  discovered. Targeted radionuclide therapy concentrates the effects on tumor cells, thereby increasing the efficacy and decreasing the morbidity of radiotherapy. In this context, analogues of N-(2-diethylaminoethyl)-4-iodobenzamide (BZA) are of interest. Various (hetero)aromatic analogues 5 of BZA were synthesized and radioiodinated with (125)I, and their biodistribution in melanoma-bearing mice was studied

  使用对黑素瘤组织具有特定亲和力的放射性碘化化合物的靶向放射性核素治疗是弥散性黑素瘤的一种有前途的治疗方法，但具有理想动力学特征的候选药物仍有待发现。靶向放射性核素疗法集中了对肿瘤细胞的作用，从而提高了疗效并降低了放射疗法的发病率。在这种情况下，N-（2-二乙基氨基乙基）-4-碘代苯甲酰胺（BZA）的类似物是令人关注的。合成了多种BZA的（杂）芳族类似物5并用（125）I进行了放射性碘标记，并在静脉注射后研究了它们在荷黑素瘤小鼠中的生物分布。大多数[（125）I] 5标记的化合物似乎与黑素瘤肿瘤特异性结合并且具有中到高亲和力。5h和5k这两种化合物，

  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.
