However, the efficiency of nucleic acids is often hampered by inherent limitations in numerous practical applications, including limited access to complex functional patterns due to only four building blocks, facile degradation by nucleases, rapid renal clearance, poor pharmacokinetic ...
DNA G‐quadruplexes (GQs) are of great interest due to their involvement in crucial biological processes such as telomerase maintenance and gene expression. Furthermore, they are reported as catalytically active DNAzymes and building blocks in bio‐nanotechnology. GQs exhibit remar...

P5′ PHOSPHORAMIDATE BUILDING BLOCKS]]>doi:10.1081/NCN-200060068A new synthetic approach to 5′-phosphoramidites of 3′-aminonucleosides was developed. The methodology relies upon the use of 3′-amino-2′,3′-dideoxy nucleosides as the key starting materials. The final phosphoramidite products ...
Along with smooth oligomerization conditions, the syntheses of oxetane- and flavin-functionalized Fmoc-protected (2-aminoethyl)glycine building blocks are reported. (漏 Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)Thorsten
RNA tertiary structure motifs are stabilized by a wide variety of hydrogen-bonding interactions. Protonated A and C nucleotides are normally not considered to be suitable building blocks for such motifs since their pKa values are far from physiological pH. Here, we report the NMR solution structure...
