© 2022 Elsevier B.V.In the present work, we introduce new transition metal complexes. The complexes are designed to have 3,4,5-trimethoxyphenyl and 2‑hydroxy-4-methoxyphenyl groups connected by 1,2,4-triazole ring and imine linkage to be proper analogues for the anti-tubulin agent combretastatin A-4. FT-IR, 1H NMR, 13C NMR, mass spectrometry, CHNS, thermal gravimetric analysis (TGA-DSC), magnetic susceptibility, conductivity measurements, UV–Vis spectrophotometry, and flame atomic absorption spectroscopy have been used for the characterization of the synthesized compounds. The observed analytical and spectral data confirmed the octahedral environment around cobalt(II), platinum(IV) and square planar around nickel(II), copper(II) and palladium(II) ions. The antioxidant activity of the synthesized complexes was assessed by the DPPH assay, the obtained results showed that C4 is the most active one, with a scavenging capacity of 87.6% in comparison with ascorbic acid as a reference antioxidant agent at 50 µg/mL. The new metal complexes were screened for anticancer activity by the MTT assay against the breast cancer cell line MCF-7 and normal cell line WRL-68. The obtained results revealed that the lowest IC50 24.38 µM was recorded for palladium complex (C4) against the cancer cell line MCF-7,and an IC50 value of 90.2 µM against the normal cell line WRL-68. The synthesized compounds were also subjected to theoretical DFT studies, the obtained results came in agreement with the experimental results. The new ligand and its metal complexes were subjected to molecular docking studies, the structures were docked with the colchicine binding site (PDB: 1SA0), and good docking scores were recorded.
