    • The use of this target-observation strategy (as opposed to ligand-observation schemes, such as saturation transfer) is essential to filter out promiscuous binders, which interact through nonspecific electrostatic interactions with the highly charged nucleic acid. Promiscuous binders cause a general broadening of the NMR spectrum of the target, whereas specific binders induce only peak shifts, which allow the identification of the binding site. For a general review, see: H. O. Villar, J. Yan, M. R. Hansen, Curr. Opin. Chem. Biol. 2004, 8, 387-391.

    • Lys3 ligands. However, they are too complex for a fragment-based approach. In contrast, compound 1 is an excellent 2-deoxystreptamine surrogate in the design of RNA-friendly compounds: L.

    • Both enantiomerically enriched (e.r, 93/7) isomers of compound 17 f were prepared. The dissociation constant Kd, 1.2 ± 0.6) μM was found for (R)-17 f with tRNA Lys3 at an ionic strength of 150 mM KCl, and K d, 1.1±0.7) μM was found for (S)-17 f under the same conditions. Thus, the interaction with tRNALys3 is not stereospecific, and racemic ligands can be used in this approach. For the enantioselective preparation of 1, see: a) A. Pérez Luna, M.-A. Ceschi, M. Bonin, L. Micouin, H.-P. Husson, S. Gougeon, G. Estenne Bouthou, B. Marabout, M. Sevrin, P. George, J. Org. Chem. 2002, 67, 3522-3524;
