Abstract

The products of the reaction between [Pt(dien)Cl]Cl and salmon sperm DNA have been purified and their structures determined. [Pt(dien)Cl]Cl binds at the N7 position of guanine for levels of fixation below 0.1 platinum per DNA base. Above this level of binding, [Pt(dien)Cl]Cl also reacts at the N7 position of adenine. 1,7-[Pt(dien)]2Ade was observed when more than 0.3 platinum per base were bound to the DNA. Platination at the N7 position of guanosine, unlike alkylation, stabilized the glycosyl linkage and did not lead to fission of the imidazole ring at high pH.
