Vibrio cholerae faces nitrosative stress during successful colonization in intestine. Very little information is available on the nitrosative stress protective mechanisms of V. cholerae. Reports show that NorR regulon control two genes hmpA and nnrS responsible for nitric oxide (NO) detoxification in V. cholerae. In the present study we first time report a novel role of V. cholerae catalases under nitrosative stress. Using zymogram analysis of catalase we showed that KatB and KatG activity were induced within 30 min in V. cholerae in the presence of sodium nitroprusside (SNP), a NO donor compound. Surprisingly, V. cholerae cell survival was found to be decreased under nitrosative stress if catalase activities were blocked by ATz, a catalase inhibitor. Flow cytometry study was conducted to detect reactive oxygen species (ROS) and reactive nitrogen species (RNS) using DHE and DHR123, fluorescent probes respectively. Short exposure of SNP to V. cholerae did not generate ROS but RNS was detectable within 30 min. Total glutathione content was increased in V. cholerae cells under nitrosative stress. Furthermore, Superoxide dismutase (SOD) and Glutathione reductase (GR) activities remained unchanged under nitrosative stress in V. cholerae indicated antioxidant role of NO which could produce peroxynitrite. To investigate the role of catalase induction under nitrosative stress in V. cholerae, we conducted peroxynitrite reductase assay using cell lysates. Interestingly, SNP treated V. cholerae cell lysates showed lowest DHR123 oxidation compared to the control set. The extent of DHR123 oxidation was more in V. cholerae cell lysate when catalases were blocked by ATz.

Under both conventional and microwave methods, 2-amino-4H-pyran-3-carbonitrile derivative 1 was synthesized and reacted with different reagents. Thus, 2-amino-4H-pyran-3-carbonitrile derivative was treated with chloroacetyl chloride, phenyl isocyanate, cyanoacetic acid, benzoyl chloride, triethyl orthoformate, acetic anhydride/H2SO4, arylidene malononitrile, urea, and/or p-aminosulphaguanidine producing chloroacetamide, 3-phenylurea, cyanoacetamide, N-benzoylpyran, ethylformimidate, pyranopyrimidin-4-one, pyranopyridine, pyranopyrimidin-2-one, and pyranopyrimidin-2-imine derivatives, respectively. Meanwhile, compound 1 was reacted with ethyl bromoacetate, phenacyl bromide, phthalic anhydride, different aromatic amines, and/or acetic acid/H2SO4 to produce 5-aminopyrano[2,3-b]pyrrole-6-carboxylate, dihydropyrano[2,3-b]pyrrole-6-yl-(phenyl)methanone, 1,3-dioxoisoindolinyl pyran, 1,4-dihydropyridine, and 2-hydroxy-1,4-dihydropyridine derivatives, respectively. On the other hand, when compound 1 was allowed to react with maleic anhydride and/or hydrazine hydrate, pyran-4-oxobut-2-enoic acid and 3-aminopyranopyrazole derivatives were obtained, respectively. Reaction of pyran-4-oxobut-2-enoic acid with malononitrile under different conditions gave 2-(furan-2-yl)-4H-pyran and 2-(4H-pyran-2-yl)-1H-pyrrole derivatives, while condensation of 3-aminopyranopyrazole with benzaldehyde gave 1,4-dihydropyrano[2,3-c]pyrazol-3-yl-1-phenylmethanimine derivative. The newly synthesized compounds were characterized by the spectroscopic tools IR, H-1-NMR, C-13-NMR, MS, and elemental analysis. Some of these compounds have been screened in vitro for antimicrobial activity against different strains of bacteria and fungi and also were tested against two cancer cell lines: mammary gland breast cancer (MCF-7) and colon cancer (HCT-118).

