报道了N-{2(1H吡咯基甲基)}N’-(4-戊烯-3-酮-2)-1,2-乙二胺(MRP20)的光谱数据与结构相符;元素分析结果与理论值一致;MRP20在室温下用亚锡还原可与~(99m)TcO(Ⅲ)生成配合物,标记率和放化纯大于90％。
The spectral data of N- {2 (1H-pyrrolylmethyl)} N’- (4-penten-3-one-2) -1,2-ethanediamine (MRP20) Which is consistent with the theoretical value. MRP20 can be reduced with stannous tin (~ 99m) TcO (Ⅲ) at room temperature to form a complex with labeling rate and radiochemical purity more than 90%.
