The present invention provides for substituted metal chelating compounds in which at least two of the chelating atoms are nitrogen which are directly attached to aromatic rings and one or more of those nitrogen atoms has attached thereto a substituent other than hydrogen, and methods for making and using these compounds. Another aspect of the invention provides for the use of the chelation compounds described above in methods for diagnostic and therapeutic purposes. A diagnostic method is described for detecting the presence or absence of a target site within a mammalian host. This method comprises providing to cells a diagnostically effective dose of a compound of the present invention which contains a metal radionuclide, such as 99mTc and/or 111In, and detecting the biodistribution of the radionuclide. A therapeutic method is described for delivering a radionuclide, such as 186Re/188Re, 90Y, and 153Sm, to a target site within a mammalian host. This method comprises providing to cells a therapeutically effective dose of a chelate compound of the present invention.
本发明提供了取代的金属螯合化合物,其中至少有两个螯合原子是直接连接到芳香环上的氮原子,并且其中一个或多个氮原子上连接有除氢以外的取代基,本发明还提供了制造和使用这些化合物的方法。本发明的另一方面提供了上述螯合化合物在诊断和治疗方法中的用途。本发明描述了一种用于检测哺乳动物宿主体内目标位点存在与否的诊断方法。该方法包括向细胞提供诊断有效剂量的本发明化合物,其中含有金属放射性核素,如 99mTc 和/或 111In,并检测放射性核素的生物分布。描述了一种将放射性核素,如 186Re/188Re、90Y 和 153Sm 释放到哺乳动物宿主体内靶点的治疗方法。该方法包括向细胞提供治疗有效剂量的本发明螯合物。
