A review. Resveratrol is a natural polyphenol derived from grapes, berries, red wine, peanuts amongst other fruits and nuts. Beneficial effects such as anti-inflammatory, antioxidant, hepatoprotective, neuroprotective, cardioprotective, renoprotective, anti-obesity, anti-diabetic, and anti-cancer of resveratrol have been demonstrated by preclin. and clin. research. A possibility is that these therapeutical effects are associated with modulation of the Nrf2 signaling pathway in the following way: resveratrol may potentiate Nrf2 signaling through blockage of Keap1, by means of changing the Nrf2 mediators, its expression and its nuclear translocation. This article reviews the evidence of the Nrf2 modulating hypothesis as a possible mol. mechanism underlying the medicinal properties of resveratrol.

Klare, Juliane; Rurik, Marc; Rottmann, Eric; Bollen, Anke; Kohlbacher, Oliver; Fischer, Markus; Hackl, Thomas published the artcile< Determination of the Geographical Origin of Asparagus officinalis L. by 1H NMR Spectroscopy>, Computed Properties of 492-62-6, the main research area is Asparagus geog NMR spectroscopy; NMR; asparagus; food fraud; geographical origin; support vector machine.

Food authenticity concerning the geog. origin becomes increasingly important for consumers, food industries, and food authorities. In this study, nontargeted1H NMR metabolomics combined with machine learning methodologies was applied to successfully distinguish the geog. origin of 237 samples of white asparagus from Germany, Poland, The Netherlands, Spain, Greece, and Peru. Support vector classification of the geog. origin achieved an accuracy of 91.5% for the entire sample set and 87.8% after undersampling the majority class. Important regions of the spectra could be identified and assigned to potential chem. markers. A subset of samples was compared to isotope-ratio mass spectrometry (IRMS), an established method for the determination of origin of white asparagus in Germany. Here, SVM classification led to accuracies of 79.4% for NMR and 70.9% for IRMS. Finally, the classification of asparagus from different German regions was evaluated, and the influence of year and variety was analyzed.

Yi, Xiangli; Hu, Xile published the artcile< Intermolecular oxidative amination of unactivated alkenes by dual photoredox and copper catalysis>, Application In Synthesis of 627-27-0, the main research area is alkene carbomate iridium catalyst photochem regioselective diastereoselective oxidative amination; alkenyl carbamate preparation fluorescence quenching redox potential.

Oxidative amination of alkenes via amidyl radical addition was potentially an efficient method to generate allylic amines, which were versatile synthetic intermediates to bioactive compounds and organic materials. Here by combining photochem. generation of amidyl radicals with Cu-mediated β-H elimination of alkyl radicals, intermol. oxidative amination of unactivated alkenes was developed. The reaction relies on tandem photoredox and copper catalysis and works for both terminal and internal alkenes. The radical nature of the reaction and the mild conditions lead to high functional group tolerance.

Yuan, Li; Zhou, Mengmeng; Huang, Dawei; Wasan, Harpreet S.; Zhang, Kai; Sun, Leitao; Huang, Hong; Ma, Shenglin; Shen, Minhe; Ruan, Shanming published the artcile< Resveratrol inhibits the invasion and metastasis of colon cancer through reversal of epithelial- mesenchymal transition via the AKT/GSK-3beta/Snail signaling pathway>, Application In Synthesis of 501-36-0 , the main research area is resveratrol AKT GSK Snail colon cancer EMT signaling pathway.

The identification of safe and effective drugs that inhibit tumor invasion and metastasis is required to improve the clin. outcome of patients with colon cancer. The present study aimed to investigate the inhibitory effects and possible mechanisms of action of resveratrol against the invasion and metastasis of colon cancer. AKT1-knockdown SW480 and SW620 colon cancer cells were used to detect the effects of resveratrol on cell invasion and metastasis, as well as changes in the expression of epithelial-mesenchymal transition (EMT) markers and serine/threonine kinase (AKT)/glycogen synthase kinase (GSK)-3beta/Snail signaling pathway-related mols. in vitro. Furthermore, nude mice were inoculated with SW480 cells in the tail vein to establish an in vivo lung metastasis model of colon cancer, to investigate the effects of resveratrol on lung metastasis in colon cancer. The results revealed that resveratrol treatment and AKT1 knockdown significantly inhibited cell migration and invasion in colon cancer, and markedly increased E-cadherin expression and decreased that of N-cadherin, phospho (p)-AKT1, p-GSK-3beta, and Snail in colon cancer both in vitro and in vivo. Furthermore, the effects of resveratrol were significantly weaker in the AKT1-knockdown cells. In conclusion, resveratrol may suppress the invasion and metastasis of colon cancer through reversal of EMT via the AKT/GSK-3beta/Snail signaling pathway.

Zeng, Huawei; Umar, Shahid; Liu, Zhenhua; Bukowski, Michael R. published the artcile< Azoxymethane Alters the Plasma Metabolome to a Greater Extent in Mice Fed a High-Fat Diet Compared to an AIN-93 Diet>, Application of C6H10O8, the main research area is azoxymethane plasma metabolome dihydrocholesterol cholesterol; aberrant crypt foci; azoxymethane; colon cancer; high-fat diet; inflammation; metabolome; obesity.

