Oligonucleotides modified by clinically ineffective trans-diamminedichloridoplatinum(II) (transplatin) have been shown to be effective modulators of gene expression. This is so because in some nucleotide sequences the 1,3-GNG intrastrand adducts formed by transplatin in double-helical DNA readily rearrange into interstrand cross-links...
