A chemical sensor composed of pyridoxal hydrochloride schiff base based on diarylethene (1O) was synthesized. Its photochemical properties and selectivity to ions were further studied. The chemosensor could detect cyanide effectively and is almost undisturbed by other ions. When titrating CN-, the reaction aroused a distinct change in the absorption spectrum with the color change from transparent to yellow, and the fluorescence intensity centered at 562 nm was increased 68 folds. It also exhibited a good fluorescence sensing of Mg(2+ )with high selectivity and sensitivity. Upon addition of Mg2+, its emission intensity enhanced 110 folds, with the color change from dark to bright blue. Its good spectral response could be applied to molecular logic circuit. Moreover, the chemosensor could be made into test paper strips for the qualitative and quantitative detection of CN- and Mg2+.

Purpose: We investigated Nw-hydroxy L-Arginine (NOHA) predictive response in serous ovarian carcinoma based on estrogen-hormone receptor expression status; and assessed the distinctive NOHA response between estrogen-receptor-negative (ER-) tumor subtypes of ovarian and breast cancer. Materials/methods: Three-dimensional (3D) spheroids models of ER- and estrogen-receptor-positive (ER+) from breast and ovarian tumor, cultured for 9 weeks, were assayed for cellular levels of inducible nitric oxide synthase (NOS2), nitric oxide (as total nitrite) and L-Arginine, and compared to NOHA in culture medium. Statistical difference was set at p < 0.01. Results: Nine-week in vitro studies showed a progressive NOHA reduction in culture medium by at least 0.4-0.8 fold, and 0.65-0.92 fold only in the ER-breast tumor and ER-ovarian tumor 3D spheroids, respectively; with increases in cellular NOS2 and nitric-oxide levels, by at least 1.0-2.45 fold in both ER-tumor subtype 3D spheroids (p < 0.01; n = 6). Within ER-subtypes, medium NOHA decreased by >= 38.9% in ovarian cancer over breast cancer 3D-spheroids, with cellular increases in NOS2 (by >= 17.4%), and nitric oxide (by >= 18.8%). Cellular L-Arginine to medium NOHA ratio was higher, and by at least 6.5-22.5 fold in ER-breast tumor 3D-spheroids, and at least 10-70 fold in ER-ovarian tumor 3D spheroids, than in ER+ and control conditions; and was >= 48% higher in ER-ovarian cancer than in ER-breast cancer 3D-spheroids. Conclusions: The present study shows NOHA as a sensitive and selective indicator differentiating and distinguishing ER-subtypes based on the tumor grade.

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.

A naphthalimide-pyridoxal conjugate 1 has been designed and synthesized. Compound 1 forms a stable greenish yellow colored gel in DMSO:H2O (8:1 v/v). Rheological study reveals that the gel is mechanically strong (G> G) over a wide range of applied strains. The morphology of the gel as determined by FESEM shows a highly cross-linked fibrous network. The gel is anion-responsive and is selectively transformed into a sol with a color change from greenish yellow to deep blue only in the presence of F- among other anions. In CH3CN, compound 1 was also sensitive to basic anions such as F- and AcO- ions. In solution, F- was differentiated from AcO- through a color change. While the yellow colored solution of 1 in acetonitrile was changed into deep blue in the presence of F-, AcO- ions gave a faint blue coloration. A similar colorimetric differentiation of F- from AcO- has been possible in CH3CN by a reusable Schiff base-linked Merrifield resin 1a or 1b.

The synthesis and solid state structural, spectral and electrochemical solution characterization of [Cu(L)(acpy)]ClO4 1 and [Cu(L)(NO3)]( )2 [where L = N'[(E)-phenyl(pyridin-2-yl)methylideneithiophene-2-carbohydrazide and acpy = 2,6-Diacetylpyridine] have been done by elemental analysis, UV-vis, FTIR, electrochemical techniques (CV and DPV) and electron paramagnetic resonance (epr) spectroscopy. The single crystal structures were solved by the X-ray diffraction technique. In complex 1, copper ion is in a distorted octahedral environment. The geometry of copper(II) in complex 2 is distorted square pyramidal (tau = 0.201). The mono deprotonated, HL ligand act as a tridentate to a copper(II) ion. On the basis of density functional theory (DFT) calculation, the electronic excitations involve transitions mainly from metal ligand bonding mostly the alpha-LUMO within the dominant Cu d(xy) character and to alpha-LUMO+1. Epr spectra for polycrystalline samples showed the copper(II) hyperfine features as well as half-field signal which are appropriate for Delta M-s = +/- 2 of dimers. Presence of half-field signal in 1 is due to solid-solid interaction (intra-molecular) where as in 2 the nature of interaction is intra-molecular. The antioxidant superoxide measurements show that the both complexes 1 and 2 behave as superoxide mimic in alkaline nitro blue tetrazolium chloride assay. (C) 2020 Elsevier B.V. All rights reserved.

The lack of efficacy of current antibacterials to treat multidrug resistant bacteria poses a life-threatening alarm. In order to develop enhancers of the antibacterial activity, we carried out a medicinal chemistry campaign aiming to develop inhibitors of enzymes that synthesise cysteine and belong to the reductive sulphur assimilation pathway, absent in mammals. Previous studies have provided a novel series of inhibitors for O-acetylsulfhydrylase – a key enzyme involved in cysteine biosynthesis. Despite displaying nanomolar affinity, the most active representative of the series was not able to interfere with bacterial growth, likely due to poor permeability. Therefore, we rationally modified the structure of the hit compound with the aim of promoting their passage through the outer cell membrane porins. The new series was evaluated on the recombinant enzyme from Salmonella enterica serovar Typhimurium, with several compounds able to keep nanomolar binding affinity despite the extent of chemical manipulation.

2-Pyridyl ketones widely appear in bioactive molecules, natural products, and are employed as precursors of chiral 2-pyridine alky/aryl alcohols or 2-aminoalkyl pyridine ligands for asymmetric catalysis. Herein, a practical method for the rapid synthesis of 2-pyridyl ketone library in continuous flow is reported, in which the 2-lithiopyridine formed by Br/Li exchange reacts with commercially available esters to obtain 2-pyridyl ketones in a good yield at short reaction time. This protocol functions broadly on a variety of esters and has been applied to the synthesis of TGF-beta type 1 receptor inhibitor LY580276 intermediate in an environmentally friendly method. It is rapid, reliable, and cost-efficient to afford diverse kinds of 2-pyridyl ketones in the compound library.

In this study, the chemical and sensory profiles of 42 different nonalcoholic beer (NAB) brands/styles already on the global market and produced through several different brewing techniques were evaluated. A trained panel (i.e., 11 panelists) performed standard-driven descriptive and check-all-that-apply analyses in triplicate to sensorially characterize the aroma and taste/mouthfeel profiles of 42 commercial NABs, a commercial soda, and a commercial seltzer water (n = 44). These beers were also chemically deconstructed using several different analytical techniques targeting volatile and nonvolatile compounds. Consumer analysis (n = 129) was then performed to evaluate the Northern Californian consumer hedonic liking of a selection (n = 12) of these NAB brands. These results provide direction to brewers and/or beverage producers on which techniques they should explore to develop desirable NAB offerings and suggest chemical targets that are indicators of specific flavor qualities and/or preference for American consumers.
