Starting from diverse alkene-tethered aryl iodides and O-benzoyl-hydroxylamines, the enantioselective reductive cross-electrophilic 1,2-carboamination of unactivated alkenes was achieved using a chiral pyrox/nickel complex as the catalyst. This mild, modular, and practical protocol provides rapid access to a variety of beta-chiral amines with an enantioenriched aryl-substituted quaternary carbon center in good yields and with excellent enantioselectivities. This process reveals a complementary regioselectivity when compared to Pd and Cu catalysis.

Severe acute respiratory syndrome coronavirus (SARS-CoV-2) disease is a global rapidly spreading virus showing very high rates of complications and mortality. Till now, there is no effective specific treatment for the disease. Aloe is a rich source of isolated phytoconstituents that have an enormous range of biological activities. Since there are no available experimental techniques to examine these compounds for antiviral activity against SARS-CoV-2, we employed an in silico approach involving molecular docking, dynamics simulation, and binding free energy calculation using SARS-CoV-2 essential proteins as main protease and spike protein to identify lead compounds from Aloe that may help in novel drug discovery. Results retrieved from docking and molecular dynamics simulation suggested a number of promising inhibitors from Aloe. Root mean square deviation (RMSD) and root mean square fluctuation (RMSF) calculations indicated that compounds 132, 134, and 159 were the best scoring compounds against main protease, while compounds 115, 120, and 131 were the best scoring ones against spike glycoprotein. Compounds 120 and 131 were able to achieve significant stability and binding free energies during molecular dynamics simulation. In addition, the highest scoring compounds were investigated for their pharmacokinetic properties and drug-likeness. The Aloe compounds are promising active phytoconstituents for drug development for SARS-CoV-2.

4-Hydroxy-3-methyl-2(1H)-quinolone (1), a molecule known for a long time and recently discovered from a Brassicaceae plant Isatis tinctoria without providing sufficient evidence to support the structure, was isolated from a fermentation extract of Burkholderia sp. 3Y-MMP isolated from a soil by a Zn2+ enrichment culture. Detailed spectroscopic analyses by MS and NMR, combined with C-13 chemical shift comparison with literature values of the related compounds and a synthetic preparation of 1, allowed its first full NMR characterization and identification of 2-quinolone but not 2-quinolinol (2) as the preferred tautomer for this heterocyclic system. While the metal-chelating activity was negligible, compound 1 at 10 mu M, a concentration lower than that in liquid production cultures, quenched hydroxy radical-induced chemiluminescence emitted by luminol by 86%. Because some Burkholderia species are pathogenic to plants and animals, the above result suggests that 1 is a potential antioxidant to counteract reactive oxygen species-based immune response in the host organisms.

We characterized the flavor chemicals in a broad sample of commercially available electronic cigarette (EC) refill fluids that were purchased in four different countries. Flavor chemicals in 277 refill fluids were identified and quantified by gas chromatography-mass spectrometry, and two commonly used flavor chemicals were tested for cytotoxicity with the MTT assay using human lung fibroblasts and epithelial cells. About 85% of the refill fluids had total flavor concentrations >1mg/ml, and 37% were >10mg/ml (1% by weight). Of the 155 flavor chemicals identified in the 277 refill fluids, 50 were present at >= 1mg/ml in at least one sample and 11 were >10mg/ml in 54 of the refill fluids. Sixty-one% (170 out of 277) of the samples contained nicotine, and of these, 56% had a total flavor chemical/nicotine ratio >2. Four chemicals were present in 50% (menthol, triacetin, and cinnamaldehyde) to 80% (ethyl maltol) of the samples. Some products had concentrations of menthol (Menthol Arctic) and ethyl maltol (No. 64) that were 30 times (menthol) and 100 times (ethyl maltol) their cytotoxic concentration. One refill fluid contained cinnamaldehyde at similar to 34% (343 mg/ml), more than 100,000 times its cytotoxic level. High concentrations of some flavor chemicals in EC refill fluids are potentially harmful to users, and continued absence of any regulations regarding flavor chemicals in EC fluids will likely be detrimental to human health.

