specifically to a DNA sequence were potent topoisomerase IB inhibitors. The targeting was achieved through covalent linkage to a sequence-specificDNAligand, a triplex-forming oligonucleotide, and was necessary to position and keep the nucleobase analogue in the cleavage complex. In the absence of triplex formation, only a weak binding to the DNA and topoisomerase I-mediated DNAcleavage was observed.

biological evaluation of new small‐molecule drugs that targetoncogenic miRNAs production. In particular, we chose to target two miRNAs (i.e., miRNA‐372 and ‐373) implicated in various types of cancer, such as gastric cancer. Their precursors (pre‐miRNAs) are overexpressed in cancer cells and lead to mature miRNAs after cleavage of their stem‐loop structure by the enzyme Dicer in the cytoplasm. Some of
