Mixed-ligand metal (II) (M=Cu, Fe, Co and Zn) complexes containing
2-butanone thiosemicarbazone
and 1, 10-phenanthroline have been synthesized and characterized by melting point, FT-IR,
1
H-NMR, UV-spectrophotometry and molar conductance measurements. All the complexes were soluble in DMSO and DMF. They were thermally stable with high melting points. The computational studies of the complexes were also performed to assess toxicity potential, bioactivity score prediction and drug likeliness assessment based on various drug filters. All the complexes showed no Veber's violations whereas only Cu complex showed one Lipinski's violation. Almost all synthesized compounds were predicted to have no toxic effects. Some of them showed positive bioactivity as enzyme inhibitors. Molecular docking of the complexes was also performed against ribonucleotide diphosphate reductase (RR) and
topoisomerase
II (Topo II) for minimum binding energy (kcal/mol) calculations. Cu complex was found to have minimum binding energy (-101.13 kcal/mol) released on interaction with Topo II showing a high affinity towards the enzyme, whereas Fe complex had the lowest binding energy (-99.8349 kcal/mol) when docked with RR. The results were compared with two standard drugs i.e. doxorubicin HCl and tetracycline. The ligand was tested for its potential anticancer activity against MDA-MB-231 cell line using MTT assay. Antibacterial activity of the complexes was tested against
Staphylococcus aureus
and
Escherichia coli
using the disc diffusion method. Cu (II) complex showed maximum activity against the MDA cells and also exhibited mild antibacterial activity against
S. aureus
