A novel mass spectrometric method was applied to rapid, accurate (<1%) quantification of chiral Clevudine (L-FMAU, 2'-fluoro-5-methyl-β,L-arabinofuranosyluracil), a potent antiviral nucleoside agent against hepatitis B virus. Transition metal bound complex ions containing the chiral drug are generated by electrospray ionization mass spectrometry and subjected to collision-induced dissociation The ratio of the two competitive dissociation rates is related to the enantiomeric composition of the drug mixture, allowing the determination of enantiomeric contamination in the drug. 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: 69256-17-3HPLC of Formula: 69256-17-3).

2′-Fluoro-5-iodo-1-β-D-arabinofuranosylcytosine-HCl (FIAC)(I) [69123-90-6] was synthesized and labeled with 14C in the 2 position for the study of pharmacol. disposition and metabolic fate. FIAC is deaminated by cytosine nucleoside deaminase [9025-06-3] at a rate comparable to that of 1-β-D-arabinofuranosylcytosine. The deaminated product, 2′-fluoro-5-iodo-1-β-D-arabinofuranosyluracil (FIAU) [69123-98-4] is, like FIAC, an active antiviral agent. After i.v. injection of [2-14C]-FIAC in mice, most of the radioactivity in plasma appears as FIAU. In i.v.-injected rats which lack cytosine nucleoside deaminase, plasma radioactivity is largely present in unchanged FIAC. If mice are pretreated with tetrahydrouridine, an inhibitor of the nucleoside deaminase, plasma radioactivity is mostly FIAC. The radioactivity of [2-14C]-FIAC injected i.v. is excreted in urine, at 63 to 93% of the dose in mice and >90% of the dose in rats within 0 to 24 h. Most of the radioactivity in urine of rats and in mice pretreated with tetrahydrouidine is present as unchanged FIAC; in control mice, most of the radioactivity is found as FIAU. Chromatog. anal. of urine from control mice receiving labeled FIAC has revealed that radioactivity is present in the following nucleosides: FIAC (14.5); FIAU (73); 2′-fluoro-5-methyl-1-β-D-arabinofuranosyluracil (FMAU) [69256-17-3] (5.4); and 2′-fluoro-1-β-D-arabinofuranosyluracil [69123-94-0] (2.3%). These metabolites are also present in acid-soluble fractions of mouse blood, small intestine, and liver. Like FIAC and FIAU, FMAU is a potent antiherpetic agent. Only âˆ?.3% of the radioactivity of injected [2-14C]-FIAC appears in mouse respiratory CO2; degradation to CO2 can be blocked by tetrahydrouridine. Less than 2% of the total radioactivity is excreted in bile in rats. Small amounts of radioactivity are also recovered in feces, mostly in deaminated products. FIAC and FIAU, with a 2′-F substituent in the arabino configuration, are less susceptible to metabolic glycosyl cleavage than is 5-iodo-2′-deoxyuridine. The radioactivity of [2-14C]-FIAC is incorporated into DNA fractions of highly proliferating organs such as intestine, spleen, and thymus, although preliminary results indicate that the substances incorporated are arabinofuranosyl nucleoside metabolites of FIAC. 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).

2′-Deoxy-2′-fluoro-β-D-arabinonucleosides and oligonucleotides (2’F-ANA): synthesis and physicochemical studies was written by Wilds, Christopher J.; Damha, Masad J.. And the article was included in Nucleic Acids Research on September 15,2000.Electric Literature of C9H12FN3O4 The following contents are mentioned in the article:

Recently, hybrids of RNA and D-arabinonucleic acids (ANA) as well as the 2′-deoxy-2′-fluoro-D-arabinonucleic acid analog (2’F-ANA) were shown to be substrates of RNase H. This enzyme is believed to be involved in the primary mechanism by which antisense oligonucleotides cause a reduction in target RNA levels in vivo. To gain a better understanding of the properties of arabinose based oligonucleotides, we have prepared a series of 2’F-ANA sequences of homopolymeric (A and T) and mixed base composition (A, T, G and C). UV thermal melting and circular dichroic (CD) studies were used to ascertain the thermodn. stability and helical conformation of 2’F-ANA/RNA and 2’F-ANA/DNA hybrids. It is shown that 2’F-ANA has enhanced RNA affinity relative to that of DNA and phosphorothioate DNA. The 2′-fluoroarabino modification showed favorable pairing to single-stranded DNA also. This is in sharp contrast to ANA, which forms weak ANA/DNA hybrids at best. According to the measured thermodn. parameters for duplex formation, the increased stability of hybrids formed by 2’F-ANA (e.g., 2’F-ANA/RNA) appears to originate from conformational pre-organization of the fluorinated sugars and a favorable enthalpy of hybridization. In addition, NMR spectroscopy revealed a five-bond coupling between the 2’F and the base protons (H6/H8) of 2′-deoxy-2′-fluoro-β-D-arabinonucleosides. This observation is suggesting of a through-space interaction between 2’F and H6/H8 atoms. CD experiments indicate that 2’F-ANA/RNA hybrids adopt an ‘A-like’ structure and show more resemblance to DNA/RNA hybrids than to the pure RNA/RNA duplex. This feature is believed to be an important factor in the mechanism that allows RNase H to discriminate between 2’F-ANA/RNA (or DNA/RNA) and RNA/RNA duplexes. 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: 56632-83-8Electric Literature of C9H12FN3O4).

The pyrimidine derivatives can easily interact with enzymes, genetic materials, and bio components within the cell. 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 C9H12FN3O4

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).

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 ≫ I > vidarabine ≃ 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.

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.

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.

The inhibition of ultraviolet radiation-induced DNA repair in human diploid fibroblasts by arabinofuranosyl nucleosides was written by Snyder, Ronald D.; Van Houten, Bennett; Regan, James D.. And the article was included in Chemico-Biological Interactions on June 30,1984.Computed Properties of C10H13FN2O5 The following contents are mentioned in the article:

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 inhibition of ultraviolet radiation-induced DNA repair in human diploid fibroblasts by arabinofuranosyl nucleosides was written by Snyder, Ronald D.; Van Houten, Bennett; Regan, James D.. And the article was included in Chemico-Biological Interactions on June 30,1984.Related Products of 56632-83-8 The following contents are mentioned in the article:

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 4-Amino-1-((2R,3S,4R,5R)-3-fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)pyrimidin-2(1H)-one (cas: 56632-83-8Related Products of 56632-83-8).
