The antiviral compounds 9-β-D-arabinofuranosyladenine (ara-A), 9-β-D-arabinofuranosyl-2-fluoroadenine (FAA), 9-β-D-arabinofuranosylhypoxanthine (ara-Hx), 9-β-D-arabinofuranosylguanine (ara-G), 1-β-D-arabinofuranosylthymine (ara-T), 1-β-D-arabinofuranosyl-2′-fluorocytosine (FAC), 1-β-D-arabinofuranosyl-2′-fluoro-5-iodocytosine (FIAC), and 1-β-D-arabinofuranosyl-2′-fluoro-5-methyluracil (FMAU) were compared to 1-β-D-arabinofuranosyl cytosine (ara-C) in their ability to inhibit UV light-induced DNA repair in log phase and confluent human diploid fibroblasts. Inhibition of the polymerization or ligation steps of DNA excision repair manifests itself in the form of DNA single-strand breaks which may be quantitated through velocity sedimentation anal. in alk. sucrose gradients. In UV-irradiated quiescent, confluent human fibroblast cultures, treatment with any of the aranucleosides leads to accumulation of single-strand breaks but the ED for this inhibition varies greatly. The order of their effectiveness in confluent cultures was ara-C and its derivatives >ara-A, FAA, ara-G, Ara-HX > ara-T. In rapidly cycling cells, on the other hand, sensitivity to repair inhibition was exhibited only in response to ara-C and FAC. If 2 mM hydroxyurea (HU) was administered with ara-A, FAA, or FMAU, however, DNA strand breaks were seen. HU also increased the efficiencies of ara-C and FAC. No strand breaks were observed in UV-irradiated log-phase cells treated with FIAC, ara-Hx, ara-G, or ara-T even in the presence of HU. The efficiencies of inhibition of unscheduled DNA synthesis (UDS) and semiconservative DNA synthesis by the aranucleosides is consistent with their relative efficiencies at producing strand breaks. The ability of the aranucleosides to inhibit DNA is discussed with respect to their hypothesized effects on DNA metabolic processes in eukaryotic 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: 69256-17-3Computed Properties of C10H13FN2O5).

The antitumor activity of 1-(2-deoxy-2-fluoro-4-thio-β-D-arabinofuranosyl)cytosine (thio-FAC) was evaluated. Thio-FAC inhibited the in vitro growth of various human cancer cell lines, particularly the growth of cell lines established from gastric and colorectal carcinomas, while its oxy-type congener 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)cytosine (FAC) showed little or no activity against such solid cancer cell lines. Thio-FAC showed remarkable antitumor effects against human tumors s.c. implanted in nude mice and was highly effective even by oral administration. Thio-FAC was less susceptible to deamination by cytidine deaminase than FAC and 2′-deoxy-2′,2′-difluorocytidine (gemcitabine) and therefore is a promising drug for cancer chemotherapy. 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: 56632-83-8Application of 56632-83-8).

A new pyrimidine nucleoside, 2′-fluoro-5-methyl-1-β-D-arabinofuranosyluracil (I) [69256-17-3] was active against mouse and human leukemic cells in culture and against mouse leukemias L1210, P388, and P815 in vivo. In contrast to other 1-β-D-arabinofuranosylcytosine (ara-C) [147-94-4] derivatives, I, when given either i.p. or orally, was highly active against lines of leukemias P815 and L1210 made resistant to ara-C. Against P815/ara-C and L1210/ara-C, it is more effective than is 5- azacytidine, a drug which has shown definite effectiveness in patients with acute leukemia resistant to ara-C. Thus, I may be useful in treatment of ara-C resistant leukemias.

