原始语种摘要: Abstract(#br)In this study, three transition metal compounds based on benzimidazole-quinoline ligand [Cu(pbmq)Cl 2 ] 2 (1) , [Cu(pbmq)Br 2 ] 2 (2) , and Pt(pbmq)Cl 2 (3) (where pbmq = 2-((2-(pyridin-2-yl)-1H-benzo[ d ]imidazol-1-yl)methyl)quinolone), were synthesized and characterized. The compounds showed much higher cytotoxicity than pbmq against the tested human cancer cell lines. Notably, compound 1 exhibited marked anticancer activity against SMMC7721 cells. Hence, compound 1 was selected for further studies to understand the underlying mechanisms of its anticancer activity. Fluorescence, CD spectroscopy studies and viscosity determination showed that compound 1 could strongly bind to calf thymus DNA (CT-DNA). The CT-DNA binding properties revealed that intercalation might be the...
