Human cytomegalovirus-induced DNA polymerase  [9012-90-2] and cellular DNA polymerase α were purified by successive chromatog. on DEAE-cellulose, phosphocellulose, heparin agarose, and single-stranded DNA agarose columns. The purified virus-induced DNA polymerase was resolved to 2 polypeptides corresponding to mol. weights of 140,000 and 58,000, as analyzed by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. Virus-induced DNA polymerase and cellular α polymerase were examined for their sensitivities to the triphosphates of 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-methyluracil (FMAUTP) [69256-17-3], -5-iodocytosine (FIACTP) [69123-90-6], and -5-methylcytosine (FMACTP) [78636-53-0]. The inhibitive effects of these triphosphates on the DNA polymerases were competitive with regard to the natural substrates; thus FMAUTP completes with dTTP  [365-08-2], and FIACTP and FMACTP complete with dCTP  [2056-98-6]. The inhibition constants (Ki) for FMAUTP, FIACTP, and FMACTP of virus-induced DNA polymerase are 0.06, 0.30, and 0.47 μM, resp. Cellular DNA polymerase α is much less sensitive to these inhibitors, and its Ki values for FMAUTP, FIACTP, and FMACTP are 0.45, 3.10, and 2.90 μM, resp. In addition, human cytomegalovirus-induced DNA polymerase, but not cellular DNA polymerase α, can utilize these analog triphosphates as alternate substrates for their corresponding natural deoxyribonucleoside triphosphates in in vitro DNA synthesis. This study involved multiple reactions and reactants, such as 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione (cas: 69256-17-3Computed Properties of C10H13FN2O5).

Equine herpes virus 1 and pseudorabies virus resistance to 2′-fluoropyrimidine analogs and to bromovinyldeoxyuridine: implications for dTMP kinase activity was written by Veerisetty, V.; Balasubramaniam, N. K.; Gentry, G. A.. And the article was included in Acta Virologica (English Edition) on December 31,1990.Category: pyrimidines The following contents are mentioned in the article:

The 2′-fluoropyrimidine nucleoside analogs 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-iodocytosine (FIAC), 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-methyluracil (FMAU), and 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-iodouracil (FIAU) showed higher in vitro activity against herpes simplex virus type 1 (HSV-1) than equine herpesvirus 1 (EHV-1) or pseudorabies virus (PRV). Comparison of the 50% plaque inhibitory doses for HSV-1 and its mutant MMdUr-20 in cell cultures with inhibition constants for the viral deoxythymidine kinases (dTKs) suggests that in the infected cell FMAU is phosphorylated by host enzymes. As compared to HSV-1, EHV-1 and PRV were more resistant to E-5-(2-bromovinyl)-2′-deoxyuridine (BVdU) and to the 2′-fluoropyrimidine analogs, as are HSV-2 and the HSV-1 mutants MMdUr-20 and S1. Because the dTKs of the latter lack deoxythymidylate kinase (dTMPK) activity, there appears to be a correlation between resistance to these analogs and BVdU on the one hand, and lack of dTMPK activity on the other. EHV-1 and PRV dTKs lack significant dTMPK activity. This study involved multiple reactions and reactants, such as 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione (cas: 69256-17-3Category: pyrimidines).

Alterations in the recognition of nucleoside analogs as substrates by the deoxythymidine kinase of a 5-methoxymethyldeoxyuridine-resistant mutant of herpes simplex virus type 1 was written by Veerisetty, V.; Veerisetty, Indira K.; Gentry, Glenn A.. And the article was included in Journal of General Virology on December 31,1983.HPLC of Formula: 69256-17-3 The following contents are mentioned in the article:

Inhibition constants (Kis) were used as an estimate of the ability of various nucleoside analogs to be recognized as substrates by the deoxythymidine kinases (dTKs) of a 5-methoxymethyldeoxyuridine-resistant (MMdUr) mutant of herpes simplex virus type 1 (HSV-1) and its parent wild-type (wt). The Kis for the 5-position analogs MMdU, [E]-5-(2-bromovinyl)deoxyuridine, bromodeoxyuridine, and iododeoxyuridine were increased approx. 3-5-fold, suggesting that they were poorer substrates for the MMdUr dTK than for the wt dTK. With the 2′ analogs arabinosylthymine and 2′-fluoro-5-methylarabinosyluracil, however, the Kis were increased to a much greater extent, 80- and 240-fold, resp. These findings suggest that the resistance of the mutant MMdUr to these analogs may be due to a mutation(s) in the viral dTK that directly affects binding at the 2′ recognition site and indirectly at the 5, while still allowing substantial activity with the natural substrate deoxythymidine. This study involved multiple reactions and reactants, such as 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione (cas: 69256-17-3HPLC of Formula: 69256-17-3).

