Margaoan, Rodica published the artcileMonofloral Honeys as a Potential Source of Natural Antioxidants, Minerals and Medicine, Recommanded Product: 4-Methoxyphenylacetic acid, the main research area is review monofloral honey natural antioxidant mineral medicine; anticancer; antioxidant activity; monofloral honey; phenolic compounds; physicochemical properties.

Background: vegetative diversity is based on different climate and geog. origins. In terms of beekeeping, herbal diversity is strongly correlated to the production of a wide variety of honey. Therefore, based on the existing plant diversity in each country, multiple honey varieties are produced with different health characteristics. While beekeeping potential and consumption preferences are reflected in productsâ€?variety, this leads to an increase in the region′s economy and extensive export. In the last years, monofloral honey has gained interest from consumers and especially in the medicinal field due to the presence of phytochems. which are directly linked to health benefits, wound healing, antioxidant, anticancer and anti-inflammatory activities. Scope and approach: this review aims to highlight the physicochem. properties, mineral profiles and antioxidant activities of selected monofloral honeys based on their botanical and geog. origin. Moreover, this review focuses on the intercorrelation between monofloral honey′s antioxidant compounds and in vitro and in vivo activities, focusing on the apoptosis and cell proliferation inhibition in various cell lines, with a final usage of honey as a potential therapeutic product in the fight towards reducing tumor growth. Key findings and conclusions: multiple studies have demonstrated that monofloral honeys have different physicochem. structures and bioactive compounds Useful chem. markers to distinguish between monofloral honeys were evidenced, such as: 2-methoxybenzoic acid and trimethoxybenzoic acid are distinctive to Manuka honey while 4-methoxyphenylacetic acid is characteristic to Kanuka honey. Furthermore, resveratrol, epigallocatechin and pinostrobin are markers distinct to Sage honey, whereas carvacrol and thymol are found in Ziziphus honey. Due to their polyphenolic profile, monofloral honeys have significant antioxidant activity, as well as antidiabetic, antimicrobial and anticancer activities. It was demonstrated that Pine honey decreased the MDA and TBARS levels in liver, kidney, heart and brain tissues, whereas Malicia honey reduced the low-d. lipoprotein level. Consumption of Clover, Acacia and Gelam honeys reduced the weight and adiposity, as well as trygliceride levels. Furthermore, the antiproliferative effect of chrysin, a natural flavone in Acacia honey, was demonstrated in human (A375) and murine (B16-F1) melanoma cell lines, whereas caffeic acid, a phenolic compound found in Kelulut honey, proves to be significant candidate in the chemoprevention of colon cancer. Based on these features, the use of hiney in the medicinal field (apitherapy), and the widespread usage of natural product consumption, is gaining interest by each year.

Lori, G. published the artcileHoney extracts inhibit PTP1B, upregulate insulin receptor expression, and enhance glucose uptake in human HepG2 cells, Synthetic Route of 104-01-8, the main research area is heaptocellular carcinoma glycemic honey PTP1B insulin receptor glucose; Insulin signaling; Phenolic compounds; Protein-tyrosine phosphatase 1B; Tuscany honey; Type 2 diabetes.

Honey is a food known for its medical properties. In this work, we have studied the impact of different types of honey on insulin signalling pathway. We found that honey extracts inhibit the enzyme PTP1B, one of the main neg. regulators of insulin receptor signalling. HPLC-MS anal. allowed us to confirm the presence of several natural PTP1B inhibitors in the honey extracts analyzed. Statistical anal. methods show a correlation between specific 1H-NMR resonance frequencies/HPLC peaks and the inhibitory power of the samples. This finding will allow the prediction of the biol. properties of honey samples applying relative simple anal. methods. Finally, we demonstrated that the treatment of HepG2 cells with honey extracts enhances the expression of insulin receptor, and stimulates glucose uptake. For the first time, our results demonstrate that bioactive components of honey could improve glycemic control by both inhibiting PTP1B and stimulating the expression of insulin receptor in liver cells.

Xie, Xiaoyu published the artcileIn-depth profiling of carboxyl compounds in Chinese Baijiu based on chemical derivatization and ultrahigh-performance liquid chromatography coupled to high-resolution mass spectrometry, Product Details of C9H10O3, the main research area is Chinese Baijiu carboxyl compound chem derivatization UHPLC HRMS; Carboxyl compounds; Chemical derivatization; Chinese Baijiu; High-coverage analysis; High-resolution mass spectrometry.

