dc.description.abstract | In this work, one oxidomethoxidovanadium(V) [VVO(L)(OMe)] (1) and two mixed-ligand oxidovanadium(IV) [VIVO(L)(phen)] (2), and [VIVO(L)(bipy)] (3) complexes have been synthesized using a tridentate bi-negative ONS donor dithiocarbazate as main ligand, H2L [where, H2L = S-benzyl-3-(2-hydroxy-3-ethoxyphenyl)methylenedithiocarbazate] along with 1,10-phenanthroline (phen) (for 2) and 2,2′-bipyridine (bipy) (for 3) as co-ligands. The ligand and complexes have been characterised by FT-IR, UV-vis, NMR, and HR-ESI-MS techniques. Distorted square pyramidal for 1, and distorted octahedral geometry for 2 and 3 was confirmed by single crystal X-ray crystallography. The behavior of 1−3 in solution medium has been investigated through various physicochemical techniques.1 It is observed that 1 completely and 2−3 partially decomposes and converts into a penta-coordinated species, [VIVO(L)(DMSO/H2O)] after the release of the methoxido group (1) or breaking of the diimine based co-ligands (2 and 3) in DMSO/aqueous solution. Interestingly, in DMSO/aqueous solution, 1 gets completely reduced and converted into the corresponding oxidovanadium(IV) species.2 Interaction of 1−3 with calf thymus DNA (CTDNA) was investigated1 and the results show, complex 2 exhibited the maximum binding constants, Kb = 7.12 × 104 M−1. The anticancer potential of 1−3 was evaluated1,3 by cell viability assay against human breast carcinoma cell, MCF-7, and noncancerous mouse embryonic cell, NIH-3T3 and 2 was found to be the most cytotoxic complex (IC50 = 6.73 ± 0.36 M) in the series. In addition, 2 selectively inhibit colony formation compared to the rest complexes. Also, the cell cycle studies of the complexes were performed using flow cytometry analysis.3 | en_US |
