Here, we describe detailed synthetic protocols for preparation of 6-amino/thio-2-triazolylpurine ribonucleosides. First, 9-(2′,3′,5′-tri-O-acetyl-β–ribofuranosyl)-2,6-diazido-9H-purine, to be used as a key starting material, is synthesized in an SNAr reaction with NaN3 starting from com. available 9-(2′,3′,5′-tri-O-acetyl-β–ribofuranosyl)-2,6-dichloro-9H-purine. Next, 2,6-bis-triazolylpurine ribonucleoside is obtained in a CuAAC reaction between diazidopurine derivative and Ph acetylene, and used in SNAr reactions with N- and S-nucleophiles. In these reactions, the triazolyl ring at the purine C6 position acts as a good leaving group. Cleavage of acetyl protecting groups from the ribosyl moiety is achieved in presence of piperidine. In the SNAr reaction with amino acid derivatives, the acetyl groups remain intact. Moreover, 9-(2′,3′,5′-tri-O-acetyl-β–ribofuranosyl)-2,6-diazido-9H-purine is selectively reduced at the C6 position using a CuSO4·5H2O/sodium ascorbate system. This provides a straightforward approach for synthesis of 9-(2′,3′,5′-tri-O-acetyl-β–ribofuranosyl)-6-amino-2-azido-9H-purine. 2021 Wiley Periodicals LLC Basic Protocol 1: Synthesis of 6-amino-2-triazolylpurine ribonucleosides Basic Protocol 2: Synthesis of 6-thio-2-triazolylpurine ribonucleosides Basic Protocol 3: Synthesis of 6-amino-2-azidopurine ribonucleoside 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: 550-33-4Synthetic Route of C10H12N4O4  ).

To learn more about the underlying principles of metal ion-mediated recognition of nucleic acid bases, PdCl+ complexes of six 2,6-disubstituted pyridines, viz. pyridine-2,6-dicarboxamide, its N2,N6-dimethyl and N2,N6-diisopropyl derivatives, 6-carbamoylpyridine-2-carboxylic acid, 6-aminomethylpyridine-2-carboxamide and its N2-Me derivative, were prepared and their interaction with nucleoside 5′-monophosphate (NMP) was studied by 1H NMR spectroscopy in D2O at pH 7.2. The binding sites within the nucleobases were assigned on the basis of Pd2 + induced changes in chem. shifts of the base moiety proton resonances. The mole fractions of NMPs engaged in mono- or dinuclear Pd2 + complexes were determined at various concentrations by comparing the intensities of the aromatic and anomeric protons of the complexed and uncomplexed NMPs. Some of the pyridine complexes showed moderate discrimination between the NMPs.

Trypanosomes are purine-auxotrophic parasites that depend upon nucleoside hydrolase (NH) activity to salvage nitrogenous bases necessary for nucleic acid and cofactor synthesis. Nonspecific and purine-specific NHs have been widely studied, yet little is known about the 6-oxopurine-specific isoenzymes, although they are thought to play a primary role in the catabolism of exogenously derived nucleosides. Here, we report the first functional and structural characterization of the inosine-guanosine-specific NH from Trypanosoma brucei brucei. The enzyme shows near diffusion-limited efficiency coupled with a clear specificity for 6-oxopurine nucleosides achieved through a catalytic selection of these substrates. Pre-steady-state kinetic anal. reveals ordered product release, and a rate-limiting structural rearrangement that is associated with the release of the product, ribose. The crystal structure of this trypanosomal NH determined to 2.5 Å resolution reveals distinctive features compared to those of both purine- and pyrimidine-specific isoenzymes in the framework of the conserved and versatile NH fold. Nanomolar iminoribitol-based inhibitors identified in this study represent important lead compounds for the development of novel therapeutic strategies against trypanosomal diseases.

Given a compound, how can we effectively predict its biol. function. It is a fundamentally important problem because the information thus obtained may benefit the understanding of many basic biol. processes and provide useful clues for drug design. In this study, based on the information of chem.-chem. interactions, a novel method was developed that can be used to identify which of the following eleven metabolic pathway classes a query compound may be involved with: (1) Carbohydrate Metabolism, (2) Energy Metabolism, (3) Lipid Metabolism, (4) Nucleotide Metabolism, (5) Amino Acid Metabolism, (6) Metabolism of Other Amino Acids, (7) Glycan Biosynthesis and Metabolism, (8) Metabolism of Cofactors and Vitamins, (9) Metabolism of Terpenoids and Polyketides, (10) Biosynthesis of Other Secondary Metabolites, (11) Xenobiotics Biodegradation and Metabolism It was observed that the overall success rate obtained by the method via the 5-fold cross-validation test on a benchmark dataset consisting of 3,137 compounds was 77.97%, which is much higher than 10.45%, the corresponding success rate obtained by the random guesses. Besides, to deal with the situation that some compounds may be involved with more than one metabolic pathway class, the method presented here is featured by the capacity able to provide a series of potential metabolic pathway classes ranked according to the descending order of their likelihood for each of the query compounds concerned. Furthermore, our method was also applied to predict 5,549 compounds whose metabolic pathway classes are unknown. Interestingly, the results thus obtained are quite consistent with the deductions from the reports by other investigators. It is anticipated that, with the continuous increase of the chem.-chem. interaction data, the current method will be further enhanced in its power and accuracy, so as to become a useful complementary vehicle in annotating uncharacterized compounds for their biol. functions.

