Pt(II) complexes bind preferentially at N7 of G residues of DNA, causing DNA structural distortions associated with anticancer activity. Some distortions induced by difunctional cisplatin are also found for monofunctional Pt(II) complexes with carrier ligands having bulk projecting toward the guanine base. This ligand bulk can be correlated with impeded(More)
Monofunctional Pt(II) complexes bind to G residues in DNA and, if the carrier ligands are bulky, cause DNA structural distortions that lead to anticancer activity. We assessed the steric effects of the tridentate carrier ligand, N(H)6-Medpa (N-(6-methyl-2-picolyl)-N-(2-picolyl)amine), bearing a 6-methyl group and a 6'-proton projecting toward the nucleobase(More)
Anticancer-active monofunctional Pt(II) complexes have bulky carrier ligands and bind to G residues in DNA, causing structural distortions. To gain fundamental chemical information on such monofunctional adducts, we assessed the 9-ethylguanine (9-EtG) adducts formed by [Pt(N(H)6,6'-Me2dpa)Cl]Cl (N(H)6,6'-Me2dpa = di-(6-methyl-2-picolyl)amine). 9-EtG added(More)
