delivery, in vivo half-life, and pharmacokinetics. From this perspective, amides as neutral and hydrophobic internucleoside linkages in RNA are highly interesting modifications that so far have not been tested in RNA interference. Amides are remarkably good mimics of the phosphodiester backbone of RNA and can be prepared using a relatively straightforward peptide coupling chemistry. The synthetic challenge
