Selective Recognition of G-Quadruplex by Structural Tuning of Heteroaromatic Scaffolds and Side Chains
Overview
Affiliations
In this study, carbazole () and dibenzofuran () derivatives were synthesized to examine their effect on the biomolecular recognition of G-quadruplex (G4) targets. Biophysical studies revealed that , a carbazole derivative, exhibits a specific affinity and effectively stabilizes the G4. Molecular modeling suggests a stable interaction of with the terminal G-tetrad of G4. Biological studies demonstrate that efficiently enters cells, reduces gene expression, and induces cell cycle arrest, DNA damage, and apoptosis in cancer cells. These findings demonstrate as a selective G4 ligand with therapeutic potential, providing insight into the structural basis of its anticancer mechanisms.
