ABSTRACT
Two oxovanadium(IV) complexes of [VO(msatsc)(phen)], (1) (msatsc = methoxylsalicylaldehyde thiosemicarbazone, phen = phenanthroline) and its novel derivative [VO (4-chlorosatsc)(phen)], (2) (4-chlorosatsc = 4-chlorosalicylaldehyde thiosemicarbazone), have been synthesized and characterized by elemental analysis, IR, ES-MS, (1)H NMR, and magnetic susceptibility measurements. Their antitumor effects on BEL-7402, HUH-7, and HepG2 cells were studied by MTT assay. The antitumor biological mechanism of these two complexes was studied in BEL-7402 cells by cell cycle analysis, Hoechst 33342 staining, Annexin V-FITC/PI assay, and detection of mitochondrial membrane potential (ΔΨm). The results showed that the growth of cancer cells was inhibited significantly, and complexes 1 and 2 mainly caused in BEL-7402 cells G0/G1 cell cycle arrest and induced apoptosis. Both 1 and 2 decreased significantly the ΔΨm, causing the depolarization of the mitochondrial membrane. Complex 2 showed greater antitumor efficiency than that of complex 1.

DNA content and cell cycle analysis of BEL-7402 cells after complex 2 treatment. BEL-7402 cells were cultured with either 0.1% DMSO (control), 30 μM, 60 μM, and 120 μM of complex 2 for 48 h. The percentage of nonapoptotic cells within each cell cycle was determined by flow cytometry.

Mentions: In order to elucidate the mechanisms underlying the observed antiproliferative effect of complexes 1 and 2 on cancer cells, the cells cycle distribution was analyzed by flow cytometry with PI staining [17, 33–39]. The BEL-7402 cells were treated with 30 μM, 60 μM, and 120 μM of 1 and 2 for 48 h, respectively. The results were shown in Figures 5 and 6. According to the results of Figures 5 and 6, it indicated that there were significantly increased rates of cells at G0/G1 phase and decreased the rates of cells at S and G2/M phase after BEL-7402 cells were exposed to 1 and 2 compared with untreated cells.