Therapeutic activities of 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)-5-iodocytosine and -thymine alone and in combination with acyclovir and vidarabine in mice infected intracerebrally with herpes simplex virus was written by Schinazi, Raymond F.; Peters, Jeanne; Sokol, M. Kathleen; Nahmias, Andre J.. And the article was included in Antimicrobial Agents and Chemotherapy on July 31,1983.Electric Literature of C10H13FN2O5 The following contents are mentioned in the article:

The therapeutic effectiveness of 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)-5-iodocytosine (I) [69123-90-6] and 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)thymine (II) [69256-17-3] was compared with that of acyclovir  [59277-89-3] and vidarabine  [5536-17-4]. In mice inoculated intracerebrally with high 50% LDs of herpes simplex virus type 2, nontoxic i.p. or oral treatments with the 2 new fluorinated antiviral agents were highly effective in reducing mortality. The 2 drugs were also effective when treatment was begun as late as 48 h after virus inoculation. The relative order of potencies of the drugs when compared on a molar basis or in terms of therapeutic index was II â‰?I > vidarabine â‰?acyclovir. The new pyrimidine analogs were also found to lack immunosuppressive activity in mice. The combination of I and vidarabine was the most effective; significantly greater reduction in mortality was achieved with this combination than with either drug alone. Thirty minutes after i.p. treatment with the fluorinated analogs, the drugs (or their metabolites) were transported to the brains of virus-inoculated and normal mice at levels about 1/3rd to 2/3rds those in the blood. The levels of II in the blood or brain were consistently higher than those found with equivalent i.p. doses of I. 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).

A mammalian cell line designed to test the mutagenic activity of anti-herpes nucleosides was written by Pizer, Lewis I.; Mitchell, Dawn H.; Bentele, Beatrice; Betz, Joan L.. And the article was included in International Journal of Cancer on July 15,1987.Electric Literature of C10H13FN2O5 The following contents are mentioned in the article:

The herpes simplex virus (HSV) thymidine kinase (tk) gene was transfected into Chinese hamster ovary (CHO) 51-11 gly- cells to test its effect on the cytotoxic and mutagenic activity of anti-herpetic nucleoside analogs. Acyclovir (ACV) was somewhat more cytotoxic in the 51-D3 cell line that expresses the viral TK than in the 51-11 parent line. Growth in ACV did not increase over background mutations at the hprt locus. FIAC (2′-fluoro-5-iodo-aracytosine) was slightly cytotoxic to the parent 51-11 line and the tk-containing clone 51-D3. FMAU (2′-fluoro-5-methylarauracil) had pronounced cytotoxicity in both cell lines; the 50% survival points were 1.0 μM for 51-11 cells and 0.2 μM for 51-D3. The clone 51-D3 was more sensitive than 51-11 to low concentrations of FIAU (2′-fluoro-5-iodo-arauracil), and when treated with FIAU 51-D3 had a mutation frequency to glycine independence 5 times greater than that of 51-11 cells. With both cell lines, the mutation frequency at the hprt locus was detected after 51-D3 cells were grown with iododeoxyuridine. Trifluorothymidine was more toxic to 51-D3 than to 51-11 cells and increased the mutation frequency 2-fold. Cytosine-β-D-arabinofuranoside showed no differential cytotoxicity on the 2 cell lines and did not increase the mutation frequency at the hprt locus. 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).

Use of a standardized cell culture assay to assess activities of nucleoside analogs against hepatitis B virus replication was written by Korba, Brent E.; Gerin, John L.. And the article was included in Antiviral Research on July 1,1992.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:

