Eight novel derivatives of MAG3, containing in their structure two instead of three amide functions, have been synthesized and evaluated. The synthesized ligands were labelled with 99mTc by exchange labelling at 100°C and/or by a direct labelling method at room temperature. After labelling with 99mTc, the reaction mixtures were analyzed by radio-HPLC. Biological evaluation of different 99mTc-diamide complexes in mice and a baboon indicated that substitution in one amide function of MAG3 structure greatly influences the renal handling of these compounds. It was found that the diamide derivatives containing at least one inverted amide exhibit biological behavior comparable to that of 99mTc-MAG3. Copyright © 2002 John Wiley & Sons, Ltd.
我们合成并评估了八种新型 MAG3 衍生物,它们的结构中含有两个而非三个酰胺功能。合成的配体在 100°C 下通过交换标记法和/或室温下通过直接标记法进行 99mTc 标记。用 99mTc 标记后,用放射性-高效液相色谱法对反应混合物进行分析。在小鼠和狒狒体内对不同的 99mTc 二酰胺复合物进行的生物学评估表明,MAG3 结构中一个酰胺功能的取代极大地影响了这些化合物的肾脏处理能力。研究发现,至少含有一个倒置酰胺的二酰胺衍生物具有与 99mTc-MAG3 相似的生物学行为。Copyright © 2002 John Wiley & Sons, Ltd.
