  Synthesis, Radiofluorination, and in Vivo Evaluation of Novel Fluorinated and Iodinated Radiotracers for PET Imaging and Targeted Radionuclide Therapy of Melanoma

  摘要：

  Our project deals with a multimodal approach using a single fluorinated and iodinated melanin-targeting structure and offering both imaging (positron emission tomography (PET)/fluorine-18) and treatment (targeted radionuclide therapy/iodine-131) of melanoma. Six 6-iodoquinoxaline-2-carboxamide derivatives with various side chains bearing fluorine were synthesized and radiofluorinated, and their in vivo biodistribution was studied by PET imaging in B16B16 primary melanoma-bearing mice. Among this series, [F-18]8 emerged as the most promising compound. [18F]8 was obtained by a fully automated radiosynthesis process within 57 min with an overall radiochemical yield of 21%, decay-corrected. PET imaging of [18F]8 demonstrated very encouraging results as early as 1 h postinjection with high tumor uptake (14.33% +/- 2.11% ID/g), high contrast (11.04 +/- 2.87 tumor-to-muscle ratio), and favorable clearance properties. These results, associated with the previously reported pharmacokinetic properties and dosimetry of 8, make it a potential agent for both PET imaging and targeted radionuclide therapy of melanoma.
