Substrate/inhibitor specificities of nucleoside analogs with modified sugar moieties towards highly purified deoxycytidine kinase (dCK) and thymidine kinases (TK1 and TK2) from human leukemic spleen have been examined Substrate activities of cytosine nucleosides vs. dCK were as follows: 2′-fluoro-dC > 2′-O-methyl-C > araC > 2′-fluoro-2′-deoxy-araC > 3′-O-methyl-dC = 3′-fluoro-2′,3′-ddC > cytosine β-L-riboside > 2′,3′-ddC > C= 1-(4-hydroxy-1,2-butadienyl)-cytosine (cytallene) = 2′-azido-dC. Modified purine nucleosides were only feeble substrates: ara-A > 2′-fluoro-2′-3′-dideoxy-ara-A = 2′-O-methyl-A. With TK1 and TK2, similar sugar-modified analogs of dU and dT were feeble substrates. Surprisingly α-dT was a relatively good substrate, as well some β-L-ribonucleosides. Several 5′-substituted analogs of dC were good non-substrate inhibitors of dCK and, to a lesser extent, of TK2. The overall data are relevant to the role of these enzymes in “”activation”” (by phosphorylation) of nucleoside analogs with antiviral and antitumor activities. 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: 56632-83-8Reference of 56632-83-8).

Drug resistant and hypersensitive herpes simplex virus mutants: isolation and application to dissection of the pol locus was written by Coen, Donald M.; Chiou, Henry C.; Fleming, H. Edward Jr.; Leslie, Laurel K.; Retondo, Margaret J.. And the article was included in UCLA Symposia on Molecular and Cellular Biology, New Series in 1984.Category: pyrimidines The following contents are mentioned in the article:

Herpes simplex virus mutants resistant to antiviral drugs and aphidicolin are readily isolated in a single-step selection procedure. However, it was found that mutants resistant to one drug are often not substantially cross-resistant to others suggesting possible solutions to potential clin. resistance. Repeated plaque purification has proven essential for such analyses. Previous studies have identified PAA-, ACG-, and araA-resistance mutations in the DNA polymerase (pol) locus. Mutations conferring hypersensitivity to araA, PAA, FMAU, FIAU, BVdU, 2’NDG, and aphidicolin (Aph) were identified and several of these were mapped to the pol locus. The existence of either type of mutation in the pol locus implies that polymerase is a target for the drugs or otherwise mediates drug-sensitivity. Addnl., cross-resistance patterns of the mutants suggest that polymerases capable of discriminating against one nucleoside analog are incapable of discriminating against closely related compounds Mutations conferring altered sensitivity to the same drug map at different locations in the pol locus. Anal. of these mutations should aid in the functional dissection of the polymerase. 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: 69256-17-3Category: pyrimidines).

Minoxidil (2,4-diamino-6-piperidinopyrimidine 3-oxide) was primarily recognized as a drug for reducing vascular resistance to blood flow. It was later introduced as a more important medicine for topical stimulation of hair growth and baldness reverting as well as treatment of androgenic alopecia through increasing prostaglandin endoperoxide synthesis. In this study, magnetic nanoparticles (MNPs) of spinel ferrites (MFe2 O4, M = Co, Ni, Fe, Cu, and Zn) via solid-state grinding procedure were prepared and then characterized using X-ray diffraction, SEM, transmission electron microscopy, vibrating sample magnetometer, and Fourier transform IR techniques. The prepared nanoferrites were utilized as efficient and green heterogeneous catalysts for N -oxidation of 2,6-diamino-4-chloro-pyrimidine with H2 O2 in refluxing ethanol giving 2,6-diamino-4-chloro-pyrimidine N -oxide as a starting material for the synthesis of 2,4-diamino-6-piperidinopyrimidine 3-oxide (minoxidil). Among the examined nanoferrites, CoFe2 O4 MNPs exhibited prominent catalytic activity giving the product in 95% yield within 60 min.

18F-FAC (1-(2′-deoxy-2′-[18F]fluoro-β-D-arabinofuranosyl)-cytosine) is an important 2′-fluoro-nucleoside-based positron emission tomog. (PET) tracer that has been used for in vivo prediction of response to the widely used cancer chemotherapy drug gemcitabine. Previously reported synthetic routes to 18F-FAC have relied on early introduction of the 18F radiolabel prior to attachment to protected cytosine base. Considering the 18F radiochem. half-life (110 min) and the tech. challenges of multi-step syntheses on PET radiochem. modular systems, late-stage radiofluorination is preferred for reproducible and reliable radiosynthesis with in vivo applications. Herein, we report the first late-stage radiosynthesis of 18F-FAC. Cytidine derivatives with leaving groups at the 2′-position are particularly prone to undergo anhydro side-product formation upon heating because of their electron d. at the 2-carbonyl pyrimidone oxygen. Our rationally developed fluorination precursor showed an improved reactivity-to-stability ratio at elevated temperatures 18F-FAC was obtained in radiochem. yields of 4.3-5.5% (n = 8, decay-corrected from end of bombardment), with purities ≥98% and specific activities ≥63 GBq/μmol. The synthesis time was 168 min.

