摘要
A number of N, N'-disubstituted perylenetetracarboxylic diimides have been reported to bind effectively to DNA that adopts G-quadruplex motifs. In some cases, this binding may actively drive the transition from single-strand DNA to the quadruplex form. The perylenediimides in the reported cases all have amine-containing side chains, which are thought to interact with the grooves of the quadruplex and help dictate the selectivity of these compounds for quadruplex versus duplex DNA. We synthesized a polyethyleneglycol-swallowtailed (PEG-tailed) perylenediimide that is water-soluble even though it is uncharged. Binding to duplex and quadruplex DNA of this perylenediimide was studied by fluorescence quenching titrations under a variety of salt conditions, and the compound's effect on quadruplex formation was studied by non-denaturing gel electrophoresis. Our results indicate that while the molecule binds to single-stranded DNA quite effectively and with selectivity, it does not drive the transition of the DNA to the tetrameric quadruplex structure, supporting the idea that charge neutralization is a key component of perylene compounds that stabilize tetrameric quadruplexes.
