Preclinical investigations of FIAU, an anti-herpes agent was written by McLaren, C.; Chen, M. S.; Barbhaiya, R. H.; Buroker, R. A.; Oleson, F. B.. And the article was included in International Congress Series in 1985.Computed Properties of C10H13FN2O5 The following contents are mentioned in the article:

The pharmacol. of FIAU (I) [69123-98-4] as an anti-herpes agent is described in relation to that of FIAC (II) [69123-90-6] and FMAU (III) [69256-17-3]. The mechanism of action of I is dependent on selective inhibition of viral thymidine kinase  [9002-06-6]. The I monophosphate [99891-31-3] and III monophosphate [94344-82-8] had better affinities for cellular thymidylate kinase  [9014-43-1] than for herpes simplex virus thymidine/thymidylate kinases. However, II monophosphate [99876-43-4] had poor affinities for either the cellular or herpes simplex virus enzymes. In cells exposed to 14C-labeled II, I monophosphate was the major metabolite, indicating that II is converted to the more active agent, I. I appeared to have good activity, but it had cardiotoxic and myelosuppressive activities. 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).

And the article was included in Nucleic Acids Symposium Series in 1985.Computed Properties of C10H13FN2O5 The following contents are mentioned in the article:

Mouse mammary carcinoma FM3A cells deficient in thymidine kinase  [9002-06-6] were transformed by a cloned gene for herpes simplex virus type 1 thymidine kinase. Among several antiherpetic nucleoside analog, (E)-5-(2-bromovinyl)-2′-deoxyuridine  [69304-47-8], (E)-5-(2-iodovinyl)-2′-deoxyuridine  [69304-48-9], and (E)-5-(2-bromovinyl)-2′-deoxycytidine  [74131-09-2] inhibited the growth of the transformed cells at concentrations 5000- to 20000-fold lower than those required to inhibit the growth of their corresponding wild-type cells. The selective inhibitory action of these compounds was due to a specific phosphorylation by the viral thymidine kinase. From the transformed cells, thymidine-auxotrophic mutants that are deficient in thymidylate synthase were isolated. These mutant cell lines should prove useful in elucidating the mechanism of action of the antiherpetic nucleoside analogs. 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).

Ab initio studies of the antiviral drug 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)thymine was written by Sapse, A. M.; Snyder, G.. And the article was included in Cancer Investigation in 1985.Recommanded Product: 69256-17-3 The following contents are mentioned in the article:

The antiviral drug 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)thymine (I) [69256-17-3] exhibits a high therapeutic index against a number of herpesviruses. As with other drugs which are nucleoside analogs, such as 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)-5-iodocytosine and others, the activity seems to be strongly related to the presence of a fluorine atom in the sugar moiety, in the arabino position. Theor. calculations, using quantum-chem. methods, are used to elucidate the role of the fluorine in the arabino position and to provide information about the sugar puckering. The results seem to indicate that the fluorine atom prevents the rotation of the base around the sugar-base bond, locking it into an anti-structure which might be related to its exposure to enzymic attack. The sugar study confirms the endo-position (above the plane) of the C’-2 carbon as opposed to the endo-position of the C’-3 carbon. 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: 69256-17-3Recommanded Product: 69256-17-3).

Treatment of genital herpes simplex virus infections in guinea pigs was written by Kern, Earl R.. And the article was included in UCLA Symposia on Molecular and Cellular Biology, New Series in 1984.Application of 69256-17-3 The following contents are mentioned in the article:

Intravaginal inoculation of guinea pigs with herpes simplex virus type 2 provides an excellent model for genital herpes in humans. The infection is characterized by local viral replication in the vaginal tract followed by the appearance of vesicular lesions on external genital skin. After recovery from the primary infection, spontaneous recurrent lesions appear on the external genitalia. Oral treatment with acyclovir  [59277-89-3], 2′-deoxy-2′-fluoro-5-iodoarabinosylcytosin  [69123-90-6], 2′-fluoro-5-iodoarabinosyluracil  [69123-98-4], 2′-fluoro-5-methylarabinosyluracil  [69256-17-3], 9-(1,3-dihydroxy-2′-propoxymethyl)guanine  [82410-32-0], and i.m. treatment with recombinant human interferon-αA all reduced the severity of the primary infection. All compounds administered during recurrent disease also reduced the frequency of recurrent episodes, however, the frequency of recurrences returned to the level of controls when therapy was terminated. 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 of 69256-17-3).
