title: Natural and synthetic G-quadruplex interactive berberine derivatives.
abstract: The interaction of the natural alkaloid berberine with various G-quadruplex DNA structures and its ability to inhibit telomerase have been examined and compared with those of a synthetic piperidino derivative and the related compound coralyne. The results show that these molecules have selectivity for G-quadruplex compared to duplex DNA, and that their aromatic moieties play a dominant role in quadruplex binding.
