Herein, we report a graphene oxide (GO) catalyzed condensation of non-activated esters and amines, that can enable diverse amides to be synthesized from abundant ethyl esters forming only volatile alcohol as a by-product. GO accelerates ester to amide conversion in the absence of any additives, unlike other catalysts. A wide range of ester and amine substrates are screened to yield the respective amides in good to excellent yields. The improved catalytic activity can be ascribed to the oxygenated functionalities present on the graphene oxide surface which forms H-bonding with the reactants accelerating the reaction. Improved yields and a wide range of functional group tolerance are some of the important features of the developed protocol.

A catalyst-free, base-mediated N- sec -alkylation of amides by reaction of sulfonylindoles and -halohydroxamates has been developed. The N- sec -alkylation of amides reaction is based on an intermolecular nucleophilic addition of vinylogous imine with N -(benzyloxy)meth-acrylamide/azaoxyallyl cations formed in situ and represents a simple way to give polyfunctionalized 3-indolyl methanamines in good to excellent yields.

Sufu is a pleasant-tasting, traditional Chinese fermented soybean food that is rich in nutrients. In this study, the changes of volatile and nonvolatile metabolites in sufu fermented by bacillus licheniformis, were investigated. The results indicated that a total of 55 kinds of nonvolatile compounds were detected, including 2 carbohydrates, 4 alcohols, 17 amino acids, 18 organic acids, 6 biogenic amines, and 8 other substances. Furthermore, a total of 58 volatile compounds identified were composed of 11 esters, 16 alcohols, 10 acids, and 21 miscellaneous compounds. Inoculation of bacillus licheniformis enriched the metabolite pro?le of sufu and improved its functionality and safety of edibility. It was observed that the pure fermented starter resulted in controlled acceleration of sufu maturation.

I found the field of Biochemistry & Molecular Biology; Chemistry very interesting. Saw the article Significantly Elevated Levels of Plasma Nicotinamide, Pyridoxal, and Pyridoxamine Phosphate Levels in Obese Emirati Population: A Cross-Sectional Study published in 2020.0.

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. SDS of cas: 65-22-5.

A new three-component strategy from aldehyde, p-toluenesulfonyl hydrazide and potassium thiocyanate for the synthesis of 2-aminothiadiazoles promoted by I-2 under metal-free conditions has been described. Potassium thiocyanate was used as an odorless and low-toxicity sulfur source. A wide range of aromatic aldehydes can smoothly undergo the three-component cyclization reaction under the optimized conditions to give the corresponding products in moderate to good yields.

I found the field of Spectroscopy very interesting. Saw the article Study on the interaction between pyridoxal and CopC by multi-spectroscopy and docking methods published in 2019.0.

The interaction between pyridoxal hydrochloride (HQ) and apoCopC was investigated using Fourier transform infrared spectroscopy (FTIR), isothermal titration calorimetry (ITC), circular dichroism (CD), fluorescence spectroscopy, three-dimensional (3D) fluorescence spectroscopy, fluorescence lifetime, TNS fluorescence and docking methods. FTIR, CD, TNS fluorescence and fluorescence lifetime experiments suggested that the apoCopC conformation was altered by HQ with an increase in the random coil content and a reduction in the beta-sheet content. In addition, the data from fluorescence spectroscopy, 3D fluorescence spectroscopy and molecular docking revealed that the binding site of HQ was located in the hydrophobic area of apoCopC, and a redshift of the HQ fluorescence spectra was observed. Furthermore, ITC and fluorescence quenching data manifested that the binding ratio of HQ and apoCopC was 1:1, and the forming constant was calculated to be (7.06 +/- 0.21) x 10(5) M-1. The thermodynamic parameters Delta H and Delta S suggested that the formation of a CopC-HQcomplex depended on the hydrophobic force. Furthermore, the average binding distance between tryptophan in apoCopC and HQ was determined by means of Forster non-radioactive resonance energy transfer and molecular docking. The results agreed well with each other. As a redox switch in the modulation of copper, the interaction of apoCopC with small molecules will affect the action of the redox switch. These findings could provide useful information to illustrate the copper regulation mechanism. (C) 2018 Elsevier B.V. All rights reserved.

Two series of saccharin/isoxazole and saccharin/isoxazoline hybrids were synthesized by 1,3-dipolar cycloaddition. The new compounds showed to be endowed with potent and selective inhibitory activity against the cancer-related human carbonic anhydrase (hCA) IX and XII isoforms in the nanomolar range, while no affinity was encountered for off-targets, such as hCA I and II. Successive enantioseparation on a milligram scale of the most representative compounds led to the discovery that (S)-isomers were more potent than their corresponding (R)-enantiomers. Lastly, molecular modeling studies were conducted to define those structural requirements that were responsible for the discrimination among selected human isoforms of carbonic anhydrases. Two nanomolar hCA IX and XII inhibitors were also screened for their selective toxicity against non tumoral primary cells (fibroblasts) and against a breast adenocarcinoma cell line (MCF7) in hypoxic environment. The efficacious combination of these compounds with doxorubicin on MCF7 cells was demonstrated after 72 h of treatment.
