A tri-antennary Man(9)GlcNAc(2) glycan on the surface of endoplasmic reticulum (ER) glycoproteins functions as a glycoprotein secretion or degradation signal after regioselective cleavage of the terminal alpha-1,2-mannose residue of each branch. Four alpha-1,2-mannosidases-ER mannosidase I, ER degradation-enhancing alpha-mannosidase-like protein 1 (EDEM1), EDEM2, and EDEM3-are involved in the production of these signal glycans. Although selective production of signal glycans is important in determining the fate of glycoproteins, the branch-discrimination abilities of the alpha-1,2-mannosidases are not well understood. A structural feature of the Man(9)GlcNAc(2) glycan is that all terminal glycosidic linkages of the three branches are of the alpha-1,2 type, while the adjacent inner glycosidic linkages are different. In this study, we examined whether the alpha-1,2-mannosidases showed branch specificity by discriminating between different inner glycosides. Four trisaccharides with different glycosidic linkages [Man alpha 1-2Man alpha 1-2Man (natural A-branch), Man alpha 1-2Man alpha 1-3Man (natural B-branch), Man alpha 1-2Man alpha 1-6Man (natural C-branch), and Man alpha 1-2Man alpha 1-4Man (unnatural D-branch)] were synthesized and used to evaluate the hypothesis. When synthesizing these oligosaccharides, highly stereoselective glycosylation was achieved with a high yield in each case by adding a weak base or tuning the polarity of the mixed solvent. Enzymatic hydrolysis of the synthetic trisaccharides by a mouse liver ER fraction containing the target enzymes showed that the ER alpha-1,2-mannosidases had clear specificity for the trisaccharides in the order of A-branch > B-branch > C-branch approximate to D-branch. Various competitive experiments have revealed for the first time that alpha-1,2-mannosidase with inner glycoside specificity is present in the ER. Our findings suggest that exo-acting ER alpha-1,2-mannosidases can discriminate between endo-glycosidic linkages.

Oxidative hydroxylation of arylboronic acids to the corresponding phenolic compounds under metal- and base-free aerobic conditions is successfully demonstrated on a biopolymer support (chitosan or chitosan immobilized onto carbon nanotubes (CNT@Chitosan)). Hydrogen peroxide, as an eco-friendly oxidant, is compatible with the biopolymer supports and provides hydroxylation products in an efficient manner. The CNT@chitosan biopolymer support is particularly interesting for its potential recyclability. (C) 2019 Elsevier Ltd. All rights reserved.

Synthesis and characterization of novel coumarins containing carborane units were described. The breakdown reactions of cyclic oxonium derivatives of cobalt bis (1,2-dicarbollide) and closo-dodecaborate anions with a series of 7-hydroxy-3-substituted coumarins led to conjugates attached via C-7 position of the coumarin unit. The corresponding reactions of cobalt bis (1,2-dicarbollide) anion with 3-(4-hydroxybenzoyl)-7-methoxy-2H-chromen-2-one led to conjugates attached via C-3 position. Novel conjugates were isolated in the form of alkali metal salts. Therefore, these conjugates are of interest for the fluorescent study in aqua media. (C) 2020 Elsevier B.V. All rights reserved.

Background: Much attention has been focused on heterogeneous catalysts. Reactions with these recoverable and reusable catalysts are clean, selective with high efficiency. Among the heterogeneous solid acid catalyst in organic synthesis, Carbon-Based Solid Acids (CBSAs), which are important solid acid with many practical and research applications have been extensively studied. In this work, green Pistachio peel, a biomass waste, was converted into a novel carbon-based solid acid catalyst (Pis-SO3H). Objective: The aim of this work is to synthesize highly sulfonated carbon as an efficient, recyclable, nontoxic solid acid catalyst by simultaneous sulfonation, dehydration and carbonization of green Pistachio peel as biomass and investigate the catalytic activity of Pis-SO3H in acetalization, thioacetalization, acylation of aldehydes and synthesis of 3,3′-Arylmethylene-bis(4-hydroxycoumarin) derivatives. Methods: Pis-SO3H was synthesized by an integrated fast one- step hydrothermal carbonization and sulfonation process in the presence of sulfuric acid. The characterization of the physicochemical properties of Pis-SO3H was achieved by XRD, FT-IR, FE-SEM, and elemental analysis. Results: The result of acid-base titration showed that the total acidity of the catalyst was 7.75 mmol H(+)g(-1). This new heterogeneous catalyst has been efficiently used for the chemoselective thioacetalization, acetalization and acylation of aldehyde and the synthesis of biscoumarins under solvent-free conditions. All the reactions work easily in high yields. The antimicrobial activity of some of the biscoumarins was evaluated in screening by disk diffusion assay for the zone of inhibition. Conclusion: The catalytic activity of the Pis-SO3H was investigated during acetalization, thioacetalization, acylation and synthesis of biscoumarins. The results of protection of carbonyl groups and synthesis of biscoumarins in the present work offer effective alternatives for environmentally friendly utilization of abundant biomass waste.