Carboxyl compounds have a significant influence on the flavor of Chinese Baijiu. However, because of the structural diversity and low concentration, the deep profiling of carboxyl compounds in Chinese Baijiu is still challenging. In this work, a systematic method for comprehensive anal. of carboxyl compounds in Chinese Baijiu was established. After derivatized under optimized conditions, 197 p-dimethylaminophenacyl bromide-derived carboxylic compounds were annotated by multidimensional information including accurate mass, predicted tR, in-silico MS/MS, and diagnostic ions for the first time. In addition, 48 of the 197 carboxyl compounds were pos. identified, and three of them were newly identified in Chinese Baijiu. Moreover, we found the number and the concentration of carboxyl compounds in sauce-flavor Baijiu were more abundant than in strong-flavor Baijiu. This work provides a novel method for the anal. of carboxyl compounds in Baijiu and other complex samples.

DiRico, Kenneth J. published the artcileUltra-High-Throughput Acoustic Droplet Ejection-Open Port Interface-Mass Spectrometry for Parallel Medicinal Chemistry, HPLC of Formula: 104-01-8, the main research area is preparation high throughput mass spectrometry.

High-throughput experimentation (HTE) has emerged as an important tool in drug discovery, providing a platform for preparing large compound libraries and enabling swift reaction screening over wide-ranging conditions. Recent advances in automated high-d., material-sparing HTE have necessitated the development of rapid analytics with sensitivity and resolution sufficient to identify products and/or assess reaction performance in a timely and data-rich manner. Combination of an ultra-throughput (UT) reader platform with Acoustic Droplet Ejection-Open Port Interface-Mass Spectrometry (ADE-OPI-MS) provides the requisite speed and sensitivity. Herein, the authors report the application of ADE-OPI-MS to HTE in the areas of parallel medicinal chem. and reaction screening.

Tassone, Emmanuel A. published the artcileNumerical evolution of the center of mass and angular momentum for binary black holes, Category: isoquinoline, the main research area is center of mass angular momentum.

The asymptotic approach derived by Kozameh-Quiroga provides a modern framework to obtain the evolution of global variables of isolated sources of gravitational radiation. We test the Kozameh-Quiroga formalism evolving the equations of motion for the center of mass, the intrinsic angular momentum, and several other global variables, for black hole binary coalescence. First, we evolve the equations of motion using 777 simulations from the RIT catalog of numerical data of ψ4 [J. Healy and C. O. Lousto, Third RIT binary black hole simulations catalog, Phys. Rev. D102, 104018 (2020).PRVDAQ2470-001010.1103/PhysRevD.102.104018]. We then analyze the trajectory of the center of mass and compute the final state of other phys. variables after the coalescence has taken place. Finally, we show that the results obtained from our equations of motion are consistent with those in the Rochester metadata.

Kumar, Naresh published the artcileTuning of optical properties of p-phenyl ethenyl-E-furans: A Solvatochromism and Density functional theory, Product Details of C9H10O3, the main research area is phenylethenyl furan preparation optical electronic property substituent effect; Absorption; Density functional theory; Dipole moment; Fluorescence; Hyperpolarizability; Oscillator strength; Polarizability; Transition dipole moment.

P-Ph ethenyl-E-furans (1-6) with varied electron donor and acceptor substituent (NO2, CN, Cl, H, OCH3, NH2) were synthesized and studied the substituent induced optical properties (dipole moment, transition dipole moment, oscillator strength, optical band gap, hyperpolarizability) using Solvatochromism and D. functional theory. It is shown that furan acts as a weak electron donor in presence of an electron withdrawing p-Ph substituent (NO2, CN, Cl), whereas furan acts as a weak electron acceptor in presence of an electron donating p-Ph substituent (OCH3, NH2). In comparison to ethenylfuran 4, the HOMO-LUMO energy band gap is decreased upon increasing the electron donating or electron withdrawing nature of the Ph ring. Calculation of excited state dipole moment and polarizability of 1-6 in solvent of varying polarity suggest that the nitro and amino compounds (1, 6) exhibit charge transfer excited state, whereas excited state of compounds 3-5 is non-polar in nature. As compared to the ethenylfuran (4), the first hyperpolarizability (β) is increased in presence of a strong electron withdrawing or strong electron donating p-Ph substituent. The higher β value is found for ethenylfuran with p-nitrophenyl and p-amino Ph substitution. Overall, these studies provide useful information in tuning the optical properties of p-Ph substituted heterocyclic ethenyl systems.
