A tandem enzymic strategy to enhance the scope of C-alkylation of small mols. via the in situ formation of S-adenosyl methionine (SAM) cofactor analogs is described. A solvent-exposed channel present in the SAM-forming enzyme SalL tolerates 5′-chloro-5′-deoxyadenosine (ClDA) analogs modified at the 2-position of the adenine nucleobase. Coupling SalL-catalyzed cofactor production with C-(m)ethyl transfer to coumarin substrates catalyzed by the methyltransferase (MTase) NovO forms C-(m)ethylated coumarins in superior yield and greater substrate scope relative to that obtained using cofactors lacking nucleobase modifications. Establishing the mol. determinants that influence C-alkylation provides the basis to develop a late-stage enzymic platform for the preparation of high value small mols.

In plants, 3′,5′-cyclic adenosine monophosphate (cAMP) is an important second messenger with varied functions; however, only a few adenylyl cyclases (ACs) that synthesize cAMP have been identified. Moreover, the biol. roles of ACs/cAMP in response to stress remain largely unclear. In this study, we used quant. proteomics techniques to identify a maize heat-induced putative disease-resistance RPP13-like protein 3 (ZmRPP13-LK3), which has three conserved catalytic AC centers. The AC activity of ZmRPP13-LK3 was confirmed by in vitro enzyme activity anal., in vivo RNAi experiments, and functional complementation in the E. coli cyaA mutant. ZmRPP13-LK3 is located in the mitochondria. The results of in vitro and in vivo experiments indicated that ZmRPP13-LK3 interacts with ZmABC2, a possible cAMP exporter. Under heat stress, the concentrations of ZmRPP13-LK3 and cAMP in the ABA-deficient mutant vp5 were significantly less than those in the wild-type, and treatment with ABA and an ABA inhibitor affected ZmRPP13-LK3 expression in the wild-type. Application of 8-Br-cAMP, a cAMP analog, increased heat-induced expression of heat-shock proteins in wild-type plants and alleviated heat-activated oxidative stress. Taken together, our results indicate that ZmRPP13-LK3, a new AC, can catalyze ATP for the production of cAMP and may be involved in ABA-regulated heat resistance.

A unique series of simple “unnatural” nucleosides has been discovered to inhibit hepatitis B virus (HBV) replication. Through structure-activity anal. it was found that the 3′-OH group of the β-L-2′-deoxyribose of the β-L-2′-deoxynucleoside confers specific antihepadnavirus activity. The unsubstituted nucleosides β-L-2′-deoxycytidine, β-L-thymidine, and β-L-2′-deoxyadenosine had the most potent, selective, and specific antiviral activity against HBV replication. Human DNA polymerases (α, β, and γ) and mitochondrial function were not affected. In the woodchuck model of chronic HBV infection, viral load was reduced by as much as 108 genome equivalent/mL of serum and there was no drug-related toxicity. In addition, the decline in woodchuck hepatitis virus surface antigen paralleled the decrease in viral load. These investigational drugs, used alone or in combination, are expected to offer new therapeutic options for patients with chronic HBV infection.

Oudemansiella raphanipes (O. raphanipes) has recently been gaining popularity due to its active and flavor compounds In this study, the profiles of phenolics, flavonoids, non-volatile and volatile compounds of fresh O. raphanipes were subjected to cutting root (CR) and pulling root (PR) harvesting methods during different storage temperatures (5°C and 20°C) were investigated. The results showed that CR treatment effectively increased phenolic and flavonoid contents, maintained the sensory scores and the umami value based on e-tongue, increased more C8 volatile contents, and inhibited off-flavor acids production during 5°C storage. The EUC values of the fresh O. raphanipes ranged from 4.72 to 23.66 g monosodium glutamate (MSG) 100 g-1, which TAVs were at a relatively high level in CR treatment than in PR treatment. A two-way anal. of variance (ANOVA) and principal component anal. (PCA) revealed statistically significant differences in different harvesting methods that affected the mushroom flavor. Eleven components were screened as taste characteristics contributors by partial least squares regression model (PLS-R) anal., including Glu, umami nucleotides, and 1-octene-3-ol and 3-octanone. Thus, the cutting root treatment is a promising method for obtaining the high flavor quality of fresh O. raphanipes during cooling storage.

Structural transformation of the canonical right-handed helix, B-DNA, to the non-canonical left-handed helix, Z-DNA, can be induced by the Zα domain of the human RNA editing enzyme ADAR1 (hZαADAR1). To characterize the site-specific preferences of binding and structural changes in DNA containing the 2′-O-Me guanosine derivative (mG), titration of the imino proton spectra and chem. shift perturbations were performed on hZαADAR1 upon binding to Z-DNA. The structural transition between B-Z conformation as the changing ratio between DNA and protein showed a binding affinity of the modified DNA onto the Z-DNA binding protein similar to wild-type DNA or RNA. The chem. shift perturbation results showed that the overall structure and environment of the modified DNA revealed DNA-like properties rather than RNA-like characteristics. Moreover, we found evidence for two distinct regimes, “Z-DNA Sensing” and “Modification Sensing”, based on the site-specific chem. shift perturbation between the DNA (or RNA) binding complex and the modified DNA-hZαADAR1 complex. Thus, we propose that modification of the sugar backbone of DNA with 2′-O-Me guanosine promotes the changes in the surrounding α3 helical structural segment as well as the non-perturbed feature of the β-hairpin region.

