DNA binding, anti-urease activity, and anticancer effects were evaluated through density functional theory, molecular docking, UV-visible and fluorescence spectroscopy, cyclic voltammetry, and viscometry.

The structural characterization of the derivatives was carried out by FTIR, 1H-NMR, and 13C-NMR, and then their DNA binding, anti-urease, and anticancer activities were explored. Both theoretical and experimental results, as obtained by density functional theory, molecular docking, UV-visible spectroscopy, fluorescence (Flu-)spectroscopy, cyclic voltammetry (CV), and viscometry, pointed towards compounds' interactions with DNA.
