Photochemical Radical C-H Halogenation of Benzyl N-Methyliminodiacetyl (MIDA) Boronates: Synthesis of alpha-Functionalized Alkyl Boronates

alpha-Haloboronates are useful organic synthons that can be converted to a diverse array of alpha-substituted alkyl borons. Methods to alpha-haloboronates are limiting and often suffer from harsh reaction conditions. Reported herein is a photochemical radical C-H halogenation of benzyl N-methyliminodiacetyl (MIDA) boronates. Fluorination, chlorination, and bromination reactions were effective by using this protocol. Upon reaction with different nucleophiles, the C-Br bond in the brominated product could be readily transformed to a series of C-C, C-O, C-N, C-S, C-P, and C-I bonds, some of which are difficult to forge with alpha-halo sp(2)-B boronate esters. An activation effect of B(MIDA) moiety was found.

Synthesis of Luminescent Fused Imidazole Bicyclic Acetic Esters by a Multicomponent Palladium Iodide-Catalyzed Oxidative Alkoxycarbonylation Approach

A new multicomponent catalytic approach to important fused imidazole bicyclic acetic esters, whose core is present in many biologically active principles, is presented. It is based on the sequential cyclization-alkoxycarbonylation-isomerization of readily available N-heterocyclic propargylamine derivatives, carried out under oxidative conditions using a simple catalytic system consisting of PdI2 (1 mol%) in conjunction with KI (1 equiv.), in the presence of AcONa as additive (1 equiv.) at 100 degrees C under 20 bar of a 4 : 1 mixture CO-air. Under the optimized conditions, several N-(prop-2-yn-1-yl)pyridin-2-amines were smoothly converted into alkyl 2-(imidazo[1,2-a]pyridin-3-yl)acetates in fair yields (51-77 %). The method was also applied to the conversion of N-(prop-2-yn-1-yl)pyrimidin-2-amine into 2-(imidazo[1,2-a]pyrimidin-3-yl)acetate and of N-(prop-2-yn-1-yl)pyrazin-2-amine into 2-(imidazo[1,2-a]pyrazin-3-yl)acetate. Some of the newly synthesized bicyclic derivatives have shown promising luminescence properties.

The Oxidation of S-Acetyl by Nitrite: Mechanism and Application

Straightforward S-S bond formation via the oxidation of S-acetyl group by nitrite was observed and the mechanism was explored in this study. The observed reaction was found to be initiated via a S-nitrosylation followed by the S-S bond formation that accompanies nitrite oxide (NO) release. The reaction approach was further analyzed by quantum chemical studies, surpporting a mechanism of first generating nitrous ester. Unlike S-nitrosylation between thiols and nitrite proceeding at a strong alkaline condition due to the formation of hydroxyl anion, the S-nitrosylation between S-acetyl and nitrite proceed at a condition close to neutrality due to the formation of acetate instead. Using this reaction, per-O-acetylated glycosyl disulfides were obtained in high yields at mild condition. Furthermore, per-O-acetylated glycosyl 1-thiols were also efficiently prepared starting from per-acetylated 1-thio-glycoses in a one-pot reaction including the oxidation of S-acetyl group by nitrite and the reduction of disulfides.

Modular Synthesis of Heparan Sulfate Oligosaccharides Having N-Acetyl and N-Sulfate Moieties

Heparan sulfates are structurally diverse sulfated polysaccharides that reside at the surface of all animal cells where they can interact with a multitude of proteins, thereby modulating a wide range of physiological and disease processes. We describe here a modular synthetic methodology that can provide libraries of heparan sulfate oligosaccharides that have glucosamine residues modified by different patterns of N-acetyl and N-sulfate moieties. It is based on the use of glycosyl donors that are modified at C2 by an azido- or trifluoromethylphenyl-methanimine moiety, which allowed the selective installation of alpha-glycosides. The amino protecting groups can be selectively unmasked by a reduction or acid treatment, allowing the installation of N-acetyl and N-sulfate moieties, respectively. In combination with the orthogonal hydroxyl protecting groups levulinic (Lev) ester, thexyldimethylsilyl (TDS) ether, allyloxycarbonate (Alloc), and 9-fluorenylmethyl carbonate (Fmoc), different patterns of O-sulfation can be installed. The methodology was applied to prepare four hexasaccharides that differ in the pattern of N- and O-sulfation. These compounds, together with a number of previously prepared HS oligosaccharides, were printed as a glycan microarray to examine the binding selectivities of several HS-binding proteins.

Intramolecular benzyl cation transfer in the gas-phase fragmentation of protonated benzyl phenyl sulfones

In this study, the gas-phase fragmentations of protonated benzyl phenyl sulfones were investigated by electrospray ionization tandem mass spectrometry (ESI-MSn). Upon collisional activation, several characteristic fragment ions were observed, and the similar results occurred with different substituted benzyl phenyl sulfones. A mechanism involving an intramolecular benzyl cation transfer and the formation of intermediate ion was proposed and further identified by density functional theory (DFT) calculations. In addition, a reference compound, benzenesulfinic acid benzyl ester, has been synthesized, and its protonated ion has the same gas-phase behavior as compared to the protonated benzyl phenyl sulfone. This work provides access to some insight into the intramolecular benzyl-transfer reactions of benzyl phenyl sulfones in the gas phase and orients the characteristic peaks in collision-induced dissociation spectrometry (CID-MS).

