文章报道了N,N'-乙撑-双(L-半胱氨酸乙酯)(ECD)及其衍生物MCD、n-PCD、n-BCD、t-BCD的合成、放化研究结果。ECD及其衍生物的物理常数和光谱数据与结构一致。ECD及其衍生物与
99m
Tc-GH进行配体交换,能与
99m
Tc(V)生成稳定的络合物,标记率为85-95%,它们的分配系数及HPLC的保留时间证实锝络合物酯溶性大小与酯基的碳原子个数呈正相关。

were reported here. ECD and its derivatives were synthesized and identified by IR. NMR. MS and elemental analysis. These compounds could exchange with
99m
Tc-GH (V) to form stable complexes. The labelling yields were 85-95%. The liposolubility of those
99m
Tc complexes are in positive correlation with the size of the alkal ester groups
which was confirmed by the partition coefficients and the retention times of HPLC.
