Journal ArticleDOI
Gold dithiocarbamate derivatives as potential antineoplastic agents: design, spectroscopic properties, and in vitro antitumor activity.
Luca Ronconi,Lorena Giovagnini,Christine Marzano,Frazia Bettio,Rodolfo Graziani,Giuseppe Pilloni,Dolores Fregona +6 more
TL;DR: Gold(III) derivatives of N,N-dimethyldithiocarbamate and ethylsarcosinedithiOCarbamate have been proved to be much more cytotoxic in vitro than cisplatin, with IC50 values about 1- to 4-fold lower than that of the reference drug, even toward human tumor cell lines intrinsically resistant to cis platin itself.
Journal ArticleDOI
A Novel Anticancer Gold(III) Dithiocarbamate Compound Inhibits the Activity of a Purified 20S Proteasome and 26S Proteasome in Human Breast Cancer Cell Cultures and Xenografts
TL;DR: The proteasome is revealed as a primary target for gold(III) dithiocarbamates and support the idea for their potential use as anticancer therapeutics.
Journal ArticleDOI
Gold(III) dithiocarbamate derivatives for the treatment of cancer: solution chemistry, DNA binding, and hemolytic properties.
Luca Ronconi,Christine Marzano,Piero Zanello,Maddalena Corsini,Giorgia Miolo,Carlo Maccà,and Andrea Trevisan,Dolores Fregona +7 more
TL;DR: These gold(III) complexes show high reactivity toward some biologically important isolated macromolecules, resulting in a dramatic inhibition of both DNA and RNA synthesis and inducing DNA lesions with a faster kinetics than cisplatin, suggesting that intracellular DNA might not represent their primary or exclusive biological target.
Journal ArticleDOI
Synthesis, Characterization, and Comparative in Vitro Cytotoxicity Studies of Platinum(II), Palladium(II), and Gold(III) Methylsarcosinedithiocarbamate Complexes
Lorena Giovagnini,Luca Ronconi,Donatella Aldinucci,Debora Lorenzon,Sergio Sitran,Dolores Fregona +5 more
TL;DR: Experimental results show [Pd(MSDT)X]n (MSDT = methylsarcosinedithiocarbamate; X = Cl, Br) complexes show a strong dose-dependent growth inhibition of both HL60 and HeLa cells, with IC(50) values slightly higher than those recorded for cisplatin.
Journal ArticleDOI
Chemistry, antiproliferative properties, tumor selectivity, and molecular mechanisms of novel gold(III) compounds for cancer treatment: a systematic study
Angela Casini,Gerhard Kelter,Chiara Gabbiani,Maria Agostina Cinellu,Giovanni Minghetti,Dolores Fregona,Heinz H. Fiebig,Luigi Messori +7 more
TL;DR: The results conclusively qualify gold(III) compounds as a promising class of cytotoxic agents, of outstanding interest for cancer treatment, while providing initial insight into their modes of action.
