N2 - Conformational properties of DNA molecule upon its complexation with binuclear compounds of bivalent platinum in the cis configuration containing pyrazine ligand were studied by circular dichroism, viscometry, and dynamic birefringence. Comparison with active antitumor therapeutic cis-diamminedichloroplatinum (cis-DDP) was made. Experimental data indicates that interaction of these compounds with DNA results in the formation of coordination bond of platinum with nitrogen bases. The structure of the complex depends on the ratio of platinum and DNA concentrations in initial solution. The study of DNA protonation in complex with the binuclear coordination compound showed that the binding of platinum with DNA bases occurs at the N7 atom of guanine. It was observed a competition between the studied compound and cis-DDP for binding site on DNA. The macromolecule binds stronger to the binuclear platinum compound as compared with cis-DDP.
