This study aimed to characterize the antioxidant potential, bioactive and volatile compounds of the stones from fruits of Cornus mas. Both fresh and roasted stones show a high antioxidant potential (166.48-509.74 mu mol TE/g dw stones), which significantly depends on the cultivars. The roasted stones preserved 43.6% (DPPH; ‘Raciborski’) to 97.2% (FRAP; ‘Alesha’) of the antioxidant activity of the non-roasted stones. In the stones, two iridoids and ellagic acid were determined. During roasting, loganic acid remained stable, whereas cornuside was completely degraded. The analyses showed a 30-fold increase in the concentration of ellagic acid and in the formation of two of its derivatives. The major aroma compound of the roasted stones was furfural, but we also identified 18 pyrazine derivatives. This study is the first attempt to valorize Cornelian cherry stones via roasting. The roasted stones can be a coffee substitute, or aromatic and bioactive additions to cereal coffees.

Cerebral amyloid angiopathy (CAA) commonly found in the aged is pathologically characterized by beta-amyloid (A beta) deposition in the walls of arteries and capillaries of brain. In this study, four flexible multidentate benzyldiamine derivatives as potential probes for cerebrovascular A beta deposition were designed and synthesized. In in vitro inhibition assays, the ligands 18-21 displayed high affinities for A beta aggregates with K-i values of 1.45 +/- 0.53 nM, 1.68 +/- 0.35 nM, 1.16 +/- 0.23 nM and 1.72 +/- 0.19 nM, respectively. A significant improvement in the binding affinity over the monomer, compounds 9-12 or benzyldiamine derivatives, demonstrated the applicability of the multidentate approach. The underlying mechanism of these novel A beta agents was explored by molecular docking technique, which theoretically verified the high affinities of the multidentate benzyldiamine derivatives for A beta aggregates. Moreover, the molecular masses of the ligands 18-21 are more than 700 Dalton, which are believed to be hardly capable of penetrating blood brain barrier. In this regard, these ligands could be used to distinguish CAA from Alzheimer’s disease which is another A beta-related disorder disease.

A postpolymerization nucleophilic aromatic substitution reaction is used as a strategy to efficiently diversify conjugated polymers. Conjugated polymers and small molecular models bearing tetrafluorophenyl and octafluorobiphenyl units are reacted with thiophenol derivatives, phenol derivatives, and carbazole in the presence of bases. Model reactions provide insights into the reactivity, numbers and patterns of substitution, structural features, and spectroscopic data. Thiophenol derivatives and carbazole achieve complete substitution of fluorine atoms in both the polymer and the model reactions, whereas phenol derivatives result in disubstitution in each arene ring with para-selectivity. The highly twisted and structurally rigid main chain structures are confirmed for a fully substituted arene motif in both the polymers and the models, resulting in the formation of syn- and anti-atropisomer or axial chirality and in the twisted intramolecular charge transfer character. The obtained polymers and models show unique optical and electrochemical properties, including phosphorescence at low temperatures in the case of the sulfur-containing materials.

Cao, HJ; Wang, KK; Yang, ZQ; Wu, SJ; Han, DD in [Cao, Haijie; Wang, Kuikui; Yang, Zhengqiang; Wu, Shijie] Qingdao Univ, Coll Mat Sci & Engn, Inst Mat Energy & Environm, Qingdao 266071, Peoples R China; [Han, Dandan] Heze Univ, Sch Chem & Chem Engn, Heze 274015, Peoples R China published Quantum chemical study on the ozonolysis mechanism of guaiacol and the structure-reactivity relationship of phenols with hydroxyl, methoxy, and methyl substituents in 2021.0, Cited 37.0. Recommanded Product: 150-76-5. The Name is Mequinol. Through research, I have a further understanding and discovery of 150-76-5.

