    ABSTRACT: We report the synthesis, incorporation into oligonucleotides, and base-pairing properties of the 2-thio-variant of iso-guanine. Iso-guanine is the purine component of a nonstandard base pair with 5-methyl-iso-cytosine. The 2-thio-iso-guanine•5-methyl-iso-cytosine base pair is found to have similar stability to an adenine•thymine pair.

    ABSTRACT: In this paper, the risk of the preparation of artificial DNAs via an interrupted automated solid-phase triester procedure is discussed. These results differ completely from the corresponding results obtained by a gradual non-automated synthesis, indicated as solution-phase chemistry. With experimental results focused on model systems under various conditions and molecular-mechanics calculations, it feels as a challenge to offer an explanation for this different behavior. Attention is briefly given to click-linked DNA fragments as a substitute of phosphate linkages.

    ABSTRACT: A simple and inexpensive procedure has been developed for the selective formation of 1,4-disubstituted-1,2,3-triazolo-nucleosides starting from organic azides and terminal alkynes, mediated by in situ generated copper(I) catalyst from readily available CuSO4 and KI.

    ABSTRACT: Three triazole-linked nonionic xylo-nucleoside dimers T(L)-t-T(xL), T(L)-t-A(BzxL) and T(L)-t-C(BzxL) have been synthesized for the first time by Cu(I) catalyzed azide-alkyne [3 + 2] cycloaddition reaction (CuAAC) of 1-(3'-azido-3'-deoxy-2'-O,4'-C-methylene-β-D-ribo-furanosyl)thymine with different alkynes, i.e., 1-(5'-deoxy-5'-C-ethynyl-2'-O,4'-C-methylene-β-D-xylofuranosyl)thymine, 9-(5'-deoxy-5'-C-ethynyl-2'-O,4'-C-methylene-β-D-xylo-furanosyl)-N6-benzoyladenine and 1-(5'-deoxy-5'-C-ethynyl-2'-O,4'-C-methylene-β-D-xylofuranosyl)-N4-benzoylcytosine in 90%-92% yields. Among the two Cu(I) reagents, CuSO4.5H2O-sodium ascorbate in THF:(t)BuOH:H2O (1:1:1) and CuBr.SMe2 in THF used for cycloaddition (click) reaction, the former one was found to be better yielding than the latter one.

    ABSTRACT: A series of novel nucleosides bearing a 1,2,3-triazole moiety at the 2'-position of the sugar moiety has been synthesized starting from 2'-azidouridine and using the copper (I)-catalyzed Huisgen-Sharpless-Meldal 1,3-dipolar cycloaddition reaction. The reactions proceeded in overall yield of 52-82% and gave almost exclusively the 1,4-disubstituted 1,2,3-triazoles. The 2'-azidouridine was synthesized from uridine in two steps, and reacted with a variety of differently substituted alkynes to give the desired 2'-triazole-substituted uridine derivatives.

    ABSTRACT: Modifications of the 5'-position of adenosine have been prepared via a novel 5'-carboxaldehyde synthon. The described methodology should prove useful for making related compounds in which amine-derived moieties off the 5'-position of adenosine (or related nucleoside congeners) can be easily incorporated via reductive amination, especially for the incorporation of aromatic amines.

    ABSTRACT: RNA has attracted recent attention for its key role in gene expression and hence targeting by small molecules for therapeutic intervention. This study is aimed to elucidate the specificity of RNA binding affinity of parent compound of N-arylhydroxamic acids series, N-phenylbenzohydroxamic acid trivially named as PBHA,C6H5NOH.C6H5C ˭ O. The binding behavior was examined by various biophysical methods such as absorption, fluorescence, and viscosity measurements. Molecular docking was also done. The value of affinity constant and overall binding constant was calculated 5.79 ± 0.03 × 10(4) M(-1) and K' = 1.09 ± 0.03 × 10(5) M(-1), respectively. The Stern-Volmer constant Ksv obtained was 2.28 ± 0.04 × 10(4) M(-1). The compound (PBHA) shows a concentration-based enhancement of fluorescence intensity with increasing RNA concentration. Fluorescence quenching of PBHA-RNA complex in presence of K4 [Fe(CN)6] was also observed. Viscometric studies complimented the UV results where a continuous increase in relative viscosity of the RNA solution was observed with added optimal PBHA concentration. All the experimental evidences indicate that PBHA can strongly bind to RNA through an intercalative mode.

    ABSTRACT: Novel nucleoside analogues containing photoswitchable moieties were prepared using 'click' cycloaddition reactions between 5'-azido-5'-deoxythymidine and mono- or bis-N-propargylamide-substituted azobenzenes. In solution, high to quantitative yields were achieved using 5 mol% Cu(I) in the presence of a stabilizing ligand. 'Click' reactions using the monopropargylamides were also effected in the absence of added cuprous salts by the application of liquid assisted grinding (LAG) in metallic copper reaction vials. Specifically, high speed vibration ball milling (HSVBM) using a 3/32(″) (2.38 mm) diameter copper ball (62 mg) at 60 Hz overnight in the presence of ethyl acetate lead to complete consumption of the 5'-azido nucleoside with clean conversion to the corresponding 1,3-triazole.

