Switchable Magnesium Catalysis: Dehydrogenative Borylation Versus Hydroboration of Terminal Alkynes

open access: yesChemistryEurope, Volume 4, Issue 3, March 2026.
Magnesium at the centre: A switchable magnesium catalyst enables selective dehydrogenative borylation or hydroboration of terminal alkynes. Organoboranes are key intermediates in modern synthetic chemistry, yet their preparation often relies on precious metal catalysts and multistep protocols.

Sol-gel immobilization of glutathione transferase: efficient tool for bioremediation [PDF]

open access: yes, 2015
Glutathione transferases are multi-functional enzymes with an important role in xenobiotic detoxification. They catalyse the nucleophilic addition of the sulfur atom of glutathione (γ-L-Glu-L-Cys-Gly, GSH) to the electrophilic groups of a large variety ...

Dietary Bioactives and Physical Activity in the Regulation of Hippocampal Neurogenesis and Cognitive Decline

open access: yesFood Science &Nutrition, Volume 14, Issue 3, March 2026.
Exercise and dietary polyphenols enhance hippocampal plasticity and cognitive function via complementary molecular mechanisms. Central pathways include BDNF signaling, inflammation control, and mitochondrial regulation. Although synergy is mainly supported by preclinical data, lifestyle‐based strategies show promise for brain health maintenance ...

Carbon xerogel supported noble metal catalysts for fine chemical applications [PDF]

open access: yes, 2008
Carbon xerogel, a mesoporous material, was produced by polycondensation of resorcinol and formaldehyde. A concentrated nitric acid solution was subsequently used to introduce high amounts of oxygenated groups on the surface.

Linking Nutritional, Sensory, and Functional Quality in Plant‐Based Proteins Through Structural Modification and Computational Insights

open access: yesSustainable Food Proteins, Volume 4, Issue 1, March 2026.
The lacking essential amino acids, low digestibility, bioavailability, bitterness, and presence of anti‐nutritional factors that limit the consumption of plant proteins and their use in food formulations are discussed comprehensively. The findings of recent studies on novel technologies and computer‐based applications used to cope with these challenges

Indanone Building Blocks From Lignin Related C9‐Platform Molecules

open access: yesChemistrySelect, Volume 11, Issue 10, 11 March 2026.
ABSTRACT Lignin‐based aryl 3‐hydroxypropanones were converted into indanones via a domino dehydration/Nazarov cyclization in the presence of a superacid. The cyclization was studied in detail, and the resulting indanones were engaged in two postfunctionalizations: a reduction/elimination domino sequence and a ring expansion. Lastly, the method has been

Syntheses of Isoxazoline-Based Amino Acids by Cycloaddition of Nitrile Oxides and Their Conversion into Highly Functionalized Bioactive Amino Acid Derivatives [PDF]

open access: yes, 2012
The present account illustrates the syntheses of isoxazoline- based amino acids by the cycloaddition of 1,3-dipolar nitrile oxides to the C–C double bond of unsaturated amino acid derivatives, with focus on the regio- and stereoselectivities of the ...

A Chemiluminescence‐Activated Photodynamic Platform to Penetrate MRSA Biofilms and Counteract H2S‐Mediated Defense

open access: yesSmall Science, Volume 6, Issue 3, March 2026.
A chemiluminescence‐activated photodynamic system is developed to eradicate methicillin‐resistant Staphylococcus aureus (MRSA) biofilms without external light or antibiotics. CO2 generated in situ disrupts biofilms and propels nanocarriers for deep penetration, while hypericin generates reactive oxygen species and suppresses H2S‐mediated defenses. This