A cell culture system for the evaluation of compounds which inhibit hepatitis B virus (HBV) replication (Korba and Milman, Antiviral Res. 15:217, 1991) has been developed into a standardized assay. Toxicity of test compounds was assessed by the uptake of neutral red dye under cell culture and treatment conditions which were identical to those used for the antiviral assays. A total of 667 sep. cultures of 2.2.15 cells were evaluated for this study. In 86 untreated cell cultures, representing 15 experiments over a 24-mo period, the levels of extracellular HBV virion DNA and intracellular HBV DNA forms were found to vary by less than 2.5-fold overall. Virion DNA in serum and intracellular viral DNA replication intermediates [RI] are the two most reliable and commonly followed markers of hepadnavirus replication in patients and exptl. animals. In these assays, levels of extracellular HBV virion DNA and intracellular HBV RI were well correlated in 2.2.15 cells. Less correlation was observed between the levels of HBV virion DNA and the 3.2-kb episomal HBV genomes present in the cells. A threshold level of 22-37 intracellular replicating HBV genomes appeared to be required before virions were detected in the culture medium. The activities of several 2′-substituted and 3′-substituted deoxynucleoside analogs against HBV replication were compared using this standardized assay. Dideoxycytosine [ddC] and dideoxyguanosine [ddG] were the most selective 2′,3′-dideoxynucleosides against HBV in 2.2.15 cells. Substitution of fluorine at the 2′ position abolished the antiviral activity of ddC, but enhanced the selective antiviral activities of dideoxythymidine and dideoxyuracil. Several 2′-fluorinated pyrimidine arabinosyl furanosides, reported to be potent (but toxic) inhibitors of hepadnaviruses in vivo demonstrated relatively low selective antiviral activities in 2.2.15 cells. The current data base allows for validation of any given set of test evaluations through statistical anal. of both the pos. and the neg. treatment controls present in each experiment; thus, relevant comparisons of the selectivity of anti-HBV activities for different compounds examined in future experiments can be made. 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: 69256-17-3Name: 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione).

Bovine herpes mammillitis virus or bovine herpesvirus type 2 (BHV-2) causes ulcerative lesions on the teats and udders of infected cows. The authors investigated several nucleoside and nucleotide analogs as potential BHV-2 inhibitors. These included acyclovir, ganciclovir, 5-iodo-2′-deoxyuridine (IUdR), 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl) derivatives of 5-iodocytosine (FIAC), 5-iodouracil (FIAU), and 5-methyluracil (FMAU), and various 3-hydroxyphosphonylmethoxypropyl (HPMP) and 2-phosphonylmethoxyethyl (PME) derivatives of adenine (A), guanine (G), 2,6-diaminopurine (DAP), and/or cytosine (C). Of these, FIAU and FMAU were the most potent in cell culture, inhibiting 50% of BHV-2 plaques at <0.05 μM. HPMPA and HPMPG were active at 0.3 μM; FIAC, IUdR, and HPMPC at 1.3-2.3 μM; PMEDAP and ganciclovir at 20-25 μM; acyclovir and PMEA at >100 μM. The two most potent agents, FIAU and FMAU, inhibited uninfected embryonic bovine tracheal cell growth by 50% at >100 μM and 53 μM, resp., resulting in selectivity indexes (ratio of the 50% inhibitory concentration for cell growth to the 50% inhibitory concentration for plaque formation) of >2200 and 1100. Greater degrees of antiviral activity and selectivity were obtained in infected guinea pig embryo cells treated with FIAU, FMAU, and HPMPC. Infected cell extracts containing BHV-2-induced thymidine kinase activity phosphorylated FIAU, FMAU, and IUdR at nearly the same rate as thymidine, whereas FIAC, acyclovir, and ganciclovir were phosphorylated at â‰?% the rate of thymidine. Phosphorylation by this enzyme is required to generate the antivirally active nucleoside triphosphate in infected cells. In guinea pigs infected intravaginally with BHV-2, FMAU treatments of 1, 3.2, and 10 mg kg-1 per day for 5 days starting 1 day after virus challenge reduced vaginal lesion scores and virus titers in a dose-dependent manner. FIAU (10 μM) was as effective as 1 μM FMAU by the same regimen. A single treatment with 10 μM HPMPC was as active as daily treatments with 3.2 mg FMAU kg-1. These results indicate the potential of using antiviral agents to treat bovine herpes mammillitis virus infections in cattle, and the application of guinea pigs to study BHV-2 disease. 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).

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: 69256-17-3Application In Synthesis of 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione).

1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione (cas: 69256-17-3) belongs to pyrimidine derivatives. The pyrimidine nitrogenous bases are derived from the organic compound pyrimidine through the addition of various functional groups. For example, the neurotoxin tetrodotoxin is a pyrimidine derivative. It is found in a number of species including the Japanese puffer fish, the blue-ringed octopus, and the orange-bellied newt. Tetrodotoxin prevents the transmission of nerve signals and can result in paralysis and death.Application In Synthesis of 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione
