Three liquid-phase processes for the elaboration of short orthogonally protected PNA have been devised. Two of these methods are similar to the convergent and divergent approaches in peptide synthesis. The third process consists in building a fully protected polyamide backbone, by using as many different and orthogonal protecting groups as there are different types of nucleic bases in the targeted polyPNA. Simultaneous and selective cleavage of one kind of protecting group allows the simultaneous attachment of several identical nucleobase units. (C) 1999 Elsevier Science Ltd. All rights reserved.

A cyclic molecule including a hexameric PNA sequence has been designed and synthesized in order to target the TARRNA loop of HIV-1 through the formation of a "kissing complex". For comparison, its linear analogue has also been investigated. The synthesis of the cyclic and linear PNA has been accomplished following a liquid-phase strategy using mixed PNA and fully N-protected (aminoethylglycinamide)
