M-2 muscarinic acetylcholine receptor (M2R) is a prototypical G protein-coupled receptor (GPCR) that responds to acetylcholine and mediates various cellular responses in the nervous system. Here, we used attenuated total reflection-Fourier transform infrared spectroscopy analyses on M2R reconstituted in a lipid membrane to understand the molecular mechanism behind the ligand binding-induced conformational changes. Upon agonist binding, M2R shows large spectral change of the amide-I band corresponding to backbone C=O stretch, which likely connects with the receptor activation in the lipid environment. These results pave the way to probe effects of different ligand binding on GPCRs using vibrational spectroscopy.

Sinapic acid (SNP) is a nutraceutical compound of hydroxybenzoic acid derivative which possesses antioxidant, anti-microbial, anti-inflammatory, anti-cancer, and anti-anxiety activity properties. In the present work, two cocrystals of SNP with two active drug ingredients such as Ethenzamide (ETZ) and 2-chloro-4-nitrobenzoic acid (CNB) are reported. Both the cocrystals were synthesized via simple solvent evaporation method and the crystal structures were characterized by Single Crystal X-ray Diffraction (SC-XRD) techniques. The cocrystals were formed via robust acid-amide heterosynthon and acid acid homosynthon between SNP and drug molecules. Both the cocrystals were crystallized in monoclinic crystal system with P 2(1)/c space group. The synthesized cocrystals were further characterized by DSC, PXRD, FT-IR, and H-1 NMR techniques. The solubility study in purified distilled water and in 0.1 N HCI solution demonstrate that there was no increment in the solubility of drug molecules in the cocrystals in both purified water and in 0.1 N HCl solution. The synthesized cocrystal exhibited six months stability at ambient conditions (similar to 25 degrees C, 60-65% RH). (C) 2018 Elsevier B.V. All rights reserved.

Waxy crude oil containing large amounts of paraffins often results in various difficulties in extraction and transportation, especially at low temperature. Comb-type copolymers with phenyl pendants were found to be able to improve the flow ability of waxy oils effectively. To investigate the influence of spacer length between phenyl pendant and polymer backbone in comb copolymers on the flow ability of waxy oil, poly(alpha-octadecene-co-maleic acid phenyl alkyl amide)s with various spacer lengths were synthesized by modification of poly(alpha-octadecene-co-maleic anhydride) with aniline, phenethylamine, phentermine, and phenyl-undecanoicamide. Their effects on the morphology and crystallization of model and crude oils were observed by polarized light microscopy and DSC. The flow ability of both oils in the presence of copolymers was studied by means of rheology, including measuring yield stress, viscosity, and thixotropic properties. It is found that the spacer length remarkably affects the rheology and wax crystallization behaviors for both oils. The copolymer with a longer spacer can provide better flexibility of phenyl pendants to disperse asphaltenes more effectively, and the long spacer can cocrystallize with long-chain paraffins.

The present work describes a highly efficient synthetic strategy for amides via oxidative coupling of benzaldehydes or benzylamines with N-substituted formamides using a heterogeneous Co/Al hydrotalcite-derived catalyst in the presence of TBHP. A series of Co/Al hydrotalcite-derived catalysts (Cat-2, Cat-3, and Cat-4 with the Co2+/Al3+ molar ratio in the synthesis mixture as 1/1, 2/1 and 3/1) have been prepared by a simple co-precipitation method and characterized using powder XRD, XPS, FEG-SEM, EDS, FT-IR, DTG-TGA and N-2 physical adsorption techniques. Among the as-prepared catalysts, Cat-3 exhibited excellent catalytic activity towards the direct amidation of benzaldehydes as well as benzylamines bearing various substituents into the corresponding amides at 100 degrees C using TBHP as an oxidant. The mechanistic investigation of the amidation reaction revealed that the reaction follows a radical pathway. Furthermore, the catalyst is easily separable and recyclable without considerable loss in catalytic activity.

The properties of gelatin oven dried at three different temperatures from unicorn leatherjacket (L50, L60 and L70) and reef cod skin (R50, R60 and R70) were investigated. The gelatin yield was higher in unicorn leatherjacket skin (12.2%) than reef cod skin (9.8%). Unicorn leatherjacket skin gelatin had a higher protein content of 88.0-88.61%, lower moisture (9.51-9.91%), fat (0.18-0.29%) and ash (0.60-0.71%) compared to reef cod skin gelatin which had 87-87.73% protein, 10.29-11.03% moisture, 0.23-0.31% fat and 0.69-0.73% ash. SDS-PAGE revealed all the gelatin samples had alpha and beta chains. Gelatin samples had a good proportion of imino acid, hydrophobic and essential amino acid. Fourier transform infrared (FTIR) spectra showed the presence of amide regions in all the samples. Differential scanning calorimetry (DSC) showed a higher melting temperature in unicorn leatherjacket skin gelatin (115.54-120.80 degrees C) than reef cod skin (106.25-118.92 degrees C). Foaming capacity and stability and emulsion stability were higher in unicorn leatherjacket skin gelatin. Emulsion activity index, fat binding and water holding capacities were higher in reef cod skin gelatin. Different oven drying temperatures has not affect the yield and quality of gelatin. This study could pave the way to utilize oven drying for the extraction of gelatin from fish skin.

