Abstrakt:	The use of chemotherapeutics has achieved considerable success in cancer therapy; however, their toxicity can severely impact patients' health. In this study, aiming to reduce the doses and potential side effects of traditional chemotherapeutics, we systematically treated A375MM human melanoma cells with seven clinically approved antineoplastic drugs, in combination with three well-characterized G-quadruplex (G4) ligands, using either simultaneous or sequential dosing schedules. Interestingly, the G4 binders synergized with most of the investigated anticancer drugs, with the degree of synergism being strictly dependent on both the treatment schedule and the drug sequence employed. Notably, some of the synergistic combinations showed selective toxicity toward melanoma cells over nontumorigenic human keratinocytes. Furthermore, immunofluorescence experiments highlighted the potential implication of G4 structures in the molecular mechanisms driving the synergistic interaction between some chemotherapeutics and G4 binders. Overall, our systematic study supports the combination of G4-interacting molecules with standard antineoplastic drugs as a promising antitumor strategy. (© The Author(s) 2024.
