To develop a radioactive metal complex platform for tumor theranostics, we introduced three radiopharmaceutical derivatives of 1,4,7,10-tetraazacyclododecane-1,4,7-trisacetic acid-benzothiazole aniline (DO3A-BTA, L1) labeled with medical radioisotopes for diagnosis (68Ga/64Cu) and therapy (177Lu). The tumor-targeting ability of these complexes was demonstrated in a cellular uptake experiment, in which
为了开发用于肿瘤治疗的放射性金属复合物平台,我们引入了三种放射性药物衍生物,分别用标记有医用放射性同位素的1,4,7,10-四氮杂环十二烷-1,4,7-三乙酸-苯并噻唑苯胺(DO3A-BTA,L1)标记为诊断(68 Ga / 64 Cu)和治疗(177 Lu)。这些复合物的肿瘤靶向能力在细胞摄取实验中得到了证明,其中177 Lu-L1在HeLa细胞中的摄取明显高于177 Lu-1,4,7,10-四氮杂环十二烷-1,4,7, 10-四乙酸络合物。根据体内正电子发射断层扫描成像,高积累的68 Ga-L1和64Cu-L1在肿瘤部位清晰可见,而177 Lu-L1在治疗实验中显示出治疗功效。因此,当使用68 Ga-L1或64 Cu-L1进行诊断,177 Lu-L1进行治疗或将两种化合物结合使用时,此分子平台代表了一种在核医学中针对肿瘤-热疗放射性药物的有用方法。彼此。
