For the synthesis of coumarin derivatives using the Pechmann condensation scheme, an acidic ionic liquid catalyst, abbreviated as [EBsImH][HSO4], was prepared from the ring opening of 1,4-butanesultone by 1-ethylimidazole, followed by the addition of 1 equiv. H2SO4(c). The [EBsImH][HSO4]-catalyzed Pechmann condensation reactions proceeded smoothly in a batch setup, with recyclable [EBsImH][HSO4] showing great catalytic activity. The acidic ionic liquid catalyst [EBsImH][HSO4] was recovered from EtOAc/H2O extraction of the product mixture, where the H2O layer was worked up and dried for reuse in consecutive runs of the Pechmann condensation reactions, maintaining >85% conversion for four times. The catalytic reactions were also carried out in a microfluidic flow setup. The flow parameters, the reactant molar amounts, and the additional H2SO4 as a modifying acid catalyst were optimized in the current case study. A minimum conversion rate of 2.8 g/hr of coumarin derivatives was demonstrated.

Cyclometalated (ppy)Pt-II complexes (ppy = 2-phenylpyridinato-C-2,N) catalyze the intramolecular cyclization of aryl propynoates to form coumarins and benzocoumarins. The complex [(ppy)PtCl(MeCN)] (5 mol %) was the most active and efficient catalyst for such reaction, especially in the presence of AgSbF6 (15 mol %) in 1,2-dichloroethane. With this catalytic system, a wide range of substituents and functional groups proved compatible with the cyclization process, leading to a large variety of substituted coumarins and benzocoumarins (22 examples, 77-99%) (C) 2020 Elsevier Ltd.

Phosphite-based Au(i) catalytic systems containing an array of structurally diverse polyether-based regulation sites were designed and synthesised. These catalysts have been successfully tested in the Au(i)-catalysed C-H functionalisation of phenols and related derivatives with gold-carbenes derived from diazo compounds. Regulation of the steric congestion around the catalytic Au(i) centreviaion-dipole interactions with an external regulation agent led to an enhancement of both the activity and selectivity of the reaction. This new approach in supramolecular gold(i) catalysis has been applied to the derivatisation of an array of substituted phenols and related substrates and to the preparation of an advanced synthetic intermediate of the anticancer agent tamoxifen. The effects of the regulation agent on the selectivity and yield of the reaction have been studied and rationalised using DFT-D calculations.

Hepatocellular carcinoma (HCC) is one of the most prevalent cancers worldwide. Nowadays, pharmacological therapy for HCC is in urgent needs. Paclitaxel is an effective drug against diverse solid tumors, but commonly resisted in HCC patients. We recently have disclosed that microtubule affinity-regulating kinase 4 (MARK4) increases the microtubule dynamics and confers paclitaxel resistance in HCC, suggesting MARK4 as an attractive target to overcome paclitaxel resistance. Herein, we synthesized and identified coumarin derivatives 50 as a novel MARK4 inhibitor. Biological evaluation indicated compound 50 directly interacted with MARK4 and inhibited its activity in vitro, suppressed cell viability and induced apoptosis of HCC cells in a MARK4-dependent manner. Importantly, compound 50 significantly increased the drug response of paclitaxel treatment to HCC cells, providing a promise strategy to HCC treatment and broadening the application of paclitaxel in cancer therapy.

Human African trypanosomiasis (HAT), caused by the parasitic protozoa Trypanosoma brucei, is one of the fatal diseases in tropical areas and current medicines are insufficient. Thus, development of new drugs for HAT is urgently needed. Leucyl-tRNA synthetase (LeuRS), a recently clinically validated antimicrobial target, is an attractive target for development of antitrypanosomal drugs. In this work, we report a series of alpha-phenoxy-N-sulfonylphenyl acetamides as T. brucei LeuRS inhibitors. The most potent compound 28g showed an IC50 of 0.70 mu M which was 250-fold more potent than the starting hit compound 1. The structure-activity relationship was also discussed. These acetamides provided a new scaffold and lead compounds for the further development of clinically useful antitrypanosomal agents. (C) 2019 Elsevier Masson SAS. All rights reserved.

An approach for the calculation of the vaporization enthalpies of aromatic and heteroaromatic compounds at T = 298.15 K with accuracy competitive with experiment was proposed. The vaporization enthalpies may be calculated from the solution enthalpies of liquid and solvation enthalpies in benzene. The solution enthalpies of liquids were shown to be constant within a given type of aromatic compounds. For a set of 67 liquid and 41 solid aromatic and heteroaromatic compounds not capable of intermolecular hydrogen bonding, it was experimentally demonstrated that the solution enthalpies of liquids or supercooled liquids in benzene were equal to 1 +/- 1 kJ . mol(-1). The way to consider intermolecular hydrogen bonding, e.g., in phenol, aniline, pyrrole derivatives, was also proposed. The methods for solvation enthalpy calculation were proposed previously. The calculated and literature vaporization enthalpies values of 415 aromatic and heteroaromatic compounds were compared. Average absolute deviation amounted to 1.3 kJ . mol(-1). The proposed approach is especially valuable for calculation of the vaporization enthalpies of low-volatile compounds, including those solid at T = 298.15 K. (C) 2020 Elsevier B.V.

