As measured by plaque and yield reduction assays, several metabolites of 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-iodocytosine (FIAC) were highly active against herpes simplex virus types 1 and 2. These metabolites included the 2′-deoxy-2′-fluoroarabinosyl derivatives of 5-iodouracil, cytosine, uracil, and thymine. In mice inoculated intracerebrally with herpes simplex virus type 2, the relative order of potency of these compounds and known antiviral drugs were as follows: 2′-fluoro-5-methylarabinosyluracil (FMAU) [69256-17-3] ≫ 2′-fluoro-5-iodoarabinosylcytosine (FIAC) [69123-90-6] ≈ 2′-fluoro-5-iodoarabinosyluracil (FIAU) [69123-98-4] > acyclovir ≈ vidarabine ≫ 2′-fluoroarabinosylcytosine (FAC) [56632-83-8] ≈ 2′-fluoroarabinosyluracil (FAU) [69123-94-0]. One of the main metabolites of FMAU, 2′-fluoro-5-hydroxymethylarabinosyluracil  [94817-51-3], was essentially inactive in vivo. FIAC-, FIAU-, FMAU-, FAC-, and FAU-resistant herpes simplex virus variants prepared in cell culture were found to be (i) devoid of viral thymidine kinase  [9002-06-6], (ii) cross-resistant to one another and resistant to drugs requiring viral thymidine kinase for activation, and (iii) sensitive to vidarabine or phosphonoformate. These results indicate that FIAC, FIAU, and FMAU require the virally encoded thymidine kinase for activation and suggest that the antiviral activity of FAU and FAC in cell cultures is also mediated by this enzyme. The interaction of the fluoroarabinosylpyrimidine nucleosides with herpes simplex virus thymidine kinase in a cell-free system is also described. 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: 56632-83-8Name: 4-Amino-1-((2R,3S,4R,5R)-3-fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)pyrimidin-2(1H)-one).

Fluorine configuration at C2′ of the bis(2′-fluorothymidine) dinucleotide is demonstrated to drive intramol. base stacking. 2′-β F-Configuration drastically reduces stacking compared to the 2′-α series. Hence, base stacking emerges as being tunable by the C2′-F stereoconfiguration through dramatic puckering variations scrutinized by NMR and natural bond orbital anal. Accordingly, 2′-β F-isomer photoreactivity is significantly reduced compared to that of the 2′-α F-isomer. 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 crystals of two new salts, 2,6-diamino-4-chloropyrimidin-1-ium 5-chlorosalicylate, C4H6ClN4+·C7H4ClO3-, (I), and bis(2,6-diamino-4-chloropyrimidin-1-ium) naphthalene-1,5-di-sulfonate, 2C4H6ClN4+·C10H6O6S22-, (II), have been synthesized and characterized by single-crystal X-ray diffraction. In both compounds, the N atom of the pyrimidine group in between the amino substituents is protonated and the pyrimidinium cation forms a pair of N-H···O hydrogen bonds with the carboxylate/sulfonate ion, leading to a robust R22(8) motif (supramol. heterosynthon). In compound (I), a self-complementary base pairing involving the other pyrimidinium ring nitrogen atom and one of the amino groups via a pair of N-H···N hydrogen bonds [R22(8) homosynthon] is also present. In compound (II), the crystallog. inversion center coincides with the inversion center of the naphthalene-1,5-disulfonate ion and all the sulfonate O atoms are hydrogen-bond acceptors, generating fused-ring motifs and a quadruple DDAA array. A halogen-bond (Cl···Cl) interaction is present in (I) with a distance and angle of 3.3505 (12) Å and 151.37 (10)°, resp. In addition, a C-Cl···π interaction and a π-π interaction in (I) and a π-π interaction in (II) further stabilize these crystal structures.

Cellular and molecular events leading to mitochondrial toxicity of 1-(2-deoxy-2-fluoro-1-β-D-arabinofuranosyl)-5-iodouracil in human liver cells was written by Cui, Lixin; Yoon, Sahyun; Schinazi, Raymond F.; Sommadossi, Jean-Pierre.

