合成了树状聚胺胺代5 -叶酸缀合物,并用fac-[99mTc(CO)3(H2O)3]+进行了放射性标记,并对其进行了体外稳定性评价。G5-FA-DTPA-99mTc(CO)3缀合物的标记率和放射化学纯度均超过95%。在PBS和新生牛血清溶液中,分别有95.7%和93.1%的偶联物保持原有结构。
Dendrimer polyamidoamine generation five-folic acid conjugate was synthesesed and radiolabelled with fac-[99mTc(CO)3(H2O)3]+, its in vitro stability was evaluated further. Both of the labeling yield and radiochemical purity of the G5-FA-DTPA-99mTc(CO)3 conjugate exceeded 95%. More than 95.7% and 93.1% of the conjugate still keeps its original structure in PBS and new-born calf serum solution respectively.
