4,6‐O‐Phenylboronic Ester Protection for 1,2‐cis‐α‐Selective Glucosylation

Asian Journal of Organic Chemistry, EarlyView.
The 4,6‐O‐phenylboronic ester protection for 1,2‐cis‐α‐selective glucosylation, previously reported by the Crich group, was revisited and the stereodirecting effect of the cyclic protecting group was unveiled. 4,6‐O‐Phenylboronic ester‐protected glucosyl and 2‐azido‐2‐deoxyglucosyl donors exhibited higher α‐selectivity of the glucosylation than the ...

Metabolic labelling of cholesteryl glucosides in Helicobacter pylori reveals how the uptake of human lipids enhances bacterial virulence. [PDF]

, 2016
Helicobacter pylori infects approximately half of the human population and is the main cause of various gastric diseases. This pathogen is auxotrophic for cholesterol, which it converts upon uptake to various cholesteryl α-glucoside derivatives ...

Identification of bioactive compounds and molecular targets of Fuke Huahuang formulation to treat vaginitis

Animal Models and Experimental Medicine, EarlyView.
Fuke Huahuang formulation (FHF) is used to treat vaginitis, and it exerts a promising anti‐inflammatory effect in clinical use. However, the detailed components and mechanisms of FHF for treating vaginitis remain unreported, and further preclinical evaluation is required to reveal its potential pharmacological activities against vaginitis.

Daidzein and genistein but not their glucosides are absorbed from the rat stomach [PDF]

, 1999
Absorption of isoflavone aglycones and glucosides was compared in rats. Daidzein, genistein, daidzin and genistin were orally administered at a dose of 7.9 μmol/kg in 25 mM Na2CO3 and next their metabolite concentration in blood plasma was monitored for ...

An Update: Enzymatic Synthesis for Industrial Applications

Angewandte Chemie International Edition, EarlyView.
Biocatalysis has become a sustainable and cost‐competitive alternative to established chemical synthesis, enabling the enzyme‐based production of not only commodity chemicals but (non‐natural) amino acids, (rare) sugars, as well as synthetic nucleotides.

Greek Protected Designation of Origin Xinomavro Wines: A Deep Dive into Their Chemical Composition and Geographical Origin by Using Ultra High Performance Liquid Chromatography–Trapped Ion Mobility Spectrometry–Quadrupole Time of Flight–Mass Spectrometry

Analysis &Sensing, EarlyView.
Greek protected designation of origin Xinomavro wines are analyzed with ultra high performance liquid chromatography–trapped ion mobility spectrometry–quadrupole time of flight‐mass spectrometry (UHPLC‐TIMS‐QTOF‐MS). Both target and not‐target screening approaches are employed, leading to the identification and quantification of several polyphenols and

Detergent/surfactant retention during ultrafiltration in the formulation of biotherapeutics

Biotechnology Progress, EarlyView.
Abstract Surfactants like polysorbate (Tween®) are commonly used as excipients in the production of monoclonal antibodies and other recombinant proteins. The retention behavior of these excipients in the final ultrafiltration step can be difficult to predict due to the presence of both monomers and micelles.
