Inhibition of hepatitis B virus by a novel L-nucleoside, 2′-fluoro-5-methyl-β-L-arabinofuranosyl uracil was written by Pai, S. Balakrishna; Liu, Shwu-Huey; Zhu, Yong-Lian; Chu, Chung K.; Cheng, Yung-Chi.

2′-Fluoro-5-methyl-β-L-arabinofuranosyl uracil (L-FMAU) was discovered to have potent antiviral activity against hepatitis B virus (HBV). L-FMAU was more potent than its D-enantiomer and produced dose-dependent inhibition of the viral DNA replication in 2.2.15 cells (human HepG2 cells with the HBV genome), with a 50% inhibitory concentration of 0.1 μμ. There was no inhibitory effect on HBV transcription or protein synthesis. In the 2.2.15 cell system, L-FMAU did not show any toxicity ≤200 μM, whereas the D-enantiomer was toxic, with a 50% inhibitory concentration of 50 μM. Repeated treatments of HepG2 cells with L-FMAU at a 1 μM concentration for 9 days did not result in any decrease in the total mitochondrial DNA content, suggesting that a mode of toxicity similar to that produced by 2′,3′-dideoxycytidine is unlikely. Also at concentrations as high as 200 μM, L-FMAU did not adversely affect mitochondrial function as determined by lactic acid production by L-FMAU-treated hepatoma cells. L-FMAU was metabolized in the cells to its mono-, di-, and triphosphates. A dose-dependent inhibition of HBV DNA synthesis by L-FMAU triphosphate was observed in the DNA polymerase assays with isolated HBV particles, suggesting that the mode of action of this compound could involve viral polymerase. However, L-FMAU was not incorporated into the cellular DNA. Considering the potent inhibition of the viral DNA synthesis and the non-toxicity of L-FMAU towards the host DNA synthetic machinery, this compound should be further explored for development as an anti-HBV drug. 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: 69256-17-3Quality Control of 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione).

Sensitivity of arabinosyladenine-resistant mutants of herpes simplex virus to other antiviral drugs and mapping of drug hypersensitivity mutations to the DNA polymerase locus was written by Coen, Donald M.; Fleming, H. Edward Jr.; Leslie, Laurel K.; Retondo, Margaret J.. And the article was included in Journal of Virology on February 28,1985.Electric Literature of C10H13FN2O5 The following contents are mentioned in the article:

Seven herpes simplex virus mutants which have been previously shown to be resistant to arabinosyladenine  [5536-17-4] were examined for their sensitivities to 4 types of antiviral drugs. These drugs were a pyrophosphate analog, 4 nucleoside analogs altered in their sugar moieties, 2 nucleoside analogs altered in their base moieties, and 1 altered in both. The 7 mutants exhibited 5 distinct phenotypes based on their sensitivities to the drugs relative to wild-type strain KOS. All mutants exhibited resistance to acyclovir  [59277-89-3] and arabinosylthymine  [605-23-2], as well as marginal resistance to iododeoxyuridine  [54-42-2], whereas all but one exhibited resistance to phosphonoformic acid  [4428-95-9]. The mutants exhibited either sensitivity or hypersensitivity to the other drugs tested, 2′-nor-deoxyguanosine  [82410-32-0], 5-methyl-2′-fluoroarauracil  [69256-17-3], 5-iodo-2′-fluoroarauracil  [69123-98-4], and bromovinyldeoxyuridine  [82768-44-3], some of which differed only slightly from drugs to which the mutants were resistant. These results suggest ways to detect and treat arabinosyladenine-resistant isolates in the clinic. Antiviral hypersensitivity was a common phenotype. Mutations conferring hypersensitivity to 2′-nor-deoxyguanosine in mutant PAAr5 and to bromovinyldeoxyridine in mutant tsD9 were mapped to nonoverlapping regions of 1.1 and 0.8 kilobase pairs, resp., within the herpes simplex virus DNA polymerase  [9012-90-2] locus. Thus, viral DNA polymerase mediates sensitivity to these 2 drugs. However, reports of mutations in the DNA polymerase locus conferring resistance to these 2 drugs could not be confirmed. All of the mutants exhibited altered sensitivity to ≥2 types of drugs, suggesting that single mutations affect recognition of the base, sugar, and triphosphate moieties of nucleoside triphosphates by viral polymerase. 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: 69256-17-3Electric Literature of C10H13FN2O5).

The treatment of woodchuck hepatitis virus infections with 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-iodocytosine and 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-methyluracil given i.p. caused complete and permanent decrease of serum virus endogenous DNA polymerase and viral DNA in all treated woodchucks but was associated with severe toxicity. By contrast, 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-ethyluracil (FEAU) induced a sustained, although less dramatic, decrease of viral replication without apparent toxic effect. FEAU was also effective when given orally, but in both cases the inhibitory effect was transient.

2′-Fluoro-5-methylarauracil (FMAU) (50 mg/kg, i.p. daily for 3 days) starting 1 day post-vaginal inoculation of herpes simplex virus-2 (HSV-2) in guinea pigs almost completely inhibited the appearance of primary genital lesions (GL) but did not reduce the establishment of HSV latency. When cyclophosphamide (Cy) (50 mg/kg, i.p. daily for 7 days) was simultaneously given, mild delayed GL were occasionally noticed in FMAU-treated animals. During HSV-2 latent infection, i.p. Cy 50 mg/kg, for 10 d could induce genital herpes recurrence in FMAU-treated animals. Cy, 300 mg/kg 3 times at weekly intervals could increase the incidence of recurrent GL, suggesting that the reactivation of latent HSV by Cy was dosage related.

