B virus infection of humans results in high morbidity and mortality in as many as 80% of identified cases. The main objective of this study was to conduct a comparative anal. of conventional and exptl. antiviral drug susceptibilities of B virus isolates from multiple macaque species and zoonotically infected humans. We used a plaque reduction assay to establish the effective inhibitory doses of acyclovir, ganciclovir, and vidarabine, as well as those of a group of exptl. nucleoside analogs with known anti-herpes simplex virus activity. Four of the exptl. drugs tested were 10- to 100-fold more potent inhibitors of B virus replication than conventional antiviral agents. Drug efficacies were similar for multiple B virus isolates tested, with variations within 2-fold of the median effective concentration (EC50) for each drug, and each EC50 was considerably lower than those for B virus thymidine kinase (TK) mutants. We observed no differences in the viral TK amino acid sequence between B virus isolates from rhesus monkeys and those from human zoonoses. Differences in the TK protein sequence between cynomolgus and pigtail macaque B virus isolates did not affect drug sensitivity except in the case of one compound Taken together, these data suggest that future B virus zoonoses will respond consistently to conventional antiviral treatment. Further, the considerably higher potency of FEAU (2′-fluoro-5-ethyl-Ara-U) than of conventional antiviral drugs argues for its compassionate use in advanced human B virus infections. 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: 69256-17-3Synthetic Route of C10H13FN2O5).

Gemcitabine, pyrrologemcitabine, and 2′-fluoro-2′-deoxycytidines: Synthesis, physical properties, and impact of sugar fluorination on silver ion mediated base pairing was written by Guo, Xiurong; Leonard, Peter; Ingale, Sachin A.; Seela, Frank. And the article was included in Chemistry – A European Journal in 2017.SDS of cas: 56632-83-8 The following contents are mentioned in the article:

The stability of silver-mediated “”dC-dC”” base pairs relies not only on the structure of the nucleobase, but is also sensitive to structural modification of the sugar moiety. 2′-Fluorinated 2′-deoxycytidines with fluorine atoms in the arabino (up) and ribo (down) configuration as well as with geminal fluorine substitution (anticancer drug gemcitabine) and the novel fluorescent phenylpyrrolo-gemcitabine (phPyrGem) have been synthesized. All the nucleosides display the recognition face of naturally occurring 2′-deoxycytidine. The nucleosides were converted into phosphoramidites and incorporated into 12-mer oligonucleotides by solid-phase synthesis. The addition of silver ions to DNA duplexes with a fluorine-modified “”dC-dC”” pair near the central position led to significant duplex stabilization. The increase in stability was higher for duplexes with fluorinated sugar residues than for those with an unchanged 2′-deoxyribose moiety. Similar observations were made for “”dC-dT”” pairs and to a minor extent for “”dC-dA”” pairs. The increase in silver ion mediated base-pair stability was reversed by annulation of a pyrrole ring to the cytosine moiety, as shown for 2′-fluorinated phPyrGem in comparison with phenylpyrrolo-dC (phPyrdC). This phenomenon results from stereoelectronic effects induced by fluoro substitution, which are transmitted from the sugar moiety to the silver ion mediated base pairs. The extent of the effect depends on the number of fluorine substituents, their configuration, and the structure of the nucleobase. 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).

Four nucleoside analogs, 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-methyluracil (I), -5-iodouracil (II), -5-methylcytosine (III) and -5-iodocytosine (IV), were studied for their effect on human cytomegalovirus (HCMV) replication in vitro. I, II, III, and IV showed antiviral activities for 4 strains of HCMV (Major, Clegg, D550 and Towne) in a plaque reduction assay, with ED50s in the range of 0.1-0.65 μM. At 1 μM I or IV, the synthesis of 5 virus-specific late polypeptides was entirely blocked. Quantification of Towne viral DNA synthesis, using complementary RNA-DNA hybridization with a Towne-specific cRNA probe, demonstrated a complete inhibition of HCMV DNA replication at 1 μM I or IV. After the removal of the inhibitors, however, viral DNA synthesis resumed, and infectious virus reappeared, indicating that the inhibition of HCMV replication by these nucleoside analogs was of a virostatic reversible type. 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).

The 3 2′-fluoropyrimidine nucleosides 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-iodocytosine (FIAC) [69123-90-6], 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-iodouracil (FIAU) [69123-98-4], and 1-(2-deoxy-2-fluoro-β-D-arabinofuranosyl)-5-methyluracil (FMAU) [69256-17-3], showed high activity in RK13 monolayers against equine rhinopneumonitis virus, (EHV-1), Aujeszky’s disease virus (SHV-1, pseudorabies), and infectious bovine rhinotracheitis virus (1BR, BHV-1). The activity of these compounds was compared with 9-(1,3-dihydroxy-2-propoxymethyl)guanine (BW B759U, DHPG) in 2 laboratory animal disease models: EHV-1-induced hepatitis in hamsters and SHV-1-induced encephalitis in mice. All the compounds, provided from 3 to 5 h pre-infection for 5 days, were effective in preventing EHV-1 mortality (at 3-5 mg/kg per day) and in significantly reducing SHV-1 mortality (at 60 mg/kg per day). While FIAU had the greatest activity in vitro, FMAU tended to be more potent in vivo. The reasons for these differences between relative in vitro and in vivo activities are briefly discussed. 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: 69256-17-3Product Details of 69256-17-3).

Activity of 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-iodouracil against simian varicella virus infections in African green monkeys was written by Soike, Kenneth F.; Cantrell, Connie; Gerone, Peter J.. And the article was included in Antimicrobial Agents and Chemotherapy on January 31,1986.Category: pyrimidines The following contents are mentioned in the article:

The fluorinated pyrimidines 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-iodouracil (FIAU) [69123-98-4] and 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-methyluracil (FMAU) [69256-17-3] are highly effective inhibitors of herpesvirus infections in vitro and in vivo. This report is concerned with an evaluation of their activities in African green monkeys (Cercopithecus aethiops) infected with simian varicella virus, a herpesvirus closely related to human varicella-zoster virus. Oral or i.v. administration of FIAU at 50 mg/kg daily as divided doses beginning 48 h after virus inoculation prevented the development of evidences of clin. infection. Oral treatment with FIAU at 30 mg/kg daily deferred as late as 7 days after virus inoculation modified the course of the disease. When treatment was started 48 h after virus inoculation, daily doses of FIAU as small as 1 mg/kg inhibited development of infections; daily doses of 0.2 mg/kg were ineffective. At the latter dose, FMAU prevented development of clin. disease, suggesting that it was more active than FIAU. No signs of FIAU toxicity were observed, with the single exception of an early but transitory elevation in aspartate aminotransferase activity in serum. 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).

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.

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).

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 ring system has wide occurrence in nature as substituted and ring fused compounds and derivatives. A Cu-catalyzed and 4-HO-TEMPO-mediated [3 + 3] annulation of commercially available amidines with saturated ketones enables an efficient and facile synthesis of structurally important pyrimidines via a cascade reaction of oxidative dehydrogenation/annulation/oxidative aromatization.Electric Literature of C10H13FN2O5
