Inhibition of B virus (Macacine herpesvirus 1) by conventional and experimental antiviral compounds was written by Krug, P. W.; Schinazi, R. F.; Hilliard, J. K.. And the article was included in Antimicrobial Agents and Chemotherapy in 2009.Synthetic Route of C10H13FN2O5 The following contents are mentioned in the article:

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).

And the article was included in Journal of Pharmaceutical Sciences in 1975.Application In Synthesis of 2,6-Diamino-4-chloropyrimidine-1-oxide The following contents are mentioned in the article:

The biotransformation of minoxidil (I) [38304-91-5] was studied in the rat, dog, and monkey and compared to reported results in the human. Each species excreted substantially the same metabolites, but in quite different relative amounts The monkey and the human exhibited similar metabolite profiles, whereas the dog and rat were quant. different from each other and from the monkey and human. The major excretory product for the monkey and human was I glucuronide [56828-40-1]. Substantially smaller amounts of unchanged I, 2,4-diamino-6-(4′-hydroxypiperidino)pyrimidine 3-oxide [56828-37-6], and more polar metabolites also were excreted by these 2 species. The major excretory product in the rat was unchanged I. Almost as much (combined) of the 2 acidic metabolites, 2,4-diamino-6-(4′-carboxy-n-butylamino)pyrimidine [56828-38-7] and its 3-oxide [56828-41-2], also were produced. Smaller amounts of the glucuronide of I, 2,4-diamino-6-(4′-hydroxypiperidino)pyrimidine 3-oxide, its 3′-hydroxy isomer [56828-39-8], and 2,4-diamino-6-piperidinopyrimidine [24867-26-3] also were excreted by the rat. The major metabolite of I excreted by the dog was the 4′-hydroxy metabolite. Smaller amounts of unchanged I and polar metabolites and much smaller amounts of the glucuronide of I, the 3′-hydroxy metabolite, and 2,4-diamino-6-piperidinopyrimidine also were excreted by the dog. Evidence was obtained for a 4′-hydroxy metabolite glucuronide in this species. The major circulatory material in dog plasma was the 4′-hydroxy metabolite, whereas it was the glucuronide of I in monkey plasma. This study involved multiple reactions and reactants, such as 2,6-Diamino-4-chloropyrimidine-1-oxide (cas: 35139-67-4Application In Synthesis of 2,6-Diamino-4-chloropyrimidine-1-oxide).

Different antiviral potencies of BV-araU and related nucleoside analogs against herpes simplex virus type 1 in human cell lines and Vero cells was written by Machida, Haruhiko; Nishitani, Makiko; Suzutani, Tatsuo; Hayashi, Kozaburo. And the article was included in Microbiology and Immunology in 1991.Quality Control 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:

Antiviral potencies against herpes simplex virus type 1 (HSV-1) of 1-β-D-arabinofuranosyl-E-5-(2-bromovinyl)uracil (BV-araU) and 10 other nucleoside analogs in human embryonic lung fibroblast (HEL) cells were compared with those in Vero cells. 5-Halogenovinylarabinosyluracils, highly active in HEL cells, were inactive against all 3 laboratory-stocked strains of HSV-1 but exerted moderate antiviral effects on 3 clin. isolates in Vero cells. The reduction in anti-HSV-1 potencies of other representative nucleoside analogs in Vero cells was much less than those of 5-halogenovinylarabinosyluracils. However, significant antiviral potencies of BV-araU against laboratory strains were observed in other human and monkey fibroblast cells including an immortalized cell line. Significant enhancement of antiviral activity of BV-araU against a laboratory strain and a clin. isolate was demonstrated in Vero cells by the addition of 0.1 μM aminopterin or FUdR, an inhibitor of thymidylate synthesis. The potentiated anti-HSV-1 activity in Vero cells was comparable to the potency in HEL cells without the inhibitor. These results suggested that high activity of thymidylate synthesis and a large thymidylate pool size in Vero cells seem to be related to loss of anti-HSV-1 potency of BV-araU. Original tissue type, species, and the immortality may not be responsible for the reduced antiviral activity of BV-araU in Vero 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: 69256-17-3Quality Control of 1-((2R,3S,4R,5R)-3-Fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-5-methylpyrimidine-2,4(1H,3H)-dione).

A group of 2′-fluoro and 5-substituted arabinosyl pyrimidines and a group of base-substituted pseudoisocytidine analogs were evaluated for their capacity to induce differentiation in the human promyelocytic leukemia cell line, HL-60. These compounds were compared to 1-β-D-arabinofuranosylcytosine nAra-C) by monitoring: (1) inhibition of cell growth; (2) morphol. maturation; (3) nitroblue tetrazolium (NBT) reduction; (4) expression of a myeloid differentiation antigen, Mo1; and (5) inhibition of colony formation. Exposure of logarithmically growing cells for 5 days to Ara-C, 2′-fluoro-Ara-C (FAC), 2′-fluoro-5-methyl-Ara-C (FMAC) and 2′-fluoro-5-ethyl-Ara-C (FEAC) resulted in cell growth inhibition at 50% inhibitory concentrations of 0.007, 0.11, 1.7 and 18 μM and at cytostatic concentrations of 0.1, 0.5, 5.0 and 50 μM, resp. These compounds induced granulocytic and monocytic maturation, reduction of NBT, increased expression of Mo1 antigen and a decrease or loss of both cell proliferation and colony formation in a semisolid medium. There were few, if any, cell differentiation effects for the uracil nucleosides and pseudoisonucleosides tested. Ara-C was the most cytotoxic of the compounds When comparing absolute numbers of differentiated cells, i.e. percent of pos. cells multiplied by the number of viable cells, FAC, FMAC, and FEAC were superior to Ara-C in inducing differentiation of HL-60 cells.

A number of anti-herpes agents which are either licensed for clin. use (acyclovir  [59277-89-3]) or subject of clin. studies (bromovinyldeoxyuridine  [82768-44-3], fluoroiodoaracytidine  [69123-90-6], dihydroxypropoxymethylguanine  [82410-32-0]) or under preclin. investigation (i.e., fluoroiodoarauridine  [69123-98-4]), fluoromethylarauridine  [69256-17-3], dihydroxybutylguanine  [83470-64-8], bromovinyldeoxycytidine  [84412-83-9], bromovinylarauridine  [77181-69-2], and carbocyclic bromovinyldeoxyuridine  [95463-56-2]) were evaluated for their ability to induce sister chromatid exchange (SCE), an indicator of mutagenesis. SCE was scored on metaphasic chromosomes of human lymphocytes which had been exposed to 5-bromo-2-deoxyuridine and varying concentrations of the test compounds The antiviral assays were based on the inhibition of the cytopathogenicity of herpes simplex virus for human diploid fibroblasts. Most compounds, i.e. acyclovir, bromovinyldeoxyuridine, or carbocyclic bromovinyldeoxyuridine, did either not induce SCE or only so at concentrations far above their min. antiviral concentrations However, fluoroiodoaracytidine and dihydroxypropoxymethylguanine affected the SCE rate at a concentration (≥ 4.5 μg/mL) that is readily achievable in blood following i.v. injection.
