英文摘要:

Achieving a Tc-99m-labeled fluoroquinolone derivative as a single photon emission computed tomography (SPECT) tracer is considered to be of great interest. The norfloxacin dithiocarbamate (NFXDTC) was synthesized and radiolabeled with a [(TcN)-Tc-99m](2+) intermediate to form the (TcN)-Tc-99m-NFXDTC complex in high yield. The radiochemical purity of (TcN)-Tc-99m-NFXDTC was over 90%, as measured by thin layer chromatography (TLC) and high performance liquid chromatography (HPLC), without any notable decomposition at room temperature over a period of 6 h. The partition coefficient and electrophoresis results indicated that (TcN)-Tc-99m-NFXDTC was lipophilic and neutral. The bacterial binding assay studies showed tht (TcN)-Tc-99m-NFXDTC had a good binding affinity. Biodistribution results in bacterial infected mice showed that (TcN)-Tc-99m-NFXDTC had a higher uptake at the sites of infection and better abscess/blood and abscess/muscle ratios than those of Tc-99m-ciprofloxacin and (TcN)-Tc-99m-CPFXDTC (CPFXDTC = ciprofloxacin dithiocarbamate). The biodistribution results of (TcN)-Tc-99m-NFXDTC in bacterially infected mice and in mice with turpentine-induced abscesses indicated that (TcN)-Tc-99m-NFXDTC was suited to be a bacteria-specific infection imaging agent. Single photon emission computed tomography (SPECT) image studies showed there was a visible accumulation in infection sites, suggesting that it would be a promising candidate for bacterial infection imaging.
