Abstract

Targeting of DNA secondary structures, such as G-quadruplexes, is now considered an appealing opportunity for drug intervention in anticancer therapy. So far, efforts made in the discovery of chemotypes able to target G-quadruplexes mainly succeeded in the identification of a number of polyaromatic compounds featuring end-stacking binding properties. Against this general trend, we were persuaded that the G-quadruplex grooves can recognize molecular entities with better drug-like and selectivity properties. From this idea, a set of small molecules was identified and the structural features responsible for G-quadruplex recognition were delineated. These compounds were demonstrated to have enhanced affinity and selectivity for the G-quadruplex over the duplex structure. Their ability to induce selective DNA damage at telomeric level and to induction of apoptosis and senescence on tumor cells is herein experimentally proven.
