Fmoc-Based Assembly of PNA Oligomers: Manual and Microwave-Assisted Automated Synthesis.

Exploration of PNA-peptide conjugates as potential antisense antibiotics necessitates a fast and efficient synthesis protocols for amounts that facilitate determination of structure-activity relationships and in vivo studies in animal infection models. Fmoc/Boc-protected PNA monomers are here used for assembly of oligomers by optimized protocols involving either a manual synthesis method at room temperature or automated microwave-assisted coupling of monomers on a peptide synthesizer.
