With the interest in radiometal-containing diagnostic and therapeutic pharmaceuticals increasing rapidly, appropriate ligands to coordinate completely and stably said radiometals is essential. Reported here are two novel, bis(amido)bis(oxinate)diamine ligands, H2amidohox (2,2′-(ethane-1,2-diylbis(((8-hydroxyquinolin-2-yl)methyl)azanediyl))diacetamide) and H2amidoC3hox (2,2′-(propane-1,3-diylbis(((
随着对含放射性金属的诊断和治疗药物的兴趣迅速增加,完全和稳定地协调所述放射性金属的适当配体是必不可少的。这里报道了两种新型的双(酰胺基)双(辛二酸盐)二胺配体,H 2氨基氧杂环戊烷(2,2'-(乙烷-1,2-二基双(((8-羟基喹啉-2-基)甲基)氮杂二基)) diacetamide ) 和 H 2 amidoC3hox (2,2'-(propane-1,3-diylbis(((8-hydroxyquinolin-2-yl)methyl)azanediyl)) diacetamide),结合了两个 8-羟基喹啉和酰胺供体基团和它们的 1,2-乙二胺与 1,3-二氨基丙烷主链分别相差一个碳。两种配体都通过金属络合、溶液热力学和三种放射性金属离子的放射性标记进行了深入研究:[ nat/64 Cu]Cu2+、[ nat/111 In]In 3+和[ nat/203 Pb]Pb 2+。X 射线晶体学确定了六配位
