Abstract
Anti-cancer effects of a newly-synthesized palladium(II) complex, [Pd(sac)(terpy)](sac)·4H 2O (sac = saccharinate, and terpy = 2,2′:6′,2″-terpyridine), were tested against human breast cancer cell lines, MCF-7 and MDA-MB-231. The Pd complex had a strong anti-growth effect in a dose- and time-dependent manner in vitro. This effect was also confirmed by the experiment performed on Balb/c mice in vivo. The IC 50 values were 0.09 μM for MDA-MB-231 and 3.05 μM for MCF-7. It was also very effective in disrupting the formation of MDA-MB-231 tubules on matrigel, indicative of a putative anti-invasive activity. It induced apoptosis via the cell death genes of DR4 and DR5. In conclusion, this newly-synthesized Pd (II) complex represents a potentially active novel drug for the breast cancer treatment.
