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-