Deglycosylation of antiherpesviral 5-substituted arabinosyluracil derivatives by rat liver extract and enterobacteria cells was written by Machida, Haruhiko; Watanabe, Yohko; Kano, Fumitaka; Sakata, Shinji; Kumagai, Masao; Yamaguchi, Toyofumi. And the article was included in Biochemical Pharmacology on March 15,1995.COA of Formula: C10H13FN2O5 The following contents are mentioned in the article:

A number of antiherpesviral 5-substituted derivatives of 1-β-D-arabinofuranosyluracil (araU) were significantly resistant to phosphorolysis by rat liver extract (S-9), but were gradually deglycosylated in a 2% enterobacteria cell suspension. The relative order of the resistance conferred by the different C-5 substituents was: 5-propynyl > 5-(E)-2-bromovinyl > 5-(E)-2-chlorovinyl > 5-Me > 5-iodo. The 2′-fluoro derivatives of araU were completely resistant to phosphorolysis by both liver extract and enterobacteria, whereas the corresponding ribofuranosyl and 2′-deoxyribofuranosyl nucleosides were easily phosphorolyzed by S-9, and were immediately cleaved in a 1% enterobacteria cell suspension. These findings suggest that antiherpesviral 5-substituted araU analogs can be relatively stable in vivo, when injected i.v., and that degradation of 1-β-D-arabinofuranosyl-5-(E-2-bromovinyl)uracil (sorivudine) following oral administration is due primarily to the action of enterobacteria. 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: 69256-17-3COA of Formula: C10H13FN2O5).

Differential mechanism of the cytostatic effect of (E)-5-(2-bromovinyl)-2′-deoxyuridine, 9-(1,3-dihydroxy-2-propoxymethyl)guanine, and other antiherpetic drugs on tumor cells transfected by the thymidine kinase gene of herpes simplex virus type 1 or type 2 was written by Balzarini, Jan; Bohman, Christina; De Clercq, Erik. And the article was included in Journal of Biological Chemistry on March 25,1993.Name: 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione The following contents are mentioned in the article:

After they have been transfected with the herpes simplex virus type 1 (HSV-1) or type 2 (HSV-2) thymidine kinase (TK) gene murine mammary carcinoma (FM3A) cells become highly sensitive to the growth inhibitory properties of the antiherpetic agents (E)-5-(2-bromovinyl)-2′-deoxyuridine (BVDU), 9-[(2-hydroxyethoxy)methyl]guanine (acyclovir, ACV), 9-[(1,3-dihydroxy-2-propoxy)methyl]guanine (DHPG, ganciclovir), and 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-methyluracil (FMAU). BVDU was 100-fold more potent an inhibitor of HSV TK gene-transfected tumor cell growth (50% inhibitory concentration (IC50), 0.0020-0.0047 μM) than FMAU or DHPG (IC50, 0.051-0.277 μM) and 1000-fold more potent than ACV (IC50, 0.42-4.9 μM). As a rule, the test compounds were more cytostatic to HSV-2 TK than HSV-1 TK gene-transfected FM3A cells. This may be ascribed to the higher phosphorylating capacity (Vmax/Km) of HSV-2 TK than HSV-1 TK and/or to the higher TK enzyme levels of the HSV-2 TK gene-transfected FM3A cells than the HSV-1 TK gene-transfected FM3A cells. Thymidylate synthase of the HSV TK gene-transfected FM3A cells appears to be the target enzyme for the cytostatic action of BVDU, but not FMAU, DHPG, or ACV. Instead, the cytostatic activity of DHPG seems to be correlated with its conversion to the triphosphate form and subsequent incorporation into the DNA of HSV TK gene-transfected FM3A cells.

The reaction kinetics and specificity of human and canine liver cytidine deaminase (I) for the virucide 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-iodocytosine (FIAC) and some other 5-substituted arabinofuranosylcytosine analogs are reported. The Km and Vmax values of human and canine I for FIAC differed significantly; marked kinetic differences of human and canine I were also observed with cytidine, deoxycytidine, arabinofuranosylcytidine, and deoxyfluoroarabinofuranosylcytosine. Studies with human I showed that substitution at the 5-position affected enzyme activity. Thus, although deoxyfluoroarabinofuranosylethylcytosine is a potent antiviral compound in vitro, it was not deaminated by human I.

Structural requirements for the enzymic deamination of cytosine nucleosides was written by Kreis, W.; Watanabe, K. A.; Fox, J. J.. And the article was included in Helvetica Chimica Acta on April 19,1978.SDS of cas: 56632-83-8 The following contents are mentioned in the article:

Thirty-three 1-β-D-pentofuranosylcytosine nucleosides were examined as substrates of crude cytidine deaminase from mouse kidney. Modification of the aglycone moiety by substitution of a F atom at C(5) resulted in a several-fold increase in the deamination velocity relative to cytidine, whereas insertion of a Me group at C(5) decreased the deamination velocity. This decrease was even more pronounced when a Me group was substituted at C(6). Though xylosylcytosine and 3′-deoxy-3′-fluoroxylocytosine were not substrates for this deaminase, those xylofuranosylcytosines bearing good leaving groups (e.g., bromo, mesyloxy, or tosyloxy) at C(3′) were deaminated with substantial deamination velocities. This is probably due to a prior chem. reaction leading to arabino nucleosides bearing a free 3′-OH in a down configuration. A different situation was obtained with arabino nucleosides. Though 1-β-D-arabinofuranosylcytosine and 2′-deoxy-2′-fluoro-1-β-D-arabinofuranosylcytosine were substrates for this deaminase, substitution of bulky groups (e.g., chloro, bromo, or mesyloxy) at C(2′) substantially decreased the susceptibility to deamination. A hypothesis is offered to explain these differences between xylo- and arabino-cytosines. The presence of a free OH group at the 5′-position is not essential for enzymic deamination. 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: 56632-83-8SDS of cas: 56632-83-8).