A 2,2 ‘-Bipyridine-based ionic compound named 2,2 ‘-bipyridinium dihydrogen phosphate was synthesized by addition of phosphoric acid to a solution of 2,2 ‘-Bipyridine in dichloromethane. After the characterization using FT-IR, mass, H-1, C-13 and P-31 NMR techniques, it was used as a Bronsted dicationic acidic catalyst for the promotion of the synthesis of 2-arylidene malononitrile and 5-arylidene barbituric acid derivatives via Knoevenagel condensation reaction in water. Some of the advantages of this method are the utilization of an easy preparable, cost-effective and eco-friendly organic salt as a catalyst within high rates and yields of the reactions, simple and quick work-up and acceptable reusability of the catalyst.

A highly versatile and efficient ultrasound promoted synthesis of xanthenedione derivatives is achieved through condensation of dimedone with various aromatic aldehydes using boric acid as catalyst in ethanol-water medium. The advantages of this method being, mild reaction conditions, short reaction time, easy work-up, purification of products by non-chromatographic methods and additionally this method provides excellent yields. Two of the Xanthendiones derivatives 3a and 3b gave good crystals on recrystallization and their molecular structures were confirmed by crystallographic studies. The molecules in the crystal lattice are held together by weak intermolecular C-H center dot center dot center dot O and C-H center dot center dot center dot N interactions. Further insights into these interactions using Hirshfeld surface analysis and DFT/B3LYP studies show that in compound 3a H center dot center dot center dot H (54.7%), O center dot center dot center dot H (18.3%) and in 3b H center dot center dot center dot H (53.7%), O center dot center dot center dot H (17.6%) are the major contributors to the intermolecular interactions which stabilize the crystal structures. In order to determine molecular electrical transport properties, we studied the energy difference between Highest Occupied, HOMO, and Lowest Unoccupied, LUMO orbitals and the HOMO and LUMO energy gap for compounds 3a and 3b was found to be 3.9261 eV and 4.6436 eV respectively. The 2D fingerprint plot provided percentage contribution of each individual atom-to-atom interactions. The Mulliken atomic charges and molecular electrostatic potential on molecular van der Waals surface were calculated to know the electrophilic and nucleophilic regions of the molecular surface.

Escherichia coli (E. coli) is recognized as an indicator of fecal bacterial contamination, and the induction of intracellular beta-galactosidase (Gal) is commonly used for sensitive and selective E. coli detection. However, this method requires a permeabilization process to ensure that the Gal substrate and product are highly permeable through the E. coli membrane, making it unsuitable for simple point-of-care detection. Here, we report a sensitive electrochemical method for E. coli detection that does not require a permeabilization process. Intracellular Gal expression is increased via induction by isopropyl-beta-D-thiogalactopyranoside (IPTG). 4-Methoxyphenyl-beta-D-galactopyranoside (MPGP) and 4-methoxyphenol (MP) are used as the highly cell-permeable Gal substrate and product, respectively. Externally-added tyrosinase (Tyr) converts MP into electrochemically active 4-methoxycatechol, which is then electrochemically oxidized via electrochemical-chemical redox cycling involving an electrode, 4-methoxycatechol, and tris(2-carboxyethyl)phosphine. The presence of MPGP during the induction of intracellular Gal led to amplified MP production. The results of four different detection methods using three Gal substrates (MPGP, phenyl-beta-D-galactopyranoside, and 4-aminophenyl-beta-D-galactopyranoside) were compared. The detection limit for both drinking water and tap water spiked with E. coli, obtained following a 2-h-long IPTG treatment and 5-min-long Tyr reaction, was similar to 2 x 10(3) colony-forming units (CFU)/mL, indicating that this method can be applied to monitoring E. coli contamination in water samples. Importantly, the present method does not require the electrode modification, affinity binding, washing, and filtration steps.
