摘要
The reactions of plasmid DNA modified with the novel acridinylthiourea, 1-[2-(acridin-9-ylamino)ethyl]-1,3-dimethylthiourea (1), and the corresponding intercalator-tethered platinum complex (2) with human type I and type II topoisomerases have been studied. Assays were based on evaluating DNA cleavage products resulting from incubations of drug-modified DNA in cell-free systems. 2 produces double-strand breaks in the presence of topo II while 1 proved to be a dual topo I/topo II poison.