    ABSTRACT: We report the synthesis of novel thiopurine pyranonucleosides. Direct coupling of silylated 6-mercaptopurine and 6-thioguanine with the appropriate pyranoses 1a-e via Vorbrüggen nucleosidation, gave the N-9 linked mercaptopurine 2a-e and thioguanine 4a-e nucleosides, while their N-7 substituted congeners 10a-e and 7a-e, were obtained through condensation of the same acetates with 6-chloro and 2-amino-6-chloropurines, followed by subsequent thionation. Nucleosides 3a-e, 5a-e, 8a-e, and 11a-e were evaluated for their cytostatic activity in three different tumor cell proliferative assays.

    ABSTRACT: We proposed that metal-coordinating nucleotides could be used to control the assembly of G-quadruplexes through the formation of an artificial metal-centered quartet. Several guanine-rich DNA sequences containing 1,2,4-triazole-functionalized nucleotides were investigated. These oligonucleotides were designed to form quartets mediated by metal-triazole bonding both on the surface of and within the G-quadruplex core. In contrast to duplex studies in which 1,2,4-triazole nucleosides serve as a mimic of Watson-Crick base-pairs, our results show that these nucleosides are not suitable components of an artificial metal-centered quartet.

    ABSTRACT: To test the hypothesis that a fall in cellular ATP following stimulation of endothelial cells with thrombin is secondary to a decrease in NAD levels caused by poly(ADP-Ribose)polymerase (PARP), we measured the levels of NAD and ATP in endothelial cells after treatment with thrombin, the Ca(++)-ionophore A23187, or hydrogen peroxide (H2O2), and compared the effects of inhibitors of PARP, NAD synthesis, and ADP-ribose breakdown on these responses. Neither thrombin nor A23187 caused a reduction in endothelial NAD levels and A23187 affected ATP levels independently of NAD levels or PARP activity. H2O2 induced lowering of NAD caused modest lowering of ATP but marked additional ATP-lowering, independent of PARP and NAD, was also demonstrated. We conclude that in endothelial cells ATP levels are largely independent of NAD and PARP, which do not play a role in thrombin or Ca(++)-ionophore-mediated lowering of ATP. H2O2 caused ATP lowering through a similar mechanism as thrombin and A23187 but, additionally, caused a further ATP lowering through its intense stimulation of PARP and marked lowering of NAD.

    ABSTRACT: The photochemical behavior of 2-azidopurine 2',3',5'-tri-O-acetylribonucleoside has been investigated in aqueous solution under aerobic and anaerobic conditions. The two major processes under anaerobic irradiation of 2-azidopurine 2',3',5'-tri-O-acetylribonucleoside involve unprecedented transformation into 1-(5'-O-acetyl-β-D-ribofuranosyl)-5-[(2-oxo-1,3,5-oxadiazocan-4-ylidene)amino]-1H-imidazole-4-carbaldehyde and photoreduction to respective 2-aminopurine derivative, whereas under aerobic conditions these two processes occur to a much lesser extent and photooxidation to respective 2-nitropurine derivative dominates. The structures of photoproducts formed were confirmed by NMR and high-resolution electrospray ionization mass spectral data.

    ABSTRACT: Adenosine 5'-phosphosulfate reductase (APR) is an iron-sulfur enzyme that is vital for survival of Mycobacterium tuberculosis during dormancy and is an attractive target for the treatment of latent tuberculosis (TB) infection. The 4Fe-4S cluster is coordinated to APR by sulfur atoms of four cysteine residues, is proximal to substrate, adenosine 5'-phopsphosulfate (APS), and is essential for catalytic activity. Herein, we present an approach for the development of a new class of APR inhibitors. As an initial step, we have employed an improved solid-phase chemistry method to prepare a series of N(6)-substituted adenosine analogues and their 5'-phosphates as well as adenosine 5'-phosphate diesters bearing different Fe and S binding groups, such as thiols or carboxylic and hydroxamic acid moieties. Evaluation of the resulting compounds indicates a clearly defined spacing requirement between the Fe-S targeting group and adenosine scaffold and that smaller Fe-S targeting groups are better tolerated. Molecular docking analysis suggests that the S atom of the most potent inhibitor may establish a favorable interaction with an S atom in the cluster. In summary, this study showcases an improved solid-phase method that expedites the preparation of adenosine and related 5'-phosphate derivatives and presents a unique Fe-S targeting strategy for the development of APR inhibitors.

    ABSTRACT: Myasthenia gravis (MG) is characterized clinically by skeletal muscle fatigue following the excessive exercise. Interestingly most of MG patients manifest parallely also some abnormalities of the thymus.AMP-deaminase (AMPD) from human thymus was not a subject of studies up to now. In this paper, mRNA expression and some physico-chemical and immunological properties of AMPD purified from the thymus of MG patients were described. Experiments performed identified the liver isozyme (AMPD2) as the main isoform of AMPD expressed in this organ. The activity of AMPD found in this organ was higher than in other human non-(skeletal) muscle tissues indicating on role the enzyme may play in supplying of guanylates required for the intensive multiplication of thymocytes.