Cobalt oxide (Co3O4) nanoparticles decorated on mesoporous carbon nitride (Co3O4/MCN) nanocomposites for photocatalytic hydrogen evolution were investigated in this work. MCN was prepared using 3-amino-1,2,4-triazole, high nitrogen content, as a single molecular carbon and nitrogen precursor and SiO2 nanoparticles as the hard template. Complementary characterization techniques were employed to understand the textural and chemical properties of the nanocomposites. The bare MCN showed high photocatalytic activity under visible light irradiation without using any co-catalyst. The photocatalytic activity of Co3O4/MCN with a Co3O4 mass content of 5 wt % presented two times higher than the bare MCN, which is attributed to the enhanced visible-light harvesting and more efficient charge separation. Mechanistic study shows lower electron-hole recombination rate, higher charge separation efficiency occurs after the formation of p-n type heterojunction. (C) 2019 Hydrogen Energy Publications LLC.

Herein, Fe3O4 nano-particles are anchored over nitrogen doped reduced graphene oxide Fe3O4@N-rGO) structure to accommodate electric and magnetic components, so that it could match both the conduction and polarization loss to augment the attenuation of electromagnetic radiation. The formation of condensed heteroaromatic structure and decoration of Fe3O4 particles on r-GO structure are confirmed by photoelectron spectroscopy (XPS). high-resolution transmission electron microscopy (HRTEM), X-ray diffraction (XRD). The Fe3O4@N-rGO hybrid is subsequently dispersed in epoxy matrix, which result in significantly higher electrical conductivity (1.31 s/m) and electromagnetic interference (EMI) shielding efficiency (- 26 dB at 1 mm thickness). It was assumed that presence of electric-magnetic integrated Fe3O4@N-rGO hybrid in epoxy matrix significantly improved the interfacial polarization and anisotropy energy, which was reflected in absorption loss value of -27 dB. The composites also exhibited enhanced mechanical and thermo-mechanical properties coupled with improved thermal stability.

In plants, light-dependent activation of de novo fatty acid synthesis (FAS) is partially mediated by acetyl-CoA carboxylase (ACCase), the first committed step for this pathway. However, it is not fully understood how plants control light-dependent FAS regulation to meet the cellular demand for acyl chains. We report here the identification of a gene family encoding for three small plastidial proteins of the envelope membrane that interact with the alpha-carboxyltransferase (alpha-CT) subunit of ACCase and participate in an original mechanism restraining FAS in the light. Light enhances the interaction between carboxyltransferase interactors (CTIs) and alpha-CT, which in turn attenuates carbon flux into FAS. Knockouts for CTI exhibit higher rates of FAS and marked increase in absolute triacylglycerol levels in leaves, more than 4-fold higher than in wild-type plants. Furthermore, WRINKLED1, a master transcriptional regulator of FAS, positively regulates CTI1 expression by direct binding to its promoter. This study reveals that in addition to light-dependent activation, envelope docking of ACCase permits fine-tuning of fatty acid supply during the plant life cycle.

In the title molecule, C13H16N4O3, the mean planes of the phenyl and triazole rings are nearly perpendicular to one another as a result of the intramolecular C-H center dot center dot center dot O and C-H center dot center dot center dot pi(ring) interactions. In the crystal, layers parallel to (101) are generated by O-H center dot center dot center dot N, N-H center dot center dot center dot O and N-H center dot center dot center dot N hydrogen bonds. The layers are connected by inversion-related pairs of C-H center dot center dot center dot O hydrogen bonds. The experimental molecular structure is close to the gas-phase geometryoptimized structure calculated by DFT methods. Hirshfeld surface analysis indicates that the most important interaction involving hydrogen in the title compound is the H center dot center dot center dot H contact. The contribution of the H center dot center dot center dot O, H center dot center dot center dot N, and H center dot center dot center dot H contacts are 13.6, 16.1, and 54.6%, respectively.

