The present invention relates to compounds and related technetium and rhenium complexes thereof which are suitable for imaging or therapeutic treatment of tumors, e.g., carcinomas, melanomas and other tumors. In another embodiment, the invention relates to methods of imaging tumors using radiolabeled metal complexes. Preferred radiolabeled complexes for imaging tumors include technetium and rhenium complexes. The high tumor uptake and significant tumor/nontumor ratios of the technetium complexes of the invention indicate that such small technetium-99m-based molecular probes can be developed as in-vivo diagnostic agents for melanoma and its metastases. In yet another embodiment, the invention relates to methods of treatment of tumors using a radiolabeled metal complex as a radiopharmaceutical agent to treat the tumor.
本发明涉及化合物及其相关的锝和铼配合物,适用于肿瘤的成像或治疗,例如癌瘤、黑色素瘤和其他肿瘤。在另一实施方式中,本发明涉及使用放射标记金属配合物成像肿瘤的方法。用于肿瘤成像的首选放射标记配合物包括锝和铼配合物。本发明的锝配合物具有高肿瘤摄取率和显著的肿瘤/非肿瘤比,表明这种基于锝-99m的小分子探针可以作为黑色素瘤及其转移的体内诊断试剂。在另一实施方式中,本发明涉及使用放射标记金属配合物作为放射药剂来治疗肿瘤的方法。
