Nucleotide analog interference mapping (NAIM) is a quick and efficient method to define concurrently, yet singly, the importance of specific functional groups at particular nucleotide residues to the structure and function of an RNA. NAIM can be utilized on virtually any RNA with an assayable function. The method hinges on the ability to successfully incorporate, within an RNA transcript, various 5′-O-(1-thio)nucleoside analogs randomly via in vitro transcription. This could be achieved by using wild-type or Y639F mutant T7 RNA polymerase, thereby creating a pool of analog doped RNAs. The pool when subjected to a selection step to sep. the active transcripts from the inactive ones leads to the identification of functional groups that are crucial for RNA activity. The technique can be used to study ribozyme structure and function via monitoring of cleavage or ligation reactions, define functional groups critical for RNA folding, RNA-RNA interactions, and RNA interactions with proteins, metals, or other small mols. All major classes of catalytic RNAs have been probed by NAIM. This is a generalized approach that should provide the scientific community with the tools to better understand RNA structure-activity relationships. 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: 550-33-4Related Products of 550-33-4).

(2R,3S,4R,5R)-2-(Hydroxymethyl)-5-(9H-purin-9-yl)tetrahydrofuran-3,4-diol (cas: 550-33-4) belongs to tetrahydrofuran derivatives. Solid acid catalysis, and the advantages often associated with their use, have been proved equally efficient for the synthesis of tetrahydrofurans or furans.

RNA modifications play an important role in the regulation of gene expression and the development of RNA-based therapeutics, but their identification, localization and relative quantitation by conventional biochem. methods can be quite challenging. As a promising alternative, mass spectrometry (MS) based approaches that involve RNA dissociation in ‘top-down’ strategies are currently being developed. For this purpose, it is essential to understand the dissociation mechanisms of unmodified and posttranscriptionally or synthetically modified RNA. Here, we have studied the effect of select nucleobase, ribose and backbone modifications on phosphodiester bond cleavage in collisionally activated dissociation (CAD) of pos. and neg. charged RNA. We found that CAD of RNA is a stepwise reaction that is facilitated by, but does not require, the presence of pos. charge. Preferred backbone cleavage next to adenosine and guanosine in CAD of (M + nH)n+ and (M-nH)n- ions, resp., is based on hydrogen bonding between nucleobase and phosphodiester moieties. Moreover, CAD of RNA involves an intermediate that is sufficiently stable to survive extension of the RNA structure and intramol. proton redistribution according to simple Coulombic repulsion prior to backbone cleavage into c and y ions from phosphodiester bond cleavage.

Toxoplasma gondii is unable to synthesize purines de novo, instead salvages them from its environment, inside the host cell, for which they need high affinity carriers. Here, we report the expression of a T. gondii Equilibrative Nucleoside Transporter, Tg244440, in a Trypanosoma brucei strain from which nucleobase transporters have been deleted. Tg244440 transported hypoxanthine and guanine with similar affinity (Km ∼1 μM), while inosine and guanosine displayed Ki values of 4.05 and 3.30 μM, resp. Low affinity was observed for adenosine, adenine, and pyrimidines, classifying Tg244440 as a high affinity oxopurine transporter. Purine analogs were used to probe the substrate-transporter binding interactions, culminating in quant. models showing different binding modes for oxopurine bases, oxopurine nucleosides, and adenosine. Hypoxanthine and guanine interacted through protonated N1 and N9, and through unprotonated N3 and N7 of the purine ring, whereas inosine and guanosine mostly employed the ribose hydroxy groups for binding, in addition to N1H of the nucleobase. Conversely, the ribose moiety of adenosine barely made any contribution to binding. Tg244440 is the first gene identified to encode a high affinity oxopurine transporter in T. gondii and, to the best of our knowledge, the first purine transporter to employ different binding modes for nucleosides and nucleobases.

Blue and green molds, the common phenotypes of post-harvest diseases in fruits, are mainly caused by Penicillium fungal species, including P. italicum, P. digitatum, and P. expansum. We sequenced and assembled the genome of a P. italicum strain, which contains 31,034,623 bp with 361 scaffolds and 627 contigs. A dual-transcriptome anal. following the infection of Valencia orange (Citrus sinensis) by P. italicum resulted in the annotation of 9,307 P. italicum genes and 24,591 Valencia orange genes. The pathogenicity of P. italicum may be due to the activation of effectors, including 51 small secreted cysteine-rich proteins, 110 carbohydrate-active enzymes, and 12 G protein-coupled receptors. Addnl., 211 metabolites related to the interactions between P. italicum and Valencia orange were identified by gas chromatog.-time of flight mass spectrog., three of which were further confirmed by ultra-high performance liquid chromatog. triple quadrupole mass spectrometry. Moreover, a correlation anal. between the metabolite contents and gene expression levels suggested that P. italicum induces carbohydrate metabolism in Valencia orange fruits as part of its infection strategy. This study provides useful information regarding the genomic determinants that drive the evolution of host specificity in Penicillium species and clarifies the host-plant specificity during the infection of Valencia orange by P. italicum.

