Water-soluble vitamins like B3 (nicotinamide), B6 (pyridoxine), and B9 (folic acid) are of utmost importance in human health and disease, as they are involved in numerous critical metabolic reactions. Not surprisingly, deficiencies of these vitamins have been linked to various disease states. Unfortunately, not much is known about the physiological levels of B6 vitamers and vitamin B3 in an ethnically isolated group (such as an Emirati population), as well as their relationship with obesity. The aim of the present study was to quantify various B6 vitamers, as well as B3, in the plasma of obese and healthy Emirati populations and to examine their correlation with obesity. A sensitive and robust HPLC-MS/MS-based method was developed for the simultaneous quantitation of five physiologically relevant forms of vitamin B6, namely pyridoxal, pyridoxine, pyridoxamine, pyridoxamine phosphate, and pyridoxal phosphate, as well as nicotinamide, in human plasma. This method was used to quantify the concentrations of these vitamers in the plasma of 57 healthy and 57 obese Emirati volunteers. Our analysis showed that the plasma concentrations of nicotinamide, pyridoxal, and pyridoxamine phosphate in the obese Emirati population were significantly higher than those in healthy volunteers (p< 0.0001,p= 0.0006, andp= 0.002, respectively). No significant differences were observed for the plasma concentrations of pyridoxine and pyridoxal phosphate. Furthermore, the concentrations of some of these vitamers in healthy Emirati volunteers were significantly different than those published in the literature for Western populations, such as American and European volunteers. This initial study underscores the need to quantify micronutrients in distinct ethnic groups, as well as people suffering from chronic metabolic disorders. COA of Formula: C8H10ClNO3.

Recently I am researching about SELECTIVE OXIDATION; ALPHA-OXYGENATION; FREE CATALYST; AMIDES, Saw an article supported by the Fonds der Chemischen Industrie (FCI, Liebig-Fellowship); Chinese Scholarship Council (CSC)China Scholarship Council.

This protocol describes the use of 9-fluorenone as a cheap and non-toxic photocatalyst for the oxidation of non-activated alcohols performed under the irradiation of a blue light-emitting diode. It also describes the use of the similarly cheap and non-toxic photocatalyst rose bengal for the selective alpha-oxygenation of tertiary amines to produce the corresponding amides in a selective way using the same light source. We have provided detailed instructions on how to assemble the light-emitting diode equipment and set up the photocatalytic reaction, where an oxygen atmosphere is created with an O-2-filled balloon. Further details are provided using four example reactions that illustrate how this system works: alcohol oxidation to prepare terephthlalaldehyde and androstanedione, and amine oxidation to make 2-phenyl-3,4-dihydroisoquinolin-1(2H)-one and (4-((4-chlorophenyl)(phenyl)methyl)piperazin-1-yl)m-tolyl)methanone. The times needed to perform these photocatalytic reactions are 18, 76, 22 and 54 h, respectively. We believe that this protocol represents a robust methodology for the late-stage modification of amines and the selective oxidation of steroids. Cheap and non-toxic photocatalysts 9-fluorenone or rose bengal are used to oxidize non-activated alcohols or oxygenate tertiary amines, respectively, under irradiation from a blue light-emitting diode.

Two neutral pentacoordinate mononuclear cadmium(II) complexes of the type [Cd(L)X-2] [L = N-(pyridin-2′-yl)benzylidene)-2-(piperidin-1-yl)ethane-1,2-diamine; X = Cl, (1) and X = Br, (2)], one neutral hexacoordinate dinuclear compound [Cd(L)(mu-NCS)NCS](2) (3) and one neutral hexacoordinate coordination polymer [Cd(L)(mu-N-3)N-3](n) (4) have been prepared and characterized using microanalytical, spectroscopic, thermal and X-ray crystallographic results. Structural analyses show that each cadmium(II) center in the isostructural compounds 1 and 2 adopts a distorted square pyramidal geometry with a CdN3X2 [X = Cl in 1 and X = Br in 2] chromophore through coordination of three N atoms of L and two terminal halides. In 3 and 4, each metal(II) center affords a distorted octahedral geometry with MN5S (in 3) and MN6 (in 4) chromophores. Each metal(II) center in dinuclear compound 3 is attached to three N-atoms of L, one N-atom of terminal thiocyanate, and one N-atom and one S-atom of two mu(1,3)-bridging thiocyanate units, whereas three N-atoms of L and three N-atoms of one terminal and two mu(1,3)-bridging azide units are bound to each metal(II) center in the coordination polymer 4. Each metal (II) center in 4 is connected to two other metal(II) centers through two different mu(1,3)-azide bridges affording a zigzag one-dimensional (1D) chain. In the crystalline state, mononuclear units in both 1 and 2 are stabilized through intermolecular C-H center dot center dot center dot X (X = Cl in 1 and X = Br in 2) hydrogen bonds promoting to 2D sheet structures. The dinuclear units in 3 pack through cooperative intermolecular C-H center dot center dot center dot S and C-H center dot center dot center dot N hydrogen bonds giving rise to a 3D network structure. 1D chains in 4 are stabilized through cooperative intermolecular C-H center dot center dot center dot N hydrogen bonds promoting to a 2D sheet structure. These 2D sheets, in turn, self-assemble through weak noncovalent pi center dot center dot center dot pi interactions to afford a 3D network structure. The thermally stable compounds (1-4) exhibit intraligand (1)(pi-pi*) fluorescence in DMF solutions at room temperature with lifetimes in range 0.83-2.94 ns.

