Provided are a cross-bridged tetraaza macrocyclic compound of a novel structure that can be used, for example, as a contrast agent for diagnostic imaging or a radiopharmaceutical and a method for preparing the same.
The disclosed tetraaza macrocyclic compound is able to form a stable metal complex at a lower temperature and allows easy conjugation with a bioactive substance or a chemically active substance, when compared to the existing cross-bridged tetraaza macrocyclic compounds.
提供了一种新结构的交叉桥联四氮杂大环化合物,可用作例如诊断成像对比剂或放射性药物,并提供了制备该化合物的方法。所披露的四氮杂大环化合物能够在较低温度下形成稳定的金属络合物,并且与现有的交叉桥联四氮杂大环化合物相比,易于与生物活性物质或化学活性物质结合。