Pd(0)/Cu(I)-Mediated Direct Arylation of 2′-Deoxyadenosines: Mechanistic Role of Cu(I) and Reactivity Comparisons with Related Purine Nucleosides was written by Storr, Thomas E.;Baumann, Christoph G.;Thatcher, Robert J.;De Ornellas, Sara;Whitwood, Adrian C.;Fairlamb, Ian J. S.. And the article was included in Journal of Organic Chemistry in 2009.Application In Synthesis of (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-(hydroxymethyl)tetrahydrofuran-3-ol hydrate This article mentions the following:

Pd/Cu-mediated direct arylation of 2′-deoxyadenosine with various aryl iodides provides 8-arylated 2′-deoxyadenosine derivatives in good yields. Following significant reaction optimization, it has been determined that a substoichiometric quantity of piperidine (secondary amine) in combination with cesium carbonate is necessary for effective direct arylation. The general synthetic protocol allows lower temperature direct arylations, which minimizes deglycosylation. The origin of the piperidine effect primarily derives from the in situ generation of Pd(OAc)2[(CH2)5NH]2. Various copper(I) salts have been evaluated; only CuI provides good yields of the 8-arylated-2′-deoxyadenosines. Copper(I) appears to have a high binding affinity for 2′-deoxyadenosine, which explains the mandatory requirement for stoichiometric amounts of this key component. The conditions are compared with more general direct arylation protocols, e.g., catalytic Pd, ligand, acid additives, which do not employ copper(I). In each case, no detectable arylation of 2′-deoxyadenosine was noted. The conformational preferences of the 8-aryl-2′-deoxyadenosine products have been determined by detailed spectroscopic (NMR) and single crystal X-ray diffraction studies. Almost exclusively, the preferred solution-state conformation was determined to be syn-C2′-endo (ca. 80%). The presence of a 2-pyridyl group at the 8-position further biases the solution-state equilibrium toward this conformer (ca. 88%), due to an addnl. H-bond between H1′ and the pyridyl nitrogen atom. The Pd/Cu catalyst system has been found to be unique for adenosine type substrates, the reactivity of which has been placed into context with the reported direct arylations of related 1H-imidazoles. The reactivity of other purine nucleosides has been assessed, which has revealed that both 2′-deoxyguanosine and guanosine are incompatible with the Pd/Cu-direct arylation conditions. Both substrates appear to hinder catalysis, akin to the established inhibitory effects in Suzuki cross-couplings with arylboronic acids. In the experiment, the researchers used many compounds, for example, (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-(hydroxymethyl)tetrahydrofuran-3-ol hydrate (cas: 16373-93-6Application In Synthesis of (2R,3S,5R)-5-(6-Amino-9H-purin-9-yl)-2-(hydroxymethyl)tetrahydrofuran-3-ol hydrate).

Exploring the intracellular pharmacokinetics of the 5-fluorouracil nucleotides during capecitabine treatment was written by Derissen, Ellen J. B.;Jacobs, Bart A. W.;Huitema, Alwin D. R.;Rosing, Hilde;Schellens, Jan H. M.;Beijnen, Jos H.. And the article was included in British Journal of Clinical Pharmacology in 2016.Formula: C9H11FN2O5 This article mentions the following:

Aim : Three intracellularly formed metabolites are responsible for the antineoplastic effect of capecitabine: 5-fluorouridine 5′-triphosphate (FUTP), 5-fluoro-2′-deoxyuridine 5′-triphosphate (FdUTP), and 5-fluoro-2′-deoxyuridine 5′-monophosphate (FdUMP). The objective of this study was to explore the pharmacokinetics of these intracellular metabolites during capecitabine treatment. Methods : Serial plasma and peripheral blood mononuclear cell (PBMC) samples were collected from 13 patients treated with capecitabine 1000 mg QD (group A) and eight patients receiving capecitabine 850 mg m-2 BID for fourteen days, every three weeks (group B). Samples were collected on day 1 and, for four patients of group B, also on day 14. The capecitabine and 5-fluorouracil (5-FU) plasma concentrations and intracellular metabolite concentrations were determined using LC-MS/MS. Pharmacokinetic parameters were estimated using non-compartmental anal. Results : Only FUTP could be measured in the PBMC samples. The FdUTP and FdUMP concentrations were below the detection limits (LOD). No significant correlation was found between the plasma 5-FU and intracellular FUTP exposure. The FUTP concentration-time profiles demonstrated considerable inter-individual variation and accumulation of the metabolite in PBMCs. FUTP levels ranged between <LOD and 1.0 μM on day 1, and from 0.64 to 14 μM on day 14. The area under the FUTP concentration-time curve was significantly increased on day 14 of the treatment compared to day 1 (mean ± SD: 28 ± 19 μM h vs. 2.0 ± 1.9 μM h). Conclusions : To our knowledge, this is the first time that intracellular FUTP concentrations were measured in patients treated with capecitabine. During 14 days of treatment with capecitabine twice daily, intracellular accumulation of FUTP occurs. In the experiment, the researchers used many compounds, for example, 1-((2R,3R,4S,5R)-3,4-Dihydroxy-5-methyltetrahydrofuran-2-yl)-5-fluoropyrimidine-2,4(1H,3H)-dione (cas: 3094-09-5Formula: C9H11FN2O5).
