Purine 2'-deoxy-2'-fluororibosides as antiinfluenza virus agents
J Med Chem 1993 Jan 8;36(1):119-25.PMID:8421277DOI:10.1021/jm00053a015.
Twenty purine 2'-deoxy-2'-fluororibosides were synthesized by enzymic pentosyl transfer from 2'-Deoxy-2'-fluorouridine. Each nucleoside analogue was assayed for cytotoxicity in uninfected Madin-Darby canine kidney cells and for their ability to suppress influenza A virus infections in these cells. The most potent antivirial activity was observed with analogues having an amino group in the 2-position of the purine moiety. All 2-unsubstituted analogues were less potent than their 2-amino counterparts. Furthermore, 2-methyl,2-methoxy, or 2-fluoro substitution obliterated antivirial activity. The most cytotoxic member of the series was the 2-fluoro-6-amino analogue (IC50 = 120 microM). 2'-Deoxy-2'-fluoroguanosine and those congeners readily converted to it by adenosine deaminase showed the most potent antivirial activity (IC50 = 15-23 microM). Little cytotoxicity was observed with this subgroup of analogues which renders them worthy of further investigation as potential antiinfluenza agents.
4'-C-Methoxy-2'-deoxy-2'-fluoro Modified Ribonucleotides Improve Metabolic Stability and Elicit Efficient RNAi-Mediated Gene Silencing
J Am Chem Soc 2017 Oct 18;139(41):14542-14555.PMID:28937776DOI:10.1021/jacs.7b07582.
We designed novel 4'-modified 2'-Deoxy-2'-fluorouridine (2'-F U) analogues with the aim to improve nuclease resistance and potency of therapeutic siRNAs by introducing 4'-C-methoxy (4'-OMe) as the alpha (C4'α) or beta (C4'β) epimers. The C4'α epimer was synthesized by a stereoselective route in six steps; however, both α and β epimers could be obtained by a nonstereoselective approach starting from 2'-F U. 1H NMR analysis and computational investigation of the α-epimer revealed that the 4'-OMe imparts a conformational bias toward the North-East sugar pucker, due to intramolecular hydrogen bonding and hyperconjugation effects. The α-epimer generally conceded similar thermal stability as unmodified nucleotides, whereas the β-epimer led to significant destabilization. Both 4'-OMe epimers conferred increased nuclease resistance, which can be explained by the close proximity between 4'-OMe substituent and the vicinal 5'- and 3'-phosphate group, as seen in the X-ray crystal structure of modified RNA. siRNAs containing several C4'α-epimer monomers in the sense or antisense strands triggered RNAi-mediated gene silencing with efficiencies comparable to that of 2'-F U.
The use of oligonucleotide probes containing 2'-deoxy-2'-fluoronucleosides for regiospecific cleavage of RNA by RNase H from Escherichia coli
Biochim Biophys Acta 1992 Feb 28;1130(1):41-6.PMID:1371935DOI:10.1016/0167-4781(92)90459-d.
Protected 2'-Deoxy-2'-fluorouridine and 2'-deoxy-2'-fluorocytidine suitable for incorporation into oligonucleotides via the phosphoramidite approach have been prepared. Five modified and two unmodified oligonucleotides have been synthesized to investigate the regiospecific cleavage of a 5S RNA from Escherichia coli by RNase H. In order to show whether the modified oligonucleotides are able to hybridize with the RNA the physico-chemical properties (melting curves, CD spectra) of analogous DNA/oligodeoxyribonucleotide duplexes have been examined. The modified oligonucleotides are shown to form stable duplexes with a DNA-matrix which exist in an A-like form. Two of the modified probes containing four 2'-deoxy-2'-fluorocytidines or two 2'-deoxy-2'-fluorouridines direct the splitting by RNase H of only one phosphodiester bond of the RNA.
Transcription of 2'-deoxy-2'-fluoro-modified and phosphorothioate-modified RNA templates by HIV-1 reverse transcriptase
Anticancer Res 1999 Nov-Dec;19(6B):5419-21.PMID:10697571doi
RNA templates yield the corresponding DNA in the presence of human immunodeficiency virus reverse transcriptase (HIV-1 RT). The purpose of this study was to determine whether RNA that was modified with either 2'-deoxy-2'-fluoro analogs or with internucleotide phosphorothioate linkages could serve as templates for HIV-1 RT. Modified RNA that contained either 2'-deoxy 2'-fluoro pyrimidine nucleoside analogs or internucleotide phosphorothioate diester linkages 5'- to pyrimidine nucleosides were enzymatically synthesized and tested for template activity with recombinant HIV-1 RT. RNA that was modified with either 2'-Deoxy-2'-fluorouridine or with internucleotide phosphorothioate linkages 5'- to pyrimidines yielded full length HIV-1 reverse transcription products, with complete fidelity in transcription. RNA that was modified with 2'-deoxy-2'-fluorocytidine, either alone or in combination with 2'-Deoxy-2'-fluorouridine, did not function as templates for HIV-1 RT, under the conditions reported here. The ability of 2'-deoxy-2'-fluoro-modified and phosphorothioate-modified RNA to serve as template for the RNA-dependent DNA polymerase of HIV-1 RT has not hitherto been reported.
Synthesis of oligonucleotide probes containing 2'-deoxy-2'-fluoronucleosides for cleavage of RNA by RNase H
Biomed Biochim Acta 1990;49(4):161-6.PMID:1698357doi
Modified oligodeoxyribonucleotides containing 3'-terminal 2'-Deoxy-2'-fluorouridine (UF) or 2'-fluorothymidine (TF) were successfully applied for specific RNA hydrolysis by RNase H from E. coli. The nonanucleotides d(CACCGCGCTF) and d(CACCGCGCUF) were synthesized using the phosphoramidite solid support method. The modified nucleosides were immobilized on the CPG support and provided the starting nucleoside residues. Model experiments were carried out using the 5S RNA from E. coli ribosomes and its 1-41 fragment. It was found that the use of this type of modified probes did not decrease neither the efficiency nor the specificity of the RNase H reaction.
