Monteiro, Sara H. M. C. published the artcileEffects of ultrasound energy density on the non-thermal pasteurization of chocolate milk beverage, Recommanded Product: 3-Hydroxydihydrofuran-2(3H)-one, the publication is Ultrasonics Sonochemistry (2018), 1-10, database is CAplus and MEDLINE.

This study presents the emerging high-intensity ultrasound (HIUS) processing as a non-thermal alternative to high-temperature short-time pasteurization (HTST). Chocolate milk beverage (CMB) was subjected to different ultrasound energy densities (0.3-3.0 kJ/cm³), as compared to HTST pasteurization (72°C/15 s) aimed to verify the effect of the HIUS processing on the microbiol. and physicochem. characteristics of the beverage. The application of HIUS at an energy d. of 3.0 kJ/cm³ was able to reduce 3.56 ± 0.02 logarithmic cycles in the total aerobic counts. In addition, the ultrasound energy d. affected the phys. properties of the beverage as the size distribution of fat globule and rheol. behavior, as well as the chem. properties such as antioxidant activity, ACE inhibitory activity, fatty acid profile, and volatile profile. In general, the different energetic densities used as a non-thermal method of pasteurization of CMB were more effective when compared to the conventional pasteurization by HTST, since they improved the microbiol. and physicochem. quality, besides preserving the bioactive compounds and the nutritional quality of the product.

Coutinho, Nathalia M. published the artcileProcessing chocolate milk drink by low-pressure cold plasma technology, Related Products of tetrahydrofurans, the publication is Food Chemistry (2019), 276-283, database is CAplus and MEDLINE.

This study aimed to evaluate the effect of the process time (5, 10, and 15 min) and flow rate (10, 20, and 30 mL/min) of cold plasma technol. on physio-chem. characteristics (pH), bioactive compounds (DPPD, Total Phenolic Compounds, ACE-inhibitory activity values), fatty acid composition, and volatile compounds profile of chocolate milk drink. The mild (lower flow rate and process time) and more severe (higher flow rate and process time) conditions led to a reduction of the bioactive compounds (total phenolic compounds and ACE-inhibitory activity), changes in fatty acid composition (increased saturated fatty acid and decreased monounsaturated fatty acid and polyunsaturated fatty acid), less favorable health indexes (higher atherogenic, thrombogenic and hypercholesterolemic saturated fatty acids and lower desired fatty acids), and lower number of volatile compounds In contrast, in intermediate cold plasma conditions, an adequate concentration of bioactive compounds, fatty acid composition, and health indexes, and increased number of volatile compounds (ketones, esters, and lactones) were observed Overall, cold plasma technol. has proven to be an interesting alternative to chocolate milk drinks, being of paramount importance the study of the cold plasma process parameters.

Min, Hyun Su published the artcileChemical gas-generating nanoparticles for tumor-targeted ultrasound imaging and ultrasound-triggered drug delivery, Computed Properties of 19444-84-9, the publication is Biomaterials (2016), 57-70, database is CAplus and MEDLINE.

Although there is great versatility of ultrasound (US) technologies in the real clin. field, one main tech. challenge is the compromising of high quality of echo properties and size engineering of ultrasound contrast agents (UCAs); a high echo property is offset by reducing particle size. Herein, a new strategy for overcoming the dilemma by devising chem. gas (CO₂) generating carbonate copolymer nanoparticles (Gas-NPs), which are clearly distinguished from the conventional gas-encapsulated micro-sized UCAs. More importantly, Gas-NPs could be readily engineered to strengthen the desirable in vivo physicochem. properties for nano-sized drug carriers with higher tumor targeting ability, as well as the high quality of echo properties for tumor-targeted US imaging. In tumor-bearing mice, anticancer drug-loaded Gas-NPs showed the desirable theranostic functions for US-triggered drug delivery, even after i.v. injection. In this regard, and as demonstrated in the aforementioned study, our technol. could serve a highly effective platform in building theranostic UCAs with great sophistication and therapeutic applicability in tumor-targeted US imaging and US-triggered drug delivery.

As alcs. are ubiquitous throughout chem. science, this functional group represents a highly attractive starting material for forging new C-C bonds. Here, it is demonstrated that the combination of anodic preparation of alkoxy triphenylphosphonium ion and nickel catalyzed cathodic reductive cross-coupling provides an efficient method to construct C(sp²)-C(sp³) bonds, in which free alcs. and aryl bromides e.g., bromobenzene-both readily available chems. can be directly used as coupling partners yielding arene derivative e.g., I. This nickel catalyzed paired electrolysis reaction features a broad substrate scope bearing a wide gamut of functionalities, which was illustrated by the late-stage arylation of several structurally complex natural products and pharmaceuticals.

A novel series of hydroxy-anthraquinone derivatives I [R = 1,2-di-OH, 2,3-di-OH, 1-Me-2,3-di-OH, etc.; R¹ = 5-OH, 8-OH] was synthesized via Friedel-Crafts acylation reaction of phenols and hydroxyphthalic anhydride and identified as potential antileishmanial chemotype. Among the synthesized analogs I [R = 5-OH, R¹ = 3,5-di-OH; R = 8-OH, R¹ = 1,4-di-OH] exhibited better antileishmanial activity against intracellular amastigotes form of Leishmania donovani. The compounds I were also non-toxic toward Vero cells. Compounds I [R = 5-OH, 8-OH; R¹ = 1,2-di-OH, 1,2,3-tri-OH] also showed significant in vitro activity against intracellular amastigotes form of Leishmania donovani.

