Copper porphyrin-catalyzed construction of ether bond by cross-dehydrogenative coupling of sp [3] C-H bond with phenols bearing electron-withdrawing groups (EWG) was described for the first time. A broad range of substrates afforded different acetals in moderate to excellent yields with good functional group tolerance. The developed method is not only suitable for phenol substrates with ortho-directing groups, but also suitable for those phenol without ortho-directing groups. Significantly, a high turnover number (TON) up to 7300 was achieved in gram-level test. (C) 2020 Elsevier Ltd. All rights reserved.

A near-infrared fluorescent probe plays an important role in biosensing and bioimaging because of its high efficiency, sensitivity and negligible background interference in vivo. Azobenzene derivatives demonstrate well-known sensitivity to light and are unique enzyme-responsive candidates in drug delivery and biological detection because the azo double bond can be cleaved by azoreductase. Herein, a novel near-infrared probe of an amphiphilic block copolymer with biological compatibility was synthesized. The azobenzene group attached with the near-infrared fluorescent group AzaBODIPY (boron-dipyrromethenes) linked the hydrophilic (PEG) and hydrophobic (PLA) segments to form the amphiphilic block copolymer PEG-AzaBODIPY-AZO-PLA. PEG(398)-AzaBODIPY-AZO-PLA(144) self-assembled into drug-loaded spherical micelles. The self-assemblies were non-fluorescent owing to the aggregation-induced quenching (ACQ) effect. Triggered by azoreductase, the PEG and PLA segments were disconnected due to the cleavage of the azo bond. This caused the disassembly of the micelles and the subsequent release of the encapsulated drug. Upon disassembly, the emission of the near-infrared fluorescence was activated by the elimination of the ACQ effect. Furthermore, the fluorescence intensity of the self-assemblies in solution increased continuously with drug release. The fluorescence reporting drug release demonstrates the potential applications in biosensing and controlled drug release in the colon of the human intestine.

Herein we report a novel and straightforward protocol for the construction of valuable gem-BPs by means of proton-coupled electron-transfer (PCET)-triggered enamido C(sp(2))-H diphosphorylation. This reaction represents a rare example of realizing the challenging double C-P bond formation at a single carbon atom, thus providing facile access to a broad variety of structurally diverse bisphosphonates from simple enamides under silver-mediated conditions. Initial mechanistic studies demonstrated that the diphosphorylation involves two rounds of PCET-initiated radical relay process.

The Name is 4′-Hydroxyacetophenone. Through research, I have a further understanding and discovery of 99-93-4.

The antioxidant activity of Sage leaf (SL) and Bay leaf (BL) extracts was studied. Both plants were extracted using water and ethanol at different concentration, and the antioxidant activity was measured by ABTS [2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic acid)] radical cation scavenging and reducing power (RP) methods. In both cases 60% and 80% ethanolic extracts of Sage and Bay leaves showed the highest activity and were incorporated into multilayer films. The initial concentration for 60% ethanolic extracts of Sage and Bay leaves to scavenge 50% of free radical ABTS were 5.67 +/- 0.26 mu g x mL(-1) and 18.68 +/- 0.16 mu g x mL(-1) respectively, whereas for 80% ethanolic extracts the concentrations were 7.96 +/- 0.02 and 14.65 +/- 0.59 mu g x mL(-1) respectively. The initial concentrations of ethanolic 60% extracts of Sage and Bay leaves to allow absorbance 0.5 for reducing power were 35.38 +/- 0.19 mu g x mL(-1) and 91.43 +/- 2.84 mu g x mL(-1) respectively, while for 80% ethanolic extracts of Bay and Sage leaves were 46.01 +/- 1.21 mu g x mL(-1) and 85.47 +/- 0.9 mu g x mL(-1) respectively. Then, the multilayer films were exposed to a gas stream enriched with free radicals to evaluate the free radicals scavenging. The new packaging with 60% ethanolic Sage extract exhibited the highest activity with low percentage of hydroxylation (69.64 +/- 6.86%) followed by that with 80% ethanolic extract for both Bay (85.49 +/- 5.3%) and Sage (87.09 +/- 3.93%) leaves extracts. The ability of two active packaging built with 60% ethanolic Sage extract and 80% ethanolic Bay extract to inhibit lipid oxidation of fried potatoes was studied by measuring secondary lipid oxidation products using thiobarituric acid reactive substances (TBARS). Significant lower value of Malondialdehyde (MDA) was obtained for fried potatoes stored in active packaging built with ethanolic 60% extract of Sage and 80% ethanolic extract of Bay leaves (0.342 +/- 0.01 and 0.392 +/- 0.02 mu g MDA x g(-1) respectively) at 40 degrees C for 20 days compared to the control (0.568 +/- 0.03 mu g MDA x g(-1)). Lipid oxidation decreased 40% and 31% for packaging with 60% Sage and 80% Bay ethanolic extracts respectively. The UPLC-MS-QTOF analysis of Sage and Bay leaves extracts revealed the presence of phenolic acids, tannins, flavonoids, and terpenoids. Migration tests from active materials demonstrated the absence of migration.

The phytochemical studies on the aerial parts of Digitalis davisiana Heywood led to the isolation of three undescribed phenylethanoid glycosides named as digidavisoside A (5), digidavisoside B (7), and davisoside (8), along with 9 known compounds, ferruginoside B (1), isolugrandoside (2), lugrandoside (3), maxoside (4), 3 ””-O-methylmaxoside (6), trans-lamiuside E (9), digiciliside B (10), p-hydroxyacetophenone (11), and chrysoeriol (12). For the first time compound 11 was reported for Digitalis genus. The chemotaxonomical significance of these compounds in Plantaginaceae family was evaluated and 3′-O-glucosyl substituted phenylethanoid glycosides 4-8 and 10 were found to be chemotaxonomically important for the family. Cytotoxic activity of the aqueous fraction of the methanolic extract was also tested against HEp-2 (human larynx epidermoid carcinoma) and HepG2 (human hepatocellular carcinoma) cancer cell lines. The aqueous fraction showed stronger cytotoxicity on HEp-2 cells than on HepG2. Therefore, the cytotoxic activity of 1-4, 6, 7 and 9 were tested against HEp-2 and L929 (mouse fibroblast cell) cell lines. Other isolated compounds could not be tested due to their insufficient amount. The results were evaluated in the point of structure-activity relationships. IC50 values against HEp-2 cells were established in a range of 71.9-220 mu M. Maxoside (4), isolugrandoside (2) and lugrandoside (3) showed higher cytotoxicity against HEp.2 cell line than other isolated compounds.