Self-immolation (SI) is the key principle of ProTide nucleotide prodrugs such as remdesivir, which is currently used to treat COVID-19 patients. Developing novel tailor-made SI systems requires new analytical methods for the detection and monitoring of SI. We developed a robust method for SI analysis using novel phosphate-based SI linkers with NMR traceable cyclic intermediates to distinguish SI from alternative fragmentation pathways and to monitor cargo release in real time.

A series of hybrids 10a-v based on coumarin/pyrazole oxime have been synthesized, and exhibit good to excellent antitumor activities. Compound 10n has shown remarkable anticancer effect on SMMC-7721 cells (IC50 = 2.08 mu M), which is considerably lower than 5-FU (IC50 = 37.8 mu M) and similar to ADM (IC50 = 2.67 mu M), with little effect on normal hepatic cells LO2. Notably, the suppression experiments of metastatic activities reveal that 10n also displays significant anti-metastasis effects through inhibiting cell migration and invasion in highly metastatic SMMC-7721 cell line, and dose-dependently reverses TGF-beta 1-induced epithelial-mesenchymal transition (EMT) procedure better than ADM. Finally, 10n also possesses low acute toxicity and potent tumor growth inhibitory property against SMMC-7721 cell lines in vivo. Our findings suggest that novel coumarin/pyrazole oxime hybrids are promising therapeutic agent candidates for further research. (C) 2019 Elsevier Masson SAS. All rights reserved.

Ethnopharmacological relevance: Oryeong-san (ORS) is a traditional formula that has long been used for the treatment of dysfunctions of body fluids and electrolyte homeostasis in Korea, China and Japan. Recent reports have shown that ORS may suppress hypertension by controlling the renin-angiotensin-aldosterone system (RAAS) in the kidney, but its action mechanism has not been well defined. Aim of the study: The aim of this study was to decipher the ORS mechanisms in the treatment of hypertension using a systems pharmacology approach. Materials and methods: The compounds of ORS were obtained from the TM-MC (database of medicinal materials and chemical compounds in Northeast Asian traditional medicine), and the drug-likeness (DL) and oral bioavailability (OB) of the compounds were evaluated. The potential targets of the compounds were identified using various pharmacology databases. To analyze the mechanisms of the ORS for hypertension, a Compound-Target Disease (C-T-D) network was established with respect to the genes related to hypertension. Results: A screening evaluation of the DL and OB of the ORS compounds identified a list of 232 active compounds. The pharmacological activity of the targets was investigated by exploring the interaction network between the compounds and the targets. Analysis of the interactions between the compounds and the hypertension related targets revealed that 14 ORS compounds regulate the RAAS and vasoconstrictors in the kidney. Conclusions: This study used the systems pharmacology approach to decipher the mechanisms of action of ORS for the treatment of hypertension. When hypertension drugs and ORS are used in combination for treatment, possible side effects should be considered because most hypertension drugs are related to the RAAS. The results of this study may provide clues to not only analyze the pharmacological activity of ORS for the treatment of hypertension but other diseases as well.

Mild oxetane opening by soft carbon nucleophiles has been developed for efficient C-C bond formation. In the presence of LiNTf2 or TBSNTf2 as catalyst, silyl ketene acetals were found to be effective nucleophiles to generate a wide range of highly oxygenated molecules, which are key substructure in natural products like polyketides. Furthermore, intramolecular oxetane opening by a styrene-based carbon nucleophile via a Prins-type process was also achieved with Sc(OTf)(3) as catalyst, leading to efficient formation of the useful 2,3-dihydrobenzo[b]oxepine skeleton.