This study aimed to determine the effects of an early-life lactoferrin (LF) intervention on liver metabolism in suckling piglets. Sixty newborn piglets with an average initial body weight (BW) of 1.51 ± 0.05 kg were assigned to a control (CON) group and an LF group. At age 1 to 7 days, the piglets in the LF group were orally administered LF solution (0.5 g per kg BW daily), whereas the piglets in the CON group were orally administered the same dose of physiol. saline. Plasma, jejunum and liver samples were collected on days 8 and 21. The LF piglets showed a decreased plasma urea nitrogen level on day 8 and an increased plasma albumin level on day 21. Pathway anal. of the metabolomic profiles showed that the LF treatment affected amino acid metabolism in the liver. In addition, the LF treatment upregulated the gene expression levels of proteolytic enzymes and amino acid transporters (APA, APN, EAAC1, Pept1, CAT1, B0AT1 and ASCT2) in the jejunum, and it enhanced the phosphorylation levels of mTOR and p70S6K in the liver. The LF treatment also upregulated the expression of a β-oxidation-related gene (CPT1) and affected the tricarboxylic acid cycle in the liver on day 21. Furthermore, the LF piglets showed a decreased level of malondialdehyde and increased levels of GSH, GSH-Px and GCLC in the liver mitochondria. Overall, the early-life LF intervention affected the protein synthesis, energy production and antioxidative capacity in the liver of the neonatal piglets.

Cellular and virus-coded long non-coding (lnc) RNAs support multiple roles related to biol. and pathol. processes. Several lncRNAs sequester their 3 termini to evade cellular degradation machinery, thereby supporting disease progression. An intramol. triplex involving the lncRNA 3 terminus, the element for nuclear expression (ENE), stabilizes RNA transcripts and promotes persistent function. Therefore, such ENE triplexes, as presented here in Kaposi′s sarcoma-associated herpesvirus (KSHV) polyadenylated nuclear (PAN) lncRNA, represent targets for therapeutic development. Towards identifying novel ligands targeting the PAN ENE triplex, we screened a library of immobilized small mols. and identified several triplex-binding chemotypes, the tightest of which exhibits micromolar binding affinity. Combined biophys., biochem., and computational strategies localized ligand binding to a platform created near a dinucleotide bulge at the base of the triplex. Crystal structures of apo (3.3 Å) and ligand-soaked (2.5 Å) ENE triplexes, which include a stabilizing basal duplex, indicate significant local structural rearrangements within this dinucleotide bulge. MD simulations and a modified nucleoside analog interference technique corroborate the role of the bulge and the base of the triplex in ligand binding. Together with recently discovered small mols. that reduce nuclear MALAT1 lncRNA levels by engaging its ENE triplex, our data supports the potential of targeting RNA triplexes with small mols.

A radiochemical high-performance liquid chromatographic method for the analysis of 2-fluoro-2-deoxy-D-glucose-derived metabolites in human chondrocytes was written by Fedders, Goenna; Kock, Ruediger; Van de Leur, Eddy; Greiling, Helmut. And the article was included in Analytical Biochemistry in 1993.Reference of 67341-43-9 The following contents are mentioned in the article:

A HPLC method with online radioactivity monitoring was developed for the measurement of 2-fluoro-2-deoxy-D-[U-14C]-glucose-derived metabolites in a cell culture system of human chondrocytes embedded in soft agarose. To optimize the chromatog. procedure, glucose-analog substrates derived from 2-fluoro-2-deoxy-D-glucose (I) by enzymic synthesis in vitro were used. The synthesized metabolites were separated by anion-exchange chromatog. on a Partisil 10 SAX cartridge with a LiChrosorb RP 18-5 guard column eluted with a 35-min ion-strength/pH gradient performed from 15 mM NH4H2PO4, pH 3.8, to 0.75 M NH4H2PO4, pH 4.8, at a flow rate of 2 mL/min. Only by using an online radioactivity monitor instead of an off-line counting procedure was the resolution obtained sufficient for the determination of these intermediates. This method was applied to studying the metabolic pathway of I in human chondrocytes. Due to the resistance of the chondrocytes embedded in soft agarose, the usual cell-lysing methods could not be used; therefore, an extraction procedure for acid-stable glucose metabolites, which may also be applied to other resistant cell lines or critical cell culture systems, was developed. With the procedure presented here, the existence of metabolites of I resulting from enzymic reactions following the hexokinase reaction was proven. Evidence is presented here for the first time that chondrocytes are able to metabolize I to the UDP-activated sugars, UDP-2-fluoro-2-deoxy-D-glucose, UDP-2-fluoro-2-deoxy-D-galactose, and UDP-2-fluoro-2-deoxy-D-glucuronic acid.

