There is considerable interest in DNA sequence-selective DNA-binding drugs as potential inhibitors of gene expression. Five compounds with distinctly different base pair specificities were compared in their effects on the formation and elongation of the transcription complex from the lac UV5 promoter in a cell-free system. All were tested at drug levels which killed 90% of cells in a clonogenic survival...
Cisplatin (DDP) is currently one of the most effective drugs for the treatment of cancer. It causes primarily intrastrand DNA-DNA cross-links, and is highly mutagenic and carcinogenic in both in vitro and in vivo experimental models. There is, however, considerable variability between the response seen in different cellular systems, probably at least partly because of the different cellular DNA...
