X-ray photoelectron spectroscopy of DNA-Pt complexes. Evidence of O6 (Gua)-N7 (Gua) chelation of DNA with cis- dichlorodiamine platinum(II)

Abstract

The binding energies of nitrogen, oxygen, phosphorus, chlorine and Pt in several DNA - Pt (II) complexes are reported and discussed. The nitrogen band of DNA is slightly shifted upon complexation with Pt. Oxygen binding energies in the complexes studied clearly show that cis-Pt(NH3)2Cl2 forms a specific chelate N7(Gua) - O6 (Gua) with DNA as opposed to trans-Pt(NH3)2Cl2 and the other Pt compounds which react only with the N7(Gua) site of DNA.
