Abstract:

Four-stranded tetraplex (“G-quadruplex”) DNA represents a new paradigm for the design of DNA-interactive antitumour drugs, as the formed DNA-drug complexes have been suggested to interfere with critical telomerase function. The unique structural features presented by tetraplex over duplex DNA have stimulated the design of small ligand molecules able to selectively promote the formation and-or stabilisation of such higher-order DNA structures. Current developments in tetraplex-targeted telomerase inhibitors, and importantly their DNA structural selectivity, are explored.
