Biaryl polyamides as a new class of DNA quadruplex-binding ligands

Chem Commun (Camb). 2009 Jul 21:(27):4097-9. doi: 10.1039/b902359c. Epub 2009 Jun 5.

Abstract

We report a novel class of biaryl polyamides highly selective for G-quadruplex DNA, and with significant cytotoxicity in several cancer cell lines; they form planar U-shaped structures that match the surface area dimensions of a terminal G-quartet in quadruplex structures rather than the grooves of duplex DNA.
