The reaction kinetics and specificity of human and canine liver cytidine deaminase (I) for the virucide 1-(2′-deoxy-2′-fluoro-β-D-arabinofuranosyl)-5-iodocytosine (FIAC) and some other 5-substituted arabinofuranosylcytosine analogs are reported. The Km and Vmax values of human and canine I for FIAC differed significantly; marked kinetic differences of human and canine I were also observed with cytidine, deoxycytidine, arabinofuranosylcytidine, and deoxyfluoroarabinofuranosylcytosine. Studies with human I showed that substitution at the 5-position affected enzyme activity. Thus, although deoxyfluoroarabinofuranosylethylcytosine is a potent antiviral compound in vitro, it was not deaminated by human I. 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: 56632-83-8Name: 4-Amino-1-((2R,3S,4R,5R)-3-fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)pyrimidin-2(1H)-one).

Structural requirements for the enzymic deamination of cytosine nucleosides was written by Kreis, W.; Watanabe, K. A.; Fox, J. J.. And the article was included in Helvetica Chimica Acta on April 19,1978.SDS of cas: 56632-83-8 The following contents are mentioned in the article:

Thirty-three 1-β-D-pentofuranosylcytosine nucleosides were examined as substrates of crude cytidine deaminase from mouse kidney. Modification of the aglycone moiety by substitution of a F atom at C(5) resulted in a several-fold increase in the deamination velocity relative to cytidine, whereas insertion of a Me group at C(5) decreased the deamination velocity. This decrease was even more pronounced when a Me group was substituted at C(6). Though xylosylcytosine and 3′-deoxy-3′-fluoroxylocytosine were not substrates for this deaminase, those xylofuranosylcytosines bearing good leaving groups (e.g., bromo, mesyloxy, or tosyloxy) at C(3′) were deaminated with substantial deamination velocities. This is probably due to a prior chem. reaction leading to arabino nucleosides bearing a free 3′-OH in a down configuration. A different situation was obtained with arabino nucleosides. Though 1-β-D-arabinofuranosylcytosine and 2′-deoxy-2′-fluoro-1-β-D-arabinofuranosylcytosine were substrates for this deaminase, substitution of bulky groups (e.g., chloro, bromo, or mesyloxy) at C(2′) substantially decreased the susceptibility to deamination. A hypothesis is offered to explain these differences between xylo- and arabino-cytosines. The presence of a free OH group at the 5′-position is not essential for enzymic deamination. 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).

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).

Pharmacological disposition and metabolic fate of 2′-fluoro-5-iodo-1-β-D-arabinofuranosylcytosine in mice and rats was written by Chou, Ting-Chao; Feinberg, Aaron; Grant, Alan J.; Vidal, Pedro; Reichman, Uri; Watanabe, Kyoichi A.; Fox, Jack J.; Philips, Frederick S.. And the article was included in Cancer Research on September 30,1981.Name: 4-Amino-1-((2R,3S,4R,5R)-3-fluoro-4-hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)pyrimidin-2(1H)-one The following contents are mentioned in the article:

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.

The hepatitis C virus (HCV) RNA polymerase, NS5B, is a leading target for novel and selective HCV drug design. The enzyme has been the subject of intensive drug discovery aimed at developing direct acting antiviral (DAA) agents that inhibit its activity and hence prevent the virus from replicating its genome. In this study, we focus on one class of NS5B inhibitors, namely nucleos-(t)-ide mimetics. Forty-one distinct nucleotide structures have been modeled within the active site of NS5B for the six major HCV genotypes. Our comprehensive modeling protocol employed 287 different mol. dynamics simulations combined with the mol. mechanics/Poisson-Boltzmann surface area (MM-PBSA) methodol. to rank and analyze these structures for all genotypes. The binding interactions of the individual compounds have been investigated and reduced to the at. level. The present study significantly refines our understanding of the mode of action of NS5B-nucleotide-inhibitors, identifies the key structural elements necessary for their activity, and implements the tools for ranking the potential of addnl. much needed novel inhibitors of NS5B.

Human telomeres and promoter regions of genes fulfill a significant role in cellular aging and cancer. These regions comprise of guanine and cytosine-rich repeats, which under certain conditions can fold into G-quadruplex (G4) and i-motif structures, resp. Herein, we use UV, CD and NMR spectroscopy to study several human telomeric sequences and demonstrate that G4/i-motif-duplex interconversion kinetics are slowed down dramatically by 2′-β-fluorination and the presence of G4/i-motif-duplex junctions. NMR-monitored kinetic experiments on 1:1 mixtures of native and modified Cand G-rich human telomeric sequences reveal that strand hybridization kinetics are controlled by G4 or i-motif unfolding. Furthermore, we provide NMR evidence for the formation of a hybrid complex containing G4 and i-motif structures proximal to a duplex DNA segment at neutral pH. While the presence of i-motif and G4 folds may be mutually exclusive in promoter genome sequences, our results suggest that they may co-exist transiently as intermediates in telomeric sequences.
