    • The present invention provides metal chelating compounds, to chelates and chelate-targeting agent conjugates formed from the chelating compounds, and to methods for making and using these compositions. The chelating compounds incorporate two nitrogen atoms and three sulfur atoms ("N.sub.2 S.sub.3 "), two nitrogen atoms and four sulfur atoms ("N.sub.2 S.sub.4 "), or three nitrogen atoms and three sulfur atoms ("N.sub.3 S.sub.3 "). Metals, and metal oxides, capable of being chelated by the compounds include those that are radionuclides, such as .sup.99m Tc and .sup.186/188 Re.The targeting agent portion of the chelate-targeting agent conjugates provided includes antibodies, peptides, hormones, enzymes and biological response modifiers. Methods for making the conjugates are provided and encompass the addition of a metal, or metal oxide, to a chelating compound prior to attachment to a targeting agent as well as subsequent to the attachment.Another aspect of the invention provides kits for producing chelate-targeting agent conjugates for radiopharmaceutical use.An additional aspect of the invention provides methods for using the chelate-targeting agent conjugates for diagnostic and therapeutic purposes, such as detection of a target site and delivery of a radionuclide to the site, respectively.
    • 本发明提供金属螯合化合物,由螯合化合物形成的螯合物和螯合靶向试剂缀合物,以及制备和使用这些组合物的方法。 螯合化合物包含两个氮原子和三个硫原子(“N2S3”),两个氮原子和四个硫原子(“N2S4”)或三个氮原子和三个硫原子(“N3S3”)。 能够被化合物螯合的金属和金属氧化物包括那些是放射性核素,例如99mTc和186 / 188Re。 提供的螯合靶向药物缀合物的靶向剂部分包括抗体,肽,激素,酶和生物反应调节剂。 提供了制备缀合物的方法,并且包括在附着到靶向剂之前以及在附着之后将金属或金属氧化物加入到螯合化合物中。 本发明的另一方面提供了用于制备用于放射性药物用途的螯合靶向剂缀合物的试剂盒。 本发明的另一方面提供了用于诊断和治疗目的的螯合靶向剂缀合物的使用方法,例如分别检测靶位点和将放射性核素递送至位点。
