This article is an open access article about a Pt(II) terpyridine complex and its interaction and binding mode with DNA.
The studies showed that the complex can enter the cell nucleus and interact with DNA in a non-covalent manner. They also found that the complex has a selective cytotoxicity towards certain cancer lines.
I have been trying to follow metal complex-DNA interaction papers. But, looks like I missed this one. It's a great study. But, I would like to know why there is no x-ray data.