Nimodipine attenuates dibutyl phthalate-induced learning and memory impairment in kun ming mice: An in vivo study based on bioinformatics analysis

Dibutyl phthalate (DBP), a typical representative of phthalate esters (PAEs), is used as a plasticizer in various industrial applications and has been reported to be responsible for neurobehavioral changes. Despite mounting evidence showing that nimodipine (Nim) palys a neuropharmacological and psychopharmacological role in neurons, the attenuating effects of Nim on learning and memory impairment induced by DBP exposure remain unknown. Based on bioinformatics analysis we found that the biological processes affected by both DBP and Nim may involve the calcium signaling pathway, the MAPK signaling pathway and the apoptosis pathway. The results of an in vivo study confirmed that DBP affects the levels of Ca2+-related proteins, up-regulates phosphorylated -ERK1/2 expression and results in hippocampal neuronal damage and apoptosis, whereas Nim as a Ca2+ antagonist, has a certain neuroprotective role to avoid these adverse effects. Our data suggest that Nim could be used to attenuate the learning and memory impairment in DBP-exposed mice, to down-regulate intracellular Ca2+ levels, subordinate the ERK1/2 pathway and attenuate apoptosis in hippocampal tissue.

Are we underestimating the sources of microplastic pollution in terrestrial environment?

Microplastics (MPs, plastic particles < 5 mm) are an ever-increasing global issue due to their widespread occurrence in the environment and negative effects on organisms. Currently, more than 96 % of MPs studies are related to marine systems. However, the majority of marine MPs pollution has been confirmed to originate from land-based sources, evidence of MPs in the terrestrial system cannot be overlooked. In this manuscript, up-todate knowledge regarding the sources and occurrence of MPs from the terrestrial system is comprehensively reviewed. According to the different studies both in China and abroad, microfibers derived from textile washing attributed approximately 35 % of the MPs identified in the aquatic system. Additionally, personal care and cosmetic products, tires, agricultural plastic films, artificial turfs and road paints, landfill, littering, packaging and construction industry can also release MPs to the environment. The aquatic system plays an important role in MPs transport. By using a one-way ANOVA test, polypropylene (PP) and polyethylene (PE) accounted for significantly higher percentages than other polymer compositions in surface water. Polyamide (PA) and PP accounted for the majority of polymers in soils. PP, PE, and polystyrene (PS) presented an overwhelming proportion in sediment. Atmospheric deposition presents a new vehicle for entering into the wider environment. More research is urgently required on the topic of exposure risk of atmospheric MPs via inhalation. Morphological characteristics including shapes, sizes, and colors have been discussed among waters, soils, sediments and airborne. These source-occurrence implications continuum summaries can bring us new insights that we cannot underestimate the severity of MPs from land-based sources and should pay more attention to MPs contamination in the terrestrial ecosystem.

In Vivo Characterization of the Toxicological Properties of DPhP, One of the Main Degradation Products of Aryl Phosphate Esters

BACKGROUND: Aryl phosphate esters (APEs) are widely used and commonly present in the environment. Health hazards associated with these compounds remain largely unknown and the effects of diphenyl phosphate (DPhP), one of their most frequent derivatives, are poorly characterized. OBJECTIVE: Our aim was to investigate whether DPhP per se may represent a more relevant marker of exposure to APEs than direct assessment of their concentration and determine its potential deleterious biological effects in chronically exposed mice. METHODS: Conventional animals (FVB mice) were acutely or chronically exposed to relevant doses of DPhP or to triphenyl phosphate (TPhP), one of its main precursors. Both molecules were measured in blood and other tissues by liquid chromatography-mass spectrometry (LC-MS). Effects of chronic DPhP exposure were addressed through liver multi-omics analysis to determine the corresponding metabolic profile. Deep statistical exploration was performed to extract correlated information, guiding further physiological analyses. RESULTS: Multi-omics analysis confirmed the existence of biological effects of DPhP, even at a very low dose of 0:1mg/mL in drinking water. Chemical structural homology and pathway mapping demonstrated a clear reduction of the fatty acid catabolic processes centered on acylcarnitine and mitochondrial beta-oxidation in mice exposed to DPhP in comparison with those treated with vehicle. An interesting finding was that in mice exposed to DPhP, mRNA, expression of genes involved in lipid catabolic processes and regulated by peroxisome proliferator-activated receptor alpha (PPAR alpha) was lower than that in vehicle-treated mice. Immunohistochemistry analysis showed a specific down-regulation of HMGCS2, a kernel target gene of PPAR alpha. Overall, DPhP absorption disrupted body weight-gain processes. CONCLUSIONS: Our results suggest that in mice, the effects of chronic exposure to DPhP, even at a low dose, are not negligible. Fatty acid metabolism in the liver is essential for controlling fast and feast periods, with adverse consequences on the overall physiology. Therefore, the impact of DPhP on circulating fat, cardiovascular pathologies and metabolic disease incidence deserves, in light of our results, further investigations.
