A series of tetrasubstituted naphthalene diimide compounds with N-methylpiperazine end groups has been synthesized and evaluated as G-quadruplexligands. They have high affinity and selectivity for telomeric G-quadruplexDNA over duplex DNA. CD studies show that they induce formation of a parallel G-quadruplex topology. They inhibit the binding of hPOT1 and topoisomerase IIIα to telomeric DNA and inhibit
