The present invention provides a novel class of macrocyclic compounds 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 incorporate hydroxy-isophthalamide 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. These characteristics distinguish them from known, open-structured ligands.
本发明提供了一种新的大环化合物类别,以及由金属(例如镧系金属)离子和本发明中化合物形成的配合物。首选的配合物在水介质中表现出高稳定性以及高量子产率的镧系离子发光特性,无需使用次级活化剂。首选化合物在其大环结构中包含羟基异苯酰胺基团,并以惊人的低非特异性结合多种多肽(如抗体和蛋白质)以及高动力学稳定性为特征。这些特征使它们与已知的开放结构配体有所区别。
