Chiral peptide nucleic acid monomers (PNAM) with modified backbones.
Convenient high yielding syntheses of optically pure PNAMs comprising l- or d-serine, l-lysine and l-arginine units linked to thymine or Cbz-cytosine are described. Simple workup and inexpensive reagents are employed and free amino acids are used as coupling components.
متن کاملMicrobial production of poly-γ-glutamic acid.
Poly-γ-glutamic acid (γ-PGA) is a natural, biodegradable and water-soluble biopolymer of glutamic acid. This review is focused on nonrecombinant microbial production of γ-PGA via fermentation processes. In view of its commercial importance, the emphasis is on L-glutamic acid independent producers (i.e. microorganisms that do not require feeding with the relatively expensive amino acid L-glutami...
متن کاملPeptide nucleic acid microarrays.
A fast and economical procedure for the production of peptide nucleic acid (PNA) microarrays is presented. PNA oligomers are synthesized in a fully automatic manner in 96-well plates using standard Fmoc chemistry. Subsequently, the oligomers are released from the support and spotted onto glass or silicone slides, which were activated by succinimidyl ester. This process allows for a concomitant ...
متن کاملSynthesis of Neomycin-DNA/ Peptide Nucleic Acid Conjugates
Aminoglycoside antibiotics (Figs. 1 and 2), containing a unique polyamine/ carbohydrate structure, have attracted considerable attention because of their specific interactions with RNA. Their antibacterial activity is mainly exerted by their binding to the RNA of the bacterial ribosome, and thus interfering with the mRNA translation process. The miscoding causes membrane damage, which eventuall...
متن کاملNucleic Acid Synthesis
INTRODUCTION Synthesis in the field of nucleic acids has been a major and continuing interest in my laboratory ever since we knew the structures of the nucleic acids. Clearly the foundations of synthetic work in the nucleotide field were laid by the prolonged and intensive efforts of Professor Todd's laboratory (Cambridge, England) and it was my good fortune to be associated with this laborator...
