| Outline of Final Research Achievements |
The aim of study is development of new radiopharmaceutical targeting amino acid transporter system ASC, and system N. Our research group discovered that system N transports the L-histidine(L-His) using our original screening system.
We tried iodine labeling for L-His because L-His was evaluated with promising results as base compound of new radiopharmaceutical targeting system N. As a result, high purity 125I-iodo-L-His(125I-IH) was defecated. According to experiment results, most of 125I-IH was transported into the cells by system L, however system N contributed 15% to transportation of 125I-IH in several tumor cell lines.
