(+)-Nootkatone, a non-food bioactive natural bicyclic sesquiterpene ketone, is isolated from Chamaecyparis nootkatensis [D. Don] Spach as a renewable forest resource. In continuation of our effort to develop synthetic natural derived insecticides from non-food bioactive products, a small library of thirty N-(1,3- thiazol-2-yl) carboxamides fused (+)-nootkatone was prepared by molecular hybridization and characterized by H-1/C-13 NMR, HR-MS, and IR spectroscopy. Their insecticidal activities against Mythimna separata Walker and Plutella xylostella Linnaeus were evaluated. Compounds B6, B7, B9, B19-21 and B24 showed better insecticidal activity against M. separata than the botanical insecticide azadirachtin, and their LC50 values ranged from 0.55 -0.68 mg/mL. Particularly, compound B9 exhibited 1.87-fold more pronounced insecticidal activity against M. separata than azadirachtin. The insecticidal activity of B21 against P. xylostella was 1.37-fold of that of azadirachtin. Through acetylcholinesterase (AChE) inhibitory activity and molecular docking studies, AChE may be the insecticidal target of B9 against M. separata. In addition, three pronounced compounds B9, B21 and B24 exhibited low hemolytic and cytotoxic activities on normal mammalian cells. These findings will give insights into the further development of (+)-nootkatone derivatives as potentially synthetic natural derived insecticides for pest management.

An unusual phenomenon occurred in new display cases at the Rijksmuseum four months after their installation in April 2013. White deposits were visible on glass windows, silicone door gaskets, black structural adhesive seals, and on works of art. The works of art most affected by these deposits were bronze sculptures, wooden and waxed objects, tempera, and oil paintings. In this study the deposits were chemically characterised using (pyrolysis-)gas chromatography-mass spectrometry ((Py-)GC-MS), mu-Raman spectroscopy (mu-Raman), ion chromatography (IC), and scanning electron microscopy combined with energy dispersive X-ray spectroscopy (SEM-EDX). Five chemically different crystalline deposits were found. They were identified as organic salts of the base 2,2,6,6-tetramethyl-4-piperidinol (TMP-ol), a secondary amine, and five different carboxylic acids. It was found that TMP-ol, which is part of the UV-light stabiliser Tinuvin-770, emitted from the structural adhesive Terostat-9220. Terostat-9220 was used in large quantities in the display cases to adhere glass windows to metal parts. The carboxylic acids derived from both construction materials used to build the cases and from conservation materials present on the exhibited works of art. The carboxylic acids involved were 2,4-dichlorobenzoic acid, formic acid, methacrylic acid, palmitic acid, and an unknown carboxylic acid, respectively emitted from peroxide-cured silicone gaskets, panels of medium-density fibreboard (MDF), UV-adhesive, beeswax containing products, and from an unknown acidic conservation product or binding medium. The identification of the crystalline deposits was supported by their syntheses in the laboratory. Since 2013, similar deposits have been observed in a number of museum collections worldwide. A treatment for preventing further growth of the deposits was developed and applied in the Rijksmuseum showcases.

I found the field of Environmental Sciences & Ecology very interesting. Saw the article Exploring QSAR models for assessment of acute fish toxicity of environmental transformation products of pesticides (ETPPs) published in 2020.0. HPLC of Formula: C7H4Cl2O2, Reprint Addresses Roy, K (corresponding author), Jadavpur Univ, Dept Pharmaceut Technol, Drug Theoret & Cheminformat Lab, Kolkata 700032, India.. The CAS is 50-30-6. Through research, I have a further understanding and discovery of 2,6-Dichlorobenzoic acid

Environmental transformation products of pesticides (ETPPs) have a great deal of ecological impact owing to their ability to cause toxicity to the aquatic organisms, which can then be translated to the humans. The limited experimental data on biochemical and toxic effects of ETPPs, the high test costs together with regulatory limitations and the international push to reduce animal testing encourage greater dependence on predictive in silico techniques like quantitative structure-activity relationship (QSAR) models. The aim of the present work was to explore the key structural features, which regulate the toxicity towards fishes, for 85 ETPPs using a partial least squares (PLS) regression based chemometric model developed according to Organisation for Economic Co-operation and Development (OECD) guidelines. The model was extensively validated using both internal and external validation metrics, and the results so obtained justify the reliability and usefulness of the developed model (Q(2) = 0.648, R-pred(2) or Q(F1)(2) = 0.734 and Q(F2)(2) = 0.733). From the developed model, we can conclude that lipophilicity, polarity, presence of branching and the functional form of 0-atom in the transformed structures of pesticides are the important features that are to be considered during ecotoxicity assessment of ETPPs. The information obtained from the descriptors of the developed model could be utilized in the future for assessing ETPPs with the benefit of providing an early warning of their potentially detrimental effect on fishes for regulatory purposes.