The purpose of this study was to develop an anal. method for the determination of 2′-fluoro-5-methyl-β-l-arabinofuranosyl uracil triphosphate (L-FMAU-TP) in human peripheral blood mononuclear cells (PBMCs), and its application in the determination of cellular levels of L-FMAU-TP in PBMCs isolated from patients treated with 2′-fluoro-5-methyl-β-l-arabinofuranosyl uracil (L-FMAU). An ion-pairing liquid chromatog. (IPC) method, coupled with neg. ion electrospray ionization tandem mass spectrometry (ESI-MS/MS), was developed for the accurate and repeatable detection of L-FMAU-TP, with a limit of detection of 1.6 pmol/106 cells. The calibration curve for L-FMAU-TP was linear over the concentration range 1.6 to 80 pmol/106 cells. The intra- and inter-day precision was lower than 11.2%, and the accuracy was between 97.1 and 106.9%. When applied to the determination of L-FMAU-TP in PBMCs isolated from HBV-infected patients undergoing L-FMAU treatment, the levels reached a steady state concentration 4 wk after daily single oral administration of 20 mg L-FMAU, and these levels were maintained for up to 12 wk, but then decreased 12 wk after drug cessation. The terminal half-life of L-FMAU-TP in PBMCs after drug cessation was estimated to be 15.6 days.

Effect of eight antiviral drugs on the reactivation of herpes simplex virus in explant cultures of latently infected mouse trigeminal ganglia was written by Klein, Richard J.; Friedman-Kien, Alvin E.. And the article was included in Journal of Investigative Dermatology in 1984.COA of Formula: C10H13FN2O5 The following contents are mentioned in the article:

The effect of several antiviral drugs on the reactivation of herpes simplex virus type 1 in explant cultures of latently infected mouse trigeminal ganglia was investigated. Phosphonoacetate  [4408-78-0] and phosphonoformate  [4428-95-9] which act directly on the virus-induced DNA polymerase, require a drug concentration of 400 μg/mL for the inhibition of virus reactivation in latently infected ganglia. Arabinosyladenine  [5536-17-4] and arabinosyladenine monophosphate  [29984-33-6], which are phosphorylated to triphosphates by cellular enzymes and inhibit virus synthesis either by blocking the DNA polymerase or by incorporation into viral DNA, require a concentration of only 100 μg/mL for the inhibition of the reactivation process. Drugs that are phosphorylated by the virus-induced thymidine kinase, such as acyclovir  [59277-89-3], arabinosylthymine  [605-23-2], bromovinyldeoxyuridine  [69304-47-8], and three fluorinated pyrimidine nucleosides require the lowest drug concentrations for complete inhibition of virus reactivation in latently infected ganglia explant cultures. These data suggest that the inhibition of virus reactivation is dependent not only on drug concentration, but also on the number of latently infected neurons in the ganglia. 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: 69256-17-3COA of Formula: C10H13FN2O5).

Using a Systematic Evolution of Ligands by Exponential Enrichment (SELEX) protocol capable of selecting xeno-nucleic acid (XNA) aptamers, a 2′-deoxy-2′-fluoroarabinonucleotide (FANA) aptamer (referred to as FA1) to HIV-1 reverse transcriptase (HIV-1 RT) was selected. FA1 bound HIV-1 RT with K D, apparatus values in the low pM range under different ionic conditions. Comparisons to published HIV-1 RT RNA and DNA aptamers indicated that FA1 bound at least as well as these aptamers. FA1 contained a 20 nucleotide 5′ DNA sequence followed by a 57 nucleotide region of FANA nucleotides. Removal of the fourteen 5′ DNA nucleotides did not affect binding. FA1’s predicted structure was composed of four stems and four loops. All stem nucleotides could be modified to G-C base pairs (14 total changes) with a small effect on binding. Eliminating or altering most loop sequences reduced or abolished tight binding. Overall, results suggested that the structure and the sequence of FA1 were important for binding. FA1 showed strong inhibition of HIV-1 RT in extension assays while no specific binding to avian myeloblastosis or Moloney murine leukemia RTs was detected. A complete DNA version of FA1 showed low binding to HIV-1 RT, emphasizing the unique properties of FANA in HIV-1 RT binding.

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.
