Antiproliferative Ruthenium Complexes Containing Curcuminoid Ligands Tested In Vitro on Human Ovarian Tumor Cell Line A2780, towards Their Capability to Modulate the NF- κ BTranscription Factor, FGF-2 Growth Factor, and MMP-9 Pathway.

So far, the polyphenolic components of turmeric have shown a significant pharmacological preventative activity for a wide spectrum of diseases, including oncological disorders. This type of natural product could be of great interest for the inhibition of cancer cell proliferation, displaying less side effects in comparison to classical chemotherapeutics. The poor bioavailability and quick metabolism of such natural compounds require new investigative methods to improve their stability in the organisms. A synthetic approach to increase the efficiency of curcuminoids is to coordinate them to metals through the beta-dicarbonyl moiety. We report the synthesis and the biological attempts on human ovarian carcinoma A2780 of ruthenium(II) complexes 1 - 4 , containing curcuminoid ligands. The cytotoxicity of complexes 1 - 4 proves their antiproliferative capability, and a correlation between the IC 50 values and NF- κ B transcription factor, FGF-2, and MMP-9 levels was figured out through the principal component analysis (PCA).
