摘要
In the present study, we investigated the anticancer action of the trithiolato arene ruthenium complex, [(eta(6)-p-MeC6H4Pri)(2)Ru-2(mu-S-p-C6H4OH)(3)]Cl, named diruthenium-2, both in vitro and in vivo. The mechanism of antiproliferative, cytotoxic, and DNA-damaging activity, and the effect on expressions of cell cycle regulatory proteins were investigated using a WST-1-based proliferation assay, lactate dehydrogenase leakage assay, comet assay, flow cytometry, and western blot analysis. In-vivo anticancer activity was evaluated using Ehrlich tumor-bearing NMRI mice. Diruthenium-2 inhibited the growth of all cancer cell lines used, the most sensitive being gastric (AGS), breast cancer (BT-549, MCF-7, MDA-MB-231), and leukemic (HL-60, MOLT-4) cells. In MCF-7 cells, it caused a G1/S cell cycle arrest, along with an increase in the expression of protein p21 and cyclin B1. We also observed increased levels of MRN complex proteins, which, together with the results from the comet assay, indicate the formation of DNA double-strand breaks. In tumor-bearing mice, diruthenium-2 at doses of 3 and 5 mg/kg inhibits the growth of solid Ehrlich tumor, although weaker than cisplatin. However, it did not prolong the post-therapeutic survival. Our results suggest the in-vitro potential of diruthenium-2 should be further evaluated in studies using other in-vivo models. Copyright (C) 2016 Wolters Kluwer Health, Inc. All rights reserved.
