Targeting RNAs using small molecules is an emerging field of medicinal chemistry and holds promise for the discovery of efficient tools for chemical biology. MicroRNAs are particularly interesting targets since they are involved in a number of pathologies such as cancers. Indeed, overexpressed microRNAs in cancer are oncogenic and various series of inhibitors of microRNAsbiogenesis have been developed

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

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.

synthesis of new small-molecule RNA ligands with the aim of inhibiting Dicer-mediated processing of oncogenic miRNAs. One of the synthesized compound (4b) composed of the aminoglycoside neomycin conjugated to an artificial nucleobase and to amino acid histidine is able to selectively decrease miR-372 levels in gastric adenocarcinoma (AGS) cells and to restore the expression of the target LATS2 protein
