Imaging (MRI) using paramagnetic systems as contrast agents is receiving increased attention as diagnostic tool in the clinic. At the same time, NMR of paramagnetic systems can also be applied in biochemical fields; for example, the use of Paramagnetic Relaxation Enhancement (PRE) allows structure refinement and the analysis of transient dynamic processes involved in macromolecular complex formation.

作为临床诊断工具,使用顺磁性系统作为造影剂的磁共振成像(MRI)受到越来越多的关注。同时,顺磁性系统的NMR也可以应用于生化领域。例如,顺磁弛豫增强(PRE)的使用可以使结构细化,并可以分析涉及大分子复合物形成的瞬态动力学过程。在这里,我们报告了一种新的类似DOTA的唾液酸共轭物的合成和计算表征,当与合适的顺磁性金属配合使用时,可以在MRI和PRE应用中使用。
