The resulting heterobimetallic complex exhibits favorable solubility and stability properties in biologically relevant media. It also shows in vitro cytotoxicity in line with that expected for this type of metallodrug, and is nontoxic to the organism as a whole. As a proof of concept, initial studies in healthy mice were performed to obtain information about the uptake, biodistribution, and excretion
提出了一种新颖的Ru II(芳烃)治疗学复合物。它基于带有三芳基膦的1,4,7,10-四氮杂环十二烷-1,4,7,10-四乙酸大环,并且可以通过使用153 Sm原子的γ辐射进行体内追踪。值得注意的是,尽管存在其他易于发生金属配位的官能团,但异二位配体可以在磷原子上用钌选择性地金属化。随后用放射性核素标记,例如153然后可以轻松执行Sm。所得的异双金属配合物在生物学相关的介质中显示出有利的溶解性和稳定性。它还显示出与此类金属药物预期的体外细胞毒性,并且对整个生物体无毒。作为概念的证明,在健康小鼠中进行了初步研究,以获得有关放射性标记复合物的摄取,生物分布和排泄的信息。
