Here we report a novel method of site-selective oxidation of glucose moieties on individual glycopeptides and on a mixture of tryptic glycopeptides. The organometallic catalyst [(neocuproine)PdOAc]2OTf2, that was previously shown to perform regioselective C3-oxidation of glucosides, was used in the scope of this work. The selectivity of the catalyst towards glucose and the sensitivity of specific amino acid residues to oxidation was explored by screening a select panel of glycopeptides in the oxidation reactions. We reveal that glucosylated peptides are more readily oxidized compared to galactosylated peptides, and Thr/Ser-oxidation is a concomitant side-reaction. The oxidation methodol. was also applied to the complex mixture of tryptic glucopeptides that was generated from the fragment of Haemophilus influenzae adhesin glycoprotein. The resulting keto-group of the glucose was further transformed into an oxime functionality, which allows introduction of various groups of interest. The methodol. outlined in this work will allow to perform late-stage modification of glucopeptides as well as selective oxidation and functionalization of tryptic glucopeptides for proteomics anal.

In our search for new bioactive compounds that interfere with the sugar recognition process, we have designed and synthesized C3- and Cs-sym. tripodal receptor-type mols. Among the synthesized C3-sym. 2,4,6-trisubstituted 1,3,5-triazine (TAZ) derivatives, compounds A [2,4,6-tris(2-propoxy)-TAZ] and B [2,4,6-tris(3,4-dimethoxyphenyl)-TAZ] showed high levels of anti-HSV-1 activity. We carried out isothermal titration calorimetry on compound B·HCl in aqueous 25% 2-PrOH solution with some sugar derivatives including Me α/β-D-galactopyranoside (MeO-α/β-Gal), Me α/β-D-mannopyranoside (MeO-α/β-Man) and Me α/β-D-glucopyranoside (MeO-α/β-Glc). The reactions of compound B·HCl with MeO-β-Gal and MeO-α-Man were exothermic, and the obtained thermodn. profiles indicated that both reactions are spontaneous and that there is a considerably large enthalpic contribution (ΔH) in total Gibbs free energy change (ΔG), indicating favorable hydrogen bonding interactions. The reaction of compound B·HCl showed a thermodn. signature different from that of the entropically driven reaction of compound A.

A bacterial resistance gained by microorganisms to classical antimicrobials is current challenges. Searching of antimicrobial agents with new structure and mode of action is an essential strategy of research. Therefore, some acylated derivatives of Me β-D-galactopyranoside were employed as test compounds for in vitro antimicrobial functionality test against five human pathogenic bacteria and two phytopathogenic fungi.For comparative studies, biol. activity of standard antibiotics, Azithromycin and Nystatin were also carried out against these microorganisms. The study revealed that the tested samples exhibited moderate to good antibacterial and antifungal activities. It was also observed that the test substances were more effective against fungal phytopathogens than those of the bacterial strains. Encouragingly, a good number of test compounds exhibited better antimicrobial activity than the standard antibiotics employed. Min. Inhibition Concentration (MIC) and MBC test of Me 2,3,4-tri-O-(3-chlorobenzoyl)-6-O-pivaloyl-β-D-galactopyranoside 12 was conducted good result against S. aureus and MIC, MBC were found to be 312.5 μg/disk and 625 μg/disk, resp. In addition, MFC was invented to be 1250 μg/disk against Candida albicans. In vitro MTT assays revealed that compound 8 was effective against Ehrlich′s ascites carcinoma (EAC) cells, resulting in 12.72% and 2.11% cell growth inhibition at concentrations of 200 and 6.25 μg/mL, resp. So the acylated derivatives of D-galactopyranoside (2-14) may be considered as a potential source for developing new and better antimicrobial agents against a number of pathogenic organisms.

Author is Cosgrove, Sebastian C.; Mattey, Ashley P.; Riese, Michel; Chapman, Michael R.; Birmingham, William R.; Blacker, A. John; Kapur, Nikil; Turner, Nicholas J.; Flitsch, Sabine L..

Galactose Oxidase (GOase) has been used for the scalable and selective C-6′ oxidation of lactose, a waste material from the dairy industry. Generation of the 6′-oxo lactose was achieved with full conversion in batch mode at milligram scale, but further scale-up to gram quantities proved to be challenging because of requirements for high enzyme concentrations and limitation in oxygen cosubstrate availability. To overcome these issues, a continuous-flow system was developed for the bio-oxidation of lactose yielding multigram quantities of product. Using the variant GOase F2, terminal selective oxidations were also observed on a range of oligoglucosides such as maltose. The carbohydrate dialdehydes that were obtained by this highly selective oxidation were chem. further functionalized, establishing the biooxidation as a route to valorize cheap carbohydrates, including waste materials, for building blocks of polymers.

