    摘要: Functionalized nucleomonomers and oligonucleotides are provided which have increased nuclease resistance and enhanced binding affinity to target DNA or RNA molecules. The oligonucleotides of the present invention comprise at least one 7-deaza-7-iodo-2'-substituted purine, herein referred to as a functionalized nucleomonomer. A preferred 2' substituent on the sugar moiety is a 2'-O-alkoxy alkyl group. More preferably, the 2'-substituent is 2'--O--CH.sub.2 --CH.sub.2 --O--CH.sub.3 (or 2'-methoxyethoxy). Such oligonucleotides are useful as therapeutics for modulating protein expression in organisms and treating disease states susceptible to oligonucleotide therapeutics. Such oligonucleotides are also useful as diagnostics for the diagnosis and detection of disease states, and as research reagents.

    摘要: New sub-monomer synthetic methods for the preparation of peptide nucleic acid oligomeric structures are disclosed that provide for the synthesis of both predefined sequence peptide nucleic acid oligomers as well as random sequence peptide nucleic acid oligomers. Further these methods also provide for the incorporation of peptide nucleic acid units or strings of such units with amino acids or strings of amino acids in chimeric peptide nucleic acid-amino acid compounds. Further disclosed are methods of making random libraries of peptide nucleic acids using the fully preformed monomers.
