Abstract
The Cu(II) and Zn(II) complexes were synthesized using Schiff base ligand by refluxing with CuCl2 and ZnCl2. A Schiff base ligand (L) was synthesized by condensing o-vanillin and 4-aminoantipyrine. The synthesized ligand and metal complexes were characterized by IR and mass spectrometry. The synthesized Cu(II) and Zn(II) metal complexes were especially docked with human DNA (PDB I.D: 1BNA) and dengue protein virus (PDB ID: 2VBC) using auto dock software tools version 1.5.6 and pymol. The binding of the ligand and biomolecule in grid point value of x × y × z directions of 90 × 90 × 90 and a grid space group value of 0.380 Å. The binding energy values of Cu(II) and Zn(II) complexes were respectively -7.1 and -7.4 kcal mol–1 towards NS3 protease-helicase, while the binding energy values of Cu(II) and Zn(II) complexes were found to be -8.5 and -8.2 kcal mol–1, respectively towards B-DNA.