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.

Ribonucleoside I (R = H, R1 = F) is less active against HSV-1 and HSV-2 than arabinonucleoside I [R = F, R1 = H (II)]. The relationship between mol. conformation and antiviral activity of I is discussed. The rotational energy caused probably by the 2′-“”up””-fluoro substituent in the sugar moiety might lock II in an anti conformation, which might account for the potent antiviral activity.

We examined the effects of 1-(2-deoxy -2-fluoro-β-D-arabinofuranosyl)-thymine (or FMAU, a potent antiviral nucleoside) on the stability of duplex and triplexes. When compared the stability of the self-complementary 5′-A5T5 duplex with 5′-A5X5 (X = FMAU), duplex containing FMAU has much higher melting temperature (Tm). 5-A6T5T3X3T5F3X3 and T3X3T5A6T5F3X3 form the parallel and antiparallel triplexes T3X3:A6:X3T3, resp. The former exhibited the typical T:A:T triplex behavior with only one melting temperature at 70 °C and 45 °C in 1.0 M and 0.2 M NaCl solution, resp., whereas the latter has two Tm values at 56 °C and 28 °C in 1.0 M solution FMAU clearly stabilize the triplex structure as A6T22 which forms the parallel triplex T6:A6:T6 has also only one Tm at 54 °C and 37 °C and 37 °C in high and low salt concentration solutions, resp. A 31mer 5′-TCCTCCTTTTTTAGGAGGATTTTTTGGTGGT and 5′-TCCTCCTTTTTTAGGAGGATTTTTTX’X’TX’X’T (X’ = 2′-deoxy-5-methylcytidine) were prepared to study their triplex forming potential. The former was found to have a weak interaction of the Watson-Crick duplex with the mismatched third-strand at all pH. The latter formed a stable triplex at lower pH consistent with required protonation on the 5-methylcytosine base.

The effects of mismatched double-stranded RNA (mdsRNA) and 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-methyl-uracil (D-FMAU) on the replication of duck hepatitis B virus (DHBV) were examined in duck primary hepatocytes infected with DHBV. The 50% inhibitory doses of m-dsRNA and D-FMAU for the replication of DHBV DNA were 0.34±0.06 and 0.007±0.001 μg mL-1, resp. Mismatched dsRNA slightly inhibited the intermediate DHBV DNA at a concentration as high as 1.0 μg mL-1, whereas the DHBV replicative form was markedly suppressed in the presence of 0.1 μg mL-1 of D-FMAU. On the other hand, m-dsRNA inhibited DHBV DNA replication even after the compound was removed from the culture medium, while the efficacy of D-FMAU did not persist after the cessation of treatment. The anal. of DHBV RNA revealed that m-dsRNA markedly inhibited DHBV RNA transcription, while D-FMAU only marginally suppressed the transcription of viral RNA. These results indicate that m-dsRNA inhibits DHBV RNA transcription rather than DHBV DNA replication and that this suppression of DHBV RNA transcription may produce persistent inhibition of DHBV replication.

2′-Fluoroarabinonucleic acid modification traps G-quadruplex and i-motif structures in human telomeric DNA was written by Abou Assi, Hala; El-Khoury, Roberto; Gonzalez, Carlos; Damha, Masad J.. And the article was included in Nucleic Acids Research on November 16,2017.Synthetic Route of C9H12FN3O4 The following contents are mentioned in the article:

Human telomeres and promoter regions of genes fulfill a significant role in cellular aging and cancer. These regions comprise of guanine and cytosine-rich repeats, which under certain conditions can fold into G-quadruplex (G4) and i-motif structures, resp. Herein, we use UV, CD and NMR spectroscopy to study several human telomeric sequences and demonstrate that G4/i-motif-duplex interconversion kinetics are slowed down dramatically by 2′-β-fluorination and the presence of G4/i-motif-duplex junctions. NMR-monitored kinetic experiments on 1:1 mixtures of native and modified Cand G-rich human telomeric sequences reveal that strand hybridization kinetics are controlled by G4 or i-motif unfolding. Furthermore, we provide NMR evidence for the formation of a hybrid complex containing G4 and i-motif structures proximal to a duplex DNA segment at neutral pH. While the presence of i-motif and G4 folds may be mutually exclusive in promoter genome sequences, our results suggest that they may co-exist transiently as intermediates in telomeric sequences.
