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

Metabolomic analysis reveals the molecular mechanism related to leg abnormality in broilers

Animal Research and One Health, EarlyView.
The graphical abstract shows the principal results of this study. Compared to the leg normal broilers, the serum calcium to phosphorus ratio was extremely decreased in the group with deformed leg bones. Additionally, a total of nine differential metabolites significantly associated with leg abnormalities and serum calcium and phosphorus levels were ...

Photoallylation Mechanism of Dicyanobenzenes with Allyltrimethylsilane in Solution Investigated by Cold UV and IR Spectroscopy in the Gas Phase

Chemistry – An Asian Journal, EarlyView.
The structure of the chemical intermediate in photoallylation of dicyanobenzenes (DCBs) with allyltrimethylsilane (ATMS) in acetonitrile was determined by cold UV and IR spectroscopy in the gas phase. The reaction mechanism was discussed on the basis of the intermediate structure. It was found that the elimination of a CN group from the intermediate is

Engineering Photolabile Cyclopentane‐Fused Coumarins: From One‐Pot Synthesis to Mechanistic Study for Visible Light‐Triggered Photolysis

Chemistry – An Asian Journal, EarlyView.
Cyclopentane fusion in coumarin photocages transforms their behavior from rapid SN1‐mediated release (minutes) to a slower elimination pathway (hours), accompanied by dramatic spectral changes upon photolysis, providing complementary tools for controlled‐release applications requiring different payload delivery rates.

Novel Sulfonylhydrazones With Sulfonate Ester Framework: Promising Dual Inhibitors of AChE and hCAs

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Alzheimer's disease (AD) is a progressive neurodegenerative disorder that affects millions of individuals worldwide. Treatment strategies for AD vary depending on cognitive and behavioral symptoms, with cholinergic replacement therapy using acetylcholinesterase (AChE) inhibitors being one of the primary approaches.
