Abstract:

G-quadruplex structure is a four-stranded form of DNA, which is associated with cancer cell proliferation. G-quadruplexstabilized ligands have the potential to interfere with telomere replication by blocking the elongation procedure catalyzed by telomerase, and therefore have the potential to be anti-cancer drugs. A considerable number of novel compounds capable of targeting G-quadruplex at high affinity and specificity have been reported. Among them, several G-quadruplex ligands have shown promising anti-cancer activity in tumor xenograft models, and entered phase II clinical trials on cancer patients. This review summarized recent developments of Gquadruplex ligands as anti-cancer drugs and several powerful strategies to discover novel G-quadruplex ligands as anti-cancer drug candidates by screening natural product extracts and structural optimization of previously identified typical compounds.
