Formaldehyde and VOC emissions from plywood panels bonded with bio-oil phenolic resins

Pyrolysis bio-oil was used to partially substitute for phenol in reacting with formaldehyde for the production of bio-oil phenol formaldehyde plywood (BPFP) panels, with the phenol substitution ratio being 20%, 40%, or 60%. Emissions of formaldehyde and volatile organic compounds (VOCs) from the BPFP panels were studied using solid-phase micro-extraction (SPME) followed by headspace gas chromatography/mass spectrometry (GC/MS), and were compared to those from the phenol formaldehyde plywood (PFP) panels. The sources for VOCs were analyzed, and the health risks associated with the BPFP were examined. Results showed that at 80 degrees C: (1) Formaldehyde emissions from the BPFP panels were increased to about 4 times that of PFP; (2) VOCs emissions were significantly reduced by up to 84.9% mainly due to the greatly reduced phenol emissions, although the total number of VOCs was increased from 20 to 35; (3) BPFP presents greatly increased carcinogenic and non-carcinogenic health risks because of its much stronger emissions of formaldehyde, N,N-dimethylformamide, benzofuran, furfural, and many chemicals from the bio-oil. It is highly advisable that the health risks are properly taken care of before the wide application of BPFP, or similar bio-oil based engineered wood products. (C) 2020 Elsevier Ltd.

Beyond ecstasy: Alternative entactogens to 3,4-methylenedioxymethamphetamine with potential applications in psychotherapy

The last two decades have seen a revival of interest in the entactogen 3,4-methylenedioxy-N-methylamphetamine (MDMA) as an adjunct to psychotherapy, particularly for the treatment of post-traumatic stress disorder. While clinical results are highly promising, and MDMA is expected to be approved as a treatment in the near future, it is currently the only compound in its class of action that is being actively investigated as a medicine. This lack of alternatives to MDMA may prove detrimental to patients who do not respond well to the particular mechanism of action of MDMA or whose treatment calls for a modification of MDMA’s effects. For instance, patients with existing cardiovascular conditions or with a prolonged history of stimulant drug use may not fit into the current model of MDMA-assisted psychotherapy, and could benefit from alternative drugs. This review examines the existing literature on a host of entactogenic drugs, which may prove to be useful alternatives in the future, paying particularly close attention to any neurotoxic risks, neuropharmacological mechanism of action and entactogenic commonalities with MDMA. The substances examined derive from the 1,3-benzodioxole, cathinone, benzofuran, aminoindane, indole and amphetamine classes. Several compounds from these classes are identified as potential alternatives to MDMA.

Electrochemical study of dibenzo-xanthene and dihydrobenzochromono pyrazole derivatives

The electrochemical reduction of 9 substituted aryl-5H-dibenzo[b,i]xanthene-5,7,12,14(13H)-tetraones (DBXT) and 10 substituted 3-methyl-1,4-diphenyl-1,4-dihydrobenzo [6,7]chromeno[2,3-c]pyrazole-5,10 diones (DCPD) in water/DMF mixture (30/70 v/v) has been studied by cyclic voltammetry, choronoamperometry and differential pulse voltammetry at a glassy carbon electrode. Our data show that the electrochemical reduction of DBXTs takes place in two consecutive two-electron processes, ErEq, corresponding to two successive reductions of naphthoquinone moieties to 1,4-naphthalenediol groups (13-phenyl-13H-dibenzo[b,i]xanthene-5,7,12,14-tetraol). On the other hand, electrochemical reduction of DCPDs shows a reversible two-electron process corresponding to the reduction of naphthoquinone moiety to 1,4-naphthalenediol group. Our data also show that DBXT derivatives containing electron-withdrawing groups participate in the comproportionation reaction, while the fully reduced DBXT derivatives with electron-donating groups are unstable and readily undergoes side reactions. The calculated diffusion coefficient of some DBXT (5 x 10(-7) cm(2)/s) and DCPD (2 x 10(-7) cm(2)/s) derivatives shows that there is no significant relationship between the diffusion coefficients and substituent groups. The smaller diffusion coefficient of DCPD than that of the DBXT derivatives can be related to the formation of more and stronger hydrogen bonds by DCPD than DBXT derivatives. In this work, also, the correlation of E-1/2 with sigma constants and the adsorption behavior of DBXTs and DCPDs has been investigated. (C) 2019 Elsevier Ltd. All rights reserved.

Copper Catalyzed Oxidative Arylation of Tertiary Carbon Centers

We describe herein a Cu(OTf)(2) catalyzed oxidative arylation of a tertiary carbon-containing substrate including aryl malononitriles, 3-aryl benzofuran-2-ones, and 3-aryl oxindoles. In some cases, the nitrile groups of the aryl malononitriles undergo further reactions leading to lactones or imines. These reaction conditions are applicable for a range of arenes, including phenols, anilines, anisoles, and heteroarenes. Mechanistic studies support the formation of a cationic intermediate via a two-electron oxidation.

