Excited state aromatization assisted push-pull abilities of two unsaturated oxazolone derivatives

Journal of Saudi Chemical Society, 2018
Molecular structures of two unsaturated oxazolone derivatives involving furan rings, which are decorated with p-tolyl (FurM) and 4-nitro phenyl (FurN), were investigated by X-ray crystallography and quantum chemical calculations. Their ground and excited

Modular and Stereoselective Synthesis of Cyclobutane β‐Amino Alcohols

Angewandte Chemie International Edition, EarlyView.
Late‐stage functionalization and photoisomerization of 1,2‐azaborine leads to a general strategy for the synthesis of diversely substituted cyclobutane β‐amino alcohols. The relative stereochemistry of the resulting products is unambiguously defined by the stereospecific and stereoselective nature of the photoisomerization‐hydrogenation‐oxidation ...

Differential Roles for IL‐4Rα and IL‐13Rα1 in Immune Cell Infiltration and Epithelial Remodeling in Experimental Eosinophilic Gastritis

Allergy, EarlyView.
This study described the development of an experimental model for eosinophilic gastritis (EoG). Experimental EoG recapitulates histopathological features of human disease. including foveolar elongation, fibrosis, eosinophilia, mastocytosis and shared transcriptional programs.

Reactivity of (Z)-4-arylidene-5(4H)-oxazolones: [4+2] cycloaddition versus [4+3] cycloaddition/nucleophilic trapping [PDF]

, 2002
The use of different aluminum derivatives in the reaction between cyclopentadiene and (Z)-2-phenyl-4-arylidene-5(4H)-oxazolones, and in particular the use of different equivalents of the reagent, allows the modulation of the synthesis of the norbornane ...

Mucosal‐Associated Invariant T Cells in Health and Disease

MedComm, Volume 7, Issue 10, October 2026.
The roles of MAIT cells in health and disease and their therapeutic applications. In healthy individuals, riboflavin metabolites secreted by commensal bacteria at mucosal sites are presented by MR1, leading to the activation of MAIT cells. Activated MAIT cells can maintain the barrier integrity of mucosal tissues in a steady state or migrate to the ...

Recent Applications of Propylene Carbonate as a Solvent in Sustainable Organic Synthesis

ChemSusChem, Volume 19, Issue 17, 14 September 2026.
This review evaluates propylene carbonate (PC) as a non‐toxic green solvent in organic synthesis, highlighting its performance in key reactions including cross‐couplings, asymmetric hydrogenations, peptide synthesis and biocatalysis. Across these processes, PC delivers yields comparable to conventional and alternative green solvents.

Herbal Extracts and Plant‐Derived Bioactives in Atopic Dermatitis: Evidence, Mechanisms, Pediatric Safety, and Translational Priorities

Food Science &Nutrition, Volume 14, Issue 9, September 2026.
Food‐derived bioactives, herbal extracts, and standardized botanical products are being investigated as adjunctive strategies for atopic dermatitis. Their biological activity is shaped not only by plant source and nominal dose, but also by fermentation, drying, heating, extraction, food‐matrix binding, gastrointestinal transformation, and formulation ...

Design of Fuel‐Dependent, Complex‐Coacervate‐Based Synthetic Cells

Chemistry – A European Journal, Volume 32, Issue 31, 18 August 2026.
Fuel‐dependent synthetic cells form and persist only in the presence of chemical fuel, decaying under starvation. We establish design rules for hexapeptide‐based coacervates, showing that tryptophan enhances polyanion binding, extends lifetime, and reduces waste sensitivity.

Contribution of One‐Electron Oxidation of Purine and Pyrimidine Bases to the Photo‐ and Radiation‐Induced Damage to Cellular DNA

ChemPhysChem, Volume 27, Issue 15, 14 August 2026.
One‐electron oxidation of purine and pyrimidine bases of isolated and cellular DNA generates related reactive base radical cations that are converted into final decomposition products through deprotonation and hydration. In the case of guanine, the most susceptible nucleobase to one‐electron oxidants, 8‐hydroxy‐7,8‐dihydroguanyl radical, thus formed by
