Abstract

Hydroxypyr(id)ones constitute an emerging platform for the design of drug molecules, owing to their favorable biocompatibility and toxicity profiles. Herein, [Ru

6-p-cymene)] complexes with 3-hydroxy-2-pyridinone functionalized with morpholine and thiomorpholine, as a means often used in medicinal chemistry to alter the physicochemical properties of drug compounds, are reported. The compounds underwent hydrolysis of the Ru@Cl bond and the aqua species were stable for up to 48 h in aqueous solution, as observed by 1H NMR spectroscopy and ESI-MS. The compounds formed adducts with amino acids and proteins through cleavage of the pyridinone ligand. Binding experiments to the nucleosome core particle by means of X-ray crystallography revealed similar reactivity and exclusive binding to histidine moieties of the histone proteins. Preliminary cyclin-dependent kinase 2 (CDK2)/cyclinA kinase inhibitory studies revealed promising activity similar to that of structurally related organometallic compounds.