Ultrafast 2D-IR spectroscopy is a powerful tool for understanding the spectroscopy and dynamics of biological molecules in the solution phase. A number of recent studies have begun to explore the utility of the information-rich 2D-IR spectra for analytical applications. Here, we report the application of ultrafast 2D-IR spectroscopy for the detection and classification of bacterial spores. 2D-IR spectra of Bacillus atrophaeus and Bacillus thuringiensis spores as dry films on CaF2 windows were obtained. The sporulated nature of the bacteria was confirmed using 2D-IR diagonal and off-diagonal peaks arising from the calcium dipicolinate CaDP3H(2)O biomarker for sporulation. Distinctive peaks, in the protein amide I region of the spectrum were used to differentiate the two types of spore. The identified marker modes demonstrate the potential for the use of 2D-IR methods as a direct means of spore classification. We discuss these new results in perspective with the current state of analytical 2D-IR measurements, showing that the potential exists to apply 2D-IR spectroscopy to detect the spores on surfaces and in suspensions as well as in dry films. The results demonstrate how applying 2D-IR screening methodologies to spores would enable the creation of a library of spectra for classification purposes. (C) 2020 Elsevier B.V.

Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter.56-84-8, Name is H-Asp-OH, SMILES is N[C@@H](CC(O)=O)C(O)=O, belongs to amides-buliding-blocks compound.

The purpose of this study was to investigate the potential of immobilized lead- and cadmium-resistant Pseudomonas putida strain PT to remove heavy metals from aqueous medium under extreme conditions. The tolerance and accumulation of cadmium and lead ions by strain PT were investigated by minimal inhibitory concentration (MIC) determination and polymerase chain reaction (PCR) of cadA gene, respectively. The surface chemical functional groups of P. putida PT involved in the metal biosorption were identified by Fourier transform infrared (FTIR). Pseudomonas putida PT was immobilized in three matrices include carboxy-methyl cellulose (CMC), rice bran, and a new composite made of alginate, polyvinyl alcohol (PVA), and CaCO3 to prepare heavy metal adsorbent. The biosorbents were analyzed by SEM, and their metal removal capability was assayed in two consecutive cycles by atomic absorption spectroscopy. The viability of immobilized bacterial cells was determined by flow cytometry during storage at 4 degrees C and exposure to the environmental stresses (pH and temperature). The results showed that PT strain was resistant up to 10mM Pb2+ and 8mM Cd2+. FTIR analysis revealed that alcohol, sulfur, phosphate, esters, and amide groups played important roles in metal biosorption process and, also change in metabolic reactions like hydration and polyesters accumulation was observed after metal biosorption. The presence of cadA gene, a heavy metal translocating pump-coding gene, indicated the ability of metals bioaccumulation by the PT strain. Immobilized cells in alginate-PVA-CaCO3 and rice bran showed the highest metal removal efficiency for Pb2+ as 75% and Cd2+ as 96.7%, respectively. Metal adsorbents were reusable, and the highest removal efficiency in the second cycle was observed in inoculated alginate-PVA-CaCO3 (79.5% Pb2+ and 45% Cd2+). Flow cytometric analysis represented that the immobilized cell viability was retained (<97%) after 4weeks storage at 4 degrees C. Viability under two environmental stresses in all matrices was as follows: <96% at 25 degrees C, <87% at 45 degrees C, <85% at pH4,<96% at pH7, and<89% at pH11. The results signify that these metal adsorbents are efficient technological tools for bioremediation even in harsh environmental conditions. The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant.

Herein, we describe a high yielding approach towards the synthesis of 3-amino-indoles and -benzofurans through 6 pi-electrocyclization. This was made possible by taking advantage of the high reactivity of keteniminium salts, formed in-situ by treating with triflic anhydride and 2-fluoropyridine amides bearing at the alpha-position either an aniline or a phenoxy moiety. These mild conditions, on top of furnishing rapidly the 3-aminobenzoheteroles, allow the tolerance of various functional groups. Control experiments were carried out to highlight that the keteniminium is, indeed, in most cases, the reactive intermediate and conformational preferences of such species were investigated through a DFT study.

The reaction of [(Me3Si)(2)N-Ae{mu-N(SiMe3)(2)}](2) with 2,2,5,5-tetramethyltetrahydrofuran in pentane yields the mononuclear complexes [(Me(4)thf)Ae{N(SiMe3)(2)}(2)] (Ae = Mg (1), Ca (2), Sr (3), and Ba (4)) with three-coordinate alkaline-earth metal centers. With increasing radius of the alkaline-earth metal atoms, the N-Ae-N bond angles decrease. These ether adducts significantly enhance the solubility of the bis(trimethylsilyl)amides of the alkaline-earth metals in hydrocarbon solvents. Contrary to the magnesium derivative 1, the heavier congeners dissociate into mononuclear [Ae{N(SiMe3)(2)}(2)] and free Me4THF without formation of sparingly soluble dinuclear [(Me3Si)(2)N-Ae{mu-N(SiMe3)(2)}](2).
