The asymmetric functionalization of C-H is one the most attractive strategies in synthesis. In past decades, catalytic enantioselective C(sp3)-H has been intensively studied and successfully applied various bond formations, whereas alkylation was not well developed. Photoredox catalysis recently emerged as an efficient way to synthesize organic compounds under mild conditions. Despite many photoinduced stereoselective reactions that have achieved, related C(sp3)-C(sp3) coupling challenging,...
The glycosylative modification of peptides could improve the pharmacological properties peptide drugs and deliver them efficiently to target sites. Compared with O-/N-glycosides, C-glycosides exhibit more metabolic stability. We here disclose first example visible-light-promoted Cu-catalyzed stereoselective C-glycosylation. mild reaction conditions are compatible various carbohydrate substrates, as demonstrated a series monosaccharides disaccharide, amenable synthesis wide variety...
Alkylnitriles play important roles in many fields because of their unique electronic properties and structural characteristics. Incorporating cyanoalkyl with characteristic spectroscopy reactivity into amino acids peptides is special interest for potential imaging therapeutic purposes. Here, we report a copper-catalyzed asymmetric cyanoalkylation C(sp3)-H. In the reactions, glycine derivatives can effectively couple various cycloalkanone oxime esters high enantioselectivities, reaction be...
Background: Ionic liquids (ILs) are considered as green solvents, and widely applied for the extraction of various compounds. Methods: The present research focuses on flavonoids from Apocynum venetum L. leaves by ultrasound-assisted (UAE). Several major influencing factors were optimized. Then, an aqueous biphasic system (ABS) was further isolation flavonoids. Results: mainly distributed in top phase, while impurities extracted to bottom phase. parameters extraction, namely type...
In this article, we report on an experimentally generated soliton and bound-state passively mode-locked erbium-doped fiber laser by incorporating a saturable absorber (SA) made of MoS2/fluorine mica (FM) that was fabricated with the Langmuir–Blodgett (LB) method. The FM substrate is 20 μm thick easy to bend or cut, like polymer. However, it has higher damage threshold better thermal dissipation than polymers. addition, LB method can be used fabricate thin film good uniformity. study,...
In this work, a two-step extraction methodology of ionic liquid-based ultrasonic-assisted (IL-UAE) and aqueous two-phase system (IL-ATPS) was developed for the purification secoisolariciresinol diglucoside (SDG) from flaxseed. IL-UAE step, several kinds ILs were investigated as extractants, to identify IL that affords optimum yield. The conditions such concentration, ultrasonic irradiation time, liquid–solid ratio optimized using response surface (RSM). IL-ATPS ATPS formed by adding...
A colorimetric and ratiometric fluorescent probe shows a fast response high selectivity towards sulfite with low detection limit (12 nM).
An anthracene carboxyimide-based fluorescent probe was developed for rapid detection of formaldehyde in living cells with high sensitivity and selectivity.
Bisphenols are environmental toxins with endocrine disruptor activity, yet bisphenol A (BPA) and its analogs still widely used in manufacturing plastic products. There is evidence showing that BPA elicits inflammation humans animals, but the target cell types of not well understood. In this study, we sought to determine BPA’s direct effect on macrophages immunotoxicity mouse intestine. Ghrelin an important nutrient-sensing hormone, acting through receptor growth hormone secretagogue (GHSR)...
(1) Background: Ionic liquids (ILs) are considered "green" solvents and have been widely used in the extraction separation field recent years; (2) Methods: In this study, some common ILs functionalized magnetic ionic (MILs) were as adjuvants for solvent of paclitaxel from Taxus x media (T. media) using methanol solution. The conditions concentration, IL type amount, solid-liquid ratio, temperature, ultrasonic irradiation time investigated single factor experiments. Then, three factors...
Anion-exchange resin (AER) and choline chloride-based deep eutectic solvent-modified anion-exchange (DES-AER) were prepared, their performance properties assessed by Fourier transform infrared spectrometer (FTIR), field emission scanning electron microscopy (FE-SEM), adsorption experiments. In addition, the separation characteristics on solid-phase extraction (SPE) cartridges packed with octadecyl silica (ODS), AER, DES-AER for rapid of cleistanthol from Phyllanthus flexuosus extracts have...
In this work, a biological engineering-based biosilica-yeast hybrid material was developed. It obtained by the aggregation of Yarrowia lipolytica through biosilicification catalyzed using genetically displayed silicatein on its cell surface. With orthosilicate or seawater as substrate, silicatein-displayed yeast could aggregate into flocs with flocculation efficiency nearly 100%. The resulting floc found to be sheetlike formed biosilica-mediated immobilization cells via cross-linking and...