Metabolites can mediate species interactions and the assembly of microbial communities. However, how these chems. relate to the assembly processes and co-occurrence patterns of diazotrophic assemblages in root-associated soils remains largely unknown. Here, we examined the diversity and assembly of diazotrophic communities and further deciphered their links with metabolites on Tibetan Plateau. We found that the distribution of sugars and organic acids in the root-associated soils was significantly correlated with the richness of diazotrophs. The presence of these two soil metabolites explains the variability in diazotrophic community compositions The differential concentrations of these metabolites were significantly linked with the distinctive abundances of diazotrophic taxa in same land types dominated by different plants or dissimilar soils by same plants. The assembly of diazotrophic communities is subject to deterministic ecol. processes, which are widely modulated by the variety and amount of sugars and organic acids. Organic acids, for instance, 3-(4-hydroxyphenyl)propionic acid and citric acid, were effective predictors of the characteristics of diazotrophic assemblages across desert habitats. Diazotrophic co-occurrence networks tended to be more complex and connected within different land types covered by the same plant species. The concentrations of multiple sugars and organic acids were coupled significantly with the distribution of keystone species, such as Azotobacter, Azospirillum, Bradyrhizobium, and Mesorhizobium, in the co-occurrence network. These findings provide new insights into the assembly mechanisms of root-associated diazotrophic communities across the desert ecosystems of the Tibetan Plateau.

Author is Kabir, Syed Rashel; Islam, Jahanur; Ahamed, Selim Md.; Alam, Mohammad Taufiq.

A lectin (designated as ARL) was purified first time from the Asparagus racemosus root with the mol. weight of 14.0 kDa containing about 4.8% carbohydrate. ARL showed hemagglutination activity in both mice and human erythrocytes that were inhibited by three complex sugars among the 26 sugars tested. ARL was thermostable that mostly preserved activity at its optimum pH 8.0. Around 48% and 52.5% human colorectal cancer (HCT-116) cells growth was inhibited by 160μg/mL of ARL and 256μg/mL of previously purified Geodorum densiflorum rhizome lectin (GDL). Induction of apoptosis in HCT-116 cells was confirmed by Hoechst 33342 staining, caspase inhibitors, but ROS generation was only observed for ARL. The expression level of BAX and p53 genes increased with a decrease of PARP gene expression for both lectins. The expression of FAS and FADD were increased with the decrease of WNT after treatment with GDL. ARL inhibited 68% and 26% of Ehrlich ascites carcinoma cell growth in vivo in mice after treating with 3.0 and 1.5 mg/kg/day doses for five consecutive days. ARL increased the expression level of NFκB and arrested S cell cycle phase in EAC cells, in contrast, G2/M phase was arrested by ARL and GDL in HCT-116.

Author is Tong, Yuchen; Feng, Anqi; Hou, Xuan; Zhou, Qixing; Hu, Xiangang.

Single-layer molybdenum disulfide (SLMoS2) are applied as a hot 2D nanosheet in various fields involving water treatments. Both intentional design and environmental or biol. processes induce many nanoholes in SLMoS2. However, the effects of nanoholes on the environmental stability and ecotoxicity of SLMoS2 remain largely unknown. The present work discovered that visible-light irradiation induced nanoholes (diameters, approx. 20 nm) in the plane of SLMoS2, with irregular edges and increased interplanar crystal spacing. The ratios of Mo to S in pristine and transformed SLMoS2 were 0.53 and 0.33, resp. After 96 h exposure at concentrations from 0.1-1 mg/L, the above nanoholes promoted algal division, induced a stress-response hormesis, decreased the generation of •OH and mitigated the cell shrinkage and wall rupture of Chlorella vulgaris induced by SLMoS2. In terms of stress response, the nanohole-bearing SLMoS2 induced fewer vacuoles and polyphosphate bodies of Chlorella vulgaris than the pristine form. Metabolomic anal. revealed that nanoholes perturbed the metabolisms of energy, carbohydrates and fatty acids. This work proposes that nanoholes cause obvious effects on the environmental fate and ecotoxicity of SLMoS2 and that the environmental risks of engineered nanomaterials should be reevaluated using nanohole-bearing rather than pristine forms for testing.
