Impact of Species, Growth Conditions, and Plant Processing on the Phytochemistry and Antimicrobial Activity of Agrimonia Extracts

Chemistry &Biodiversity, EarlyView.
Agrimony is a medicinal herb known for its content of polyphenols and beneficial bioactivity, both of which can be strongly influenced by cultivation and processing. This study reveals that agrimony plant structures, species, and postharvest processing are the main drivers of observed variability in both phytochemical composition and antimicrobial ...

Multifaceted Study of Medicago marina Essential Oil: Chemical Composition, Antidiabetic, and Phytotoxic Insights via In Vitro and In Silico Approaches

Chemistry &Biodiversity, EarlyView.
ABSTRACT The essential oil of Medicago marina was subjected to analysis at vegetative and reproductive stages of development, with a particular emphasis on its chemical composition, α‐amylase inhibition, and allelopathic activities. The results of the gas chromatography and molecular docking studies demonstrated alterations in oil yield and composition

Reactivity of Carbohydrate Phosphodiesters, Potential Targets of Antibacterial Agents

Chemistry &Biodiversity, EarlyView.
A simple carbohydrate phosphodiester model was synthesized to compare the reactivity of phosphodiester bonds within carbohydrates and RNA. ABSTRACT While monosaccharide units in bacterial carbohydrates may be linked with phosphodiester bonds, human carbohydrates exclusively contain glycosidic linkages.

Hydration of vinyl ether groups by unsaturated glycoside hydrolases and their role in bacterial pathogenesis [PDF]

, 2008
Many pathogenic microorganisms invade mammalian and/or plant cells by producing polysaccharide-degrading enzymes (lyases and hydrolases). Mammalian glycosaminoglycans and plant pectins that form part of the cell surface matrix are typical targets for ...

A Purification‐Free Strategy for the Electrochemical Oxidation of the Primary Hydroxy Group in Glycopyranosides

ChemElectroChem, EarlyView.
A straightforward protocol for the electrochemical oxidation of the primary hydroxy group in glycopyranosides is presented. It uses aqueous ammonia as a base and electrolyte, reticulated vitreous carbon (RVC) electrodes, and TEMPO as a mediator. The ammonium salts of the corresponding uronic acids are obtained in excellent yield upon evaporation of the

Synergistic Gold‐Silicon Catalysis: Unravelling Alkynyl Gold Reactivity and Application to the High‐Performance C‐Alkynylation of Glycals

Chemistry – A European Journal, EarlyView.
This research highlights an efficient and highly α‐stereoselective Au‐Si‐catalyzed alkyne transfer reaction from 1‐trimethylsilylalkynes to glycals, utilizing the bench‐stable (F5Ph)3PAuNTf2 complex at low catalyst loadings (0.2–1 mol%). DFT mechanistic investigations revealed the nucleophilic character of the in situ formed electron‐deficient ...
