A convenient and practical pathway to versatile silylated amides and anilides is described via efficient and selective ruthenium(ii) catalyzed ortho C-H silylation. Both amides and anilides were successfully silylated with good functional group tolerance and high regioselectivity. Different alkenes as the hydrogen acceptors played a crucial role in these two catalytic systems. Unexpectedly, two pathways for RuHCl(CO)(PPh3)(2)/KOAc catalyzed C-H silylation involving a 5-membered ruthenacycle with arylamides and a 6-membered ruthenacycle with arylanilides, take place depending on the nature of the alkene as the hydrogen trapper.

The catalytic enantioselective synthesis of the chiral key intermediate of the antidepressant (-)-paroxetine is demonstrated as a continuous flow process on multi-gram scale. The critical step is a solvent-free organocatalytic conjugate addition followed by a telescoped reductive amination-lactamization-amide/ester reduction sequence. Due to the efficient heterogeneous catalysts and the solvent-free or highly concentrated conditions applied, the flow method offers key advances in terms of productivity and sustainability compared to earlier batch approaches.

The early stages of Alzheimer’s disease pathogenesis are thought to occur at the synapse level, since synapse loss can be directly correlated with memory dysfunction. Considerable evidence has suggested that amyloid beta (A beta), a secreted proteolytic derivative of amyloid precursor protein, appears to be a critical factor in the early ‘synaptic failure’ that is observed in Alzheimer’s disease pathogenesis. The identification of A beta at neuronal spines with high spatial resolution and high surface specificity would facilitate unraveling the intricate effect of A beta on synapse loss and its effect on neighboring neuronal connections. Here, tip-enhanced Raman spectroscopy was used to map the presence of A beta aggregations in the vicinity of the spines exposed to A beta preformed in vitro. Exposure to A beta was of 1 and 6 hours. The intensity variation of selected vibrational modes of A beta was mapped by TERS for different exposure times to A beta. Of interest, we discuss the distinct contributions of the amide modes from A beta that are enhanced by the TERS process and in particular the suppression of the amide I mode in the context of recently reported observations in the literature.

Struvite crystallization has been so far proved to be a potential technology for nitrogen and phosphorus recovery from nutrient-rich wastewater. However, humic acid (HA) among organic matters in nutrient-rich wastewaters would inevitably exert an adverse impact on the crystallization. Therefore, in the present study, we innovatively propose a process monitor chart to accurately differentiate and quantify the nucleation and crystal growth of struvite crystallization by means of constant composition technique, thereby probing the effect of HA on the nucleation and growth kinetics of struvite. Moreover, the mechanism underlying the interaction between HA and struvite crystals was also explored by FTIR and XPS analysis. The results indicated that HA not only significantly prolonged the induction time, but also decreased the growth rate of struvite crystals. This can be explained by the fact that HA is prone to complex with the reactant, and its subsequent adsorption on the surface of struvite crystals performs during the crystallization process. Consequently, the crystal morphology initially varied from rod-like shape to trapezoidal prism, and ultimately to triangular prism, as HA concentration gradually increased from 0 to 100 mg/L. Interestingly, the interaction between HA and struvite crystals is likely to be triggered by the formation of amide, HA-Mg2+ complex and phosphate ester on the crystal surface. These findings herein put forward an innovate method to elucidate the inhibitory effect of organic matter on the nucleation and growth kinetics of struvite, which can provide a theoretical basis for understanding the interference of organic pollutants with struvite crystallization.

The implementation of direct and mild catalytic synthesis of products from benign materials using inexpensive catalysts is a major goal of chemists. Herein, a mild O-2-interrupted hydrogen borrowing strategy using easily accessible and high efficient cobalt complex was reported for direct synthesis of alpha, beta-unsaturated esters from unactivated esters and alcohols. This new route had good tolerance on broad substrate scope (alcohols, acetates, propionates and dios) and functional group with the highest yield of 89.1%. Systematic mechanism investigation revealed the cobalt complex was activated by t-BuOK via double deprotonation of PN5P ligand and removal of dichloro ligands, followed by two-fold alcohols activation and dehydrogenation. Also, the oxygen atmosphere was demonstrated very crucial for such interrupted hydrogen borrowing pathway. (C) 2018 Elsevier Inc. All rights reserved.

