-7参与其中。