Singlet oxygenation of triquinacene, barrelene, and homobarrelene

The singlet oxygenation of three polycyclic hydrocarbons, triquinacene, barrelene and homobarrelene was studied. Triquinacene reacted by way of a perepoxide intermediate, transferring an oxygen atom to another triquinacene molecule to give exclusively the mono epoxide. Barrelene, on the other hand, underwent a rare homo-Diels-Alder reaction with O-1(2) to give the decomposition product from the initial tetracyclic 1,2-dioxolane leading to benzofuran. The latter reacted with O-1(2) in a [2 + 2] cycloaddition to give an unstable 1,2-dioxetane which collapsed to 2-formylphenyl formate. The latter was independently synthesized via singlet oxygenation of authentic benzofuran. Homobarrelene reacted in a similar fashion to give a homo-Diels product, decomposition of which led to a keto aldehyde which was characterized spectroscopically. Computational work confirms the barrelene and homobarrelene reactions with O-1(2) as concerted [pi(2)(s)+ pi 2(s)+ pi 2(s)] cycloadditions. (C) 2020 Elsevier Ltd. All rights reserved.

Spiroindolone analogues bearing benzofuran moiety as a selective cyclooxygenase COX-1 with TNF-alpha and IL-6 inhibitors

To design and discover a new compound can used as a COX with TNF-alpha and IL-6 inhibitors is highly challenge. A series of spiroindolone-bearing benzofuran moieties were resynthesized from the chalcone-based benzo[b]furan with substituted isatin, and amino acids. The requisite spiroindolone analogues were tested for their potential inhibitory activities against lipid metabolizing enzymes such as cyclooxygenase COX-1, COX-2, and the release of pro-inflammatory cytokines interleukin IL-6, and tumor necrosis factor TNF-a. Among the tested compounds, 5a, 5c, 5h, 5i, 5l, and 5p exhibited COX-1 inhibitor selectively with percent of inhibition 40.81-83.4% and IC50 values ranging from 20.42 mu M to 38.24 mM. In addition, all the synthesized target compounds possessed lipopolysaccharide-induced TNF-alpha, and IL-6 expression with a varying degree of COX-1 inhibition. Compounds 5d, 5e, 5f, 5g, and 5k markedly inhibited TNF-alpha, and IL-6 release in WI-38 fibroblast cells. Molecular docking of the most effective and highly selective compounds were investigated and shown important binding mechanisms which could affect pro-inflammatory enzymes and cytokines via the inhibition of COX-1, COX-2, IL-6, and TNF-alpha.

High-Energy Proton-Beam-Induced Polymerization/Oxygenation of Hydroxynaphthalenes on Meteorites and Nitrogen Transfer from Urea: Modeling Insoluble Organic Matter?

Formation and structural modification of oxygenated polycyclic aromatic hydrocarbons (oxyPAHs) by UV irradiation on minerals have recently been proposed as a possible channel of PAH transformation in astrochemical and prebiotic scenarios of possible relevance for the origin of life. Herein, it is demonstrated that high-energy proton-beam irradiation in the presence of various meteorites, including stony iron, achondrite, and chondrite types, promotes the conversion of two representative oxyPAH compounds, 1-naphthol and 1,8-dihydroxynaphthalene, to complex mixtures of oxygenated and oligomeric derivatives. The main identified products include polyhydroxy derivatives, isomeric dimers encompassing benzofuran and benzopyran scaffolds, and, notably, a range of quinones and perylene derivatives. Addition of urea, a prebiotically relevant chemical precursor, expanded the range of identified species to include, among others, quinone diimines. Proton-beam irradiation of oxyPAH modulated by nitrogen-containing compounds such as urea is proposed as a possible contributory mechanism for the formation and processing of insoluble organic matter in meteorites and in prebiotic processes.

Synthesis and biological evaluation of a new series of benzofuran-1,3,4-oxadiazole containing 1,2,3-triazole-acetamides as potential alpha-glucosidase inhibitors

A series of new benzofuran-1,3,4-oxadiazole containing 1,2,3-triazole-acetamides 12a-n as potential anti-alpha-glucosidase agents were designed and synthesized. alpha-Glucosidase inhibition assay demonstrated that all the synthesized compounds 12a-n (half-maximal inhibitory concentration [IC50] values in the range of 40.7 +/- 0.3-173.6 +/- 1.9 mu M) were more potent than standard inhibitor acarbose (IC50 = 750.0 +/- 12.5 mu M). Among them, the most potent compound was compound 12c, with inhibitory activity around 19-fold higher than acarbose. Since the most potent compound inhibited alpha-glucosidase in a competitive mode, a docking study of this compound was also performed into the active site of alpha-glucosidase. In vitro and in silico toxicity assays of the title compounds were also performed.
