And the article was included in Journal of Pharmaceutical and Biomedical Analysis on November 5,2007.Product Details of 13146-72-0 The following contents are mentioned in the article:

Didanosine is an antiviral drug. During the preparation of didanosine in our lab, six process related known impurities and one unknown impurity were detected in HPLC anal. at levels ranging from 0.05 to 0.8%. The same unknown impurity was also observed in com. batches. This new impurity was isolated by preparative HPLC and co-injected with didanosine sample to confirm the retention times in HPLC. This impurity was characterized as, 9-(2,3,5-trideoxy-β-D-glycero-pentofuranosyl)-9H-purin-6-one (2′,3′,5′-trideoxyinosine). Structural elucidation of this impurity by spectral data (1H NMR, 13C NMR, MS, and IR) has been discussed. This study involved multiple reactions and reactants, such as 9-((2R,3R,5S)-3-Hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-ol (cas: 13146-72-0Product Details of 13146-72-0).

9-((2R,3R,5S)-3-Hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-ol (cas: 13146-72-0) belongs to tetrahydrofuran derivatives. Tetrahydrofurans and furans are important oxygen-containing heterocycles that often exhibit interesting properties for biological applications or applications in the cosmetic industry. THF can also be synthesized by catalytic hydrogenation of furan. This allows certain sugars to be converted to THF via acid-catalyzed digestion to furfural and decarbonylation to furan, although this method is not widely practiced. THF is thus derivable from renewable resources.Product Details of 13146-72-0

Method development and validation for the analysis of didanosine using micellar electrokinetic capillary chromatography was written by Mallampati, Swapna; Leonard, Stefanie; De Vulder, Sabine; Hoogmartens, Jos; Van Schepdael, Ann. And the article was included in Electrophoresis on November 30,2005.Synthetic Route of C10H12N4O4  The following contents are mentioned in the article:

A selective MEKC method was developed for the anal. of didanosine in bulk samples. Successful separation of didanosine from 13 of its potential impurities, derived from the various synthetic preparation procedures, was achieved. As CZE gave poor separation selectivity, MEKC was preferable. The use of EKC allowed achievement of the separation in a significantly shorter time than conventional HPLC. An anionic long-chain surfactant, lithium dodecyl sulfate (LiDS), was used as the pseudostationary phase and sodium tetraborate buffer as the aqueous phase. To obtain the optimal conditions and to test the method robustness, a central composite response surface modeling experiment was performed. The optimized electrophoretic conditions include the use of an uncoated fused-silica capillary with a total length of 40 cm and an ID of 50 μm, a BGE containing 40 mM sodium tetraborate and 110 mM LiDS at pH 8.0, an applied voltage of 18.0 kV, and the capillary temperature maintained at 15°C. The method was found to be robust. The parameters for validation such as linearity, precision, and sensitivity are also reported. Three com. bulk samples were analyzed with this system. This study involved multiple reactions and reactants, such as 9-((2R,3R,5S)-3-Hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-ol (cas: 13146-72-0Synthetic Route of C10H12N4O4 ).

The Chemoenzymic Synthesis of 2-Chloro- and 2-Fluorocordycepins was written by Denisova, Alexandra O.; Tokunova, Yulia A.; Fateev, Ilja V.; Breslav, Alexandra A.; Leonov, Vladimir N.; Dorofeeva, Elena V.; Lutonina, Olga I.; Muzyka, Inessa S.; Esipov, Roman S.; Kayushin, Alexey L.; Konstantinova, Irina D.; Miroshnikov, Anatoly I.; Stepchenko, Vladimir A.; Mikhailopulo, Igor A.. And the article was included in Synthesis on November 30,2017.Electric Literature of C10H12N4O4  The following contents are mentioned in the article:

Two approaches to the chemoenzymic synthesis of 2-fluorocordycepin and 2-chlorocordycepin were studied: (i) the use of 3′-deoxyadenosine (cordycepin) and 3′-deoxyinosine (3’dIno) as donors of 3-deoxy- D-ribofuranose in the transglycosylation of 2-fluoro- ( 2FAde) and 2-chloroadenine ( 2ClAde) catalyzed by the recombinant E. coli purine nucleoside phosphorylase (PNP), and (ii) the use of 2-fluoroadenosine and 3′-deoxyinosine as substrates of the cross-glycosylation and PNP as a biocatalyst. An efficient method for 3′-deoxyinosine synthesis starting from inosine was developed. However, the very poor solubility of 2ClAde and 2FAde is the limiting factor of the first approach. The second approach enables this problem to be overcome and it appears to be advantageous over the former approach from the viewpoint of practical synthesis of the title nucleosides. The 3-deoxy-α- D-ribofuranose-1-phosphate intermediary formed in the 3’dIno phosphorolysis by PNP was found to be the weak and marginal substrate of E. coli thymidine (TP) and uridine (UP) phosphorylases, resp. Finally, one-pot cascade transformation of 3-deoxy-D-ribose in cordycepin in the presence of adenine and E. coli ribokinase, phosphopentomutase, and PNP was tested and cordycepin formation in ca. 3.4% yield was proved. This study involved multiple reactions and reactants, such as 9-((2R,3R,5S)-3-Hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-ol (cas: 13146-72-0Electric Literature of C10H12N4O4 ).

