The usage of flavored electronic nicotine delivery systems (ENDS) is popular, specifically in the teen and young adult age-groups. The possible cardiac toxicity of the flavoring aspect of ENDS is largely unknown. Vaping, a form of electronic nicotine delivery, uses e-liquid to generate e-vapor, an aerosolized mixture of nicotine and/or flavors. We report our investigation into the cardiotoxic effects of flavored e-liquids. E-vapors containing flavoring aldehydes such as vanillin and cinnamaldehyde, as indicated by mass spectrometry, were more toxic in HL-1 cardiomyocytes than fruit-flavored e-vapor. Exposure of human induced pluripotent stem cell-derived cardiomyocytes to cinnamaldehyde or vanillin-flavored e-vapor affected the beating frequency and prolonged the field potential duration of these cells more than fruit-flavored e-vapor. In addition, vanillin aldehyde-flavored evapor reduced the human ether-a-go-go-related gene (hERG)-encoded potassium current in transfected human embryonic kidney cells. In mice, inhalation exposure to vanillin aldehyde-flavored e-vapor for 10 wk caused increased sympathetic predominance in heart rate variability measurements. In vivo inducible ventricular tachycardia was significantly longer, and in optical mapping, the magnitude of ventricular action potential duration alternans was significantly larger in the vanillin aldehyde-flavored e-vaporexposed mice than in controls. We conclude that the widely popular flavored ENDS are not harm free, and they have a potential for cardiac harm. More studies are needed to further assess their cardiac safety profile and long-term health effects. NEW & NOTEWORTHY The use of electronic nicotine delivery systems (ENDS) is not harm free. It is not known whether ENDS negatively affect cardiac electrophysiological function. Our study in cell lines and in mice shows that ENDS can compromise cardiac electrophysiology, leading to action potential instability and inducible ventricular arrhythmias. Further investigations are necessary to assess the long-term cardiac safety profile of ENDS products in humans and to better understand how individual components of ENDS affect cardiac toxicity.

The CAS is 123-11-5. Through research, I have a further understanding and discovery of 4-Methoxybenzaldehyde

This paper reports the synthesis and characterization of Cu nanoparticle loaded, surfactant free metallovesicles (CuNPs@vesicles) as nanoreactors to produce benzimidazoles via cascade reaction. The vesicles exhibited uniform size distribution, spherical morphology, excellent stability and efficient Cu loading. This strategy is unique for the fact that, environmental contaminants like nitroaniline have been utilized as precursor and converted into fine chemicals of commercial significance via non-toxic intermediates. CuNPs@vesicles reduces 2-nitroaniline to o-phenylenediamine which further acts as precursor for benzimidazole synthesis. Thus the reaction occurs via two step cascade pathway comprising reduction and C-N cross coupling reactions in water. The preliminary studies suggest encouraging results for performing dehydrogenative coupling under relatively mild conditions using CuNPs@vesicles as a catalyst. All the products are obtained in good to excellent yield with facile catalyst regeneration and recyclability upto 5 cascading cycles. (C) 2021 Elsevier B.V. All rights reserved.

Seventeen chalcone analogues were synthesized from 7-methoxy-3,4-dihydronaphthalen1(2H)-one and various aromatic aldehydes under basic conditions and their therapeutic properties were studied in mouse hippocampal cell line HT-22 against neuronal cell death induced by glutamate. From this study, we selected an analogue C01 as a active compound which showed significantly high neuroprotection. This compound inhibited Ca2+ influx and reactive oxygen species (ROS) accumulation inside cells. The glutamate-induced cell death was analyzed by flow cytometry and it showed that C01 significantly reduced apoptotic or dead cell induced by 5 mM glutamate. Western blot analysis indicates that glutamate-mediated activation of MAPKs were inhibited by compound C01 treatment. In addition, the C01enhanced Bcl-2 and decreased Bax, the anti and pro apoptotic proteins respectively. Further analysis showed that, C01 prevented the nuclear translocation of AIF (apoptosis inducing factor) and inhibited neuronal cell death. Taken together, compound C01 treatment resulted in decreased neurotoxicity induced by 5 mM of glutamate. Our finding confirmed that compound C01 has neuro-therapeutic potential against glutamate-mediated neurotoxicity.

Herein, we report highly chemoselective hydrogenation of alpha,beta-unsaturated carbonyls to saturated carbonyls catalyzed by cobalt nanoparticles supported on the biomass-derived carbon from bamboo shoots with molecular hydrogen in water, which is the first prototype using a heterogeneous non-noble metal catalyst for such organic transformation as far as we know. The optimal cobalt nanocatalyst, CoOx@NC-800, manifested remarkable activity and selectivity for hydrogenation of C=C in alpha,beta-unsaturated carbonyls under mild conditions. A broad set of alpha,beta-aromatic and aliphatic unsaturated carbonyls were selectively reduced to their corresponding saturated carbonyls in up to 99 % yields with good tolerance of various functional groups. Meanwhile, a new straightforward one-pot cascade synthesis of saturated carbonyls was realized with high activity and selectivity via the cross-aldol condensation of ketones with aldehydes followed by selective hydrogenation. More importantly, this one-pot strategy is applicable for the expedient synthesis of Loureirin A, a versatile bioactive and medicinal molecule, from readily available starting materials, further highlighting the practical utility of the catalyst. In addition, the catalyst can be easily separated for successive reuses without significant loss in both activity and selectivity.

A one-step, three-component Petasis reaction of isatin derived 5-arylboronate-3-substituted oxindole derivatives with salicylaldehydes and secondary amines affords new enantiomerically pure structurally diverse 5-alpha-(3-substituted-oxindole)-benzylamine derivatives. The reaction shows good substrate and reagent scope affording the products with good to excellent yields (up to >99 % yield) and enantioselectivities (up to 99 % ee) using cheap and readily available (R)-BINOL as the organocatalyst. A diastereoselective version of the reaction was also developed where moderate yields (37 to 55 % yield), excellent enantioselectivities (up to 99 % ee) and good diastereoselectivities (up to 86 % de) were obtained for new 5-alpha-(3-hydroxy-oxindole)-benzylamine derivatives, having two stereocenters. The reaction is also feasible on gram-scale.

An atom economic procedure for the regioselective synthesis of bridged seven-membered-ring compounds from simple reactants such as ynones and indene-1,3-dione has been developed. This process was realized through the one-pot reactions of ring-expansion of indene-1,3-dione with alkynyl ketones and successive formal [4+2] cycloaddition. The Michael addition reaction is the key for the regioselectivity of the formal [4+2] cycloaddition.
