[EN] AMINOGLYCOSIDES AND USES THEREOF IN TREATING GENETIC DISORDERS [FR] AMINOGLYCOSIDES ET LEURS UTILISATIONS DANS LE TRAITEMENT DES TROUBLES GÉNÉTIQUES
New derivatives of aminoglycosides with a sidechain 1,2-aminoalcohol at the 5” position of ring III were designed, synthesized, and biologically evaluated. The novel lead structure (compound 6), exhibiting substantially enhanced selectivity toward eukaryotic versus prokaryotic ribosome, high readthrough activity, and considerably lower toxicity than the previous lead compounds, was discovered.

catalytic site-selective installation of a photoredox active carboxylic ester group to a specific hydroxyl unit of an unprotected sugar. The second step, namely, “editing”, features a C–O bondcleavage to form a carbon radical intermediate that undergoes further transformations such as C–H and C–C bond formations. Our strategy constitutes the most effective and shortest route in direct transformation and modification

GraphicsA wide variety of p-tolyl thioriboside donors are examined for O-ribosylations of primary and secondary alcohols. p-Tolylsulfenyl trifluoromethanesulfonate (p-TolSOTf) is very effective in promoting O-ribosylations with p-tolyl thioriboside; all reactions are completed within 1-15 min to provide the desired products in good yield with reliable alpha/beta selectivity. A wide range of functional groups are tolerated under these conditions. The described O-ribosylation conditions are very useful for the generation of ribosaminouridine library molecules in solution or on polymer support.