Consumption of a high-fat diet (HFD) links obesity to colon cancer in humans. Our data show that a HFD (45% energy fat vs. 16% energy fat in an AIN-93 diet (AIN)) promotes azoxymethane (AOM)-induced colonic aberrant crypt foci (ACF) formation in a mouse cancer model. However, the underlying metabolic basis remains to be determined In the present study, we hypothesize that AOM treatment results in different plasma metabolomic responses in diet-induced obese mice. An untargeted metabolomic anal. was performed on the plasma samples by gas chromatog. time-of-flight mass spectrometry (GC-TOF-MS). We found that 53 of 144 identified metabolites were different between the 4 groups of mice (AIN, AIN + AOM, HFD, HFD + AOM), and sparse partial least-squares discriminant anal. showed a separation between the HFD and HFD + AOM groups but not the AIN and AIN + AOM groups. Moreover, the concentrations of dihydrocholesterol and cholesterol were inversely associated with AOM-induced colonic ACF formation. Functional pathway analyses indicated that diets and AOM-induced colonic ACF modulated five metabolic pathways. Collectively, in addition to differential plasma metabolomic responses, AOM treatment decreases dihydrocholesterol and cholesterol levels and alters the composition of plasma metabolome to a greater extent in mice fed a HFD compared to the AIN.

Emran, Mohammed Y.; Shenashen, Mohamed A.; El-Safty, Sherif A.; Reda, Abdullah; Selim, Mahmoud M. published the artcile< Microporous P-doped carbon spheres sensory electrode for voltammetry and amperometry adrenaline screening in human fluids>, Application of C6H12O6, the main research area is phosphorus carbon sphere sensory electrode voltammetry amperometry adrenaline human; Adrenaline; Biosensors; Electrochemical sensors/biosensors; Human serum; Nanoporous carbon; P-doped carbon spheres.

An electrochem. sensor-based phosphorus-doped microporous carbon spheroidal structures (P-MCSs) has been designed for selective adrenaline (ADR) signaling in human blood serum. The P-MCS electrode sensor is built with heterogeneous surface alignments including multiple porous sizes with open holes and meso-/macro-grooves, rough surface curvatures, and integral morphol. with interconnected and conjugated microspheres. In addition, the P atom-doped graphitic carbon forms highly active centers, increases charge mobility on the electrode surface, creates abundant active centers with facile functionalization, and induces binding to ADR mols. The designed P-MCS electrode exhibits ultrasensitive monitoring of ADR with a low detection limit of 0.002 μM and high sensitivity of 4330 μA μM-1 cm-2. In addition, two electrochem. techniques, namely, square wave voltammetry (SWV) and chronoamperometry (CA), were used; these techniques achieve high stability, fast response, and a wide linear range from 0.01 to 6 μM. The sensing assays based on P-MCSs provide evidence of the formation of active interfacial surface-to-ADR binding sites, high electron diffusion, and heavy target loads along with/without a plane of spheroids. Thus, P-MCSs can be used for the routine monitoring of ADR in human blood serum, providing a fast response, and requiring highly economical materials at extremely low concentrations Electrode surface modulation based on P-doped carbon spheres (P-MCS) exhibits high electrochem. activity with fast charge transport, multi-diffusible active centers, high loading of ADR, and facile mol./electron diffusion at its surface. The P-MCS sensitively and selectively detects the ADR in human fluids and can be used for clin. investigation of some neuronal diseases such as Alzheimer diseases.

Nasrallah, Daniel J.; Zehnder, Troy E.; Ludwig, Jacob R.; Steigerwald, Daniel C.; Kiernicki, John J.; Szymczak, Nathaniel K.; Schindler, Corinna S. published the artcile< Hydrazone and Oxime Olefination via Ruthenium Alkylidenes>, Safety of But-3-en-1-ol, the main research area is imine olefine ruthenium alkylidine catalyst olefination; olefin preparation; Alkylidenes; Hydrazones; Olefination; Oximes; Ruthenium.

The development of an efficient method for the olefination of hydrazones and oximes was described. The key design approach that enabled this transformation was tuning of the energy/polarity of C=N π-bonds by employing heteroatom functionalities (NR2, OR). The resulting hydrazones or oximes facilitated olefination with ruthenium alkylidenes. Through this approach, showed that air-stable, com. available ruthenium alkylidenes provide access to functionalized alkenes (20 examples) in ring-closing reactions with yields up to 88%.

Zhan, Ying; Zhao, Yao; Du, Qiang; Rui, Jiacheng; Chen, Rizhi; Zheng, Xintao; Wu, Xiaojin published the artcile< Chemo- and regioselective nucleophilic hydrofunctionalization of unactivated aliphatic alkenes under transition-metal-free catalysts>, Quality Control of 627-27-0, the main research area is beta hetero aliphatic amide preparation green chem chemoselective regioselective; unactivated terminal internal aliphatic alkene nucleophilic Markovnikov selective hydrofunctionalization.

Transition-metal-free-catalyzed nucleophilic hydrofunctionalization of both terminal and internal unactivated aliphatic alkenes has been described for the first time. Most topical classes of carbon, nitrogen and oxygen nucleophiles are well-compatible. The highly chemoselective unprotected dinucleophiles are also presented in the atom-economical approach. More than 80 structurally complex β-hetero-substituted aliphatic amides were rapidly synthesized in good yield with exclusive Markovnikov selectivity, which are difficult to be achieved efficiently by the traditional Michael addition of conjugated amides due to their poor intrinsic electrophilicity.
