Era, Benedetta published the artcileLooking for new xanthine oxidase inhibitors: 3-Phenylcoumarins versus 2-phenylbenzofurans, Application of 4-Methoxyphenylacetic acid, the main research area is gout phenylcoumarin phenylbenzofuran xanthine oxidase inhibitor mol docking; 2-Phenylbenzofurans; 3-Phenylcoumarins; Xanthine oxidase inhibitors.

Overproduction of uric acid in the body leads to hyperuricemia, which is also closely related to gout. Uric acid production can be lowered by xanthine oxidase (XO) inhibitors. Inhibition of XO has also been proposed as a mechanism for improving cardiovascular health. Therefore, the search for new efficient XO inhibitors is an interesting topic in drug discovery. 3-Phenylcoumarins and 2-phenylbenzofurans are privileged scaffolds in medicinal chem. Their structural similarity makes them interesting mols. for a comparative study. Methoxy and nitro substituents were introduced in both scaffolds. The current study gives some insights into the synthesis and biol. activity of these mols. against this important target. For the best compound of the series, the 3-(4-methoxyphenyl)-6-nitrocoumarin (4), the IC50 value, type of inhibition, cytotoxicity on B16F10 cells and ADME theor. properties, were determined Docking studies were also performed in order to better understand the interactions of this mol. with the XO binding pocket. This work is a preliminary screening for further design and synthesis of new non-purinergic derivatives as potential compounds involved in the inflammatory suppression, specially related to gout.

Deus, Lysleine Alves published the artcileHeart rate variability in middle-aged sprint and endurance athletes, COA of Formula: C9H10O3, the main research area is Aging; Athletics; Cardiovascular; Master athletes; Parasympathetic; Running; Sympathetic.

Aging is associated with decreased autonomic balance which could be assessed by Heart Rate Variability (HRV). Exercise training improves autonomic balance, but there is a lack in the literature regarding the heart rate variability (HRV) of master sprinters and endurance athletes. The effects of lifelong endurance and sprint training on cardiac autonomic balance were assessed in master athletes and compared with age-matched controls and young untrained controls. Participants (n = 81) were 8 master sprinters (MS; 51.8 ± 11.1 yrs), 8 master endurance athletes (EN, n = 8, 53.6 ± 8.6 yrs), 17 age-matched untrained (CON, 47.47 ± 6.00 yrs) and 48 young controls (YC, 25.40 ± 3.87 yrs). For the acquisition of RR intervals (iRR) (Polar RS800X Heart Rate Monitor) the participants remained seated for 15-min with the final 10-min being considered for anal. HRV was measured using Kubios software. A one-way ANOVA with repeated measures was applied. All studied parameters did not differ between MS and EN {Time Domain [HR (bpm) 59.00 ± 6.13 vs. 58.94 ± 12.75], [R-R (ms) 1030.45 ± 107.45 vs. 1068.77 ± 206.17], [SDNN (ms) 57.35 ± 20.07 vs. 80.66 ± 71.07], [RMSSD (ms) 40.88 ± 20.07 vs. 38.93 ± 20.44]; Non-linear domain [SD1 (ms) 28.93 ± 14.20 vs. 27.56 ± 14.46]}, whose demonstrated a reduced HR and elevated mean R-R intervals in comparison to both YC {[HR (bpm) 69.64 ± 9.81]; [R-R (ms) 883.93 ± 124.11]} and age-matched controls {[HR (bpm) 70.06 ± 6.63]; [R-R (ms) 865.11 ± 78.39]}. It was observed a lower HRV for middle-aged CON {[RMSSD (ms) 20.23 ± 5.87], [SDNN (ms) 37.79 ± 10.15] and [SD1 (ms) 14.31 ± 4.15]} compared to YC {[RMSSD (ms) 43.33 ± 26.41], [SDNN (ms) 67.07 ± 28.77] and [SD1 (ms) 30.66 ± 18.69; p < .05]}. These last age-related differences were not observed for MS and EN. For master athletes, regardless of whether they are trained in endurance or sprinters, both training modes revealed to be equally beneficial in attenuating the effects of aging on the autonomic balance.

Volatile organic compounds (VOCs) composition of Polish honeys obtained from various geog. regions was studied. Headspace solid phase microextraction (HS-SPME) using Divinylbenzene/Carboxen/Polydimethylsiloxane-coated fibers was used in combination with comprehensive two-dimensional gas chromatog.-time-of-flight mass spectrometry (GC×GC-TOFMS) because of the complexity of the samples. Acacia, linden, rapeseed, buckwheat and honeydew honeys were studied in this project. A total of 329 compounds were identified during the investigations. Pos. identification of 82 compounds was achieved using anal. standards, while tentative identification of 247 compounds was based on comparison of deconvoluted mass spectra and linear temperature programmed retention indexes (LTPRI) with NIST 2005 library and literature values, resp. Many VOCs identified in Polish honey samples were commonly present in honeys from other geog. regions of Europe (e.g. Italy, Corsica). They included certain acyclic and cyclic alkanes, acyclic and cyclic alkenes, aromatic hydrocarbons, oxygenated aromatic compounds, alcs., aldehydes, ketones, esters, ethers, nitriles, organic sulfides, phenolic compounds and terpenes. GC×GC-TOFMS profiles for the same types of honey samples were remarkably similar. Eight botanic discriminants were selected among all compounds Their identity was confirmed by comparison with authentic standards Furthermore, possible geog. discriminants for Polish honeys were identified, including 19 for acacia, 3 for linden, 3 for rapeseed and buckwheat and 6 for honeydew honeys.

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.