Subunit-selective proteasome inhibitors are valuable tools to assess the biological and medicinal relevance of individual proteasome active sites. Whereas the inhibitors for the beta 1c, beta 1i, beta 5c, and beta 5i subunits exploit the differences in the substrate-binding channels identified by X-ray crystallography, compounds selectively targeting beta 2c or beta 2i could not yet be rationally designed because of the high structural similarity of these two subunits. Here, we report the development, chemical synthesis, and biological screening of a compound library that led to the identification of the beta 2c- and beta 2i-selective-compounds LU-002c (4; IC50 beta 2c: 8 nM, IC50 beta 2i/beta 2c: 40-fold) and LU-002i (5; IC50 beta 2i: 220 nM, IC50 beta 2c/beta 2i: 45-fold), respectively. Co-crystal structures with beta 2 humanized yeast proteasomes visualize protein-ligand interactions crucial for subunit specificity. Altogether, organic syntheses, activity-based protein profiling, yeast mutagenesis, and structural biology allowed us to decipher significant differences of beta 2 substrate-binding channels and to complete the set of subunit-selective proteasome inhibitors.

A new synthetic method toward direct C-N bond formation through saturated C-H amination of benzylic hydrocarbons and inactive aliphatic alkanes with primary aromatic amines under an inexpensive catalyst/oxidant (Cu/DTBP) system has been developed. Both aminopyridines and anilines could react smoothly with primary and secondary benzylic C-H substrates or cyclohexane to form the corresponding aromatic secondary amines in moderate to good yields. This protocol has the advantages of wide functional group tolerance and use of readily available raw materials.

An operationally simple nickel-catalyzed hydroarylation reaction for alkynes is described. This three component coupling reaction utilizes commercially available alkynes and aryl bromides, along with water and Zn. An air-stable and easily synthesized Ni(II) precatalyst is the only entity used in the reaction that is not commercially available. This reductive cross-coupling reaction displays a fairly unusual anti selectivity when aryl bromides with ortho substituents are used. In addition to optimization data and a preliminary substrate scope, complementary experiments including deuterium labeling studies are used to provide a tentative catalytic mechanism. We believe this report should inspire and inform other Ni-catalyzed carbofunctionalization reactions.

Providing new methods for the selective functionalization of small molecules is highly desirable, because installing molecular diversity in a desired position, for example, allows one to modulate bioactive molecules. This work reports a method for the selective functionalization of anilines using hexafluoroisopropanol (HFIP) as a solvent to promote an acid-catalyzed hydroarylation of olefins. Mechanistic experiments revealed that HFIP both protonates the alkene and selectively enables anilines toward the electrophilic aromatic substitution. This powerful strategy has been applied to the functionalization of the anti-inflammatory mefenamic acid with chemocontrol and regiocontrol.

Herein we disclosed the utilization of copper loaded zinc oxide (ZnO-Cu) for its stimuli (O-2/light) responsive switchable performance between its reduced (S-1) and oxidized (S-2) state for two antagonistic reactions, namely oxidation of alkyl arenes/heteroarenes to aldehydes/ketones and reduction of nitro arenes/heteroarenes corresponding amines. The two states of the catalyst showed its switchable performance as highly active and poorly active catalyst for oxidation and reduction, and both reactions could be turned off and on by changing the stimuli (light and O-2/N-2). The switching efficiency between the states and their relative reactivity were found to be consistent under variety of reaction conditions and remain unaltered irrespective of oxidation-reduction (or vice versa) sequence and substrates used in the reaction. The photo catalysts (S-1 and S-2) demonstrated good catalytic activity, multiple reusability, broad substrate scope, and reasonable functional group tolerance for both the reactions and probed its quality performance in a large-scale setup. The system was used in an assisted tandem catalysis setup for the synthesis of benzyl amines utilizing both oxidation and reduction reaction by stimuli responsive switching between the states of the catalyst.

An efficient and operationally simple protocol has been demonstrated for the synthesis of 1,3,5,7-tetrasubstituted pyrimido[4,5-d]pyrimidines via TBHP-mediated direct oxidative coupling of N-uracil amidines and methylarenes under metal-free conditions. Due to the inherent stability of methylarenes compared to aldehydes, the presented synthetic protocol is adaptable to a broad substrate scope, is operationally simple, has no need for stringent protection in the whole preparation process, and has the potential to prepare valuable products that are currently inaccessible or challenging to prepare using conventional methods. It is a significantly important complement to the conventional synthetic methods. The reaction possesses an efficient tandem oxidation-imination-cyclization process.
