Synthesis, characterization, structure, molecular modeling studies and biological activity of sterically crowded Pt(II) complexes containing bis(imidazole) ligands

J Inorg Biochem. 2011 Mar;105(3):400-9. doi: 10.1016/j.jinorgbio.2010.12.002. Epub 2010 Dec 14.

Abstract

The syntheses, structures and biological evaluation of a series of cisplatin-like complexes containing bis(imidazole) derivatives - the so-called Joseph ligands - are described. Their cytotoxicity is discussed in terms of their polar surface area, rate of aquation, and lipophilicity. The X-ray crystal structure of the platinum diiodido derivative of dimethyl 2-(di(1H-imidazol-2-yl)methyl)malonate) is reported and compared to those of related systems. Molecular modeling studies are focused on the hydrogen bonding properties of such systems, and their relevance to antitumor activity.
