Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

open access: yesThe Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...

Dendritic Cell α‐Ketoglutarate Regulates Tfh Polarization in Allergy

open access: yesAllergy, EarlyView.
Allergen induces a dendritic cell metabolism shift toward glutaminolysis with α‐ketoglutarate as a regulator of Tfh subset polarization. Glutaminolysis is required for DC allergen uptake, co‐stimulatory molecule expression, and CLR expression. Modulation of glutaminolysis, JmjD3 histone demethylation, or HIF‐1α degradation alters Tfh polarization and ...

Defining the role of αC helix interactions in the activation of the integrin αI domain

open access: yesThe FEBS Journal, EarlyView.
The α2I domain of the α2β1 integrin contains a distinctive αC helix and a conserved Arg288‐Glu318 ion pair that stabilizes the closed state of the domain. Disruption of this ion pair in the activated α2I variant unwinds the αC helix, which allows interaction with additional collagen‐binding sites increasing collagen binding.

Ligações hidrogênio fortes em ácidos dicarboxílicos e diaminas aromáticas

open access: yesQuímica Nova, 2000
A very short-strong hydrogen bond (20kcal/mol) is found in the monoanion of certain dicarboxylic acids derived from maleic and dialkylmalonic acids. Certain aromatic diamines that are known as proton sponge have exceptionally high basicity (pKa) and are ...

Four Haylages, One Metabonome: Defining Diet Driven Metabolic Shifts in Ponies

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT Haylage is widely fed to all categories of stabled horses across Europe and New Zealand. Haylage can vary from high energy nutrient dense forage to low energy highly fibrous fodder, yet little is known about the impact different haylages have on metabolism in horses.

Advances in organic UV filters for sunscreens over the past decade

open access: yesPhotochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

Effects of cold water immersion versus active recovery on oxidative stress, redox gene expression and mitochondrial adaptations after strength training

open access: yesExperimental Physiology, EarlyView.
Abstract We compared the acute and chronic effects of postexercise cold water immersion (CWI) and active recovery (ACT) on oxidative stress, redox‐related gene expression, mitochondrial adaptations and muscle oxidative capacity. In a crossover study, nine males completed strength sessions, followed by either 10 min CWI or ACT.

Warburg redefined: Metabolites, mitochondria and macrophages in immune regulation

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Following pro‐inflammatory stimulation, macrophages undergo Warburg‐like metabolic rewiring that extends more than increased glycolysis. The non‐canonical functions of glycolytic enzymes and lactate accumulation control macrophage immune responses through multiple signalling pathways (a).

Self‐Assembled Monolayers on Gold Surfaces of Ferrocene‐BODIPY‐Fullerene‐Helical Peptide Conjugates: Studies of Electron Transfer Processes by Ultra‐Fast Electrochemistry

open access: yesJournal of Peptide Science, Volume 32, Issue 12, December 2026.
Three ferrocene‐BODIPY‐C60‐peptides (T1–T3) were synthesized and grafted on gold surfaces to form self‐assembled monolayers. Calculation of the tilt angles and surface density of these SAMs using PM‐IRRAS and ultrafast electrochemical experiments revealed that less vertically oriented and densely packed monolayers were obtained compared with previously

An Investigation Into the Yields of 3,4‐Methylenedioxyphenyl‐2‐propanone (MDP2P) From Glycidate Pre‐Precursors

open access: yesDrug Testing and Analysis, Volume 18, Issue 11, Page 1470-1479, November 2026.
Hydrolysis of the glycidate pre‐precursors MMDMG and EMDMG was evaluated for MDP2P production. Acid hydrolysis of MMDMG (HCl, 100°C, 18 h) yielded the highest MDP2P recovery (79%), whereas base hydrolysis produced only slightly lower yields (73%), demonstrating both pathways are effective routes to this key MDMA precursor.