Human 15-lipoxygenase-1 (15-LOX-1) belongs to the class of lipoxygenases, which catalyze oxygenation of polyunsaturated fatty acids, such as arachidonic and linoleic acid. Recent studies have shown that 15-LOX-1 plays an important role in physiological processes linked to several diseases such as airway inflammation disease, coronary artery disease, and several types of cancer such as rectal, colon, breast and prostate cancer. In this study, we aimed to extend the structural diversity of 15-LOX-1 inhibitors, starting from the recently identified indolyl core. In order to find new scaffolds, we employed a combinatorial approach using various aromatic aldehydes and an aliphatic hydrazide tail. This scaffold-hopping study resulted in the identification of the 3-pyridylring as a suitable replacement of the indolyl core with an inhibitory activity in the micromolar range (IC50=16 +/- 6m) and a rapid and efficient structure-activity relationship investigation.

We develop the chemistry of boron difluoride hydrazone dyes (BODIHYs) bearing two aryl substituents and explore their properties. The low-energy absorption bands (lambda(max)=427-464 nm) of these dyes depend on the nature of the N-aryl groups appended to the BODIHY framework. Electron-donating and extended pi-conjugated groups cause a redshift, whereas electron-withdrawing groups result in a blueshift. The title compounds were weakly photoluminescent in solution and strongly photoluminescent as thin films (lambda(PL)=525-578 nm) with quantum yields of up to 18 % and lifetimes of 1.1-1.7 ns, consistent with the dominant radiative decay through fluorescence. Addition of water to THF solutions of the BODIHYs studied causes molecular aggregation which restricts intramolecular motion and thereby enhances photoluminescence. The observed photoluminescence of BODIHY thin films is likely facilitated by a similar molecular packing effect. Finally, cyclic voltammetry studies confirmed that BODIHY derivatives bearing para-substituted N-aryl groups could be reversibly oxidized (E-ox1=0.62-1.02 V vs. Fc/Fc(+)) to their radical cation forms. Chemical oxidation studies confirmed that para-substituents at the N-aryl groups are required to circumvent radical decomposition pathways. Our findings provide new opportunities and guiding principles for the design of sought-after multifunctional boron difluoride complexes that are photoluminescent in the solid state.

Oguro, Y; Nakamura, A; Kurahashi, A in [Oguro, Yoshifumi; Nakamura, Ayana; Kurahashi, Atsushi] Hakkaisan Brewery Co Ltd, 1051 Nagamori, Minamiuonuma, Niigata 9497112, Japan published Effect of temperature on saccharification and oligosaccharide production efficiency in koji amazake in 2019.0, Cited 22.0.

Koji amazake, prepared from rice koji, is a traditional Japanese sweet beverage. The main source of sweetness is glucose derived from rice starch following digestion by enzymes of Aspergillus oryzae during saccharification. The temperature of this process was empirically determined as 45 degrees C-60 degrees C, but no studies have systematically investigated the effect of temperature on saccharification efficiency. We addressed this in the present study by evaluating saccharification efficiency at various temperatures. We found that glucose content was the highest at 50 degrees C (100%) and was reduced at temperatures of 40 degrees C (66.4%), 60 degrees C (91.9%), and 70 degrees C (76.6%). We previously reported that 12 types of oligosaccharides are present in koji amazake; the levels of eight of these, namely nigerose, kojibiose, trehalose, isomaltose, gentiobiose, raffinose, panose, and isomaltotriose, were the highest at 50 degrees C-60 degrees C, whereas sophorose production was maximal at 70 degrees C. Based on these findings, we initially performed saccharification at 50 degrees C and then switched the temperature to 70 degrees C. The maximum amount of each saccharide including sophorose that was produced was close to the values obtained at these two temperatures. Thus, oligosaccharide composition of koji amazake is dependent on saccharification temperature. These findings provide useful information for improving the consumer appeal of koji amazake by enhancing oligosaccharide content. (C) 2018, The Society for Biotechnology, Japan. All rights reserved.

Efficient access to diverse screening compounds with desirable, lead-like properties can be a bottleneck in early drug discovery and chemical biology. Herein we present an efficient, rapid route to three structurally distinct classes of compounds (A-C) from a single precursor, which in turn is available through a one-pot Petasis 3-component reaction/Diels-Alder cascade reaction. We demonstrate the versatility of the approach through the synthesis of 35 exemplary compounds from the three classes, as well as by the production of 2188 final compounds, which have been included in the Joint European Compound Library of the European Lead Factory.

Oxidized products have become increasingly valuable as building blocks for a wide variety of different processes and fine chemistry, especially in the benzylic position. We report herein a sustainable protocol for this transformation through C-H functionalization and is performed using electrochemistry as the main power source and tert-butyl hydroperoxide as the radical source for the C-H abstraction. The temperature conditions reported here do not increase above 50 degrees C and use an aqueous-based medium. A broad substrate scope is explored, along with bioactive molecules, to give comparable and increased product yields when compared to prior reported literature without the use of electrochemistry.
