    • The compounds of this invention are lanthanide chelates comprising 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. Optionally these lanthanide chelates also contain a reactive group for coupling to biologically active molecules. The new chelates of our invention find applications in those areas that are classical for lanthanide chelates. Moreover, these compounds are useful as probes in time-resolved fluorescence microscopy, cytometry, multilabelling techniques and process controls in industry.
    • 本发明的化合物是包含三个彼此共价偶联的杂环的镧系元素螯合物(一个2,6-亚吡啶基和两个五元不饱和杂环环部分或两个2,6-亚吡啶基和一个五元不饱和杂环部分 )和两个如此坐下的螯合基团,即使在水溶液中它们一起螯合相同的镧系元素离子。 任选地,这些镧系螯合物还含有用于与生物活性分子偶联的反应性基团。 本发明的新螯合物可用于那些经典镧系螯合物的领域。 此外,这些化合物可用作时间分辨荧光显微镜,细胞计数,多标签技术和工业过程控制中的探针。