Analogs of intermediates involved in the purine salvage pathway can be exploited as potential drug mols. against enzymes of protozoan parasites. To develop such analogs we need knowledge of the solution structures, predominant tautomer at physiol. pH and protonation-state of the corresponding natural ligand. In this regard, we have employed UV resonance Raman spectroscopy (UVRR) in combination with d. functional theory (DFT) to study the solution structures of two relatively unexplored intermediates, 6-phosphoryl IMP (6-pIMP) and succinyl adenosine-5′-monophosphate (sAMP), of purine salvage pathway. These mols. are intermediates in a two step enzymic process that converts inosine-5′-monophosphate (IMP) to adenosine-5′-monophosphate (AMP). Exptl. data on the mol. structure of these ligands is lacking. We report UVRR spectra of these two ligands, obtained at an excitation wavelength of 260 nm. Using isotope induced shifts and DFT calculations we assigned observed spectra to computed normal modes. We find that sAMP exists as neutral species at physiol. pH and the predominant tautomer in solution bears proton at N10 position of purine ring. Though transient in solution, 6-pIMP is captured in the enzyme-bound form. This work provides the structural information of these ligands in solution state at physiol. pH. We further compare these structures with the structures of AMP and IMP. Despite the presence of similar purine rings in AMP and sAMP, their UVRR spectra are found to be very different. Similarly, though the purine ring in 6-pIMP resembles that of IMP, UVRR spectra of the two mols. are distinct. These differences in the vibrational spectra provide direct information on the effects of exocyclic groups on the skeletal structures of these mols. Our results identify key bands in the vibrational spectra of these ligands which may serve as markers of hydrogen bonding interactions upon binding to the active-sites of enzymes.

Carbon nanotubes have displayed great potential in enhancing phytoremediation of PAHs polluted soils. However, the response of plants to the coexistence of carbon nanotubes and PAHs and the associated influencing mechanisms remain largely unknown. Here, the effect of carbon nanotubes on alfalfa growth and pyrene uptake under exposure to pyrene was evaluated through sand culture experiment and gas chromatog. time-of-flight mass spectrometer (GC-TOF-MS) based metabolomics. Results showed that pyrene at 10 mg kg-1 obviously reduced the shoot fresh weight of alfalfa by 18.3%. Multiwall carbon nanotubes (MWCNTs) at 25 and 50 mg kg-1 significantly enhanced the shoot fresh weight in a dose-dependent manner, nearly by 80% at 50 mg kg-1. Pyrene was mainly accumulated in alfalfa roots, in which the concentration was 35 times as much as that in shoots. MWCNTs greatly enhanced the accumulation of pyrene in alfalfa roots, almost by two times at 50 mg kg-1, while decreased pyrene concentration in shoots, from 0.11 mg kg-1 to 0.044 mg kg-1 at MWCNTs concentration of 50 mg kg-1. Metabolomics data revealed that pyrene at 10 mg kg-1 trigged significant metabolic changes in alfalfa root exudates, downregulating 27 metabolites. MWCNTs generated an increase in the contents of some downregulated metabolites caused by pyrene stress, which were restored to the original level or even higher, mainly including organic acids and amino acids. MWNCTs significantly enriched some metabolic pathways pos. correlated with shoot growth and pyrene accumulation in shoots under exposure to pyrene, including TCA cycle, glyoxylate and dicarboxylate metabolism, cysteine and methione metabolism as well as alanine, aspartate and glutamate metabolism This work highlights the regulation effect of MWCNTs on the metabolism of root exudates, which are helpful for alfalfa to alleviate the stress from pyrene contamination.