9-((2R,3R,5S)-3-Hydroxy-5-(hydroxymethyl)tetrahydrofuran-2-yl)-9H-purin-6-ol (cas: 13146-72-0) belongs to tetrahydrofuran derivatives. THF (Tetrahydrofuran) is water-miscible and has a low viscosity making it a highly versatile solvent used in a variety of industries. THF can also be synthesized by catalytic hydrogenation of furan. This allows certain sugars to be converted to THF via acid-catalyzed digestion to furfural and decarbonylation to furan, although this method is not widely practiced.

Impact of Base Analogues within a CpG Dinucleotide on the Binding of DNA by the Methyl-Binding Domain of MeCP2 and Methylation by DNMT1 was written by Lao, Victoria Valinluck; Darwanto, Agus; Sowers, Lawrence C.. And the article was included in Biochemistry on November 30,2010.Name: (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol The following contents are mentioned in the article:

The epigenetic control of transcription requires the selective recognition of methylated CpG dinucleotides by methylation-sensitive sequence-specific DNA binding proteins. In order to probe the mechanism of selective interaction of the methyl-binding protein with methylated DNA, we have prepared a series of oligonucleotides containing modified purines and pyrimidines at the recognition site, and we have examined the binding of these oligonucleotides to the methyl-binding domain (MBD) of the methyl-CpG-binding protein 2 (MeCP2). Our results suggest that pyrimidine 5-substituents similar in size to a Me group facilitate protein binding; however, binding affinity does not correlate with the hydrophobicity of the substituent, and neither the 4-amino group of 5-methylcytosine (mC) nor Watson-Crick base pair geometry is essential for MBD binding. However, 5-substituted uracil analogs in one strand do not direct human DNA methyltransferase 1 (DNMT1) methylation of the opposing strand, as does mC. Important recognition elements do include the guanine O6 and N7 atoms present in the major groove. Unexpectedly, removal of the guanine 2-amino group from the minor groove substantially enhances MBD binding, likely resulting from DNA bending at the substitution site. The enhanced binding of the MBD to oligonucleotides containing several cytosine analogs observed here is better explained by a DNA-protein interface mediated by structured water as opposed to hydrophobic interactions. This study involved multiple reactions and reactants, such as (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol (cas: 550-33-4Name: (2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol).

Separation of nucleotides by hydrophilic interaction chromatography using the FRULIC-N column was written by Padivitage, Nilusha L. T.; Dissanayake, Milan K.; Armstrong, Daniel W.. And the article was included in Analytical and Bioanalytical Chemistry on November 30,2013.Safety of Thymidine 5′-(tetrahydrogen triphosphate) xsodium salt The following contents are mentioned in the article:

A stationary phase composed of silica-bonded cyclofructan 6 (FRULIC-N) was evaluated for the separation of four cyclic nucleotides, six nucleoside monophosphates, four nucleoside diphosphates, and five nucleoside triphosphates via hydrophilic interaction chromatog. (HILIC) in both isocratic and gradient conditions. The gradient conditions gave significantly better separations by narrowing peak widths. Sixteen out of nineteen nucleotides were baseline separated on the FRULIC-N column in one run. Unlike other known HILIC stationary phases, there can be dual-retention mechanisms unique to this media. Traditional hydrogen bonding/dipolar interactions can be supplemented by dynamic ion interaction effects for anionic analytes. This occurs because the FRULIC-N stationary phase is able to bind certain buffer cations. The extent of the ion interaction is tunable, in comparison to stationary phases with embedded charged groups, where the inherent ionic properties are fixed. The best mobile phase conditions were determined by varying the organic modifier (acetonitrile) content, as well as salt type/concentration and electrolyte pH. The thermodn. characteristic of the FRULIC-N column was investigated by evaluating the column temperature effect on retention and utilizing van’t Hoff plots. This study shows that there is a greater entropic contribution for the retention of nucleotide di and triphosphates, whereas there is a greater enthalphic contribution for the cyclic nucleotides with the FRULIC-N column. This study involved multiple reactions and reactants, such as Thymidine 5′-(tetrahydrogen triphosphate) xsodium salt (cas: 18423-43-3Safety of Thymidine 5′-(tetrahydrogen triphosphate) xsodium salt).