Glutamine plays a critical role in ammonium assimilation, and contributes substantially to the taste and nutritional quality of tea. To date, little research has been done on glutamine synthesis in tea plants. Here, a zinc finger protein CsDOF and a glutamine synthetase (GS)-encoding gene CsGS2 from tea plant (Camellia sinensis cv ‘Shuchazao’) were characterized, and their role in glutamine biosynthesis was determined using transient suppression assays in tea leaves and overexpression in Arabidopsis thaliana. The expression patterns of CsDOF and CsGS2, the GS activity and the glutamine content of photosynthetic tissues (leaf and bud) were significantly induced by shade. Suppressing the expression of CsDOF resulted in downregulated expression of CsGS2 and reduction of the leaf glutamine content. Moreover, in CsDOF-silenced plants, the expression of CsDOF and the glutamine content under shade treatment were higher than in natural light. The glutamine content and CsGS2 transcript level were also decreased in tea leaves when CsGS2 was suppressed, while they were higher under shade treatment than in natural light in CsGS2-silenced plants. In addition, the glutamine content and GS2 transcript level were increased when CsDOF and CsGS2 was overexpressed in Arabidopsis thaliana, respectively. In binding analyses, CsDOF directly bound to an AAAG motif in the promoter of CsGS2, and promotes its activity. The study shed new light on the molecular mechanism by which CsDOF activates CsGS2 gene expression and contributes to glutamine biosynthesis in tea plants.

Annulated C-beta-D-glucopyranosyl heterocycles were synthesized and tested as inhibitors of glycogen phosphorylase. 2-(beta-D-Glucopyranosyl)-1H-imidazo[4,5-b] pyridine was formed by ring-closure of O-perbenzoylated C-beta-D-glucopyranosyl formic acid with 2,3-diaminopyridine in the presence of triphenylphosphite. Cyclisations of bromomethyl 2,3,4,6-tetra-O-benzoyl-beta-D-glucopyranosyl ketone with a set of 2-aminoheterocycles resulted in constitutionally reversed C-beta-D-glucopyranosyl imidazoles fused by pyridine, pyrimidine, thiazole, 1,3,4-thiadiazole, benzothiazole and benzimidazole. O-Debenzoylation of the above compounds was effected by standard transesterification to get the test compounds. The 1H-imidazo[4,5-b] pyridine proved to be a low micromolar inhibitor (K-i = 21.1 mu M) of rabbit muscle glycogen phosphorylase b, while the other heterocycles displayed weak or no inhibition against the same enzyme.

I found the field of Plant Sciences very interesting. Saw the article Cytochrome P450 metabolism-based herbicide resistance to imazamox and 2,4-D in Papaver rhoeas published in 2021.0. Formula: C2H4N4, Reprint Addresses Torra, J (corresponding author), Univ Lleida, Dept Hortofructicultura Bot & Jardineria, Agrotecnio, Alcalde Rovira Roure 191, Lleida 25198, Spain..

Papaver rhoeas biotypes displaying multiple herbicide resistance to ALS inhibitors and synthetic auxin herbicides (SAH) are spreading across Europe. In Spain, enhanced metabolism to imazamox was confirmed in one population, while cytochrome-P450 (P450) based metabolism to 2,4-D in another two. The objectives of this research were to further confirm the presence of P450 mediated enhanced metabolism and, if so, to confirm whether a putative common P450 is responsible of metabolizing both 2,4-D and imazamox. Metabolism studies were undertaken in five P. rhoeas populations with contrasted HR profiles (herbicide susceptible, only HR to ALS inhibitors, only HR to SAH, or multiple HR to both), and moreover, three different P450 inhibitors were used. The presence of enhanced metabolism to these SoA was confirmed in three more HR P. rhoeas populations. This study provides the first direct evidence that imazamox metabolism in these biotypes is P450-mediated, also in one population without an altered target site. Additionally, it was further confirmed that enhanced metabolism of 2,4-D in biotypes only HR to SAH or multiple HR to ALS inhibitors and SAH involves P450 as well. No metabolism was detected using the three inhibitors in all the herbicide-metabolizing P. rhoeas biotypes, suggesting that a common metabolic system involving P450s is responsible of degrading herbicides affecting both SoAs. Thus, selection pressure with either SAH or imidazolinone ALS inhibitors can select not only for resistance to each of them, but it can also confer cross-resistance between them in P. rhoeas.