Lung cancer is the chief reason of cancer death worldwide, and non-small cell lung cancer (NSCLC) make up the majority of lung cancers. Gypenosides are the main active constituents from Gynostemma pentaphyllum. Previous studies showed that they were used to remedy many cancers. The effect of gypenosides on NSCLC has never been studied from the perspective of network pharmacol. and metabolomics. The mechanism is still not clear and remains to be explored. To explore the anti-NSCLC activity and mechanism of gypenosides in A549 cells.Gypenosides of G. pentaphyllum were detected by HPLC-MS. The cytotoxicity was detected by MTT assay. The migration, cell cycle and apoptosis of gypenosides were studied by wound healing assay, JC-1 assay and flow cytometry. The mechanism of gypenosides on NSCLC was studied by metabolomics and network pharmacol. Some key proteins and pathways were further confirmed by Western blot. Eleven gypenosides were detected by HPLC-MS. Gypenosides could suppress the proliferation of A549 cells, inhibit the migration of A549 cells, induce apoptosis and arrest cell cycle in G0/G1 phase. Metabolomics and network pharmacol. approach revealed that gypenosides might affect 17 metabolite related proteins by acting on 9 candidate targets (STAT3, VEGFA, EGFR, MMP9, IL2, TYMS, FGF2, HPSE, LGALS3), thus resulting in the changes of two metabolites (UMP, D-4′-Phosphopantothenate) and two metabolic pathways (pyrimidine metabolism; pantothenate and CoA biosynthesis). Western blotting indicated that gypenosides might inhibit A549 cells through MMP9, STAT3 and TYMS to indirectly affect the pathways of pyrimidine metabolism, pantothenate and CoA biosynthesis. This study revealed that metabolomics combined with network pharmacol. was conducive to understand the anti-NSCLC mechanism of gypenosides.

Nitrogen (N) is an important nutrient for increased potato tuber yield. However, excessive N can decrease tuber quality. Furthermore, the impact of optimal and higher N levels of potato tuber metabolic profile at harvest and cold storage remains unclear. This study aimed to investigate the metabolic profiling of free amino acids and sugars in potato tubers affected by different nitrogen levels (optimal, ON; and excessive, EN) at harvest (AH) and cold storage (CS) (∼4°C, 4 wk) through untargeted GC-TOF-MS, and targeted UHPLC-QqQ-MS. Carbohydrate content and vacuolar invertase activity (IV) were determined Principal component anal. of metabolite data indicated a distinct separation between ON and EN treatments at harvest and cold storage. Multivariate data anal. revealed that sucrose, reducing sugars, and free asparagine were the most altered metabolites (VIP > 1 and P < 0.05), which were involved in starch and sucrose metabolism, and alanine, aspartate and glutamate metabolism At harvest, the absolute contents of various free amino acids including asparagine were higher (by 1.3-1.5 fold) in the EN treatment than ON treatment, and this difference was maintained at 4-wk cold storage. Under the EN treatment, tuber maturity was reduced, and sucrose accumulation was increased at harvest, while IV was increased after cold storage, reducing sugar also accumulated. These results highlighted the neg. effects of EN on free amino acid and sugars metabolism in the post-harvest tubers and provided useful information for understanding the underpinning physiol. mechanisms.

Testing nucleoside analogues as inhibitors of Bacillus anthracis spore germination in vitro and in macrophage cell culture was written by Alvarez, Zadkiel; Lee, Kyungae; Abel-Santos, Ernesto. And the article was included in Antimicrobial Agents and Chemotherapy on December 31,2010.Product Details of 550-33-4 The following contents are mentioned in the article:

Bacillus anthracis, the etiol. agent of anthrax, has a dormant stage in its life cycle known as the endospore. When conditions become favorable, spores germinate and transform into vegetative bacteria. In inhalational anthrax, the most fatal manifestation of the disease, spores enter the organism through the respiratory tract and germinate in phagosomes of alveolar macrophages. Germinated cells can then produce toxins and establish infection. Thus, germination is a crucial step for the initiation of pathogenesis. B. anthracis spore germination is activated by a wide variety of amino acids and purine nucleosides. Inosine and L-alanine are the two most potent nutrient germinants in vitro. Recent studies have shown that germination can be hindered by isomers or structural analogs of germinants. 6-Thioguanosine (6-TG), a guanosine analog, is able to inhibit germination and prevent B. anthracis toxin-mediated necrosis in murine macrophages. In this study, we screened 46 different nucleoside analogs as activators or inhibitors of B. anthracis spore germination in vitro. These compounds were also tested for their ability to protect the macrophage cell line J774a.1 from B. anthracis cytotoxicity. Structure-activity relationship anal. of activators and inhibitors clarified the binding mechanisms of nucleosides to B. anthracis spores. In contrast, no structure-activity relationships were apparent for compounds that protected macrophages from B. anthracis-mediated killing. However, multiple inhibitors additively protected macrophages from B. anthracis.
