Mechanistic information on the reaction of model palladium(II) complexes with purine nucleosides and 5′-nucleotides in reference to the antitumor activity of related platinum complexes
摘要:
The reaction of Pd(Me,en)Cl2 (Me4en=NNN',N'-tetramethylethylenediamine) with inosine and 5'-inosine monophosphate was studied as a function of chloride concentration and pH. Evidence for the formation of a 1:1 complex with these nucleophiles is presented, and the kinetic data indicate that Pd(Me4en)(Cl)H2O+ is the only reactive species under the selected experimental conditions. The results are compared to earlier data for the reactions of Pd(R4en)(H2O)22+ (R = H, Me, Et) with a series of nucleosides and 5'-nucleotides. The dependencies studied in this investigation allow some tentative extrapolations to conditions relevant for the antitumor activity of related Pt(II) complexes.

Interaction of kiteplatin with S-donors is investigated. Kiteplatin–glutathione adducts can further react with 5′-GMP in presence of O2. This unique reaction may account for its activity toward oxaliplatin-resistant colon cancer.

group cisG N1H hydrogenbonding favors the ΛHT and the ΔHT conformers for 5′-GMP and 3′-GMP adducts, respectively. For both HT conformers of cis-PtA2G2 adducts, the G nucleobase plane normally cants with respect to the coordination plane in the same direction, left or right, for a given A2 chirality. In contrast, the results for Me4DABPtG2 adducts provide the first examples of a change in the canting
