| 摘 要： | 以L(+)-酒石酸为原料,设计、合成了R,R构型的2种N4型配体以及99mTc的配合物,它们均为光化学纯结构,化合物通过了IR,1HNMR, 13CNMR及元素分析的测试. 进行了99mTc的标记,动物实验结果表明,2个目标物的99mTc标记配合物在小鼠肾中有较高的初始摄取量,尤其是N, N-二乙基酒石酸二乙二胺99mTc-配合物不仅有较高的肾摄取,且有较长的滞留时间,肾与血的活度比高,有望发展成为一种新的肾功能显像剂.

| Abstract: | Two new target chelators are synthesized through different active diamine with L (+) tartaric acid, 2,3 dihydrary succinic acid as primitive materials, all of which are identified on the basis of the spectroscopic data, such as IR, 1HNMR, 13 CNMR, and elementary analysis. All the chelators are labeled with technetium 99m and further tested for the biological activity in mice. The bio distribution results in mice indicate that 99m Tc B has high kidney uptake, good retention, quick blood clearance and high activity ratios of kidneys to other tissues, suggesting that it will be a new potential renal function imaging agent. |
