The antioxidant properties of the newly synthesized compounds, 1a–1c, 2a–2c, and 3a–3c, were evaluated by monitoring DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging abilities, metal chelating effects, and reducing power. The scavenging effects of compounds on the free radical decreased in the order of 3b > 3a > 1b and were found to be 36.3%, 34.9%, and 27.6% at the concentration of 500 g/mL, respectively. All of the compounds showed low chelating capacity. Furthermore, the antibacterial activity was studied against gram-positive and gram-negative bacteria and the DNA binding ability of the compounds was evaluated with calf thymus DNA using agarose gel electrophoresis.eninfo:eu-repo/semantics/openAccessQuinoline, quinolone, triazole, antioxidant, antibacterialArticle4213581369
