Lanthanide chelates which contain three heterocyclic rings covalently coupled to each other (either one 2,6-pyridylene and two five-membered unsaturated heterocyclic ring moieties or two 2,6-pyridylene and one five-membered unsaturated heterocyclic ring moiety) and two chelating groups so seated that they together chelate the same lanthanide ion even in aqueous solutions. These lanthanide chelates can optionally contain a reactive group for coupling to biologically active molecules. The new chelates are suitable for classical lanthanide chelate applications and are also useful as probes in time-resolved fluorescence microscopy, cytometry, multilabelling techniques and in process controls in industry.
含有三个杂环的镧系元素螯合物,这三个杂环通过共价键彼此连接(要么是一个2,6-吡啶基和两个五元不饱和杂环基团,或者是两个2,6-吡啶基和一个五元不饱和杂环基团)以及两个螯合基团,它们共同螯合同一个镧系离子,即使在水中。这些镧系螯合物可以选择性地含有一个反应性基团,用于与生物活性分子耦合。新的螯合物适用于经典的镧系螯合物应用,并且也作为探针在时间分辨荧光显微镜、细胞测量学、多重标记技术和工业过程中的控制中非常有用。
