| 摘 要： | 用~(99)Tc~m标记N-[2-(N-(2-巯基乙基))氨基甲酰甲基]-N-(2-巯基乙基)-3,5-二甲基金刚烷胺基乙酰胺(N_2S_2-Memantine),生成了~(99)Tc~m(V)-Memantine。采用纸层析对此标记物进行质控并检测其体外稳定性。结果显示,湿法的标记率>90%,药盒化标记的标记物经乙酸乙酯萃取纯化后,放化纯度>95%,体外稳定性良好,有望成为一种新的脑功能显像剂。

| Abstract: | N_2S_2-Memantine was labeled with ~(99)Tc~m using stannous fluoride as reducing agent,and the labeling conditions of ~(99)Tc~m-Memantine were optimized,and lyophilized kit of ~(99)Tc~m(V)-Memantine was also developed.The labeling efficiency was more than 90% by TLC and the kit radiochemical purity which was after extraction with ethyl acetate,was more than 95%.The stability was good in room temperature.~(99)Tc~m(V)-Memantine would be a potential brain imaging agent which would need more research work. |