Quantum chemical calculations with the M06-2X method were performed to uncover the ozonolysis mechanism of guaiacol and several hydroxylated, methoxylated, and methylated phenols to improve the understanding of the ozone-induced attenuation of phenolic compounds. The detailed kinetic properties were obtained by the transition state theory (TST) and the Rice – Ramsperger – Kassel – Marcus (RRKM) theory. Results confirm that the primary ozonides originated from guaiacol occupy considerably long retention time than the short-lived primary ozonides formed from vinyl-type compounds in the air. The TST rate constant of guaiacol ozonolysis is calculated with a value of 8.81 x 10-20 cm3 molecule-1 s-1 at room temperature. The RRKM results prove that the rate constant is positively dependent on temperature but shows no relation with pressure. The reactivity of substituted phenols exhibits a strong correlation with the ozone affinity of carbon atoms and the orbital energy difference (ELo-Hac) between the lowest unoccupied molecular orbital of O3 and the highest occupied molecular orbital of phenols. The substituents can reduce the value of ELo-Hac and improve the phenols’ reactivity, especially when they locate at the ortho- and para-position. The substituents also improve the ozone affinity of carbon atoms due to the electron-withdrawing effect. The methyl group delivers a moderate impact on the reactivity compared to hydroxyl and methoxy groups.

In the search for novel aromatase inhibitors, a series of triazole and imidazole-based carbamate derivatives were designed and synthesized. Final compounds were thus evaluated against human aromatase by in vitro kinetic experiments in a fluorimetric assay in comparison with letrozole. The effect of most active derivatives 13a and 15c was then evaluated in vitro on the human breast cancer cell line MCF7 by MTT assay, cytotoxicity assay (LDH release) and cell cycle analysis, revealing a dose-dependent inhibition profile of cell viability and low micromolar IC50 values. In addition, docking simulations were also carried out to elucidate at a molecular level of detail the binding modes adopted to target human aromatase. (C) 2020 Elsevier Masson SAS.

We report an enantio- and diastereoselective, complete hydrogenation of multiply substituted benzofurans in a one-pot cascade catalysis. The developed protocol facilitates the controlled installation of up to six new defined stereocenters and produces architecturally complex octahydrobenzofurans, prevalent in many bioactive molecules. A unique match of a chiral homogeneous ruthenium-N-heterocyclic carbene complex and an in situ activated rhodium catalyst from a complex precursor act in sequence to enable the presented process.

Direct oxidative coupling of different inert C-H bonds is the most straightforward and environmentally benign method to construct C-C bonds. In this paper, we developed a Pd-catalyzed intramolecular oxidative coupling between unactivated aliphatic and aryl C-H bonds. This chemistry showed great potential to build up fused cyclic scaffolds from linear substrates through oxidative couplings. Privileged chromane and tetralin scaffolds were constructed from readily available linear starting materials in the absence of any organohalides and organometallic partners.

We have developed a supramolecular (close form) [2]pseudorotaxane polymer containing the green-emissive (lambda(em) = 523 nm) BODIPY-based pillar[5]arene host and the non-emissive spiropyran (SP)-based cyano guest (close form), which can be converted to a red-emissive (lambda(em) = 630 nm) merocyanine (MC)-based guest (open form) upon UV exposure as well as turned into a bi-fluorophoric host-guest polymer with ratiometric PL emission of Forster resonance energy transfer (FRET) behavior in THF/water solution (60% H2O, v/v). The equal host-guest molar ratio and the formation of the [2]pseudorotaxane polymer can be further verified using H-1 NMR titration, Job’s plot analysis, DOSY and ITC experiments. Hence, the bi-fluorophoric host-guest (with the MC open form) polymer possessed the highest red-emission of the MC acceptor, which was also confirmed using TRPL measurements to possess the shortest lifetime of 0.37 ns and the best FRET efficiency of 83.5%. Since the MC unit could react with CN- to induce a non-emissive quenching process, the mono-fluorophoric guest would show turn-off PL behavior and detect cyanide ions with a corresponding limit of detection (LOD) value of 0.94 mu M. In comparison, the optimal LOD value of 0.48 mu M toward CN- anion could be achieved by our bi-fluorophoric host-guest polymer via the FRET-OFF process. Therefore, cyanide detection and cell viability tests using the open form of the [2]pseudorotaxane polymer suggest useful bio-imaging applications in living cells.

A newly developed robust catalyst [Ir(COD)(Phen)Cl] (A) was used for the C-H borylation of three dozen aromatics and heteroaromatics with excellent yield and selectivity. Activation of the catalyst was identified by the use of catalytic amounts of water, alcohols, etc., when B(2)pin(2) was used in noncoordinating solvents, while for THE catalytic use of HBpin was required. The results were on par with the in situ based expensive system [Ir(OMe)(COD)](2)/dtbbpy or Me(4)Phen.