Antileukemic activity and mechanism of action of cordycepin against terminal deoxynucleotidyl transferase-positive (TdT+) leukemic cells was written by Kodama, E. N.; McCaffrey, R.

The nucleoside analog cordycepin (3′-deoxyadenosine, 3′-dA) is substantially more cytotoxic to terminal deoxynucleotidyl transferase pos. (TdT+) leukemic cells than to TdT- leukemic cells in vitro in the presence of an adenosine deaminase inhibitor, deoxycoformycin (dCF), and has been considered as a therapeutic agent for TdT+ leukemia. The intracellular metabolism of 3′-dA was examined with HPLC, and the mechanism of its anti-TdT+ leukemic activity was analyzed. In the presence of dCF (2.5 μM), TdT+ leukemic cells (N = 5) were sensitive to the cytotoxic effect of 3′-dA, whereas TdT- (N = 6) cells were not. A high level of 3′-dA-5′-triphosphate (3′-dATP) formation was detected in TdT+ NALM-6 cells (67 pmol/106 cells) and TdT- K562 cells (49 pmol/106 cells) when cultured with 1 μM [3′-3H]-labeled 3′-dA. A substantial level of 3′-dATP was detected in TdT- HUT-102 cells (27 pmol/106 cells), whereas the level of 3′-dATP in TdT+ MOLT-4 cells was low (0.3 pmol/106 cells). The mean IC50 values of 3′-dA against phytohemagglutinin (PHA)-activated and resting peripheral blood mononuclear cells (PBM) (N = 5) were 8 and 32 μM, resp. There was a modest level of 3′-dATP (7 pmol/106 cells) in PHA-PBM, whereas a lower level of 3′-dATP was detected in resting PBM (2.5 pmol/106 cells). These data suggest that the presence of 3′-dATP is not sufficient for the antileukemic effect of 3′-dA, but that TdT positivity is essential, and that PBM are significantly less sensitive to the cytotoxicity of 3′-dA in vitro. Further development of 3′-dA as a potential antileukemic agent to treat patients with TdT+ leukemia is warranted.

To have in depth knowledge about the effects of nonselective and selective inhibitory and activated agents on adenylyl cyclase in rat kidney. A variety of concentrations of pharmacol. agents were prepared They include nebularine, Ap3A, forskolin, Ap4A and caffeine. Furthermore, effects of these agents were noted in relation to rat kidney adenylyl activity. Tissue of rat kidney was used in the process of preparation of crude extract Activity of adenylyl cyclase in connection with crude extract was observed [2-H3] ATP was used as substrate which ultimately lead to the formation of cAMP. Pharmacol. agents with their prepared concentrations were tested. Prominent activator of adenylyl cyclase, forskolin, was selected as a compound Ap4A, caffeine, nebularine, and Ap3A were utilized for comparison purpose. Adenylyl cyclase activity was at peak at 100 M forskolin as per concluded results. Nebularine inhibited activity of enzyme when agent concentration enhanced up to 50 M where the inhibition started to stable. No considerable effect on the enzyme activity in kidney tissue was observed when caffeine with 10 – 300 M on the of adenylyl cyclase activity was used. No effect on adenylyl cyclase activity was noted when Ap3A over the concentration range of 10 – 300 M was used. However, an inhibition effect on the enzyme activity was noted when Ap4A with the concentration 100 M was used. Role of cyclic nucleotides in metabolism control and cell-signaling is undeniably significant. It stimulates inhibitors and activities of cyclase to make some likely physiol. impacts. Foreskin being initiator of adenylyl cyclase, Ap4A and nebularine are established to be latent inhibitors of cyclase, which signifies their importance in curing schizophrenia, mania, seizure, etc. 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: 550-33-4Related Products of 550-33-4).
