DNA i-motif guided synthesis of a selective telomerase inhibitor

Abstract

Selective recognition of i-motif DNA remains challenging due to its pH-dependent dynamics. Here, we report an i-motif templated target-guided synthesis that enables regioselective in situ formation of a 1,4-triazolyl carbazole (BPTC), which exhibits high affinity and selectivity for telomeric i-motif over G-quadruplex and duplex DNA, leading to potent telomerase inhibition.
