I-Motifs are four-stranded DNA structures consisting of two parallel DNA duplexes held together by hemi-protonated and intercalated cytosine base pairs (C:CH+). They have attracted considerable research interest for their potential role in gene regulation and their use as pH responsive switches and building blocks in macromol. assemblies. At neutral and basic pH values, the cytosine bases deprotonate and the structure unfolds into single strands. To avoid this limitation and expand the range of environmental conditions supporting i-motif folding, we replaced the sugar in DNA by 2-deoxy-2- fluoroarabinose. We demonstrate that such a modification significantly stabilizes i-motif formation over a wide pH range, including pH 7. NMR experiments reveal that 2-deoxy-2- fluoroarabinose adopts a C2′-endo conformation, instead of the C3′-endo conformation usually found in unmodified i-motifs. Nevertheless, this substitution does not alter the overall i-motif structure. This conformational change, together with the changes in charge distribution in the sugar caused by the electroneg. fluorine atoms, leads to a number of favorable sequential and inter-strand electrostatic interactions. The availability of folded i-motifs at neutral pH will aid investigations into the biol. function of i-motifs in vitro, and will expand i-motif applications in nanotechnol.

CE coupled with UV detection was assessed as a possible platform for the chem. identity and purity anal. of positron emission tomog. (PET) tracers using [18F]FAC and [18F]FLT as examples. Representative samples containing mixtures of the tracers plus well-known impurities, as well as real radioactive samples (formulated for injection), were analyzed. Using MEKC with SDS in a neutral phosphate buffer, the separation of all compounds in the samples was achieved with baseline resolutions in less than 4.5 min and 3 min for FLT and FAC samples, resp. In comparison to the gold-standard for chem. anal. (i.e. HPLC/UV), we have demonstrated improvements in anal. times, and comparable LOD. Although the reproducibility in migration time is slightly lower than that of the HPLC, identification of the compounds was still possible due to good peak separation In addition, we show that CE can be used to identify and quantify Krytofix2.2.2 (a toxic and commonly used phase transfer catalyst) in less than 2 min and with a LOD of 45 μg/mL (non-optimized). These results demonstrate adequate performance for chem. identity and purity anal. Combined with the potential for miniaturization into a microchip format, these results suggest the potential of CE as an integral part of a miniaturized quality control system for PET tracers.

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..

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.

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 pharmacologicl disposition and metabolic fate of 2-14C-labeled 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)thymine (FMAU)(I) [69256-17-3] and 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)-5-iodocytosine (FIAC)(II) [69123-90-6] were compared after giving each of the substances i.v. or orally. Most of the radioactivity of these substances is excreted in urine within 24 h after administration in mice and rats. During the same period, the recovery in feces and respiratory CO2 is, for each, < 5%. Biliary excretion from the common bile duct of rats is low, 2 to 4% of dose during the first 5 h after i.v. injection. Chromatog. anal. of 24-h urine collections after giving FMAU reveals that most of the radioactivity in mouse and rat urine is present as unchanged drug. Mouse urine also contains significant amounts of 3 unidentified metabolites of FMAU; these have also been detected in mouse plasma and in rat urine. Chromatog. analyses of plasma and urine samples from mice and rats given FIAC show that this substance is substantially transformed by deamination into a major metabolite, 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)-5-ioduracil  [69123-98-4]. Deiodinated metabolites have also been detected, namely, 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)cytosine  [56632-83-8] and 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)uracil  [69123-94-0]. Radioactivity in extracerebral organs of rats receiving labeled FIAC or FMAU is, within 10 min after i.v. injection, maximal and in concentrations equivalent to or higher than in plasma. Maximal concentrations after oral doses are reached within 30 to 60 min. At later times, rates of decrease in extracerebral organs parallel those in plasma. Half-lives after oral doses are higher than after i.v. doses. Penetration of radioactivity into rat brain is rapid, and the ratio of brain to plasma concentrations increases steadily to over 0.5 during the first 6 h after dosing. Substantially greater concentrations appear in brain after FMAU than after FIAC. Studies of radioactivity remaining in various portions of the gut of rats given oral doses of the labeled drugs suggest that most of the absorption takes place from the stomach or upper end of the small intestine. In dogs, the rates of renal clearance of FMAU and FIAC are less than 20% that of creatine when plasma concentrations are 10-fold greater than that inhibiting herpes virus replication in vitro by 90%. Nearly all of the radioactivity excreted in dog urine during the first 24 h after i.v. [2-14C]FMAU consists of unchanged drug. After [2-14C]FIAC, the 24-h urinary radioactivity is composed primarily of unchanged drug and the deiodinated metabolites, 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)cytosine and 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)uracil; only trace amounts of the deaminated product, 1-(2-fluoro-2-deoxy-β-D-arabinofuranosyl)-5-iodouracil, were detected. The synthesis of [2-14C]FMAU [83374-60-1] is described.

Nucleoside analogs with modified sugar moieties have been examined for their substrate/inhibitor specificities towards highly purified deoxycytidine kinase (dCK) and thymidine kinases (tetrameric high-affinity form of TK1-cytoplasmic and TK2-mitochondrial) from human leukemic spleen. In particular, the analogs included the mono- and di-O’-Me derivatives of dC, dU and dA, syntheses of which are described. In general, purine nucleosides with modified sugar rings were feebler substrates than the corresponding cytosine analogs. Sugar-modified analogs of dU were also relatively poor substrates of TK1 and TK2, but were reasonably good inhibitors, with generally lower Ki values vs TK2 than TK1. An excellent discriminator between TK1 and TK2 was 3′-hexanoylamino-2′,3′-dideoxythymidine, with a Ki of ∼600 μM for TK1 and ∼0.1 μM for TK2. 3′-OMe-dC was a superior inhibitor of dCK to its 5′-O-Me congener, consistent with possible participation of the oxygen of the (3′)-OH or (3′)-OMe as proton acceptor in hydrogen bonding with the enzyme. Surprisingly α-dT was a good substrate of both TK1 and TK2, with Ki values of 120 and 30 μM for TK1 and TK2, resp.; and a 3′-branched α-L-deoxycytidine analog proved to be as good a substrate as its α-D-counterpart. Several 5′-substituted analogs of dC were good non-substrate inhibitors of dCK and, to a lesser extent, of TK2. Finally, some ribonucleosides are substrates of the foregoing enzymes; in particular C is a good substrate of dCK, and 2′-OMe-C is an even better substrate than dC.

Hepatitis C virus afflicts approx. 180 million people worldwide and currently there are no direct acting antiviral agents available to treat this disease. Our first generation nucleoside HCV inhibitor, RG7128 has already established proof-of-concept in the clinic and is currently in phase IIb clin. trials. As part of our continuing efforts to discover novel anti-HCV agents, 3′,4′-oxetane cytidine and adenosine nucleosides were prepared as inhibitors of HCV RNA replication. These nucleosides were shown not to be inhibitors of HCV as determined in a whole cell subgenomic replicon assay. However, 2′-mono/diflouro analogs were readily phosphorylated to their monophosphate metabolites by deoxycytidine kinase and their triphosphate derivatives were shown to be inhibitors of HCV NS5B polymerase in vitro. Lack of anti-HCV activity in the replicon assay may be due to the inability of the monophosphates to be converted to their corresponding diphosphates.
