中文摘要long human telomeric fragments can form stable, higher-order g-quadruplex structures, recently identified in human cells, which are potential drug targets. however, there are very few examples of ligand binding to higher-order g-quadruplexes, and all the reported ligands are proposed to bind at the cleft between two g-quadruplexes. here we report that zinc-finger-like chiral supramolecular complexes prefer binding to higher-order g-quadruplexes over a single g-quadruplex, with similar to 200-fold higher selectivity. to our knowledge, this is the first example of a ligand that can distinguish higher-order g-quadruplexes from a single g-quadruplex with such high selectivity. further studies indicate that the nanosized chiral complex would bind to two well-matched g-quadruplex units, instead of binding at the cleft between the two g-quadruplexes. these results provide new insights into the targeting of higher-order g-quadruplex ligands. our work illustrates that dimeric g-quadruplex units can be ligand-preferred binding sites.
