摘要
加速器制备的α核素211 At是最适宜于靶向内放射治疗的理想核素之一。本文在参考最新文献的基础上,简要介绍了211 At标记放射治疗药物近年来取得的一些可喜进展,包括211 At的制备方法、标记物实验和临床研究以及标记方法等。对211 At标记放射治疗药物研究存在的问题、现状及临床应用前景也进行了探讨。
211At, produced by cyclontron, is a promising radioisotope for tumor targeted radiotherapy due to its favorable radiobiological characteristics and cytotoxicity. The progress of radiopharmaceuticals labeled with 211 At were reviewed with 50 references in recent years, including the preparation of 211At, the experimental and clinical research of labeled compounds, labeling methods, etc. Additionally, its situation, problems and prospect were discussed.
