In order to find the effects of unnatural nucleosides on the stability of duplex, several oligonucleotides containing 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-uracil (FAU), -cytosine (FAC) and -thymine (FMAU) were synthesized by two alternative approaches: phosphoramidite method on an ABI 392 synthesizer and H-phosphonate procedure on the authors’ GeneSyn I universal module synthesizer. It was shown from the melting profiles that the presence of FMAU has a large stabilizing effect on the duplex. Replacement of thymidine with FAU, or deoxycytidine with FAC resulted in the formation of less stable duplexes. Temperature-dependent CD spectroscopy demonstrated that the structures of the fluorine containing oligomers are very similar to those of unmodified oligomers.

Puckering of the sugar unit in nucleosides and nucleotides is an important structural aspect that directly influences the helical structure of nucleic acids. The preference for specific puckering modes in nucleic acids can be analyzed via in silico conformational anal., but the large amount of conformations and the accuracy of the anal. leads to an extensive amount of computational time. In this paper, we show that the combination of geometry optimizations with the HF-3c method with single point energies at the RI-MP2 level results in accurate results for the puckering potential energy surface (PES) of DNA and RNA nucleosides while significantly reducing the necessary computational time. Applying this method to a series of known xeno nucleic acids (XNAs) allowed us to rapidly explore the puckering PES of each of the resp. nucleosides and to explore the puckering PES of six-membered modified XNA (HNA and β-homo-DNA) for the first time.

The antiviral compounds 9-β-D-arabinofuranosyladenine (ara-A), 9-β-D-arabinofuranosyl-2-fluoroadenine (FAA), 9-β-D-arabinofuranosylhypoxanthine (ara-Hx), 9-β-D-arabinofuranosylguanine (ara-G), 1-β-D-arabinofuranosylthymine (ara-T), 1-β-D-arabinofuranosyl-2′-fluorocytosine (FAC), 1-β-D-arabinofuranosyl-2′-fluoro-5-iodocytosine (FIAC), and 1-β-D-arabinofuranosyl-2′-fluoro-5-methyluracil (FMAU) were compared to 1-β-D-arabinofuranosyl cytosine (ara-C) in their ability to inhibit UV light-induced DNA repair in log phase and confluent human diploid fibroblasts. Inhibition of the polymerization or ligation steps of DNA excision repair manifests itself in the form of DNA single-strand breaks which may be quantitated through velocity sedimentation anal. in alk. sucrose gradients. In UV-irradiated quiescent, confluent human fibroblast cultures, treatment with any of the aranucleosides leads to accumulation of single-strand breaks but the ED for this inhibition varies greatly. The order of their effectiveness in confluent cultures was ara-C and its derivatives >ara-A, FAA, ara-G, Ara-HX > ara-T. In rapidly cycling cells, on the other hand, sensitivity to repair inhibition was exhibited only in response to ara-C and FAC. If 2 mM hydroxyurea (HU) was administered with ara-A, FAA, or FMAU, however, DNA strand breaks were seen. HU also increased the efficiencies of ara-C and FAC. No strand breaks were observed in UV-irradiated log-phase cells treated with FIAC, ara-Hx, ara-G, or ara-T even in the presence of HU. The efficiencies of inhibition of unscheduled DNA synthesis (UDS) and semiconservative DNA synthesis by the aranucleosides is consistent with their relative efficiencies at producing strand breaks. The ability of the aranucleosides to inhibit DNA is discussed with respect to their hypothesized effects on DNA metabolic processes in eukaryotic cells.

Hepatitis C virus afflicts approx. 180 million people worldwide and currently there are no direct acting antiviral agents available to treat this disease. Our first generation nucleoside HCV inhibitor, RG7128 has already established proof-of-concept in the clinic and is currently in phase IIb clin. trials. As part of our continuing efforts to discover novel anti-HCV agents, 3′,4′-oxetane cytidine and adenosine nucleosides were prepared as inhibitors of HCV RNA replication. These nucleosides were shown not to be inhibitors of HCV as determined in a whole cell subgenomic replicon assay. However, 2′-mono/diflouro analogs were readily phosphorylated to their monophosphate metabolites by deoxycytidine kinase and their triphosphate derivatives were shown to be inhibitors of HCV NS5B polymerase in vitro. Lack of anti-HCV activity in the replicon assay may be due to the inability of the monophosphates to be converted to their corresponding diphosphates.

CE coupled with UV detection was assessed as a possible platform for the chem. identity and purity anal. of positron emission tomog. (PET) tracers using [18F]FAC and [18F]FLT as examples. Representative samples containing mixtures of the tracers plus well-known impurities, as well as real radioactive samples (formulated for injection), were analyzed. Using MEKC with SDS in a neutral phosphate buffer, the separation of all compounds in the samples was achieved with baseline resolutions in less than 4.5 min and 3 min for FLT and FAC samples, resp. In comparison to the gold-standard for chem. anal. (i.e. HPLC/UV), we have demonstrated improvements in anal. times, and comparable LOD. Although the reproducibility in migration time is slightly lower than that of the HPLC, identification of the compounds was still possible due to good peak separation In addition, we show that CE can be used to identify and quantify Krytofix2.2.2 (a toxic and commonly used phase transfer catalyst) in less than 2 min and with a LOD of 45 μg/mL (non-optimized). These results demonstrate adequate performance for chem. identity and purity anal. Combined with the potential for miniaturization into a microchip format, these results suggest the potential of CE as an integral part of a miniaturized quality control system for PET tracers.

I-Motifs are four-stranded DNA structures consisting of two parallel DNA duplexes held together by hemi-protonated and intercalated cytosine base pairs (C:CH+). They have attracted considerable research interest for their potential role in gene regulation and their use as pH responsive switches and building blocks in macromol. assemblies. At neutral and basic pH values, the cytosine bases deprotonate and the structure unfolds into single strands. To avoid this limitation and expand the range of environmental conditions supporting i-motif folding, we replaced the sugar in DNA by 2-deoxy-2- fluoroarabinose. We demonstrate that such a modification significantly stabilizes i-motif formation over a wide pH range, including pH 7. NMR experiments reveal that 2-deoxy-2- fluoroarabinose adopts a C2′-endo conformation, instead of the C3′-endo conformation usually found in unmodified i-motifs. Nevertheless, this substitution does not alter the overall i-motif structure. This conformational change, together with the changes in charge distribution in the sugar caused by the electroneg. fluorine atoms, leads to a number of favorable sequential and inter-strand electrostatic interactions. The availability of folded i-motifs at neutral pH will aid investigations into the biol. function of i-motifs in vitro, and will expand i-motif applications in nanotechnol. This study involved multiple reactions and reactants, such as 4-Amino-1-((2R,3S,4R,5R)-3-fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)pyrimidin-2(1H)-one (cas: 56632-83-8Category: pyrimidines).