We have explored the mechanism(s) related to FIAU-induced liver toxicity, particularly focusing on its effect on mitochondrial function in a human hepatoma cell line-HepG2. The potential role of FMAU and FAU, metabolites detected in FIAU-treated patients were also ascertained; FIAU and FMAU inhibited cell growth and were effectively phosphorylated. A substantial increase in lactic acid production in medium of cells incubated with 1-10 μM FIAU or FMAU was consistent with mitochondrial dysfunction. Slot blot anal. demonstrated that a two week exposure to 10 μM FIAU or FMAU was not associated with a decrease in total mitochondrial (mt) DNA content. However, FIAU and FMAU were incorporated into nuclear and mtDNA and relative values suggest that both compounds incorporate at a much higher rate into mtDNA. Electron micrographs of cells incubated with 10 μM FIAU or FMAU revealed the presence of enlarged mitochondria with higher cristae d. and lipid vesicles. In conclusion, these data suggest that despite the lack of inhibition of mtDNA content, incorporation of FIAU and FMAU into mtDNA of HepG2 cells leads to marked mitochondrial dysfunction as evidenced by disturbance in cellular energy metabolism and detection of micro- and macrovesicular steatosis. 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: 69256-17-3Formula: C10H13FN2O5).

The bovine herpesvirus type 4 (BHV-4) group has a slow replication cycle, a narrow host range, and cytopathogenic effects characteristic of cytomegaloviruses (CMV), but a Group B genome structure similar to that of lymphotropic Herpesvirus saimiri (HVS). Reference BHV-4 strain DN599 and BHV-4 strains N124 and FHV-2 induced in the cytosol fraction of thymidine kinase-neg. (TK-) rabbit skin (RAB-BU) cell mutants a novel TK activity. The BHV-4-induced thymidine kinase (TK) differed from the principal cytosol TK of mock-infected cells in polyacrylamide gel electrophoresis mobility (Rm) under nondenaturing conditions and in the capacity to efficiently substitute CTP for a ATP as a phosphate donor. The BHV-4 thymidine phosphorylating activity was also distinguished from many common herpesvirus-induced TKs because it lacked iododeoxycytidine phosphorylating activity. Iododeoxyuridine, trifluorothymidine, and bromovinyldeoxyuridine inhibited [3H]thymidine (0.01 mM) phosphorylation by the BHV-4 enzyme in a dose-dependent manner, but arabinosylthymine and 2′-fluoro-5-methyl-arabinosyluracil (FMAU) were poor inhibitors of [3H]thymidine phosphorylation, and acyclovir and (dihydroxy-2-propoxymethyl)guanine (DHPG) did not inhibit at all at 60- and 40-fold the concentrations of [3H]thymidine, resp.

Phosphorylation of pyrimidine deoxynucleoside analog diphosphates: selective phosphorylation of L-nucleoside analog diphosphates by 3-phosphoglycerate kinase was written by Krishnan, Preethi; Fu, Qin; Lam, Wing; Liou, Jieh-Yuan; Dutschman, Ginger; Cheng, Yung-Chi. And the article was included in Journal of Biological Chemistry on February 15,2002.Safety of 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:

D-Nucleoside analogs, which are in the natural configuration, as well as the L-nucleoside analogs, are clin. relevant antiviral and anticancer agents. Metabolism of L-nucleoside analog diphosphates to the triphosphates, however, remains unexplored. Studies with recombinant nm23-H1 and -H2 isoforms indicated that L-nucleoside analog diphosphates were not phosphorylated by their nucleoside diphosphate kinase (NDPK) activity. Therefore, roles of creatine kinase, 3-phosphoglycerate kinase, and pyruvate kinase were evaluated using preparations from com. sources and human HepG2 cells. Phosphorylation of L-OddC, L-SddC, L-Fd4C, L-FMAU, and L-ddC were compared with D-deoxynucleoside analogs, Ara C, dFdC, and D-FMAU, and D-dideoxynucleoside analogs, ddC and d4T. Results based on preparations from HepG2 cells showed that L-nucleoside analog diphosphates were selectively phosphorylated by 3-phosphoglycerate kinase, whereas, D-deoxynucleoside analog diphosphates were phosphorylated by NDPK. Interestingly, ddCDP and d4TDP were substrates for creatine kinase, but were not phosphorylated by NDPK. In conclusion, it is proposed that specificity of the phosphorylating enzymes toward the nucleoside analog diphosphates is dependent on the configuration of the analog (L or D) and the presence or absence of 3′-hydroxyl group in the sugar moiety. The enzymic process of phosphorylation of L- and D-nucleoside analog diphosphates is different in cells. 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: 69256-17-3Safety of 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione).
