The present invention relates to the preparation of a series of chiral DOTA, DO3A, DO2A, DO1A, cyclen and their metal complexes, which display properties superior to those of previous DOTA-based compounds, and hence are potentially valuable as a platform for diagnostic applications. The chiral DOTAs reveal a high abundance of twisted square antiprism (TSA) geometry favoring them to be used as potential MRI contrast agents, whereas their rapid labelling properties at mild conditions make them excellent candidates for use as radiometal chelators.
本发明涉及一系列手性 DOTA、DO3A、DO2A、DO1A、cyclen 及其金属配合物的制备,这些配合物显示出优于以往 DOTA 类化合物的特性,因此具有作为诊断应用平台的潜在价值。手性 DOTAs 显示出高丰度的扭曲方形反棱柱(TSA)几何形状,有利于它们用作潜在的核磁共振成像造影剂,而它们在温和条件下的快速标记特性使它们成为放射性金属螯合剂的绝佳候选化合物。
