摘要

~1H NMR and LC-ESI-MS studies of the interaction between nucleosides (adenosine,cytidine,guanosine,uridine and thymidine) and a monocation platinum(II) complex [Pt(C-(6-aminomethylpyridin-2-yl)methylamine)Cl]~+ (1) shows it forms platinum(II) complexes with A,G and C at pH 6 and with T and U at pH 9.The X-ray structure of 1 as the hydrated chloride salt shows extensive hydrogen bonding.Amongst a series of related complexes 1 shows a strong interaction with DNA,demonstrated by inhibition of binding by the intercalator ethidium bromide,and moderate cytotoxicity.The interaction with nucleosides and the structural data suggest that 1 disrupts the DNA structure by coordinate covalent interaction and hydrogen bonding rather than simple intercalation.
