Cancer cell metabolism as new targets for novel designed therapies.

Metabolic processes are altered in cancer cells, which obtain advantages from this metabolic reprogramming in terms of energy production and synthesis of biomolecules that sustain their uncontrolled proliferation. Due to the conceptual progresses in the last decade, metabolic reprogramming was recently included as one of the new hallmarks of cancer. The advent of high-throughput technologies to amass an abundance of omic data, together with the development of new computational methods that allow the integration and analysis of omic data by using genome-scale reconstructions of human metabolism, have increased and accelerated the discovery and development of anticancer drugs and tumor-specific metabolic biomarkers.

Cyclopalladated primary amines: a preliminary study of antiproliferative activity through apoptosis induction.

Twelve cyclometallated palladium(II) complexes containing primary aromatic amines [benzylamine (a), (R)-1-(1-naphthyl)ethylamine (b) and 2-phenylaniline (c)] as anionic bidentate (C,N)(-) ligands have been evaluated against a panel of human adenocarcinoma cell lines (A549 lung, MDA-MB231 and MCF7 breast, and the cisplatin resistant HCT116 colon). The results revealed a remarkable antiproliferative activity of the triphenylphosphane mononuclear compounds 3-4 (series a, b, c) and the best inhibition was provided for 3c and 4c with the 2-phenylaniline ligand and a six membered chelate ring. Interestingly, 3c and 4c were 14 and 19 times more potent than cisplatin for the inhibition of the cisplatin resistant HCT116 human adenocarcinoma cell line, respectively.
