A Blood‐Brain Barrier‐Penetrant Ag(III) Corrole Compound Rescues Alzheimer's Disease Pathology by Targeting Aβ42‐Induced Oxidative Stress

Advanced Science, EarlyView.
The newly designed metallo‐corrole (Mor‐Cor)Ag(III) with a morpholino group exhibited promising therapeutic potential for Alzheimer's disease. It significantly reduces reactive oxygen species (ROS), decreases GFAP expression, increases neurite length, and decreases cell death compared to other similar metallo‐corroles. Abstract Alzheimer's disease (AD)

Cathode Electrolyte Interphase Engineering by Quaternized Chitosan for Stabilized Li–SPAN Batteries

Advanced Science, EarlyView.
In this work, quaternized chitosan (QCS) is reported as an additive optimizing the sulfurized polyacrylonitrile (SPAN) cathode/electrolyte interphase (CEI). Its high positive charge density adsorbs PF6− anions, enriching the Helmholtz layer with aggregates. This promotes rapid anion desolvation, forming an anion‐derived CEI enriched in LiF.

Reaction of Nα-acetyl-L-histidine with diazomethane: A model esterification reaction of carboxylic groups in the presence of imidazole rings

Grasas y Aceites, 1996
The reaction of Nα-acetyl-L-histidine with diazomethane was studied in order to analyze the esterification reaction of a carboxylic group in the presence of an imidazole ring. The reaction produced the expected Nα-acetyl-L-histidine methyl ester (1) as a

Triplet Energy Transfer‐Driven Intermolecular [2+2] Photocycloaddition of Acyclic Imines and Indoles: Facile Access to Azetidine‐Fused Indolines

Advanced Science, EarlyView.
An intermolecular aza‐Paternò‐Büchi reaction of indoles and acyclic imines is enabled by visible‐light‐driven triplet energy transfer, providing azetidine‐fused indolines up to 93% yield for 30 examples and providing a novel protocol to access previously inaccessible scaffolds. ABSTRACT Currently, successful examples of the aza‐[2+2] photocycloaddition
