The present invention provides a novel class of macrocyclic compounds of formula (I) as well as complexes formed between a metal (e.g., lanthanide) ion and the compounds of the invention. Preferred complexes exhibit high stability as well as high quantum yields of lanthanide ion luminescence in aqueous media without the need for secondary activating agents. Preferred compounds comprise hydroxypyridinonyl moieties within their macrocyclic structure and are characterized by surprisingly low, non-specific binding to a variety of polypeptides such as antibodies and proteins as well as high kinetic stability.
(I)
本发明提供了一类新型的式(I)大环化合物以及金属(如镧系元素)离子与本发明化合物之间形成的配合物。优选的配合物在水介质中表现出高稳定性和高镧系离子发光量子产率,无需二次活化剂。优选化合物在其大环结构中包含羟基吡啶壬基,其特点是与抗体和蛋白质等多种多肽的非特异性结合率低得出奇,并且具有很高的动力学稳定性。