Thymidine 5′-(tetrahydrogen triphosphate) xsodium salt (cas: 18423-43-3) belongs to tetrahydrofuran derivatives. Tetrahydrofuran (THF), or oxolane, is mainly used as a precursor to polymers. Being polar and having a wide liquid range, THF is a versatile solvent. Tetrahydrofuran can also be produced, or synthesised, via catalytic hydrogenation of furan. This process involves converting certain sugars into THF by digesting to furfural. An alternative to this method is the catalytic hydrogenation of furan with a nickel catalyst.Safety of Thymidine 5′-(tetrahydrogen triphosphate) xsodium salt

Inhibition of Trypanosoma cruzi growth in mammalian cells by purine and pyrimidine analogs was written by Nakajima-Shimada, Junko; Hirota, Yumiko; Aoki, Takashi. And the article was included in Antimicrobial Agents and Chemotherapy on November 30,1996.Application of 13146-72-0 The following contents are mentioned in the article:

Trypanosoma cruzi, the causative agent of Chagas’ disease, exhibits two different developmental stages in mammals, the amastigote, an intracellular form that proliferates in the cytoplasm of host cells, and the trypomastigote, an extracellular form that circulates in the bloodstream. We have already established an in vitro culture system using mammalian host cells (HeLa) infected with T. cruzi in which the time course of parasite growth is determined quant. We adopted this system for the screening of anti-T. cruzi agents that would ideally prove to be effective trypanosomes with no toxicity to the host cell. Of the purine analogs tested, allopurinol markedly inhibited the growth of amastigotes in a dose-dependent manner, with no lethal effect on trypomastigotes. 3′-Deoxyinosine and 3′-deoxyadenosine also suppressed T. cruzi growth inside the host cell, with the concentrations causing 50% growth inhibition being 10 and 5 μM, resp., in contrast to a concentration causing 50% growth inhibition of 3 μM for allopurinol. Among the pyrimidine analogs examined, 3′-azido-3′-deoxythmidine (zidovudine) significantly reduced the growth of the parasite at concentrations as low as 1 μM. The anti-human immunodeficiency virus agents 2′,3′-dideoxyinosine and 2′,3′-dideoxyadenosine caused a decrease in amastigote growth, while 2′,3′-dideoxycytidine and 2′,3′-dideoxyuridine had no inhibitory effect. When Swiss 3T3 fibroblasts were used as host cells, allopurinol, 3′-deoxyinosine, 3′-deoxyadenosine, and 3′-azido-3′-deoxythymidine also markedly inhibited T. cruzi proliferation. These results indicate that our culture system is useful as a primary screening method for candidate compounds against T. cruzi on the basis of two criteria, namely, intracellular replication by the parasite and host-cell infection rate.

A mild, chemoselective, and generally high-yielding method for the reductive scission of heterocyclic thioethers is described. Suitable heterocycles have a thioether substituent at the 2-position relative to a ring heteroatom. The convenient and straightforward method is demonstrated with reactants which are not compatible with the standard Raney nickel conditions such as sulfides, sulfones, and thiophenes.

Analogs of the glycopeptide antibiotics vancomycin and teichoplanin with alterations in one or both sugar moieties of the disaccharide have been prepared by tandem action of the vancomycin pathway glycosyltransferases GtfE and GtfD. All four regioisomers (2-, 3-, 4-, 6-) of TDP-deoxyglucoses and UDP/TDP-aminoglucoses were prepared, predominantly by action of D-glucopyranosyl-1-phosphate thymidylyltransferase, Ep.

Novel methods for treatment of African trypanosomiasis, caused by infection with Trypanosoma brucei are needed. Cordycepin (3′-deoxyadenosine, 1a) is a powerful trypanocidal compound in vitro but is ineffective in vivo because of rapid metabolic degradation by adenosine deaminase (ADA). The authors elucidated the structural moieties of cordycepin required for trypanocidal activity and designed analogs that retained trypanotoxicity while gaining resistance to ADA-mediated metabolism 2-Fluorocordycepin (2-fluoro-3′-deoxyadenosine) was identified as a selective, potent, and ADA-resistant trypanocidal compound that cured T. brucei infection in mice. 2-Fluorocordycepin is transported through the high affinity TbAT1/P2 adenosine transporter and is a substrate of T. b. brucei adenosine kinase. 2-Fluorocordycepin has good preclin. properties suitable for an oral drug, albeit a relatively short plasma half-life. The authors present a rapid and efficient synthesis of 2-halogenated cordycepins, also useful synthons for the development of addnl. novel C2-substituted 3′-deoxyadenosine analogs to be evaluated in development of exptl. therapeutics.
