Novel gadolinium complex compounds responsive to ions and compounds other than zinc ion, as well as MRI probes made of the compounds are disclosed. Since the gadolinium complex compounds of the present invention such as that represented by the following structural formula exhibit responsiveness to potassium ion, calcium ion, glucose or the like, by using the gadolinium complex compounds of the present invention as a MRI probe, the ion or compound in a living body can be detected and concentration distribution thereof may be determined.
本发明公开了对锌离子以外的离子和化合物有反应的新型钆络合物,以及由该化合物制成的磁共振成像探针。由于本发明的钆络合物(例如由以下结构式表示的化合物)对钾离子、钙离子、葡萄糖或类似物具有响应性,因此使用本发明的钆络合物作为磁共振成像探针,可以检测活体内的离子或化合物,并确定其浓度分布。
