A method of the preparation of a nucleic acid binding compound is disclosed wherein a first protecting group removable by a medium strong base and a second protecting group removable by a medium strong acid are used. The synthesis is thereby is increased in recovery yield of a nucleic acid binding compound prepared.

Seven PNA-encoded combinatorial libraries targeting proteases and phosphatases with covalent reversible and irreversible mechanism-based inhibitors were prepared. The libraries were synthesized using modified PNA monomers, which dramatically increase the water solubility of the libraries in biologically relevant buffers. The libraries were shown to selectively inhibit targeted enzymes. (c) 2007 Elsevier Ltd. All rights reserved.
Expanding the Scope and Orthogonality of PNA Synthesis
nucleic acids (PNAs) hybridize to natural oligonucleotides according to Watson and Crick base-pairing rules. The robustness of PNA oligomers and ease of synthesis have made them an attractive platform to encode small or macromolecules for microarraying purposes and other applications based on programmable self assembly. A cornerstone of these endeavors is the orthogonality of PNAsynthesis with other chemistries

[reaction: see text] A practical and efficient method for PNAsynthesis using an azide group to mask the N-terminus is reported. The deprotection was carried out in 5 min, while couplings were complete within 60 min. The near neutral conditions of the phosphine deprotection combined with the base-free coupling using hydroxybenzotriazole-activated monomers make this approach very mild.