Novel derivatives of quinolizidine alkaloid (-)-cytisine were synthesised. ADME properties, cytotoxicity against HEK293 cells and activity against viruses of influenza A/California/07/09(H1N1)pdm09 virus (IAV) and human parainfluenza virus type 3 (HPIV3) were evaluated. It was shown, that 9-carboxamides of methylcytisine (with phenyl and allyl urea’s fragments) are most active compounds against IAV probably due to predicted in silico peculiarity of their interactions with the 4R7B active site of IAV neuraminidase. Indexes of selectivity (SI) calculated as ratio of CC50/IC50 of these ureas are 47 and 59 correspondingly. It was also found, that derivatives obtained from allyl isocyanate and (-)-cytisine or 9,11-dibromocytisine are able to inhibit a reproduction of HPIV3 with SI = 58 and 95. Moreover, last compound – (1 R,5R)-N-allyl-9,11-dibromo-8-oxo-1,5,6,8-tetrahydro-2H-1,5-methanopyrido[1,2-a][1,5]diazocine-3(4H)-carboxamide with two bromine atom in 2-pyridone core of starting (-)-cytisine molecule, demonstrated high activity against HPIV3 (SI = 95) and moderate activity against IAV (SI = 16).

Scaffolds of 2-acylamino-1,3,4-oxadiazole have been recently developed as transglycosylase inhibitors against MRSA. In the present study, structure-activity relationships of new derivatives of 2-acylamino-1,3,4-oxadiazole were explored with focus on the substitution of the aromatic rings. The in vitro antibacterial activity of these compounds against MRSA strain was evaluated using agar disc diffusion method. These inhibitors have an amide linker between 1,3,4-oxadiazole ring and the aromatic ring B. The role of this linker on the bioactivity of the compounds was also studied. The results showed promising series of 2–aminophosphonate-1,3,4-oxadiazole as inhibitors for MRSA strain. Both series revealed two structural features which appear to be essential for anti-MRSA activities, the first one is the incorporation of two electron-withdrawing groups at meta- and para- positions within aromatic ring B which contributed to a higher activity against MRSA strain. The second is the new -aminophosphonate linker serving as bio-isosteric analogue of the corresponding amide linker and giving comparable results with the amide derivatives. [GRAPHICS]

Differentiation of bacterial spores via 2D-IR spectroscopy

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.

Gut Bacteria of Water Monitor Lizard (Varanus salvator) Are a Potential Source of Antibacterial Compound(s)

For the past few decades, there has been limited progress in the development of novel antibacterials. Previously, we postulated that the gut microbiota of animals residing in polluted environments are a forthcoming supply of antibacterials. Among various species, the water monitor lizard is an interesting species that feeds on organic waste and the carcass of wild animals. Gut microbiota of the water monitor lizard were sequestered, identified and cultivated in RPMI-1640 to produce conditioned medium (CM). Next, the antimicrobial properties of CM were evaluated versus a selection of Gram-negative (Escherichia coli K1, Serratia marcescens, Pseudomonas aeruginosa, Salmonella enterica and Klebsiella pneumoniae) and Gram-positive bacteria (Streptococcus pyogenes, methicillin-resistant Staphylococcus aureus, and Bacillus cereus). CM were partially characterized by heat inactivation at 95 degrees C for 10 min and tested against P. aeruginosa and S. pyogenes. CM were also tested against immortalized human keratinocytes (HaCaT) cells lines. The results demonstrated that gut microbiota isolated from water monitor lizard produced molecules with remarkable bactericidal activities. To determine the identity of the active molecules, CM were subjected to Liquid Chromatography-Mass Spectrometry. Several molecules were identified belonging to the classes of flavonoids, terpenoids, alkaloids, polyhydroxy alkaloids, polyacetylenes, bisphenols, amides, oxylipin and pyrazine derivatives with known broad-spectrum antimicrobial, anti-tumour, anti-oxidant, anti-inflammatory, and analgesic attributes. Furthermore, the detailed analysis of these molecules could lead us to develop effective therapeutic antibacterials.
