为了检验配合物分子中 [99mTcN]2 + 中心核的引入对其生物分布的影响以求找到一种新的放射性药物。采用SnCl2 ·2H2 O为还原剂 ,丁二酰二酰肼 (SDH)为N3 - 离子提供体 ,在室温下制备[99mTcN]2 + int 中间体 ,然后与配体N -异丁基 -... 为了检验配合物分子中 [99mTcN]2 + 中心核的引入对其生物分布的影响以求找到一种新的放射性药物。采用SnCl2 ·2H2 O为还原剂 ,丁二酰二酰肼 (SDH)为N3 - 离子提供体 ,在室温下制备[99mTcN]2 + int 中间体 ,然后与配体N -异丁基 -二硫代氨基甲酸钠 (IBDTC)发生配体交换反应得到99mTcN -IBDTC配合物。同时采用甲脒亚磺酸 (FSA)作还原剂对配体IBDTC进行了99mTc直接标记。结果表明 ,99mTcN -IBDTC和99mTc -IBDTC配合物的放化纯均大于 90 % ,小鼠体内生物分布表明 ,99mTcN -IBDTC有较高的脑摄取和较好的脑滞留 ,在注射后 5、30、6 0min时脑摄取量 (%ID·g- 1)分别为 6 .2 2、5 .4 5、3.88,脑 /血比值分别为 1.5 1、2 .2 4、1.84 ,有望成为一类新型脑灌注显像剂。99mTcN -IBDTC在心肌中也有较高的摄取 ,但心肌清除快而且心 /肝比值低从而限制了其成为一类新型心肌灌注显像剂。99mTc -IBDTC主要在肝内浓集 ,而脑、心肌摄取很少。本实验提示 ,放射性药物分子中引入 [99mTcN]2 + 核会引起生物分布性质的明显改变 ,这对于设计新型放射性药物具有参考价值。 展开更多

The potential use of radionuclides in therapy has been recognized for many decades. A number of radionuclides, such as iodine-131(^131I), phosphorous-32(^32P), strontium-90(^90Sr), and yttrium-90(^90Y), have been used successfully for the treatment of many benign and malignant disorders. Recently, the rapid growth of this branch of nuclear medicine has been stimulated by the introduction of a number of new radionuclides and radiopharmaceuticals for the treatment of metastatic bone pain and neuroendocrine and other malignant or non-malignant tumours. Today, the field of radionuclide therapy is enjoying an exciting phase and is poised for greater growth and development in the coming years. For example, in Asia, the high prevalence of thyroid and liver diseases has prompted many novel developments and clinical trials using targeted radionuclide therapy. This paper reviews the characteristics and clinical applications of the commonly available therapeutic radionuclides, as well as the problems and issues involved in translating novel radionuclides into clinical therapies. 展开更多
