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. And the article was included in Journal of Clinical Investigation on February 28,1995.Formula: C10H13FN2O5 The following contents are mentioned in the article:

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 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.

Eighty-seven pyrimidine base and nucleoside analogs were evaluated as inhibitors of uridine phosphorylase (UrdPase) [289-95-2] and thymidine phosphorylase (dThdPase) [9030-23-3]. These findings, together with an extensive literature review, have allowed construction of structure-activity relationships for the binding of ligands to UrdPase and dThdPase and provide a basis for the rational design of new inhibitors of these enzymes.

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.

Activities of 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-iodocytosine and its metabolites against herpes simplex virus types 1 and 2 in cell culture and in mice infected intracerebrally with herpes simplex virus type 2 was written by Schinazi, Raymond F.; Fox, Jack J.; Watanabe, Kyoichi A.; Nahmias, Andre J.. And the article was included in Antimicrobial Agents and Chemotherapy on January 31,1986.Electric Literature of C10H13FN2O5 The following contents are mentioned in the article:

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.

Human respiratory syncytial virus (RSV) is a neg.-sense RNA virus and a significant cause of respiratory infection in infants and the elderly. No effective vaccines or antiviral therapies are available for the treatment of RSV. ALS-8176 is a first-in-class nucleoside prodrug inhibitor of RSV replication currently under clin. evaluation. ALS-8112, the parent mol. of ALS-8176, undergoes intracellular phosphorylation, yielding the active 5′-triphosphate metabolite. The host kinases responsible for this conversion are not known. Therefore, elucidation of the ALS-8112 activation pathway is key to further understanding its conversion mechanism, particularly given its potent antiviral effects. Here, we have identified the activation pathway of ALS-8112 and show it is unlike other antiviral cytidine analogs. The first step, driven by deoxycytidine kinase (dCK), is highly efficient, while the second step limits the formation of the active 5′-triphosphate species. ALS-8112 is a 2′- and 4′-modified nucleoside analog, prompting us to investigate dCK recognition of other 2′- and 4′-modified nucleosides. Our biochem. approach along with computational modeling contributes to an enhanced structure-activity profile for dCK. These results highlight an exciting potential to optimize nucleoside analogs based on the second activation step and increased attention toward nucleoside diphosphate and triphosphate prodrugs in drug discovery.
