The synthesis, photophysical properties, DNA binding, DNA cleavage and cellular imaging behaviour of a range of complexes of the type [Re(CO)3(dppz)(PyR)]+ are reported, where PyR represents a range of substituted pyridines which have previously been studied for cellular localisation of related complexes. Confocal imaging experiments confirm that the complexes retain the variety of cellular localisation behaviour associated with the PyR units in other complexes, and suggest applications as probes for oligonucleotides in specific cellular compartments (e.g. mitochondrial DNA). This study illustrates the importance of considering cellular localisation as a prime consideration in the design of probes for in vivo application.
报告了一系列[Re(CO)3(dppz)(PyR)]+ 型复合物的合成、光物理性质、DNA 结合、DNA 裂解和细胞成像行为,其中 PyR 代表一系列取代的
吡啶,以前曾对相关复合物的细胞定位进行过研究。共焦成像实验证实,这些复合物保留了与其他复合物中 PyR 单元相关的各种细胞定位行为,并建议将其用作特定细胞区(如线粒体 DNA)中寡核苷酸的探针。这项研究表明,在设计用于体内应用的探针时,将细胞定位作为首要考虑因素非常重要。
