Longitudinal Tracking of Astrocyte Reactivity During the Development of Chronic Orofacial Neuropathic Pain Using [18F]‐SMBT‐1 Positron‐Emission Tomography

open access: yesGlia, Volume 74, Issue 8, August 2026.
Using [18F]‐SMBT‐1 PET, we longitudinally tracked MAO‐B–expressing reactive astrocytes during orofacial neuropathic pain development in rats, revealing region‐ and time‐specific astrocyte activation during pain chronification. ABSTRACT Chronic neuropathic pain represents a significant global health burden and is hypothesized to be maintained by an ...

Single‐Atom Iron‐Catalyzed Oxidative Esterification: From Methylarenes to the Upcycling of Polystyrene and Lignin‐Derived Feedstocks

open access: yesAngewandte Chemie, Volume 138, Issue 31, 27 July 2026.
Heterogeneous iron‐catalyzed environmentally benign and sustainable CH‐oxidative esterification methodology has been developed for the synthesis of esters. This challenging reaction has been achieved by the rational design of specific single atom iron‐based catalyst with Fe‐N4 active centers, which empowered the oxidative esterification of methyl and ...

The X‐Ray Crystal Structure of BorF, the Flavin Reductase Subunit of a Two‐Component Flavin‐Dependent Tryptophan Halogenase

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 94, Issue 8, Page 1529-1540, August 2026.
ABSTRACT BorF is a short‐chain flavin reductase from a desert soil bacterium that uses NADH to reduce FAD to FADH2, which is used by the tryptophan‐6‐halogenase BorH to chlorinate tryptophan in the biosynthetic pathway of borregomycin A. The X‐ray crystal structure of BorF bound to FAD was solved to 2.37 Å by molecular replacement.

The Pharmacology of the SLC15A4‐TASL Complex, an Emerging Target for the Treatment of Lupus

open access: yesPharmacology Research &Perspectives, Volume 14, Issue 4, August 2026.
ABSTRACT SLC15A4 is a member of the solute carrier superfamily that has been strongly linked to the pathogenesis of the auto‐immune disease SLE. The endo‐lysosomally localized SLC15A4 has traditionally been considered a proton‐dependent histidine and peptide transporter, but has also been shown to facilitate TLR7, 8, and 9 induced IFN‐alpha signaling ...

Three-Component Synthesis of 2‑Substituted Quinolines and Benzo[f]quinolines Using Tertiary Amines as the Vinyl Source [PDF]

open access: yes
A metal-free method for the construction of 2-substituted quinolines and benzo­[f]­quinolines from aromatic amines, aldehydes, and tertiary amines has been demonstrated. Cheap and readily available tertiary amines acted as the vinyl source.

Von Richter Cinnolines Synthesis Revisited—Approach to Polysubstituted Cinnoline Derivatives as Important Scaffolds for Kinase Inhibitors

open access: yesChemistrySelect, Volume 11, Issue 29, 3 August 2026.
A revised von Richter cyclization of 2‐aminoalkyne precursors enables the synthesis of polysubstituted 4‐halocinnoline derivatives. By addressing the key challenge of hydrolytic instability, this catalyst‐free approach delivers scaffolds amenable to late‐stage C‐4 functionalization.

Occurrence and Washout of Health‐Hazardous Chemicals in Children's Clothing

open access: yesContact Dermatitis, Volume 95, Issue 2, Page 148-158, August 2026.
A survey of 60 children's garments from the Swedish market showed a varying, often highly complex chemical content. The highest levels were generally found in synthetic materials and the lowest in light‐coloured cotton. Further, the washout effect by laundry and sweat migration of textile chemicals was investigated.

Risk Assessment Models for Heated Tobacco Products

open access: yesRisk Analysis, Volume 46, Issue 8, August 2026.
ABSTRACT Heated tobacco products (HTPs) are marketed as alternatives to conventional cigarettes with a potential reduced risk profile. Yet, their actual impact on cancer and noncancer disease risk remains uncertain and requires rigorous quantitative assessment.

Synthesis and Biological Evaluation of Triazolo[4,5-g]quinolines, Imidazo[4,5-g]quinolines and Pyrido[2,3-g]quinoxaline. Part II [PDF]

open access: yes, 2003
Synthesis of triazolo[4,5-g]quinolines, imidazo[4,5-g]quinolines and pyrido[2,3-g]quinoxaline has been described. Antimycobacterial, antibacterial and antimycotic activity were also reported.

Acyclic Hydrocarbon α,ω‐Dienes: From Biomass and Plastic Upcycling to Carbocycles, Precision Polymers, and Cross‐Linked Elastomers

open access: yesChemSusChem, Volume 19, Issue 14, 29 July 2026.
Hydrocarbon α,ω‐dienes are mainly produced from steam‐cracking derivatives, but high costs, complexity, and environmental impact limit their use. This review highlights sustainable paths from biomass and plastic upcycling, and surveys catalytic transformations into carbocycles and specialty polymers, emphasizing their role as modular building blocks ...
