Preparation and chiral separation of a novel immobilized cellulose-based chiral stationary phase in high-performance liquid chromatography

open access: yes, 2012
The chiral selector 6-azido-2, 3-di(p-chlorophenylcarbamoylated) cellulose was synthesized and further chemically immobilized onto 5-μm amino functionalized spherical porous silica gel.

Analysis of Carbohydrates and Glycoconjugates by Matrix‐Assisted Laser Desorption/Ionization Mass Spectrometry: An Update for 2023–2024

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT The use of MALDI mass spectrometry for the analysis of carbohydrates and glycoconjugates is a well‐established technique and this comprehensive review is the twelfth update of the original article published in 1999 and brings coverage of the literature to the end of 2024.

Enantioselective Determination of Upadacitinib in Pharmaceutical Formulations Using Reversed‐Phase Chiral Liquid Chromatography [PDF]

open access: yesJ Sep Sci
A reversed‐phase chiral HPLC method was developed for the enantioselective separation and quantification of upadacitinib using a Box‐Behnken design. The validated method was successfully applied to the quantification of upadacitinib in a commercial tablet formulation, and its environmental impact and practicality were evaluated using various assessment

Advances in the Protective Effects and Mechanisms of β‐Aminoisobutyric Acid in Maintaining Multi‐Organ Homeostasis

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT β‐Aminoisobutyric acid (BAIBA) is an exercise‐responsive myokine/metabolite released by skeletal muscle and has attracted increasing interest as a potential exercise mimetic and therapeutic candidate in preclinical research. BAIBA acts locally in skeletal muscle and can also reach distal organs through the circulation, contributing to the ...

A walk in the park—Identifying healthy greenspaces using scents

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
As urbanisation accelerates globally, access to nature is increasingly recognised as vital for public health and wellbeing. We captured and analysed plant‐emitted airborne ‘scent signatures’ across Oxford's urban greenspaces to assess their potential health relevance.

The continuing significance of chiral agrochemicals

open access: yesPest Management Science, Volume 81, Issue 4, Page 1697-1716, April 2025.
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Synthesis and characteristics of the human serum albumin-triazine chiral stationary phase

open access: yes, 2000
Human serum albumin (HSA) was successfully bonded to silica with s-triazine as activator. The coupling reaction by this method was rapid and effective. The triazine-activated silica is relatively stable and can be installed for at least 1 month without ...

Enantioselective potential of sulfobutylether-β-cyclodextrin based chiral stationary phase [PDF]

open access: yes, 2018
The aim of this diploma thesis was to prepare two new chiral stationary phases by dynamic coating of sulphobutylether-β-cyclodextrin (SBE-β-CD) with varying degrees of substitution onto strong anion-exchange stationary phases.