Fathalinejad, Samin published the artcileChemical composition analysis of carbohydrate fragmentation products, Formula: C4H6O3, the publication is Journal of Analytical and Applied Pyrolysis (2021), 105112, database is CAplus.

Fragmentation of simple sugars, using fluidized thermal bed cracking, results in a mixture that contains a variety of polar oxygenated compounds, some yet unknown to the industries. This lack of understanding of the product composition, hinders the downstream processes in conversion of sugars to useful chems. The aim of this study was fourfold: to develop a GC-MS identification workflow for carbohydrate fragmentation compounds, to build a library of compounds detected by five GC-MS methods including liquid injection, liquid-liquid extraction, static headspace, solid-phase microextraction and derivatization, to investigate and compare the compound coverage of the five methods, and finally investigate possible reaction pathways for some of the analytes in the mixture The anal. was done on a mixture of seven representative sugar fragmentation samples. The identification workflow was based on mass spectral match factors (>80%), retention indexes and anal. standards A total of 389 compounds were detected, out of which, 46 compounds were fully identified (through confirmatory anal. of anal. standards), 87 were tentatively identified (spectral match factors above 80%), 71 were un-identified with spectral match factors of below 80% and 185 were discarded (contaminants in blanks, etc.). The production pathway for some of the identified compounds in the sugar conversion mixtures were also discussed. In conclusion, solid-phase microextraction detected the highest number of analytes (93), mostly volatile organic compounds and the derivatization GC-MS technique detected the lowest number of analytes (19) but was the only method to detect the largest mols. (C₆-C₁₂) in size. This library of CF products can be used as a suspect-screening database for other biomass fragmentation mixtures

Jensen, Pernille Rose published the artcileProbing the Lewis Acid Catalyzed Acyclic Pathway of Carbohydrate Conversion in Methanol by In Situ NMR, Application of 3-Hydroxydihydrofuran-2(3H)-one, the publication is ChemCatChem (2019), 11(20), 5077-5084, database is CAplus.

Future bioindustries will rely on the formation of diverse chems. at high yield through various reaction pathways. These pathways include reactions to a series of alpha-hydroxy esters and acids that can be formed from the conversion of C3-C6 carbohydrates by Lewis acidic catalysts in alcs. and water. Definitive kinetic and mechanistic insights to support the development of carbohydrate conversion processes are arguably less developed than for analogous biocatalytic processes. Here, we visualize acyclic pathways of carbohydrate dehydration, using the acyclic C4 carbohydrate erythrulose as a probe mol. for the conversion by homogeneous SnCl₄ in methanol. In situ studies allow the detection of previously postulated intermediates, identify the branch point to competing products and provide energetic and mechanistic insight by kinetic anal. Reversibility of reactions, stereoselectivity and differential propensity for deuterium incorporation in competing pathways can be tracked by the formation of compounds with asym. mass distribution.

Peng, Yuhan published the artcileAnalysis of pyrolysis behaviors of biomass extractives via non-linear stepwise heating program based on Gaussian multi-peak fitting of differential thermogravimetric curve, Quality Control of 19444-84-9, the publication is Thermochimica Acta (2021), 178976, database is CAplus.

The thermal decomposition of extractives can yield addnl. products, resulting in a different final product distribution of bio-oil, especially for extractives-rich biomass. However, the thermal decomposition behavior of extractives themselves has long been ignored, but deserves deep investigation. Herein, the non-linear stepwise heating program based on Gaussian multi-peak fitting of differential thermogravimetric curve for biomass extractives was designed. Using this stepwise heating program, the pyrolysis process of different chem. substances in biomass extractives was effectively decoupled and systematically studied. As for water-soluble extractives, the evaporation of volatile substances, the thermal decomposition of water-soluble carbohydrates, phenolic substances, and nitrogenous substances proceed in sequence with the increase of temperature during the pyrolysis process. With regard to liposol. extractives, the pyrolysis included the volatilization of endogenous substances and the thermal decomposition of different lipids into olefins. This work provides a systematic understanding of thermal decomposition process in the extractives of lignocellulosic biomass.

Abstract: Pseudomonas aeruginosa is one of the vulnerable opportunistic pathogens associated with nosocomial infections, cystic fibrosis, burn wounds and surgical site infections. Several studies have reported that quorum sensing (QS) systems are controlled the P. aeruginosa pathogenicity. Hence, the targeting of QS considered as an alternative approach to control P. aeruginosa infections. This study aimed to evaluate the anti-quorum sensing and antibiofilm inhibitory potential of Musa paradisiaca against Chromobacterium violaceum (ATCC 12472) and Pseudomonas aeruginosa. The methanol extract of M. paradisiacsa exhibits that better antibiofilm potential against P. aeruginosa. Then, the crude methanol extract was subjected to purify by column chromatog. and collected the fractions. The mass-spectrometric anal. of a methanol extract of M. paradisiaca revealed that 1,8-cineole is the major compounds 1, 8-cineole significantly inhibited the QS regulated violacein production in C. violaceum. Moreover, 1,8-cineole significantly inhibited the QS mediated virulence production and biofilm formation of P. aeruginosa without affecting their growth. The real-time PCR anal. showed the downregulation of autoinducer synthase and transcriptional regulator genes upon 1,8-cineole treatment. The findings of the present study strongly suggested that metabolite of M. paradisiaca impedes P. aeruginosa QS system and associated virulence productions.
