PG - 14064-7 LID - 10.1039/c5cc05257b [doi] AB - In order to systematically investigate the influence of carrier ligands on the interaction of Pt-DNA adducts with damage recognition proteins, a series of DNA probes containing 1,2-GG platinum compound crosslinks using cisplatin, oxaliplatin, (S,S-DACH)PtCl2 and (cis-1,4-DACH)PtCl2 (kiteplatin) has been constructed. These complexes share similar DNA binding properties although they exhibit quite different cytotoxicity. It is revealed that HMGB1 (high-mobility group protein B1) was the most commonly found protein that recognizes all Pt(II)-DNA probes and prefers cisplatin-DNA probes more than the others. Interestingly, an important component of the replication protein A complex, RPA2, was found to bind to kiteplatin much more tightly than other proteins. These results may be important for the interpretation of the roles of carrier ligands in platinum(II)-based anticancer complexes.
