    • A spectrofluorometric method for the detection of target structures by the use of two or more fluorescent lanthanide chelate probes for specifically marking each of said structures. The probes used differ with respect to their excitation or emission wavelength maxima. Also disclosed are certain lanthanide chelates that can be used in the method, either for synthesizing the probes or to be used directly as probes. The chelating ligand of these novel probes comprises two heterocyclic rings (preferably pyridyl) linked together so that jointly they can coordinate (chelate) one metal ion. The bridge linking the two rings together permits electron delocalization between the rings. Attached to their 6-positions the two rings carry chelating groups having heteroatoms (N, O or S) that participate in the chelation of the metal ion. Preferably the chelating groups at the 6-positions are -CH2N(CH2COOH)2, -CH2N(CH2CH2COOH)2, (a) or (b).
    • 用于通过使用两种或多种荧光镧系元素螯合探针来检测靶结构的分光荧光法,用于特别标记每个所述结构。 使用的探针在其激发或发射波长最大值方面不同。 还公开了可用于该方法的某些镧系元素螯合物,用于合成探针或直接用作探针。 这些新型探针的螯合配体包含两个连接在一起的杂环(优选吡啶基),因此它们可共同配合(螯合)一种金属离子。 将两个环连接在一起的桥允许环之间的电子离域化。 附着在它们的6位上,两个环带有具有参与金属离子螯合的杂原子(N,O或S)的螯合基团。 优选6位上的螯合基团是-CH 2 N(CH 2 COOH)2,-CH 2 N(CH 2 CH 2 COOH)2,(a)或(b)。

    • 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。