Background: Glycogen synthase kinase-3 (GSK-3) is involved in the phosphorylation and inactivation of glycogen synthase. GSK-3 inhibitors have been associated with a variety of diseases, including Alzheimer’s disease (AD), diabetes type II, neurologic disorders, and cancer. The inhibition of GSK-3 beta isoforms is likely to represent an effective strategy against AD. Objective: The present work aimed to design and synthesize coumarin derivatives to explore their potential as GSK-3 beta kinase inhibitors. Methods: The through different synthetic methods were used to prepare coumarin derivatives. The GSK-3 beta activity was measured through the ADP-Glo (TM) Kinase Assay, which quantifies the kinase-dependent enzymatic production of ADP from ATP, using a coupled-luminescence-based reaction. A docking study was performed by using the crystallographic structure of the staurosporine/GSK-3 beta complex [Protein Data Bank (PDB) code: 1Q3D]. Results: The eleven coumarin derivatives were obtained and evaluated as potential GSK-3 beta inhibitors. Additionally, in silico studies were performed. The results revealed that the compounds 5c, 5d, and 6b inhibited GSK-3 beta enzymatic activity by 38.97-49.62% at 1 mM. The other coumarin derivatives were tested at 1 mM, 1 mu M, and 1 nM concentrations and were shown to be inhibitor candidates, with significant IC50 (1.224-6.875 mu M) values, except for compound 7c (IC50 – 10.809 mu M). Docking simulations showed polar interactions between compound 5b and Lys(85) and Ser(203), clarifying the mechanism of the most potent activity. Conclusion: The coumarin derivatives 3a and 5b, developed in this study, showed remarkable activity as GSK-3 beta inhibitors.

Density functional theory (DFT) at the SMD/M06-2X/def2-TZVP//SMD/M06-2X/LANL2DZ(d),6-31G(d) level was used to explore the regioselective double oxidation of phenols by a hypervalent iodine(v) reagent (IBX) to give o-quinones. The oxidative dearomatization commences with the ligand exchange between IBX and phenol, yielding a phenolate complex, followed by the first redox process, which reduces iodine(v) to iodine(iii). Both the processes (the ligand exchange and the first redox reaction) were found to be mediated by a less stable isomer of iodine(v) species. We found that although the first redox process preferentially proceeds via an associative pathway, an electron withdrawing substituent on the phenol ring decreases its accessibility. The inspection of the electronic structure of the redox transition state indicates that the phenolate involved in the iodine(v) reduction has some phenoxenium character. The intrinsic stability of a phenoxenium ion is calculated to be highly sensitive to the substituent on the phenol ring. Since the electron withdrawing substituents considerably decrease the stability of the phenoxenium, they render the iodine(v) to iodine(iii) reduction energy consuming. Once the first redox step has completed, a catechol-iodine(iii) complex is formed, from which the second redox process produces the final o-quinone product via a carboxylate-assisted transition structure. This transition structure gains stability by hydrogen bond interaction between the catechol OH and carboxylate group. Such an interaction results in the phenolate not having any phenoxenium character in the transition structure, thus making the activation barrier to the second redox step independent from the substituent on the phenol ring.

Historical stringed musical instruments are a unique class of cultural heritage objects. Crafted during the 16th-18th centuries, these instruments remain somewhat mysterious. Due to the absence of written historical documents of traditional varnish recipes, their chemical characterization is the only way to recover the lost ‘secret’ of the Cremonese stringed instrument maker Antonio Stradivari and his contemporaries, whose traditions had been lost by 1800. Pyrolysis combined with gas chromatography-mass spectrometry (GC-MS) using solid-phase microextraction (SPME) followed by on-fiber silylation (Py SPME Syl GC-MS) was applied to a large collection of standards to evaluate its validity for compositional analysis and material identification of historical stringed instrument varnishes. The standards included pure resins (colophony, amber, mastic, sandarac, elemi), different types of shellac, as well as colorants or additives such as madder, dragon’s blood, and Aloe vera powder, and other materials (propolis, beeswax). The aim was to obtain an extensive collection of GC-MS data of silylated pyrolysis products useful for the characterization of the finishes of these unique historical objects. A set of distinct pyrolysis patterns and products were chosen as specific molecular markers for each standard. The method was applied to instrument varnish samples from Stainer, Baioni, Amati, Guarneri, Gasparo da Salo, Maggini, and Guadagnini instruments. The method was shown to be effective for the identification of oxidized lignin, drying oils, and diterpenic resins. In the case of dragon’s blood, madder, shellac, and propolis new markers were identified, suggesting their presence in some instrument varnishes. The identification of proteins and madder appeared most challenging.

Bronsted acid-catalyzed addition of the chiral N,N’-dioxide into ynamides generated enolonium ions in situ which underwent enantioselective alkylation by indoles, pyrroles, and phenols, without racemization of the formed tertiary center. This external oxidant approach allows for the use of unmodified nucleophiles and does not leave trace groups from the oxidant, which significantly increases the synthetic efficiency and the product diversity. Furthermore, the byproduct of the N,N’-dioxide could be efficiently recycled into an optically pure form.
