Volatile Components Identified in the Phenolic Fractions of Wines from Koshu and Zenkoji Grapes

Volatile components of the phenolic fractions from Koshu and Zenkoji wine flavor concentrates were identified by combined gas chromatography-mass spectrometry.The fraction from Koshu wine composed of 13 volatile phenols, 11 fatty acids, 8 lactones, 4 ketones and many alcohols.The volatile compounds identified in the fraction from Zenkoji wine were almost common to those from Koshu wine with only slight differences.The phenolic fraction had no wine like flavor, but possesed a phenolic and disagreeable odor. 13 volatile phenols in Koshu wine and 10 phenols in Zenkoji wine were detected.Five phenols (2,6-di-tert-butyl-4-methylphenol, 3,4-dimethylphenol, 2-methoxy-4-vinylphenol, 2,6-di-tert-butyl-4-ethylphenol and 4-allyl-2,6-dimethoxyphenol) were found for the first time as volatile components of wine and another 11 compounds were also newly detected in Koshu or Zenkoji wines.

The parmodulin NRD-21 is an allosteric inhibitor of PAR1 Gq signaling with improved anti-inflammatory activity and stability

Novel analogs of the allosteric, biased PAR1 ligand ML161 (parmodulin 2, PM2) were prepared in order to identify potential anti-thrombotic and anti-inflammatory compounds of the parmodulin class with improved properties. Investigations of structure-activity relationships of the western portion of the 1,3-diaminobenzene scaffold were performed using an intracellular calcium mobilization assay with endothelial cells, and several heterocycles were identified that inhibited PAR1 at sub-micromolar concentrations. The oxazole NRD-21 was profiled in additional detail, and it was confirmed to act as a selective, reversible, negative allosteric modulator of PAR1. In addition to inhibiting human platelet aggregation, it showed superior anti-inflammatory activity to ML161 in a qPCR assay measuring the expression of tissue factor in response to the cytokine TNF-alpha in endothelial cells. Additionally, NRD-21 is much more plasma stable than ML161, and is a promising lead compound for the parmodulin class for anti-thrombotic and anti-inflammatory indications.

Eight series of quinazoline derivatives bearing 2,3-dihydro-indole or 1,2,3,4-tetrahydroquinoline were designed, synthesized and evaluated for the IC50 values against three cancer cell lines (A549, MCF-7 and PC-3). Most of the forty nine target compounds showed excellent antiproliferative activity against one or several cancer cell lines. The compound 13a showed the best activity against A549, MCF-7 and PC-3 cancer cell lines, with the IC50 values of 1.09 ¡À 0.04 muM, 1.34 ¡À 0.13 muM and 1.23 ¡À 0.09 muM, respectively. Eight selected compounds were further selected to evaluated for the inhibitory activity against EGFR kinase. Three of them showed equal activity against EGFR kinase to positive control afatinib. AnnexinV-FITC, propidium iodide (PI) double staining and acridine orange single staining results indicated that the compound 13a could induce apoptosis of human lung cancer A549 cells.

Functionalised heterogeneous catalysts for sustainable biomass valorisation

Efficient transformation of biomass to value-added chemicals and high-energy density fuels is pivotal for a more sustainable economy and carbon-neutral society. In this framework, developing potential cascade chemical processes using functionalised heterogeneous catalysts is essential because of their versatile roles towards viable biomass valorisation. Advances in materials science and catalysis have provided several innovative strategies for the design of new appealing catalytic materials with well-defined structures and special characteristics. Promising catalytic materials that have paved the way for exciting scientific breakthroughs in biomass upgrading are carbon materials, metal-organic frameworks, solid phase ionic liquids, and magnetic iron oxides. These fascinating catalysts offer unique possibilities to accommodate adequate amounts of acid-base and redox functional species, hence enabling various biomass conversion reactions in a one-pot way. This review therefore aims to provide a comprehensive account of the most significant advances in the development of functionalised heterogeneous catalysts for efficient biomass upgrading. In addition, this review highlights important progress ensued in tailoring the immobilisation of desirable functional groups on particular sites of the above-listed materials, while critically discussing the role of consequent properties on cascade reactions as well as on other vital processes within the bio-refinery. Current challenges and future opportunities towards a rational design of novel functionalised heterogeneous catalysts for sustainable biomass valorisation are also emphasized.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions.Quality Control of (cis-Tetrahydrofuran-2,5-diyl)dimethanol, you can also check out more blogs about2144-40-3
