Design, Preparation, and Evaluation of a Novel (99m)TcN Complex of Ciprofloxacin Xanthate as a Potential Bacterial Infection Imaging Agent

In order to seek novel technetium-99m bacterial infection imaging agents, a ciprofloxacin xanthate (CPF2XT) was synthesized and radiolabeled with [(99m)TcN](2+) core to obtain the (99m)TcN-CPF2XT complex, which exhibited high radiochemical purity, hydrophilicity, and good stability in vitro. The bac...

Sumario:In order to seek novel technetium-99m bacterial infection imaging agents, a ciprofloxacin xanthate (CPF2XT) was synthesized and radiolabeled with [(99m)TcN](2+) core to obtain the (99m)TcN-CPF2XT complex, which exhibited high radiochemical purity, hydrophilicity, and good stability in vitro. The bacteria binding assay indicated that (99m)TcN-CPF2XT had specificity to bacteria. A study of biodistribution in mice showed that (99m)TcN-CPF2XT had a higher uptake in bacterial infection tissues than in turpentine-induced abscesses, indicating that it could distinguish bacterial infection from sterile inflammation. Compared to (99m)TcN-CPFXDTC, the abscess/blood and abscess/muscle ratios of (99m)TcN-CPF2XT were higher and the uptakes of (99m)TcN-CPF2XT in the liver and lung were obviously decreased. The results suggested that (99m)TcN-CPF2XT would be a potential bacterial infection imaging agent.
