Dinuclear Ruthenium Complexes as Sequence- and Structure-Selective Binding Agents for DNA

点击翻译按钮获取中文摘要

Studies of the interaction of mononuclear metal complexes with DNA have greatly increased our understanding of the ways that small molecules recognise particular sites on DNA. However, in order to design drugs that target specific genes, and hence be potentially capable of controlling gene expression, it is necessary to study the binding of metal complexes that can associate with larger segments of DNA. Using the combined expertise of the applicants, it is proposed to stereospecifically synthesise dinuclear complexes and study their DNA binding. This will greatly assist in the development of drugs that can selectively target genes and altered DNA.
