  Single Photon Emission Computed Tomography/Positron Emission Tomography Imaging and Targeted Radionuclide Therapy of Melanoma: New Multimodal Fluorinated and Iodinated Radiotracers

  摘要：

  This study reports a series of 14 new iodinated and fluorinated compounds offering both early imaging (I-123, I-124, F-18) and systemic treatment (I-131) of melanoma potentialities. The biodistribution of each I-125-labeled tracer was evaluated in a model of melanoma B16F0 bearing mice, using in vivo serial gamma scintigraphic imaging. Among this series, [I-125]56 emerged as the most promising compound in terms of specific tumoral uptake and in vivo kinetic profile. To validate our multimodality concept, the radiosynthesis of [F-18]56 was then optimized and this radiotracer has been successfully investigated for in vivo PET imaging of melanoma in B16F0- and B16F10-bearing mouse model. The therapeutic efficacy of [I-131]56 was then evaluated in mice bearing subcutaneous B16F0 melanoma, and a significant slow down in tumoral growth was demonstrated. These data support further development of 56 for PET imaging (F-18, I-124) and targeted radionuclide therapy (I-131) of melanoma using a single chemical structure.
