  Re（CO）3胸苷配合物的合成，细胞毒性和作用方式的见解。

  摘要：

  核苷类似物被广泛用于癌症和病毒性疾病的治疗。迄今为止，几乎没有研究过有机or（I）配合物的抗增殖特性。在这里，我们介绍胸苷和尿苷的Re I（CO）3核心配合物的合成，表征和体外评估。用于绑定Re I（CO）3作为核心，在位置C5'，C2'，N3和C5处引入具有不同长度间隔基的三齿二聚二烯丙基胺金属螯合物。相应的有机金属胸苷配合物通过IR和NMR光谱法和质谱法充分表征。评估了它们对A549肺癌细胞系的细胞毒性。毒性取决于结合的部位和方式，以及系链的性质和长度。观察到用于承载铼部分在位置C5'或N3缀合物中等毒性（IC 50 = 124-160μ中号）。对于在C2'或C5处修饰的复合物，未观察到毒性。在C5'处带有十二碳烯间隔基的配合物53具有显着的毒性，并且比顺铂更有效，IC 50为50的6.0μ值中号。据我们所知，这是[M（CO）3 ] + 1-核苷结合物的抗增殖特性的首次报道。在使用A5

  A series of novel thymidine dithiocarbamate derivatives (DTC-TdR) were successfully synthesized and then radiolabelled using [Tc-99m(CO)(3)](+) core with high yields. The chemical characterizations of Tc-99m(CO)(3)-labelled dithiocarbamate derivatives have been carried out by preparing their corresponding rhenium complexes. The radiotracers were stable in vitro, and the partition co efficient results indicated that they were lipophilic. The cell uptake studies showed the uptakes of these(99m)Tc(CO)(3)-labelled thymidine derivatives were mediated by nucleoside transporters. Biodistribution of the complexes in mice bearing tumor showed that they had high tumor uptake and good tumor/muscle ratio. A clear SPECT imaging of the tumor location was obtained in mice bearing S180 tumor with one of radiotracers, suggesting they would be potential tumor imaging agents. (C) 2018 Elsevier B.V.

  Human cytosolic thymidine kinase (hTK1) has proven to be a suitable target for noninvasive imaging of cancer cell proliferation using radiolabeled substrates such as [F-18]fluorothymidine ([F-18]FLT). However, a thymidine tracer useful for single photon emission tomography (SPECT) based off the inexpensive radionuclide technetium-99m would be of significant interest. In this work, a series of thymidine derivatives labeled with the organometallic [M(CO)(3)](+) core (M = Tc-99m, Re) were synthesized. Neutral, cationic, and anionic complexes were readily formed in aqueous media. and all were substrates of recombinant hTK1 when incubated with ATP. The neutral complexes were phosphorylated to a greater extent than the charged complexes. The extent of phosphorylation was further improved by increasing the spacer length separating thymidine and the organometallic core. A molecular dynamics Simulation Study performed with a modified hTK1 structure Supported the experimental findings. In vitro cell internalization experiments performed if) a human neuroblastoma cell line (SKNMC) showed low uptake of the charged complexes but significant uptake for the neutral, lipophilic complexes with a log P value > 1.
