我们提出了一种简化的、自动化的单柱放射化学分离方法,使用萃取色谱支化 DGA 树脂来生产不添加载体的 Y-86,其放射化学产率高于 95%,表观摩尔活度为 1.4 +/- 0.4 Ci/mu mol (DOTA) 和 2.3 +/- 0.7 Ci/mu mol (DTPA),以及运行间循环效率。同位素富集目标为 98 +/- 1%。这些结果使得能够制备用于基于 Y-86/Y-90 的癌症治疗应用的 Y-86 放射性药物。
We present a simplified, automatable single-column radiochemical separation method using the extraction chromatographic branched-DGA resin for the production of no-carrier-added Y-86 with a radiochemical yield higher than 95%, an apparent molar activity of 1.4 +/- 0.4 Ci/mu mol (DOTA) and 2.3 +/- 0.7 Ci/mu mol (DTPA), and a run-to-run recycling efficiency of the isotopically-enriched target of 98 +/- 1%. These results enable the preparation of Y-86 radiopharmaceuticals for Y-86/Y-90-based cancer theranostic applications.
